The tops of a few of my lilies look like something's wrong. Some look okay, but a few look like this one--it's just the top, new leaves.
We've had rain followed by hot sun that's hot enough to wilt almost all my plants. They do perk up in the evening or if I give them a small drink of cool water. Could this be the result of the sun burning the leaves due to magnification through water? Or is the soil deficient in something they need to stay green?
I'm in zone 5b.
Thanks in advance.
