I live in FL in zone 9a or 8b. I have 2 bald cypress that I bought the winter before last. I got them in the ground and watered them like crazy. I water them very often (every 2-3 days) leaving the hose on them for hours at a time. In the spring they bloom with lots of leaves but now in about mid June I am seeing the leaves turn a rusty color. It doesn't start at the tip of the leaf but at the base and works its way out until it dies (see pics) Last year both trees did it at the same time. This year I only notice one doing it. All the other cypress I see in my area are lush and thriving right now. Any insight would be greatly appreciated.
