LANDSCAPING PROJECTS TO ENHANCE YOUR CURB APPEAL

For many homeowners, landscaping projects are about more than beautifying your lawn area, they're about increasing your curb appeal and the value of your property. Below are three landscaping projects any homeowner can undertake that can enhance your home's value and curb appeal.

1. Create an outstanding presence in the front of your property with a top quality mailbox and post.
The first element that guests see as they arrive at your property is the mailbox and post. Quickly, one can arrive at an impression of your property based solely on the appearance of the mailbox and post. 
Is it purely a no frills, functioning item? Is it dilapidated? Most importantly, does the mailbox and post add value to your property? A straightforward project to consider is updating your current mailbox. Transform that utilitarian item into a structural element that will command respect. 
During the material selection process, keep in mind that the goal is to select product that is of a high quality construction and will stand strong amidst harsh weather. I encourage you to have the house number and street name lettered on each side of the mailbox to serve as an address marker for future guests. 

2. Consider a post light in your future landscape projects and add a sense of drama to your landscape. 
Illuminate the entrance to your house with a post light. Landscape projects should not be limited to plantings, trees and turf. Expand the design process to include lighting and you will have an aesthetic and functional impact. 
A carefully placed light post adjacent to the walkway illuminates the immediate area and provides a structural element to the landscape. All too often, the walkway leading to the house entrance is not illuminated, creating the feeling of uncertainty when traversing the area. The power of light has the ability to highlight the texture of the walkway and provide a welcoming feeling after dusk. 
A personal preference of mine is to select a product that has character. Suggestions include an oversized cap, detail moldings and overall dimensions that create a feeling of stout rather than skinny and slender. The goal is to complement the house, add value and make the entrance a bit grander. Although this project involves a licensed electrician to make the electrical connections, this should not be a deterrent. 

3. Neighbors are great, but privacy is needed to enjoy your outdoor space. 
Neighbors are great, but during outdoor activities you may suddenly feel like you are on display. What is needed is some personal space away from the view of the neighbors and passers-by. Rather than installing a conventional fence along the property line why not consider a natural alternative with landscaping. 
Landscaping design is all about assessing the situation and creating a functional yet aesthetic solution. Material selection will be the key to this project. Evergreens, plants and trees that stay green all year will provide a natural screen. If space permits, trees would be the preferred material selection.

LAWN CARE

A homeowner's guide to types of grasses, lawn care tips, useful equipment, how to hire a lawn care company and no-maintenance alternatives to the traditional lawn.

Top 10 mowing tips

Change directions: Cut the lawn using different patterns. This will prevent ruts from forming and it will also encourage the grass to grow tall and straight.

Mow dry grass: Cutting wet grass isn't very effective. The grass will not cut evenly when it's wet and can clog the mower.

Sharpen the blade: Have the blade sharpened at least once a year. A dull blade rips the grass, creating an uneven look, damaging your lawn and leaving it exposed to diseases and parasites.
Don't mow your grass too short, and don't cut more than one-third of its height at any one time. 

Overlap: It's tempting to get the most out of every pass and minimize the amount of overlap, but it's not the best technique. Overlapping every pass by three inches or more will result in a smooth and even lawn.
Tall grass is good: As grass grows taller, its roots go deeper, resulting in a healthier lawn that requires less watering. The grass will also fill in nicely, providing a great safety net against weeds. Cutting the grass too short causes stress on your lawn. Over time, repeatedly cutting it short will result in turf that has bare spots and is highly susceptible to cold, extreme heat, pests and diseases.

The one-third rule: Never cut the grass by more than a third of its height at any one time. If the grass has gotten too tall, cut it back by one-third, wait a few days and then cut it again.

Don't be not understanding: Choose a mower with a safety handle that will shut down the mower when released. Never allow people to ride on the mower deck as this can result in serious injury. Wait until the blade has completely stopped spinning before going near the deck to remove clogs.

Clear the lawn: Your mower has the power to turn any rock or stick into a flying projectile that can harm nearby people. Clear the lawn of toys and other objects before cutting. Watch for objects buried in the grass as you are cutting to avoid problems.

Mow early in the day: When possible, cut the grass early in the day, as soon as the dew has dried. This will give the grass time during the day to gather fresh nutrients.

Cutting hills: When working on a hill, cut across the slope. Never go up and down the slope for safety.

