Fall Garden & Landscape Pests
While most pests start to dwindle in the fall, others can plague your autumn garden and landscape.
Gardeners might be tempted to rest on their laurels by the time fall comes around, but that may not be the best idea. While many pests are dwindling in numbers thanks to dipping temperatures and others are beginning to contemplate hibernation, there are still some pests that can plague your autumn garden and landscape. Here are the ones to look out for—and what to do if you find them.
Aphids like it hot, but they can plague your fall garden if the temperatures remain warm through much of September and into the early weeks of autumn. These tiny insects have pear-shaped bodies and long mouths used to pierce plant foliage and suck out the juices. Their sugary secretions often cause sooty mold that can further harm your plants. It's not uncommon for aphids to affect nearly every plant in the garden. If you only see a few, you can first try to dislodge them with blasts of hose water. However, to combat a big aphid problem on your vegetables, flowers, or other ornamental plants, use Ortho® Insect, Mite & Disease 3-in-1 Ready To Use.
Slugs & Snails
During the fall, slugs and snails can lay over half of their eggs, each of which will hatch in 2-3 weeks. These young slugs and snails will then overwinter in your garden and start to feed in early spring, when the temperatures warm. Though they may look like they’re slow, slugs and snails can destroy seedlings and other plants (like your favorite hosta) virtually overnight. If you notice large holes in your plant leaves, suspect slugs and snails, especially if you spy their "slime trails" on the surfaces of the plants. Using Ortho® Bug-Geta® Snail & Slug Killer2 is an effective way to control a slug or snail problem quickly. It can also be used around pets and wildlife.
