mine have been erratic, they started off well but with the heat in July they stopped but I just left them alone and the last 2 weeks they have been very good, though short stemmed.

the rain certainly marks the petals but they usually send more buds up. have you been dead heading them. if seeds are left to form then they tend to stop flowering.

Have you been using fertiliser?

Pick them every couple of days when flowering. Very few go to seed. Don’t use any fertiliser. I’ve enjoyed terrific crops in the same spot for about 15 years. First year to have a problem. The only thing I can think of is perhaps the actual plants which were from a different source and variety. Will stick to the old favourites next year in the hope of a better crop. Thanks for the comments.