Fertilizers & chemicals

Maintenance is vitally important to proper lawn care. This includes proper mowing but also includes watering and fertilizing. Watering the grass is especially important in dry climates where there may be several weeks without rain. This allows the grass to maintain a proper growth rate and reduces the risk of grass killing diseases.

Fertilizing is worthwhile in any climate but a necessity when the soil lacks nutrients. The most important ingredient in fertilizer is nitrogen which is vital for the continued growth of thick and healthy grass that can spring back into shape after being crushed by something that has run over it. Higher nitrogen is essential for maintaining grass that is already established.

Overuse of chemicals: Pesticides can be essential to preventing infestations and disease but should be used with great caution. Some pesticides are very harsh on a lawn and can cause as much new damage as it prevents in old damage. All pesticides should be checked for natural ingredients which should take preference over harsher chemical based pesticides.
Lawn abuse is common, especially among families with pets. Everyone wants to enjoy their lawn but must be careful not to put too much pressure on the grass to stay healthy and get constantly trampled. Pets also cause issues because their urine actually burns the grass and can cause yellow discoloration.

Disease prevention:Even if every step above is followed, some lawns will manage to get diseased. Brown patch disease is treated the same way it is prevented, with proper watering. It can also be treated by reducing the amount of nitrogen in the ground. There are many diseases that can affect a lawn including fairy rings, red thatch, and dollar spots. Most can be treated by returning to proper maintenance habits but if the disease is not resolved after a week of proper maintenance, it may be necessary to call in a professional.

Types of grasses

Given the expansive land area in many countries homeowners in different regions will experience varying climates and growing conditions that may challenge the type of grass they can grow in their yards. In the north, where the growing seasons are short and the climates extreme, certain varieties of grass will thrive. In the south, where the soil may be clay or sandy with mild winters and long hot summers, those same grasses may not do as well. A lawn care specialist can help determine which type will thrive on your lawn.

Cool weather grasses:

Bentgrass: This type of grass tolerates close mowing, but does not tolerate hot, dry weather or cold winters. The variety is better for golf courses, since it is low maintenance, can withstand droughts and tolerates high traffic. Unfortunately it does require constant mowing.

Kentucky bluegrass: The most popular of the cool season grasses, Kentucky bluegrass spreads well and fills in bare spots. Bluegrass goes dormant in hot, dry weather and during the winter, but performs poorly in extreme shade. Be sure to water regularly and fertilize often to keep this grass healthy.

Rough bluegrass: This type of grass does well in cool moist conditions, performs well in lower temperatures and responds well to fertilization and irrigation. Unfortunately it is highly susceptible to insects and diseases.

Red fescue: This grass flourishes in cool shaded sites such as camps, resorts and cabins. It requires little in the way of water, fertilization or mowing.

Annual ryegrass: Mostly used as forage for animals, ryegrass can be used as a mix with other grasses to provide the dominate grass with more thickness and density.

Perennial ryegrass: Best for moist and cool environments, and where temperatures are not extreme. When used in the south, it has the highest maintenance requirement. Mowing, watering, fertilization and pest management is required for health.

Warm weather grasses

Bahia: Resistant to drought, disease and insects, Bahia also survives in sand or clay. Predominately used along coastal areas , Bahia grass needs to be frequently mowed during hot weather.

Bermuda: Drought resistant, yet adaptable to various soils, Bermuda grass is used frequently for lawns in the south. It is also used for athletic fields, parks and golf courses. It does not flourish in the shade, but it can handle large amounts of traffic.

Centipede: This grass is slow growing, but it is ideal for lawns since it is low maintenance and does not require much fertilization or mowing.

Saint Augustine: Very popular  Saint Augustine is good for coastal regions. However, it performs poorly in cold climates and does not tolerate high traffic well.

Zoysia: Extremely drought tolerant, Zoysia is deep rooted, does well on sandy seashores and handles traffic well.

12 great lawn care tools

You don't necessarily need to own all of these -- for example, a rototiller can be rented when needed -- but here's a primer on each tool and its uses.

LAWN MOWERS -
Types: Manual reel, gas push, electric push, riding, lawn tractor, zero radius and robotic
Purpose: Used to cut grass. Lawn tractors can be utilized as a multipurpose vehicle for hauling, plowing and other outdoor lawn and gardening tasks, as well.
Maintenance: The blades on all lawn mower models must be sharpened to provide desired results and even cutting services. All mowers except for the manual reel require regular oil changes and tune-ups to ensure the engine is properly functioning.

