I have one plant that the leaves are really curling up and in. A couple of the other plants have a little bit of curling but nothing like this. The temps here(desert southwest) have been in the low 100's for a few days. Any suggestions would be greatly appreciated 20160624_095759 by jb61553 posted Jun 25, 2016 at 12:12 AM .
Either your under watering them or the temps are too high/no wind to cool the plants. I recommend you water as soon as possible and mist the leaves early morning and late evening until they begin repairing themselves.
After beating my head against the wall for several weeks I think I finally found the problem. Russet Mites. Just got through spraying my plants with NEEM. Hope like hell I can salvage a couple of them.
It might work somewhat but recently Neem wasnt qorking for me so I resorted to insecticide for roses, its like a white powder you put on the plants leaves and usually geta off the plant within a week and when bugs get in contact with the powder on the leaves they die or go away.
