Where there are plants there are caterpillars. As an avid gardener, you are probably familiar with several species of caterpillars, particularly those that damage some of your favorite plants, such as tobacco hornworms, cabbage loopers, and tomato fruitworms. But our gardens and landscapes are host to hundreds of other caterpillar species.   >> read article

Often when pulling weeds or mowing the grass, my mind drifts to some of the challenges in the world. I don’t mean solving world hunger or anything, but just considering some of those gardening questions not discussed on radio shows. This happens in a “stream of consciousness” where one thought or question runs into another and another and so on.   >> read article

When most people think of wasps, they think of paper wasps, and they probably think of them only as pests because of unpleasant past encounters with these stinging insects. However, the world of wasps is much larger and more complex than this! Our gardens abound with hundreds of species of wasps that vary greatly in size and life habits. Most of the wasps in our gardens are tiny, parasitic species that do not sting people and go largely unnoticed. These are definitely friends because they help control pest insects. There is also a group of wasps known as sawflies whose larvae look like caterpillars and feed on plants. These are usually foes because they damage landscape plants. Two other groups of wasps are the social wasps, such as paper wasps, and the solitary wasps, such as mud daubers and cicada killers. Wasps in both these groups are capable of stinging, and they definitely qualify as foes when they do so, but paper wasps also have a beneficial side.   >> read article

Gardeners take pride in the appearance of their landscapes. However, nothing detracts from the beauty of flowerbeds like weeds. Along with being aesthetically displeasing, weeds in flowerbeds compete with desirable plants for water, nutrients and light. If weeds are out of control, expect fewer flowers and more headaches. For most people, backbreaking hand removal is relied upon exclusively to remove weed problems. Hand pulling may be successful for a few weeds, but for most weed problems it is only partially effective.   >> read article

Every gardener has experienced it, usually more times than they can count. You walk into the garden and discover a plant that’s been defoliated or otherwise damaged by caterpillars. The canna leaves are riddled with holes, the cabbage leaves look like lace, half the tomatoes have worms in the fruit, or the azaleas have been stripped of their leaves. How could this happen so quickly?   >> read article

The term “canker” refers to a lesion on a twig, branch or stem, usually caused by a bacterial or fungal pathogen. The appearance of cankers varies, depending on the host and the pathogen. Often, the bark of the affected stem or trunk is sunken and discolored. Fluids may ooze from a canker or fungal fruiting structures may appear on the bark covering or surrounding the lesion. In some cases, lesions remain small and isolated, causing no major problems for the host plant. In other cases, the canker spreads widely, causing death of twigs, branches or even the main trunks of trees. The best known example of the destructive potential of a canker disease is chestnut blight, caused by the fungus Endothia parasitica, which caused the virtual extinction of the American chestnut within 40 years of its accidental introduction to the United States in about 1900.   >> read article

Integrated pest management or IPM is a smart way of managing insect pests for economic and environmental benefits. IPM starts with the timely detection and correct identification of pests, leading to intervention using multiple control tactics. Insect traps can be used as a tool for timely pest detection and decision-making in home or commercial settings.   >> read article

If you have a garden, it’s more than likely that you also have a pest or three. It should be no surprise that pests and critters like our yards and gardens as much, or more, than we do. We are encouraged to invite wildlife into our yards and gardens because we love seeing them, and, in theory, they help balance our desire for our garden and nature to coexist. But what happens when they go rogue and start eating, digging and destroying all of our hard work?

Scaring them away, or we could say gently discouraging, wild and sometimes not-so-wild critters to “Step away from the garden,” is always a first and sometimes successful option.   >> read article
