Frequently Asked Questions (FAQs)
1. Is phosphate good for your lawn?
Phosphorus stimulates root growth and enhances plant vigor early in the plant's life. Phosphorus is most important when the grass is first establishing roots and remains important as new blades of grass continue to grow. The presence of phosphorus helps keep the lawn lush and thick.
2. What lawn fertilizer is high in phosphorus?
Pennington UltraGreen Starter Fertilizer 22-23-4, designed specifically to help new lawn grass establish, contains plentiful phosphorus and a higher percentage of potassium. These two nutrients support the development of strong, vigorous new roots and vigorous overall growth.
3. When should I apply phosphorus to my lawn?
The best time to apply phosphorus fertilizer is following aeration of turf in spring or early fall. Aeration is often necessary in compacted or poorly drained soils.
4. Why is phosphorus fertilizer banned?
Where excess phosphorus drifts into rivers, lakes, and streams, high levels of the nutrient can lead to algae build-up, harming, even killing fish, and even limiting recreational use. Phosphorus from farm fields and home lawns has been held responsible for this excess runoff and what amounts to nutrient contamination.
