Protecting Your Landscape from Insects
from: Lawn and Garden MagicInsects can cause significant damage to your landscape, and this can result in costs to treat the damage or replace damaged plants. Managing insect pests is a very important part of landscape maintenance that requires you to take an active role in protecting your plants and caring for them. It's important that you know what youa'e dealing with beforehand to ensure that youa'e adequately prepared to combat insect pests, whether you use natural methods or synthetic methods.
One thing you should 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's possible to treat most insects with pesticides, but it's 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 because healthy plants are more resistant to the vagaries of insect pests and they'll stand up to harsh measures if they have to be taken.
Here are some general guidelines to help you have the healthiest possible plants and to help your landscape increase its defense against insects:
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 ensure that even if one particular plant is ravaged, 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'll 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 doesn't have time to strengthen and take root. By doing this 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 isn't severe, it's possible to take no action against them, but this does carry 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, be sure to use these 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 because too much insecticide can cause damage to your health, as well as to the health of your plants.