EDGERS -
Types: Electric, gas powered
Purpose: Cuts a trench along walkways, driveways, around flower beds and other landscaping, giving the lawn a more pedicured look.
Maintenance: The motors on these pieces of equipment require regular tune-ups to ensure that they are well lubricated and operational.

WEEDEATERS -
Type: Electric, battery-powered and gasoline
Purpose: Removes grass and weeds in areas that are hard to reach with the lawn mower. These areas include around trees, under bushes and against buildings and walkways.
Maintenance: The strings on weed eaters need to be changed or refilled. Spark plugs must be checked. Most models require you to oil the motors properly, as well as the rotating mechanism for the string at the bottom.

LEAF BLOWERS -
Types: Gas, electric
Purpose: Provides an easier method of removing leaves and other light-weight debris from the lawn for easier clean-up. It can also be used to blow water from paved areas, rain gutters and snow from driveways.
Maintenance: Electric leaf blowers require minimal engine maintenance for tune-ups. Gas powered leaf blowers require regular tune-ups and maintenance to keep up with the demands of a two and four cycle engine.

AERATORS -
Types: Core/plug, spike, gas-powered and manual
Purpose: Used to control the law thatch and reduce soil compaction so that water and nutrients can reach the roots of the grass and other vegetation within the yard.
Maintenance: When you are finished using the aerator, the spikes should be rinsed off with a garden hose and allowed to dry thoroughly if storing in a dark area. This will help to prevent rusting. Gas powered aerators will need seasonal tune-ups performed. If used often, inspections on oil, spark plugs and other components of the engine should be inspected.

FERTILIZER SPREADERS -
Types: Rotary, drop and sprayer
Purpose: Used to evenly distribute fertilizer over lawn and gardening surfaces.
Maintenance: When you have finished using the fertilizer spreader you will want to spray the holding compartment out with a garden hose. It is important to ensure that excess fertilizer is not left stored with the equipment, as this can cause explosion hazards. Make sure sprayer model spreaders are not clogged by flushing clean water through the nozzles

RAKES -
Types: Various shapes for different tasks.
Purpose: Used to remove leaves and debris from the lawn, under bushes, in flower beds and other areas where debris may gather
Maintenance: Spray the rake with a garden hose when you have finished using it and before storing it. If the forks for the rake are connected to the handle with a screw or rivet, you will want to inspect this prior to using it.

SHOVELS -
Type: Various shapes and sizes for different tasks.
Purpose: To remove soil, grass and other materials.
Maintenance: Spray the shovel or spade with a garden hose after using it. If the head of the shovel or spade is connected to the handle with a rivet or screw, inspect this before using the tool.

PRUNERS -
Type: Manual, gas, electric
Purpose: Used to remove dead or undesired limbs, leaves and branches from bushes, trees, flowers and other plants around the yard for a more manicured look.
Maintenance: Remove dirt and debris from the blades when not in use and prior to storing to prevent rusting or damage. Blades must be sharpened periodically for desired results.

GRUBBING HOE -
Type: Manual
Purpose: Acts as an aerator between dirt pathways and in between landscaped areas or vegetation.
Maintenance: Spray the blade of the grubbing hoe with a garden hose to remove dirt and debris. The blade must be periodically sharpened.

GRASS SHEARS -
Type: Manual
Purpose: To trim hard to reach grass patches, dead leaves and small branches from bushes and flowers.
Maintenance: Blades need to be periodically sharpened.

ROTOTILLER -
Type: Manual, gas, electric
Purpose: Similar to an aerator, except that the rototiller is able to work through harder surfaces and in a larger patterned area. Rototillers are generally used in gardening areas and flower beds at the beginning of planting season.
Maintenance: Blades should be sprayed off with a gardening hose to remove excessive dirt and debris. Blades often need to be sharpened. Tune-ups must be performed on the motors to ensure they are operating properly.

Hiring a lawn care service

While some homeowners take great personal pleasure in caring for their beloved lawns, for others it's just a big chore that's hard to keep up with.

 If you're thinking of hiring a lawn care company, here are some tips:

Get an on-site estimate: Having the company come to your house and assess your lawn and its needs will ensure you receive the right treatment and maintenance plan needed for growing a healthy lawn.

Avoid quick fixes: If your lawn is in distress, stay away from self-proclaimed magicians who claim to work miracles. Getting a damaged lawn back into healthy stages usually takes time.

Chemical check: If you're considering a chemical treatment to be applied to your lawn, make sure the professional you hire is certified to apply such chemicals.

