Hunger! Or lack of water.

could be the variety or if it is a young plant that will be why.

Good feed with Blood, Fish and Bone, Growmore or good rotted horse manure followed by a heavy mulch and as Owd says plenty of water.

Thanks all, will do as you suggest.

Sympathy Hank. I went to get some for lunch today and it was drooping and sad. It must be the dry weather. n everf seen this happen before.
