Can anyone tell me what is wrong with my cherry tomato plant? I bought it several months ago and planted it in in a large pot and it went very well at first - it grew very quickly and had lots of flowers. Then all of a sudden all the leaves started going yellow and wilting (as you can see in the picture). However, the plant is still alive. Even though the leaves around them appeared dead, the flowers still produced plenty of fruit (although they seem a little sort of dried out and cracked), and I still have new leaves growing at the ends of the branches with new flowers! I have Googled diseases but nothing seems to quite match my plant. Is there anything I can do for it?
