We put up two little greenhouses for the tomatoes this year. We’ve given them plenty of food and water. It’s a bit shady, not the usual place we put them, and they have grown leafy, but with very few flowers, and they don’t seem to have set. It’s getting too late for tomatoes now. On the other hand the local shop gave us some very withered and dried up small tomato plants yesterday but they have fruit growing on them. Weird… Anyway I guess I’m lucky we had other produce xxx

Common problems with bloom setting tomato’s.
Tomato’s are not very shade tolerant. Tomato’s like full sun growing conditions.
Blossom drop will occur if daytime temperatures are warm but night temps drop below 55 F. (13 C.).
In the summer when temperatures go above 90 F. (32 C.) with nights over 76 F. (24 C.); again, the tomato plant will suffer damage to immature fruit or loss of blooms.

Useful info. It’s the shade I think that’s causing the problem.
