Plants require three major nutrients: nitrogen (N), phosphorus (P), and potassium (K).
- Nitrogen fuels leaf and stem growth and is the nutrient that depletes fastest (especially in lawns).
- Phosphorus stimulates root growth and seed formation and is prominent in fertilizers used in fall.
- Potassium promotes flowering, fruiting, and disease resistance.
Follow this advice whenever you use fertilizers.
- Avoid overuse of fertilizers.
- Water plants and lawns well before using water-soluble products.
- Delay fertilizing newly planted trees and shrubs for a year.
- Do not fertilize plants stressed by drought.
- Do not fertilize and lime the lawn simultaneously.
