Know before you buy
This fertilizer follows the specific nutrient research conducted at Michigan State University, which identified the precise mineral requirements for orchids. Unlike many generic fertilizers, it is urea-free, ensuring your orchids can properly absorb nitrogen without the need for soil microbes to break it down.
This formula is specifically optimized for reverse osmosis, rain, or low-alkalinity water. If your tap water is high in alkalinity or minerals, this fertilizer may not perform as intended, as the formulation relies on the water source to maintain the correct pH balance.
Orchids are epiphytes that typically grow on trees rather than in soil, meaning they lack the specific bacteria required to convert urea into a usable form of nitrogen. A urea-free formula provides nitrogen in a form the plant can immediately absorb, preventing potential root burn and nutrient deficiencies.
This ratio provides a high concentration of nitrogen for healthy foliage growth and potash for strong root systems and vibrant blooms. The inclusion of 8% calcium and 2.6% magnesium further supports structural integrity and essential metabolic functions in your plants.
Yes, while it is specifically formulated for the needs of orchids, its balanced macronutrient and micronutrient profile makes it an excellent choice for other prized, sensitive plants that thrive in similar growing conditions.
