Know before you buy
Yes, this formula is versatile and safe for trees, shrubs, roses, annuals, and perennials. It is specifically designed to help any new plant establish its root system quickly after being moved or planted.
The high middle number (10) indicates a higher phosphorus content, which is essential for root development. This ratio provides the specific nutrients needed to support underground growth rather than just foliage production.
No, this is a starter solution intended to be used during the initial planting phase to reduce shock and encourage root growth. Once your plants are established, you should switch to a fertilizer appropriate for their specific growth stage.
These ingredients act as growth stimulants. Vitamin B-1 helps reduce transplant shock, while indole butyric acid is a plant hormone that directly triggers and accelerates the development of new roots.
Always refer to the label on the bottle for the exact dilution ratio, as application rates can vary based on the type of plant. Generally, you will mix the concentrate with water and apply it directly to the soil around the root zone.
