I transplanted tomato plants from the garden into pots and they have been growing in my greenhouse. I noticed their leaves are turning purple. Does anyone know what is happening? Up to this point they have bloomed and I have a few small tomatos. I was planning on put them back in the garden hopefully next month. I can't decide if I have watered too much or not enough. It has been cloudy for about a week so maybe not enough sun. Help
Phosphorus deficiency, which tends to occur when the soil temps are too cool. SB
Any suggestions? If it is sunny tomorrow should I bring them out?
Sure, if it would warm the soil. I would also apply a fert higher in phosphorus. SB
when u say you transplanted from the garden..when...last fall?
Yes right before the first frost.
Just an update on the tomatoes. I used a hibiscus fertilizer that someone on this website had talked about and have put the pots outside. The purple leaves are turning green again and looking good.
