Cucumbers are still producing but they’ve developed powdery mildew on their leaves. Best guess is that the leaves have been too wet too often this summer which can be a problem especially at night. The Library has a sprinkler system that is set to go on every night and the cucumbers are fairly close to one of the sprinkler heads. This, plus cooler temperatures in general, plus the heavy rains we have experienced lately have all been contributing factors.

The plants have been enjoying some fresh air and sunshine. And they have also been experiencing some cool (under 50 degrees) nighttime temperatures and some elevated wind conditions. They are almost hardened off completely and we are planning to plant them out next week. Today is the first day they were in the sun for most of the day.
