Leaf scorch (also called leaf burn, leaf wilt, and sun scorch) is defined as a browning of plant tissues, including leaf margins and tips, and yellowing or darkening of veins which may lead to eventual wilting and abscission of the leaf.
Affected plants may sometimes recover through watering and fertilization (if the cause is not over-fertilization). Light pruning may also help to reduce the water-pumping load on the roots and xylem.
Reversal of symptoms and damage can be enacted through the following cultural practices:
- Pruning sprouts and affected areas
- Avoiding frequent, light waterings which promote unhealthy root systems
- Watering heavily to promote deep root systems
- Avoiding over-fertilization
