I have a small tomato plant which self set in my garden and has produced a few tomatoes - I transplanted it into a pot and fed it now and again. The plant is in perfect condition right now sitting on my kitchen window sill, with green tomatoes and many flowers. What should I do with it? Are the fruits likely to ripen?
Tomatoes require lots of direct sun and heat. If you can reproduce summer conditions inside, you may have some luck. Natural light at this time of year is insufficient.