Do your homework: Make sure the company is insured, and look for someone with good recommendations from past customers.

Lawn alternatives

Native plants: When using plants that naturally grow in your area, you will find that they are usually drought resistant and give a variation in appearance from grass. Moreover, native plants are easily integrated with landscaping projects. Clover and moss are among the variety of plants used to cover lawns.

Artificial turf: Made of recycled materials including used tires, artificial lawns require no water, fertilization, weed killer or mowing. This choice is good for places where plant growth can be difficult.

Stone: Stone or gravel provides the owner with a variety of colors and sizes. Planning and intense labor is needed to establish the stone lawn, but once in place, it just needs to be hosed down, and sprayed with weed killer on occasion. If you live in an area where grass won't grow or don't have it in your existing landscape, consider using pea gravel as a pet-friendly surface. A small, loose, rounded, pebbly stone, pea gravel can be raked easily to remove pet and plant debris. It makes good paths, and is a reasonable, dust-reducing mulch. When choosing gravel, keep your pet's paws in mind. Smaller gravel can get stuck in between larger paws, which leads to it being tracked inside. Pea gravel also gets hot in direct sunlight, so it might be best for shaded areas.

Cedar bark mulch: Mulch is a good alternative for homes needing a grass alternative, as it also comes in a variety of sizes and does not heat up as gravel does.

Leaf removal

A professional leaf removal company can help quickly clear large yards.
 
For do-it-yourself leaf removal, there are a few different tools that you should have on hand. Most of what you need will be determined by how big your yard is and how many trees you have dumping leaves onto it, but there are some general necessities that you'll need no matter what. For smaller yards, a heavy-duty rake, some gloves and a strong back are generally all you need.
For larger yards, you will need some sort of powered leaf-collection tools if you plan on getting your lawn finished in a reasonable time frame. This can be anything from powered sweepers to leaf-blowers, and they are absolutely necessary if you don't want to spend your entire weekend getting rid of leaves. Next, you need something to haul the leaves with. This can be anything from a truck to a wheel-barrow, with a truck being more preferable.
Finally, disposal is an aspect of yard cleaning that people don't always seem to take into consideration. Once you clean up all the leaves, you'll need to get rid of them. Some people simply use the “lawn waste” pickup provided by their garbage company.

Hiring a professional
A leaf removal company can help homeowners maintain a leaf-free lawn.  They have the right equipment and the manpower to get the job done efficiently and quickly.
There are a few different things that you can do to help ensure that you don't get bombarded by too many leaves in the fall. Most obviously, you could replace your landscaping with evergreens, eliminating the problem entirely. Next, you can have the branches trimmed so only enough of the tree remains to remain attractive. While some of these are more difficult than others, they will all result in lower numbers of leaves hitting your yard.

LANDSCAPING YOUR YARD

Landscaping your property can be a major undertaking, and a long-lasting one. Start with a clear plan of what you want to achieve, then decide what parts you want to do yourself and what would require a professional. If you're thinking of selling your home, a bit of landscaping can give it the 'curb appeal' it needs.

 Planning your landscaping

Because we don't all live in areas where it's 85 degrees and sunny year round, it's important to plan ahead when considering any outdoor landscape projects. Planning ahead will give you ample time to do your research and make sure you're hiring the best professionals in the area. It will also help you get a clear idea of how you want your outdoor space to look and give you time to compile your wish list.
Here are some things to consider:

• Decide which parts of the property you want to landscape. You don't have to do the whole yard at once. Break it up into projects or phases. This makes the tasks more manageable and affordable.
• Think how you'll use the landscape. Will it be for outdoor entertaining? Are you trying to gain privacy or dampen noise?
• Collect landscape images that appeal to you. Try sketching a rough idea of what you have in mind. Visit garden centers and make a list of plants that interest you. Present these materials to the landscapers under consideration and listen to their advice. Sometimes designs or plants may look good but aren't well-suited to your particular property.
• Decide if you're going to do the job or hire someone. If your property has slopes, drainage issues or other kinds of potential engineering problems, hiring a landscape architect or designer may be your best option.

 Tips on hiring help
Follow these tips to find the right expert for your needs:

1. Have an idea of what your ideal landscape looks like. This will help the professional understand what you're looking for; however, be open to ideas. They know what will work best for your space.
2. Get recommendations from others.
3. Make sure the landscaper you hire meets state and local certifications and licensing requirements, if any.
4. Obtain a signed copy of any contracts and work orders.
5. Be prepared to go on site visits. Some professionals will ask you to view examples of past work or similar landscapes to what you're requesting.

