Similarly, what is the best fertilizer for Norway spruce trees?
Fertilizers for Spruce Spruce trees do not have very high phosphorous needs and benefit most form an acidic fertilizer designed for evergreens or a high-nitrogen fertilizer with a formula like 12-6-4 or 10-8-6. Organic fertilizer options include compost, fish emulsion, cottonseed meal and alfalfa meal.
Just so, what is the best fertilizer for evergreen trees?
A “complete” fertilizer — one that supplies the macronutrients nitrogen (N), phosphorus (P), and potassium (K) — is often recommended. A fertilizer analysis of 10-8-15 means the fertilizer has 10 percent nitrogen, 8 percent phosphorous, and 15 percent potassium.
