Strawberry Fertilizer 8-12-32 is a premium, 100% water-soluble specialty formula built specifically for strawberries — June-bearing, everbearing, and day-neutral. The moderate 8% nitrogen, enhanced 12% available phosphate, and very high 32% soluble potash are tuned to the strawberry's fruiting window, with EDTA-chelated iron, manganese, zinc, and copper plus boron and molybdenum.
Potassium supports sugar movement to developing fruit, cell water balance, firmness, and shelf life, while the moderate nitrogen avoids the soft berries and excess runners that come from overfeeding. Strawberries are also EC-sensitive, and the potassium-forward but moderate-nitrogen profile helps meet potassium demand without driving solution salinity too high. It dissolves cleanly for per-plant soil feeding, container growing, drip fertigation, hydroponic towers and NFT, and targeted foliar use.
This formula does not contain calcium by design — calcium and phosphate should not be combined in concentrated stock solution, so a separate calcium source should be applied independently. It is an oxidizing solid, so keep it away from heat, flame, and combustible materials. Pre-dissolve each fertilizer separately, follow label crop restrictions, and store sealed and dry.
CDFA registered and third-party lab tested for heavy metals, with results consistently well below required limits.
