How to Fertilize perennial phlox?
For optimal growth, garden phlox benefits from balanced nutrition fertilizers, shifting to high phosphorus formulas pre-bloom to enhance flowering. Apply granular fertilizer sparingly in early spring as new growth appears, and again during early blooming. A liquid feed monthly supports ongoing vigor, especially in poor soil. Too much fertilizer can spur leggy growth, while insufficient fertilization may lead to weak blooms. Seasonal changes dictate adjustments; decrease application in late fall and avoid winter fertilization. Protective gloves and following label instructions ensure safe application. Effective fertilization involves even distribution and watering after application to aid absorption.
