Let me just add a couple of comments. Our tuberoses don't get sun until nearly noon, and are usually in shade by 3-4 p.m. The ones on the west side of the garden seem to do better since they get the sun first and also the first shade. We do mulch our tuberoses and the mulch stays on year round ( we use pine needles). If growing tuberoses in the ground, mulch them and see if that will keep them from dying. So much of gardening is trial and error, guess we all know about that.
