Plant Nutrient Guide: Primary & Micronutrients, Timing & Application

17+ essential nutrients. Three primary (N-P-K) on every fertilizer label. Micronutrients needed in trace amounts—premium blends include them.

When & How to Fertilize

• Young/fast-growing: every 1–2 weeks with soluble feed.
• Established trees/shrubs: 2–3× spring to early summer.
• Dry fertilizer: spread evenly at drip line, water in. Spring application.
• Slow-release: follow label exactly.

Critical Rules

• Water thoroughly day before fertilizing—never feed dry plants.
• Irrigate between applications.
• Less more often > heavy once. Excess burns roots, kills plants.
• Test soil first. Deficiencies hard to diagnose; prevention wins.