What kind of expert do you need?

Here's a primer on several related professions:

Landscaper: These professionals can plant new trees and shrubbery; remove, modify and replace existing plants and materials, such as mulch; establish new planting beds; install sod or seed a new lawn; and provide routine maintenance. Some landscapers offer design services, but usually they work from plans the homeowner commissioned from a landscape architect or landscape designer. Many landscapers offer irrigation and sprinkler services, but there are also individualized specialists who can install these systems.

Landscape architect: If you aren't sure what you want, or if your grand plan requires changing the lay of the land, you may need to start with a landscape architect.
These professionals often work on large custom home projects, providing overall site plans for drainage and landscaping. They can also work on smaller, yet complex, residential projects. Often landscape architects are involved in commercial and municipal projects as well. They have advanced education, professional training.

Landscape designer: Many have horticulture backgrounds or nursery experience and can design a landscape for a new home or renovate an existing area. They're very good at providing a blueprint for your yard, indicating where each plant and feature should be placed. Typically, designers are trained under the apprentice system and aren't licensed.

Certified arborist/tree service: Specialize in pruning, disease and pest diagnosis and treatment. Depending on their experience, they can provide suggestions for tree replacement, install lightning protection, or cable and brace trees that have broken limbs or are leaning.

Gardener: A person with or without horticultural education, and often performs routine garden chores similar to a landscaper. They perform simple maintenance chores like dead-heading flowers, feeding and repotting plants. The more education or experience the gardener has, the better he/she will be able to help you pick the plants, flowers and vegetables that will thrive in your location.

Horticulturalist: Help with plant problems and diagnosis of diseases and problems. Are usually knowledgeable in plant cultural requirements and can advise watering and feeding schedules.

Contractors: Though perhaps not the first profession that comes to mind when you think of your landscape, hiring someone to install an outdoor kitchen or living area, for example, would take the work of contractors or specialists. When researching who to hire, ask your local landscaping company if they install outdoor kitchens.
Many landscaping companies offer outdoor living space services and other companies brand themselves as outdoor kitchen installation specialists. Because of the construction, masonry, plumbing and electrical work needed to make the kitchen function; you might need to call upon individualized specialists

Lighting your landscape

There are several types of landscape lighting, depending on the effect you wish to create:

Downlighting: Casting light downward to increase drama and beauty.

Uplighting: Casting light upward to highlight texture, size and color.

Moonlighting: Usually globe-shaped, they cast a soft, natural light glow.

Spotlighting: Casting light to specifically focus on a garden feature, such as a flower bed or sculptural piece.

Pathlighting: A series of lights set low to define a walkway for safety and increased aesthetic appeal.

Silhouetting: Incorporating background lighting to accent structural features.

Grazing: Directional light placed at an acute angle, to emphasize texture

Landscaping for curb appeal

First impressions are important, and that goes for your home, too. Whether you’re trying to attract potential buyers and achieve the highest resale value possible or wanting to make your home stand out from the others on the block, your home’s landscape can make or break its curb appeal.

Making a great first impression

Landscaping can give your home the 'curb appeal' needed to sell in a down market.
Make sure your yard is clean and tidy. A neatly mown, edged and debris-free landscape offers the impression of a home that’s been well cared for. Keep the front walkway clear and uncluttered, and consider landscape lighting to create a warm and welcoming entrance.

Because you want your house to be the focal point, it’s important to stay on top of pruning. You can't showcase your home if it can't be seen from the street. Prune overgrown trees and shrubs to frame and show off the house. Branches in contact with the house are a red flag for appraisers checking structural integrity and potential pest damage. Safety issues, such as dead wood and dangerous trees, are sure to show up on costly work orders.

On the other hand, if your front yard is devoid of plants, consider planting a tree as a focal point. Consider color. First impressions are largely emotional. Use color to attract and focus attention on positive aspects of the landscape. A single substantial container brimming with blooming bulbs and fresh spring color creates a bigger splash than the same number of plants scattered throughout the front yard.
Maintenance is especially important with color — faded bulbs and burned out plants mid-summer are off-putting. Plan to trade out and refresh container plantings with seasonal shifts.
If you’re thinking of putting your home on the market, Realtors say the online photo is the first step of curb appeal, so make sure you have a photo of your home’s exterior at its best.

