Practical Garden Pest Management

Insects are a fact of life in the garden and that's not a bad thing. Many plants depend on insects for pollination after all. There are many ways that insects can be beneficial partners for us, in the garden. There are also insects who do a lot of damage to flowers and vegetables. It's up to the gardener to try and strike a balance.

    The first step in garden insect management is to be aware of who is there and what they're doing. Even some of the so called "pests" are only having a snack as they pass through your garden. You wouldn't want to bring out the spray can to get rid of a monarch butterfly caterpillar who is munching on your parsley. Integrated Pest Management (IPM) is an approach toward insect control that walks the line between catching problems before they escalate and how much damage can you...MORE handle before you bring out the heavy artillery. If you can create a type of harmony in your garden, it's good for you, your plants, and the environment.

    Integrated Pest Management goes beyond monitoring for pest insects. There are steps you can take to make you garden less inviting to those pests and it doesn't take a lot of effort or money. Tweak the cultural conditions of your garden and cut down on future work and problems.

    I mentioned that not all insects are out to wreak havoc on your garden. Some go beyond pollinating in their beneficial impact. There are insects who prey on some of those infuriating pests, like aphids and cabage worms. These are the insects we want to encourage to feel at home in our gardens and all it takes is knowing which plants they are attracted to and giving them cover in the garden.

    To keep the peace in the garden, you have to know what your dealing with and that starts with identifying what is causing the problem. It's not uncommon to mistake a disease for insect damage or the other way around and no amount of pesticide is going to cure a fungal disease. Here are photos of some common insect pests and the kind of damage they do, along with some possible controls.

    Controlling Aphids

    I don't know how they do it, but some insect pests find their way into your home and onto your houseplants. (How do they know there are plants inside?) Indoor pests can be even harder to control than garden pests because there are no natural predators indoors - or at least not many. The pests profiled here tend to hide under leaves unnoticed until the problem is extensive. Check for them every time you water, to stay on top of the situation.

    Even if your precious plants are being devoured by marauding pests, you don't have to spray toxic chemicals with abandon. There are less toxic options. Do yourself and your plants a favor by always starting with the least toxic solution first. If you can catch the problem early, that's all you should need.

    Thank goodness for the internet. We now have access to thousands of pages of research and recommendations for just about everything. I always refer people to their local cooperative extension office, because they know what problems are affecting your area and what the best options are for controlling it. Most have Master Gardeners who will answer your questions via phone and they all have web sites with frequently asked questions. Here are a few of my favorite go to sites for answers to my...MORE garden problems - and yes, I do have some.
