Fertilizing Hemlocks: Miracid at Half Strength for Acid-Loving Conifers

Hello Keith,

Hemlocks (Tsuga) prefer acidic to slightly alkaline soil. Start with a half-strength solution of Miracid (or any fertilizer for acid-loving plants). If foliage yellows over time, gradually increase concentration until color improves. Avoid full-strength applications initially—conifers are sensitive to salt buildup.

Apply in early spring and again in early summer; cease feeding by midsummer to allow hardening before winter.
