Answer: If the leaves are crispy brown, sunscald or heat stress is probably the cause; if the leaves are still pliable but brown, a fungal disease might be the cause. Root rot from poorly draining soils can cause the same symptoms. I'd try pruning the plant back to get rid of the browning foliage and also to encourage healthy new growth. If the roots are okay, your plant will green up. If the roots are affected, it won't put out new growth. Pruning will also open your plant up to better air circulation, which will help it fend off diseases. Hope your plant recovers!
