Fruit Tree Fertilizer: Low Nitrogen, High P-K, Early Spring Application

Reader Question: What Fertilizer for Fruit Trees and When?

"What kind of fertilizer for fruit trees and best time to apply?"

Expert Answer: Target Root Development and Fruiting, Not Leaf Growth

• Analysis: 0-10-10, 5-10-10, or 10-20-20 (low N, higher P & K).
• Timing: Early spring as growth starts.
• Method: Spread pellets in circles from a few inches off trunk to drip line. Incorporate lightly with hoe/dribble or apply under mulch.
• Water well after application.

Excess nitrogen = vegetative growth at expense of fruit. If tree is in a fertilized lawn, use 0-10-10 to avoid extra N.
