This has been a strange season. My garden is in the highlands of western Pa. So the growing season is more like New England.
Usually I get a dense jungle of foliage from tomatoes. This year my plants are so spindly it looks more like June than mid-August. They are fruiting their little hearts out, but much if the yield is sun-scalded. I notice that others' tomatoes in the neighborhood are just as spindly as mine.
I use black plastic mulch to stretch the season and to conserve water. Cukes, herbs, corn and dahlias in the same garden have prospered. There is no recognizable disease on the plants. So what happened to my tomatoes this year.
