Pineapple Guava Leaf Tip Burn: Water, Fertilizer, and pH

Pineapple Guava Leaf Tip Burn: Water, Fertilizer, and pH

Brown leaf tips and drop on a newly planted pineapple guava in zone 9b suggest establishment stress: insufficient water for root development, fertilizer burn (high salts), or soil pH imbalance. The plant prefers acidic, well-drained soil and is drought-tolerant once established.

Corrective Steps

• Water deeply 2-3 times weekly for the first few months; then reduce.
• Stop fertilizing; flush soil with water if salt buildup suspected.
• Test soil pH; amend with sulfur if above 6.5.
• Mulch with pine bark to maintain acidity and moisture.

Pale leaf spots may be minor fungal; they often resolve with improved culture.
