Understanding the role of insects in gardening

While many types of insects, birds and animals seen in the home are unwanted intruders, others play a vital role in pollinating plants and moving seeds from one place to another.  In fact, without these animal and insect helpers, most plants would be unable to reproduce.

Even though most gardeners understand how important this cycle of pollination and seed disbursal is, few fully understand why it occurs, or how it benefits both the plants and the animals. 

The rewards of pollination and seed disbursal to the plants are easy to determine – they get to spread their seeds far and wide, and start new plants in far off locations.  The rewards the insects, birds and mammals derive are many as well, and they include:
Nectar – nectar is actually a sugary solution, and therefore it is highly prized by all kinds of animals both for its good taste and for the ample energy it provides.  Getting at this nectar is what prompts most pollinating insects, birds and animals to do such a good job.  Nature has provided plants with various ways to attract pollinating insects, birds and animals.  Many types of flowers store their nectar in special glands called nectaries.  These nectar glands are most frequently found in flowers, but they are also sometimes contained in leaves or other parts of the plant as well.  Most plants are designed to protect their nectar stores from non-pollinating insects and animals, through the use of special storage locations that only pollinating insects can reach, for instance.  
The use of nectar and the plants, insects, birds and animals that depend on it is a fascinating study in co-evolution.  The sugar concentrations of many plant nectars have evolved to match the energy requirements of the types of animals, birds and insects that pollinate them.  For instance, bees require a 30-35% concentration of sugar in order to make the honey needed by their larvae in the winter.  Therefore, bees will not visit flowers whose nectar contains less than 30% sugar.  Therefore, the flowers and plants that depend on bees for pollination have evolved high concentrations of sugar in their nectar to attract these pollinators.
Pollen – Pollen is also used by flowers and plants to attract the insects, birds and animals they need.  Pollen is eaten by bees, and it is also used to make a substance called bee bread, which is a high protein combination of pollen and nectar.  This bee bread is used to feed the larvae, which require a high concentration of protein to grow and thrive.  Some plants, such as peonies, poppies and roses, use only pollen as a reward and produce no nectar at all.  Other types of plants produce two types of pollen – their normal pollen and a sterile pollen with is attractive to pollinating insects.  This evolutionary strategy ensures that the good tasting pollen will be eaten while the reproductive pollen will be spread to other areas by the insects, birds and animals that visit the plant.
Of course, this pollen and nectar does the plants no good if the birds, insects and animals cannot find it, and plants and flowers use their bright colors and strong scents to attract these animals and let them know that pollen, nectar, or both await them. 
Some pollinating species rely primarily on their sense of sight, and the bright flowers are used to attract their attention.  Other species, particularly nocturnal ones, rely primarily on smell.  It is the scent of the flowers that attracts these scent oriented pollinators.

Using perennials in your garden

Perennials are favored by many gardeners, not only for their ability to bloom for several seasons, but for the wide variety of colors, shapes and sizes they come in as well. 

Whereas annuals must be planted anew every season, perennials can be left in the ground to bloom for several seasons.  This makes gardening with perennials less costly and means that the perennial garden can be easier to maintain. 

In addition, most perennials are very easy to work with, and the demands they place on their gardeners are usually quite low.  Sufficient water, good soil and abundant sunshine are all most perennials need to provide beautiful blooms all season longs.

There are several important considerations with perennials, however, given the nature of their growth.  Since perennials remain in the ground year after year instead of being started fresh every season, they are more prone to disease and insect infestation than shorter lived annual plants.  This means that the gardener must be on the lookout for any signs of disease or unwanted insects, since an unnoticed infection can quickly spread through the entire garden.

The best way to avoid disease and other problems in the perennial garden is to make sure the plants are as healthy and robust as they can be.  Healthier plants are naturally able to withstand disease and insects better than weaker ones, and an infection that would kill a weaker plant will be fought off by one in better condition. 

In addition, the gardener should be ready to immediately combat any diseases or infections that are found.  Keeping a supply of common fungicides and insecticides on hand is a good insurance policy when trouble strikes.  Perennials should regularly be inspected for signs of problems, such as wilting leaves, spots or holes in the leaves.  These can all be warning signs of problems with disease or insects.

It is a good idea to get in the habit of checking for such problems every time the garden is weeded, watered or otherwise tended to.  When watering perennials, it is generally best to water them deeply once a week instead of spraying them with a hose more often.  It is important not to encourage standing water on the leaves, as this can leave the plants vulnerable to fungal infections and other problems.  It is also important not to water the plants during the heat of the day, since watering then could cause tender foliage and flowers to suffer burns.

Watering deeply and less often is almost always preferable to watering more often and more shallowly.  Investing in a good soaker hose or drip irrigation system is a great idea for any perennial grower.

