Things are moving quickly in the two community teaching gardens. In the past week or so we’ve gotten a good amount of rain, warm weather, and ample sunshine. Many of our heat-loving plants which were lagging behind are now taking off. This week in the advanced course, we did a review of harmful and beneficial insects, worked with our compost and planted our sweet potatoes. The beginner gardener class welcomed their first guest teacher of the season, Vic Izzo, an entomologist who works with growers in the area.
This season, the advanced class has been especially focused on producing viable compost to restore our garden at the end of the growing season. We visit our compost bin each week to assess the quality of the compost we are creating, and to vigorously turn the compost by transferring it from one bin to the next. In the process, we take a multi-sensory approach to examining our compost: looking for beneficial insects, smelling for positive or negative signs of decomposition, and feeling for heat. Students are encouraged to bring plant-based food scraps from their homes to add into the mix we have created of scraps, straw, and already prepared compost. This week, we added nitrogen-rich comfrey from our garden to increase decomposition rates.
On Thursday night, Vic Izzo joined the beginner gardeners at the Ethan Allen Homestead. His hands-on lesson focused on two common pests in Vermont, the Colorado potato beetle and the leek moth. During his visit, students learned how to identify these pests and the damage they cause in the garden. Potatoes and eggplant are susceptible to Colorado potato beetle, while onions, leeks, and garlic are attacked by leek moth. Vic suggested strategies for managing these pests using integrated pest management. Specially, he suggested monitoring the flights of leek moths and covering your garlic and other attractive crops while leek moths are in their larval stage. When it comes to Colorado potato beetles, the most affective approach is often removing the beetles by hand and crushing their eggs before they hatch.
Students will continue to implement these strategies and more as new pests appear in the garden. We look forward to sharing what we learn with you!
