Why do my tomato plants grow tall without producing flowers?
Oxfordshire, United Kingdom
I have a south facing cold greenhouse, however it does have trees to either side. I live in South Oxfordshire.
Over the years I have grown different varieties together in the greenhouse and always grow them from seed in a propagator - usually in normal potting compost. The seeds are started off in my conservatory.
I used to start them off in March/ April to plant out in early May and found the plants grew tall in the propagator and this continued when I planted them out (I use the ring culture method).
The result was the tomatoes grew by more than 2 feet even before the first flowers appeared so the plants were at the greenhouse roof before even 4 trusses were produced.
This year I delayed the planting out until mid June when we had pretty good and warm weather but the situation as been even worse with the plants shot up even more such that I have only two lots of flowers.
My mum had a greenhouse which was very shaded and she never seemed to have this problem. (She grew the plants in grow bags but did buy the plants from a wholesaler)
What am I doing wrong?