Since the key advantage of working with perennials is their ability to come back year after year, it is important to care for the plants properly after the current growing season has ended.  Most perennials should be pruned once a year, but it is important to pay attention to the specific requirements of each variety.  While some perennials benefit from a radical pruning in the winter, others need less pruning.  It is important to understand the exact requirements of your particular plants.

Lawn Care Basics

Lawn care is often the most basic of landscaping chores. Taking care of the yard is practically an American institution. There is much pride in ensuring that you have a healthy and beautiful lawn. Additionally, it is satisfying to know that you can take care of your lawn on your own for much less than paying someone else to do it. Plus, you get that sense of satisfaction knowing that you did a great job on your lawn. But in order to have a great looking home landscape, there are a few things to keep in mind regarding lawn care basics. But once you have the basics down, and if you keep with them, there is no stopping you from having a great looking lawn.

Before you do anything, like mowing, you need to make sure that you clean the lawn. This means raking up leaves and debris, and clearing the area of unwanted brush. If you are looking to have a level lawn, getting rid of bumps and or dips, there are some things that you can do. To get rid of little valleys, you can fill the holes with topsoil and then add grass seed. Bumps can be removed by using a garden spade to cut an X in the raised area. Peel back the sod and then remove the soil as needed before replacing the sod. By cleaning and leveling your yard, you will make it easier to mow the lawn, and your yard will have a pleasing uniformity of appearance.

Mowing the grass should be done regularly. Depending on where you live, and how fast your grass grows, this may need to be done once every week or once every other week. You should adjust the lawn mower blade so that it does not cut off more than one third of the grass’s height. The surface area of each blade of grass is important in sustaining the health of the lawn. If the grass is cut to short, an environment especially conducive to disease is created, and this can result in a rather unhealthy lawn.

One of the essentials of lawn care is making sure that you do not have too much soil compaction. Over time, your soil will become compacted and harder beneath the grass. This begins to cause problems like moisture penetration and grass root restriction. Aeration makes it possible for your soil to “breathe” a little easier. There are two types of aeration. One is the kind called “plugging,” where a special device removes clumps of soil, about the size of a finger, from out of the ground. The other kind simply punches holes into the soil. The point, however, is that this allows water seep down better (preventing erosion and drying out), as well as providing room for helpful organisms like earthworms to live. It is usually possible to rent an aerator if you do not wish to buy one. It is good to aerate about once every year or two.

Fertilizer can help your lawn grow as well. While it is not strictly necessary, and while it is possible to grow a healthy and attractive lawn without the aid of fertilizers, many people find them very helpful. It is important not to apply too much, however, as this can result in the death of your lawn, and also can result in harm to the environment as the excess fertilizer is washed away. Fertilizers usually come in liquid or granular form. Liquid fertilizers act fast and require application every two to three weeks. They can be applied with a hose-end sprayer or by using a watering can. Granules are dry and require that you water the lawn immediately after their application. You most often use hand spreaders or mechanical spreaders to disburse these types of fertilizers. They can last eight to twelve weeks.

When you use fertilizer, you should be aware that it might be harmful to let your children play on the lawn for a few days. You need to make sure that the fertilizer has been absorbed below the surface before allowing yourself or others to play on the grass. Many conscientious landscapers find that they do not need fertilizers to create a successful lawn.

Preparing to Build Wooden Fences in the Landscape

While chain link fences are use in some landscapes, most people prefer to make use of wooden fences when building an attractive landscape. This is because wood is a rather versatile material that can be made to look a variety of ways. Installing your own wood fence requires time and energy, but it is often worth it as you can have privacy without detracting from the look of your landscape. Even if you do not build a very tall fence, a wood fence around your yard can prevent unwanted animals (like dogs) from getting into your yard. But before you begin, there are a few things to know about preparing to build wooden fences.

It is important to know the basic elements of the wooden fence before you get started. These are the elements that almost every fence consists of, and are almost universally necessary to build an attractive and effective fence. You will need posts. These are vertical elements that are placed in the ground. They rise above the ground, of course, and properly set posts are essential for keeping all of the other components in place. Some posts extend above the top of the fence for decorative purposes and others are only as high as the fence itself. Another important element of support is the rail. Rails act as spanners, connect the posts. They run parallel to the ground and serve as the horizontal support elements. Almost every fence style makes use of top and bottom rails, and some also utilize middle rails. Finally, panels are required for the successful fence. Sometimes the panels are referred to as boards. There are open fence styles that make no use of panels, but panels of latticework or even just straight boards are the main elements that provide privacy.

