Leaf scorch
Script error: No such module "For".Script error: No such module "Redirect-distinguish". Script error: No such module "Unsubst". Leaf scorch (also called leaf burn, leaf wilt, and sun scorch) is 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.[1]
Causes
Leaf scorch can be caused by soil compaction,[1] transplant shock,[1] nutrient deficiency,[1] nutrient excess, drought,[1] salt toxicity,[1] herbicide injury,[1] and disease injury.[2][3][4]
Treatment
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.[5]
In the case of leaf scorch through over-fertilization, recovery may take time, requiring a treatment of a slow leaching process through drip irrigation over 24–48 hours.[5][6]
Prevention
Reversal of symptoms and damage can be enacted through the following cultural practices:[1]
- Pruning sprouts and affected areas
- Avoiding frequent, light waterings which promote unhealthy root systems
- Watering heavily to promote deep root systems
- Avoiding over-fertilization
