Jon shows us how to deal with Mexican Bean beetle pests on a mature crop of beans. Learn more about this pest on the HGIC website.
A few weeks ago you were sitting back admiring your freshly planted garden. Neat little rows of tomato, pepper, squash, and cucumber plants accompanied by flowers and herbs were all planted in view from your back deck. As you sat there basking in the evening sun, relishing in your hard work, a little moth fluttered from flower to flower sipping nectar.
With her hummingbird like flutters, a Carolina Sphinx Moth floated through your garden, unassumingly laying her eggs on your newly planted tomato and pepper plants. Within a few days, from her little green eggs emerged a tiny but very hungry green caterpillar.
Since that day, the ravenous little green hornworm caterpillar has spent his days munching away, perfectly hidden by the copious green foliage of your tomato plants, growing bigger and bigger. You begin to notice stems of complete defoliation. Maybe you think it’s a bunny or deer having a nighttime nibble as the little green caterpillar stays camouflaged, until the moment you notice the red-tipped horn and the very large green body of a caterpillar measuring almost 4” in length hanging on your prize winning tomato plant.

I recently went to the International Master Gardener Conference in the Philadelphia suburbs. A fun part of these conferences is the tours and learning sessions in various public gardens, and that part of Pennsylvania certainly doesn’t lack gardens! (Many generous wealthy people donating estates = lots of places to play with plants.) On my last day there, I went on a tour of Fordhook Farm in Doylestown, the home of the Burpee company. We were welcomed by George Ball himself (looking dapper in a white suit) and given a lecture about the history of the company. Then we were set loose to tour the trial gardens. Of course I headed straight for the vegetables. Read More
Spotted lanternfly adults may be found feeding on many hosts, especially tree of heaven (Ailanthus altissma). Report any finds to the Maryland Department of Agriculture immediately, collect a sample or take digital photos of what you have found.
Bagworm caterpillars are now very active. Look for little bags crawling around on evergreen trees and shrubs and be prepared to spray infested trees with the microbial insecticide, Bt by mid-July. Mature bagworms are not well controlled with Bt They are best collected by hand and destroyed or sprayed with insecticides containing spinosad.
Proper lawn mowing is critical to help it survive the summer. “Mow ‘em high and let ‘em lie” should be your mowing strategy. Cut your cool-season turf (fescues and bluegrass) to a height of 3-4 inches and leave the clippings on the lawn where they will naturally decompose.
Sow seed for fall transplants of broccoli, kale, turnip, and cauliflower in flats or containers by the 3rd to 4th week in July. Late crops of squash, beans, and cucumbers can be direct sown into your garden through the end of July.
