Avocado Tree Transplant Shock: Browning Leaves, Sunburn, and Fertilizing

Helping a Young Avocado Adjust to Outdoor Life in Florida

Moving a 3-foot avocado from pot to ground in Jensen Beach (Zone 10a) caused tip burn and lower-leaf browning—classic transplant shock and insufficient hardening off.

What’s Happening

• Lower leaf drop – normal; the tree sheds old leaves as it establishes roots.
• Tip burn / sunburn – caused by sudden exposure to intense Florida sun without a 7–10 day shade acclimation.
• New growth – excellent sign; the tree is recovering.

Actions

• Do not remove browning leaves; they’ll fall naturally.
• Provide temporary shade cloth if sun is intense.
• Water deeply 2×/week; mulch 3 inches with straw.
• Hold off on fertilizer until spring; then use organic fruit-tree fertilizer.
