Know before you buy
The high middle number, 58, indicates a very high phosphorus content, which is specifically formulated to trigger heavy blooming and support root development. The 9% nitrogen supports steady growth, while the 8% potassium helps with overall plant health and stress tolerance.
While it is primarily marketed as a blossom booster, the formula is safe for lawns and can be used to help establish new grass or encourage root development in existing turf. However, because it is phosphorus-heavy, it is best used as a targeted treatment rather than a general-purpose lawn fertilizer.
This product is water-soluble and designed for easy application. You can mix it into a standard sprinkling can for individual plants or use a hose-end sprayer for larger areas like garden beds or lawns.
Yes, it is excellent for container plants. Because container-grown plants often lose nutrients through frequent watering, the trace elements in this formula help replenish the soil and sustain consistent flowering throughout the season.
Yes, it includes essential trace elements, specifically 0.12% iron, 0.05% manganese, and 0.05% zinc. These micronutrients are vital for preventing deficiencies and ensuring your plants have the necessary components for vibrant, healthy growth.