Next, you should prepare to install your wood fence. If you would like your installation to go smoothly, you should plan and prepare so that everything is in order before you begin. It is virtually impossible to complete a landscape project without any hiccups, but with a little advance planning you should be able to take care of things in a relatively smooth manner. The first thing you need to do is check with your local zoning or building board to find out the height or design restrictions. Additionally, chances are that you will need a building permit before you begin. You also want to make sure that the fence you build will be within the borders of your own property. If you need to have a survey beforehand to satisfy the neighbors, do so, as this can save you legal fees down the road if the neighbor decides to sue. Another thing of paramount importance is to find out from the local utility companies where the underground gas, electric, and power lines are located. Additionally, check with the phone and cable companies regarding possible underground lines they may have. It can be dangerous to damage such lines, and if you do so, you are responsible for the costs associated with repairing the damage.

Be sure that you have a plan for your fence, based upon the preparation discussed above. Know where you are going to place your posts beforehand, and have an idea of how high you want your fences. You should also have an idea of how deep your postholes will be. If you have properly planned your fence, then you will be able to complete it that much faster. Also, make sure you have all of the necessary tools on hand. These tools include a posthole auger, a shovel and a wheelbarrow (to mix concrete), a hammer and a punch, a power saw, a level, mason’s line, and a carpenter’s square. Many of these tools need not be purchased; it is possible to rent them for a reasonable price (especially the posthole auger, which many people do not own).

Once you have everything in place, you are ready to build a fence. Follow the plan carefully, and try to stick to your budget. When you have everything properly prepared beforehand, you will be surprised to realize how fast the work goes, and how good your fence looks as part of your landscape.

Protecting Your Landscape from Insects

Insects can cause significant damage to your landscape. This damage can result in costs to treat the damage or replace damaged plants. Managing insect pests is a very important part of landscape maintenance, and requires that you take an active role in protecting your plants and caring for them. Be sure to know what you are dealing with beforehand, and ensure that you are adequately prepared to combat insect pests, whether you use natural methods or synthetic methods.

The first thing that you need to recognize is that not all insects are pests. Some of them (like bees) actually provide helpful services and are part of a thriving ecosystem in your yard. Additionally, different insect pests cause different problems, and they should be treated differently. It is possible to treat most insects with pesticides, but it is important to note that when one uses these chemical solutions, they rarely distinguish between helpful insects and pests, and may kill insects that do no harm. If you can identify the pest that is causing a specific problem, then you can more effectively treat it using targeted methods of eradication.

For the best possible health to your landscape, prevention is the best way to avoid insect pests. There are many non-chemical management techniques that can be used to help prevent unwanted insects from even causing a problem. The best treatment is to keep plants in general good health. Healthy plants are more resistant to the vagaries of insect pests, and they will stand up to harsh measures if they have to be taken. Below are some general guidelines to help you have the healthiest possible plants and to help your landscape increase its defense against insects:

Choose your plants carefully. Make sure that they match the site in terms of soil type, drainage and sunlight received. Also select plants that are compatible with the climate in your region.

Plant varieties that are resistant to common pests. For instance, paper birch is especially susceptible to bronze birch borers, and may fall victim to these pests. Choose plants that are hardy and not often affected by the run of the mill insect.

Promote diversity by selecting plants that are resilient to different pests. Also, planting a variety of vegetation in your landscape can lead ensure that even if one particular plant is ravaged, that your entire landscape will not suffer. Diversity protects.

Promote the general health of your plants through proper care. Make sure that you follow a schedule of watering, pruning, mulching, and fertilizing. This will help the plants remain in good health.

Encourage natural enemies in the insect world. Insects eat other insects, and if you promote competition in that way, the populations will remain lower, and there will be less focus on your plants. A wide variety of flowering plants that bloom at different times throughout the growing season are especially good at encouraging natural enemies.

Monitor your plants regularly to ensure that an infestation does not have time to strengthen and take root. This way you can take care of the problem immediately. Some non-chemical methods that work very well in controlling insects are things like hard water sprays to keep aphid populations in check and cardboard or metal rolls that protect against cutworms. If the damage is not severe, it is possible to take no action against them, but this does carry with it a risk: it could become severe if not properly treated.

If you feel that using an insecticide is the only way to eliminate a pest problem that you have, be sure to use such chemicals with care. Determine whether the use of the pesticide will actually prevent significant damage from occurring. Try to treat the plants before the damage has occurred, so that the plant recovers better. If the insects have moved on, there is no reason to treat the plant, especially if damage has already occurred. The chemicals will affect the plant as well as the pests. Make sure you carefully read the label prior to buying your insecticide, and be sure to read the instructions before using. Also be concerned about how much you use. Too much insecticide can cause damage to your health, as well as to the health of your plants.