Land surveying

When building a fence, planting trees or installing outbuildings contracting with a land surveyor before making changes to a property can prevent clashes with neighbors and city code violations.
Land surveyors place iron rods or other markers at the corners of a property to establish boundary lines. Essentially, land surveyors determine where one property ends and another begins. They can also provide other services including topographical and flood elevation surveys.
While a survey is not needed for every kind of landscaping or outdoor home improvement project, any plan that includes working near a property line has the potential to create a dispute with a current or future neighbor.
Land surveying is most important before erecting permanent, expensive structures near boundaries. That includes wood fences, rock walls and other barriers that are difficult to move. Trees and shrubs can also be expensive, and planting them too near a property line could result in a neighbor forcing them to be removed.

Hiring a land surveyor is a good idea before starting construction on outdoor projects like building a fence or landscaping.
 
Storage sheds and other outbuildings are often erected near property lines, but a recent, accurate land survey is necessary to make sure buildings comply with utility easements and other building code requirements.
Even if the relationship with an adjoining neighbor is friendly, the house could later be sold to someone who insists on complete compliance with property boundaries. Other factors like blocking a neighbor’s view or creating unwanted shadows on his or her property should also be considered.
Land surveying is also useful to homeowners trying to prove that a neighbor has encroached on their property. The plot a surveyor provides could be enough evidence to win a civil or small-claims court case.
Hiring a land surveyor
Because of the need for a license and specialized equipment, land surveying is never a do-it-yourself project. Professional land surveyors are easy to locate, however. In most parts of the country, they are known simply as surveyors, and they are sometimes part of civil engineering or land use planning companies.
Finding firms that offer the service is easy, but choosing a well-regarded firm with proper  licensing. A written contract is also an industry standard, so it is best to avoid surveying contractors who refuse to provide one.

Like hiring any professional, choosing a land surveyor involves choosing a trustworthy, polite and friendly company that is willing to answer your questions. Some questions to ask include:
  • Do you regularly perform this type of surveying?
  • Will my lawnmower damage or interfere with the markers you place in my yard?
  • Will you be filing your report with any governmental agency, and if so, where will it be recorded?
A land surveyor should be willing to walk the property with the homeowner after the survey, pointing out where markers have been placed and answering any additional questions.
When homeowners turn to the services of a professional land surveyor before starting an outdoor project near property boundaries, they can avoid creating problems that could be costly and difficult to fix after the project is complete

HOW HARDSCAPING CAN BENEFIT YOUR LAWN AND LANDSCAPE

Hardscaping is the use of hard materials such as rock, stone, concrete and pavers. These hard materials are what bring value to your landscape design. Hard materials like these are the things that require no replacement. As great as this seems to be, to have a Florida friendly garden, you still need other elements.

Is hardscaping the remedy?

If you are having trouble growing grass or plants due to poor soil composition, or if an area stays wet for long periods of time, a hardscape may be a good remedy to that problem. Hard materials such as stone and rock absorb heat from the sun and can dry soil near and under it. Concrete can do the same thing. 
If you look at how fast a wet driveway can dry after a rain, you will notice that once the sun is back out, it doesn’t take much time. Next time it rains, pay attention to the street. As the rain hits the hot pavement, it quickly turns to vapor and goes right back into the atmosphere. This is good for standing water, but to have a good balance, you still need plants.

Knowing where to plant

Planting live materials inside of rock areas is not a good practice and the results are generally not positive. As mentioned above, rocks can absorb heat and dry the soil, so placing a live plant in that situation and expecting it to do well is a recipe for disappointment. 
Plants should be in an area that can hold moisture yet drain well (so the roots don’t rot). Wood mulch is best for ground cover around most plants, but there are some that can do well inside of a shell bed. Seashell is another form of hardscape material, and some plants can actually do well in this environment.

How much is too much?

The purpose of hardscaping  is to provide good drainage and minimize run off. Run off should be routed to planting areas (not storm drains) so drainage can occur there. 
This is the ideal way to utilize a hardscape in your yard. There should always be a balance of hard and soft materials such as mulch or bark, live plants and maybe a little turf (if you have to have grass in your yard).
Too much hardscape can lead to a “heat island effect,” which is when surfaces that were once permeable and moist are now impermeable and dry, creating an island of higher temperature around the building. Shade trees are a great way to reduce this risk. Proper planning is also a great way to reduce the chances of causing this effect. Like any other improvement project, if you fail to plan, plan to fail.
