Alas, we’re officially on the downside and downslide of summer when the inevitable powdery mildew shows up on the squash and cucumbers. The ‘Buttercup’ winter squash is the hardest hit, since it was shaded more as it wound its vines beneath the corn, so with the corn completely picked it was time to remove some stalks to let more light in for the squash and increase air circulation.
Although commercial growers may apply chemicals to retard the formation of mildew, it really is a natural phenomenon that ties in with a change in season, via changes in temperature and humidity.
In town I’ve spotted a slight color tinge to some vine maples, and other plants are exhibiting their seasonal “green fatigue”. Given the lower sun angle and record low temperatures of 41 during the last week, it may be time to use plastic over the tomatoes, at least at night. After another interlude of partly overcast days, we’re due to warm up to the mid-upper 80’s for a stretch, but the heat won’t be the same.
Meanwhile, a new group a ‘Rainbow’ Swiss chard is sprouting well, along with a row of lettuce.
Stay tuned for the end-of-month tally next week……
