Winter Tree Fertilizing: Why It's Actually a Good Idea

Tree company wants to fertilize in winter with 30-7-9? If trees haven't been fed recently, winter application works well.

Why Winter Works

• Tree roots spread far beyond dripline—wide nutrient capture zone.
• Winter rain moves nutrients into soil profile.
• Nutrients disperse in all directions before spring growth.
• 30-7-9 = 4-1-1 ratio—excellent for trees.

Follow-Up

Arborist should evaluate shoot growth response next season to determine if additional feeding is needed.
