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.

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.

Water Gardening

There are many new trends surfacing in gardening, and water gardening is one of the main new interests. Water gardening can be in the form of waterfalls, ponds, fountains, all of which can be enhanced by rock work combinations and lighting, plants, and fish. Water gardening doesn’t have to be a pond or natural water source either, it can consist of just a plastic tub, basically anything that can hold water.

The most important thing to consider in water gardening is probably the spot chosen. Since plants and fish both need plenty of sunlight, places in direct light away from trees and bushes is the best place. This will also help prevent leaves and debris from collecting in the water.

When planning for a water garden first decide the size you want. This will depend on how much money you are willing to spend because water gardening can get expensive if you opt for a large garden full of plants, rocks, fish, and lights. Also consider the size of our property, and the amount of time you want to spend with maintaining your water garden.

When you choose what type of aquatic plants you wish to have, remember that the plants should only cover about half of the water. Plants can be free floating, submerged, or marginal. Which you choose is all a matter of personal preference. Some plants are good for their scent, some provide more oxygen than others and will keep the pool health, and some are just beautiful. Fish are not only nice to look at but they are also very beneficial. Fish help keep debris at a minimum and help in controlling larva and other insects.

One of the main difficulties in water gardening is keeping water clear of algae. Algae problems are usually caused from too many nutrients in the water from feeding fish too often or from over fertilizing plants. If ponds are made correctly and are maintained properly algae problems and control will be kept at a minimum.

All garden pools regardless of size will need maintenance throughout the year. With proper planning you can ensure a healthy balance between living and decorative features of a water garden that can almost care for itself with simple maintenance inputs from you.
You can get rid of algae by reducing on the nutrients that cause the algae by cutting back on feeding and fertilizing, planting more plants, installing a filter system, or replacing existing water with fresh water. There are some chemicals that can be used, like copper compounds, but overuse can kill plant life and fish.

Water gardening doesn’t take anymore time than regular gardening, but obviously isn’t near the same thing. You may be the type person who couldn’t grow a flower if you tried but would be excellent at water gardening. If you are looking for a way to occupy some time or to beautify your yard, water gardening is an excellent way.

Pest control in the perennial garden


One of the many advantages of growing perennials is the ability of these beautiful flowers to return to full bloom season after season. While this ability to bloom repeatedly is one of the things that makes perennials so special, it also introduces a number of important factors into your gardening plan. One of the most important of these is a proper pest control regimen.

While a garden full of annuals starts each season as a blank slate, the perennial garden is essentially a work in progress. The fact that the plants stay in the ground through winter makes things like proper pruning, disease management and pest control very important. If the garden bed is not prepared properly after the current growing season, chances are the quality of the blooms will suffer when the next season rolls around.

One of the most important factors to a successful perennial pest control regimen is the attention and vigilance of the gardener. As the gardener, you are in the best position to notice any changes in the garden, such as spots on the leaves, holes in the leaves, or damage to the stems. Any one of these could indicate a problem such as pest infestation or a disease outbreak.

It is important to nip any such problem in the bud, since a disease outbreak or pest infestation can easily spread to take over an entire garden. Fortunately for the gardener, there are a number of effective methods for controlling both common pests and frequently seen plant diseases.

Some of these methods are chemical in nature, such as insecticides and fungicides, while others are more natural, like using beneficial insects to control harmful ones. While both approaches have their advantages and disadvantages, many gardeners prefer to try the natural approach first, both for the health of the garden and the environment.

There is an additional benefit of the natural approach that many gardeners are unaware of. These days, it is very popular to combine a koi pond with a garden, for a soothing, relaxing environment. If you do plan to incorporate some type of fish pond into your garden landscape, it is critical to avoid using any type of insecticide or fungicide near the pond, since it could seep into the water and poison the fish. Fish are extremely sensitive to chemicals in the environment, especially with a closed environment like a pond.

As with any health issue, for people or plants, prevention is the best strategy to disease control and pest control alike. The best defense for the gardener is to grow a garden full of the healthiest, most vigorous plants possible. Whenever possible, varieties of plants bred to be disease or pest resistant should be used. There are a number of perennials that, through selective breeding, are quite resistant to the most common plant diseases, so it is a good idea to seek them out.

Five Tips to Maintain a Healthy Lawn while Landscaping

Landscaping your home can be an exciting and invigorating experience, particularly if you plan to do the work yourself. There is something that can get lost in this process though – a healthy lawn. To often your grass pays a price when your attention gets diverted to other sections of your garden. Here are a few suggestions of ways to prevent your lawn from suffering while working on your new landscaping projects.

1. Proper planning

You will probably spend a lot of time planning the landscaping of your new garden. Don’t forget about your grass when planning your new layout! While water features and plants are more exciting than the location and shape of grass, it is these green areas that will give your garden its unity and allow you the space to enjoy your new creation. Grass many seem a secondary consideration, but proper planning ahead of time can save a lot of stress on your grass in terms of cutting and moving.

2. Be Aware of Wear and Tear

Landscaping often involves a lot of moving of soil and stones and plants so you want to think ahead and consider what spots on your grass will receive the most traffic. Some grasses stand up to wear and tear better than others so you need to figure out what type of grass you have and how it might fair. Try to reduce the stress on your grass by limiting the amount of traffic that goes across it. You could even lay down boards on the spots that you anticipate the most traffic going through. This may mush up your grass a bit, but will protect it from any major damage. If you do lay down boards, you’ll want to make sure that you list them up for mowing and watering so your grass gets all of the care it needs.

3. Continue Your Usual Maintenance

After spending hours in your garden landscaping, the last thing you probably want to do is cut the grass. It is important that you be consistent in your maintenance throughout the landscaping process. By staying on top of things like length and weeds, you may save yourself valuable time later on. Though it may be the last thing you want to do after a long day slaving away in the garden, your grass still needs the usual maintenance.

4. Try a Little TLC

If you do neglect your grass while working on your landscaping project, then be sure to give it lots of TLC when the project is over with. Grass that has been ignored can often be brought back to it original state with a little care and attention. You’ll need to be consistent with your mowing and watering and you might also need to apply fertilizer depending on the state of your grass and the time of the year. You’ll also need to address any weed problems that have crept up while your attention was focused elsewhere. If you have neglected your grass to the point that it has brown spots, then you will need to try to bring that grass back to life through a lot of watering. You can also apply sugar to these brown spots to get the microbes active again. If the damage is too extensive, then try encouraging new growth by spreading grass seed. You can lay new sod if there is no chance for your grass after the landscaping process is over.

5. Water, Water Everywhere

Water can work wonders on neglected grass. When working on your landscaping project, be sure that you are giving your new plants enough water, but don’t forget about your grass. Consistent watering can often revive grass that has long been neglected in favor of other gardening projects. Grass that has lost its lush texture and rich color can be revitalized simply through watering in many cases. Watering while the grass is under the stress of landscaping can also really be beneficial.

By ensuring that your grass is getting the nutrients and moisture that it needs, you’ll be saving yourself a lot of time in the long run and guaranteeing that your newly landscaped garden looks perfect right down to each blade of grass.
