As in previous years I grew my tomatoes from seed. I have used gardeners delight and country taste. For some reason all my plants put on about 4'-5' of growth before producing flowers. This has meant that they are only just at the flowering stage with a few small tomatoes and I doubt that I will get any kind of crop this year. I have some in a porch, some in a shed, some in pots outside and some in the ground. All have the same growth habit. What is so annoying is that a few left over plants I gave to my sister have grown in the usual way and she has a nice crop on each plant.
Can anyone throw any light on what has happened to my plants this year? It is the first time in over 40yrs I have had a problem.
