Some of the crops harvested from our green roof and green wall
Zucchinis take a lot of space and grow large leaves very quickly. These plants boomed before all others, covering over some eggplants, beets and edaname. We have been eating these for more than a month now. Since they grew so big we grilled most of them.
The cucumbers grew a little slower but now are producing a lot of fruit.
From the Wall Farm green wall system we harvested Onions, Garlic, Potatoes, and Red Chard
Green roof gardening is not without pests. First appearing were vine borers in the zucchini’s. Since they grow inside the stems of the plant they are hard to detect until a lot of damage is done. When I noticed lesions in the stem at the base of the plant, I cut open the stem lengthwise and could dig out these vine boring worms. I then made more cuts in other ares of the stems and dug out more worms and eggs. I then spray neem oil directly into the stem openings. This has ridded the zucchinis of the vine borers in one treatment. After removing all yellowed leaves and diseased fruit form the invasive cutting and digging, they quickly recovered.
Another invader that has recently arrived is the Harlequin Bug (Murgantia Histrionica). Also known as Calico Bug or Fire Bug. It is a member of the Stink Bug family, usually Black with Orange, Bright Red or Yellow markings and about 3/8″ long
We spent a day hand picking these leaf sucking bugs off our Bok Choy plants and Broccoli Plants. They infected the Bok Choy more aggressively than other plants. We should have taken action earlier since there are a lot of yellow Bok Choy leaves.
We picked off all the bugs we could see, lifting up leaves to reveal the bug’s resting places. We also picked off all the egg clusters. Many of the adult bugs were mating. Most adults did not move too fast and are easy to catch. The smaller younger Harlequin bugs fly away very fast and could not be captured. Once caught the bugs were dropped in a cup of soapy water to kill them. Around one hundred were caught.
We have been enjoying Bok Choy from this patch all summer long. We now have removed all infected leaves and see fresh sprouts at the center of the plants, so we expect the Bok Choy plants to recover and produce more of the delicious vegetable.
