🌿 Why Growers Choose Bloom 3-12-6

SUPERthrive Bloom 3-12-6 is a powerful, low-nitrogen, high-phosphorus liquid fertilizer designed to promote vibrant blooms, bigger flowers, and denser buds. Previously labeled as Dyna-Gro Bloom, the formula remains unchanged—only the label has evolved.

This complete plant food provides all 6 essential macronutrients and all 10 micronutrients your flowering plants need to thrive. The balanced 3-12-6 ratio is ideal for stimulating flower spikes, intensifying color, and increasing flower size in orchids, African violets, roses, vegetables, and herbs. A high nitrate-to-ammoniacal nitrogen ratio helps prevent leggy growth and stretching, ensuring compact, sturdy stems and vibrant floral displays.

Whether you grow in soil, containers, hydroponics, or LECA, SUPERthrive Bloom supports maximum flower production and is safe for use with most flowering crops. It also contains enough calcium and magnesium that you won’t need additional Cal-Mag supplementation.
