I thought the day would never come! We have had these plum tomato plants for months now and while they have actualy grown quite a bit over the last couple of weeks it is only now that I have spotted the first flower. So we might have tomatoes after all. The last week it has been very hot (heatwave warnings have been given, although if you ask me it is just summer!) and so each night the plants have had a good soaking. I would think this mixture has been just what the tomato plants have wanted.
