I did some rearranging today. I moved the small greenhouses and put all, but one, of the tomatoes in the green one, and the last one together with pepper plants, fennel and a poorly looking strawberry plant, in a black one. I thought moving all the tomatoes to a sunnier spot, with protection from wind and rain, would perhaps help them produce tomatoes... And, when I was putting the tomatoes together I saw that one plant had got one small green tomato! My first this year! :) Sadly the cauliflower and brussel sprouts have got vermin... I got the advice to throw away those plants who are infected, and I will try and spray the ones left with soap water. Fingers crossed!
