rose leaves are curling. why???
i have 3 spectra's that are new to me this year as bands, all in the ground and doing very well. i watered them 2 days ago and they were fine. i went to water tonight and one of them has leaves that are curling upward and inward, if that makes sense. i examined this rose very, very closely..there are no signs of any insect anywhere, just the curling leaves..both old and new leaves.the leaves are still green, no sign of yellowing or browning...i might add that the spectra with the curling leaves actually touches another rose, and the other rose, iceberg, is unaffected..so far. we have also been having a heat wave here, with temps in the high 80's..don't laugh..for us..that's a heat wave!!any ideas??? thank you...donna
