Datura

I have a Datura which has flowered very well but the leaves constantly turn yellow. I have fed it tomato fertilizer and epsom salts . please can you help?

Ours do the same, and have for three or four years, so they aren't on the way out. Feed, feed, feed and an "incontinent" supply of water was the advice we got. Occasionally when there are more yellow than new green leaves, I feed with high N lawn fertiliser, which gives the new leaves a boost. Do you overwinter it?

Thanks for the advice. I will try it. I do overwinter in the green house and normlly cut it down to about 9" but don't water it very much in the winter.
