Fertilizing Hemlocks After Winterburn: Balancing Acidifiers and Complete Fertilizer

Assess the Damage

Winterburn on newly planted hemlocks is common. The priority is root recovery, not heavy fertilization.

Hollytone: Acidifies soil but doesn't provide balanced nutrition. Overapplication burns roots.
10-10-10: Apply 1 lb per inch of trunk diameter, spread under drip line (not within 1 ft of trunk). Water in well.
Mulch with pine straw: Gradually acidifies soil and conserves moisture.

Fertilize in early spring and late fall. Avoid summer applications that stimulate tender growth before winter.
