Frequently Asked Questions (FAQs)
1. What is the best fertilizer for trees?
As a result, trees usually respond best to fertilizer with a 2-1-1 or a 3-1-1 ratio (nitrogen-phosphorus-potassium). Commonly available fertilizers with a 2-1-1 or similar ratio are 18-6-12, 12-6-6, 10-6-4, 10-8-6 and 10-8-4.
2. How often fertilize trees and shrubs?
Fertilizing twice a year is preferable to the common practice of fertilizing every two to three years. The best time to fertilize is fall, generally after the first hard freeze in September or October. The next best time would be before growth begins in early spring, usually between March and early May.
3. Do trees and shrubs need fertilizer?
In nature, shrubs and trees survive without fertilizers because they're growing in undisturbed soil and receive nutrients through the recycling of organic materials, such as fallen leaves, that decompose and release their nutrients to the plants.
4. What's the best fertilizer for evergreen shrubs?
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.
