Know before you buy
The high phosphorus content (52%) is specifically formulated to stimulate root development and encourage prolific blooming. It is best used when you want to transition a plant from vegetative growth into its flowering or fruiting stage.
Yes, this formula is versatile enough for vegetables, flowers, trees, shrubs, and houseplants. However, because it is a bloom-booster, it is most effective for plants that are actively preparing to flower or fruit rather than those grown primarily for their foliage.
As a water-soluble, quick-release fertilizer, the nutrients are available to the plant almost immediately upon application. This makes it an excellent choice for correcting deficiencies or providing a rapid boost during critical growth phases.
Yes, the high solubility and purity of this powder make it well-suited for use in irrigation systems or standard watering cans. It dissolves completely in water, which prevents clogging and ensures even nutrient distribution.
To prevent clumping and maintain the integrity of the minerals, store the container in a cool, dry place with the lid tightly sealed. Keep it away from direct moisture, as the powder is highly hygroscopic and will absorb humidity from the air.
No, this is a specialized supplement rather than a balanced all-purpose fertilizer. It is intended to be used during specific periods, such as when you are encouraging bud set or establishing new root systems, rather than as a continuous feed for general maintenance.
