Tomato Fertilizer 4-18-38 is a premium, 100% water-soluble fertilizer formulated for the flowering-through-harvest window of fruiting nightshade crops. The low-nitrogen, high-phosphate, very-high-potassium ratio is tuned to fruit development rather than leafy growth, with EDTA-chelated iron, manganese, zinc, and copper plus boron and molybdenum in every bag.

Potassium supports fruit sizing, sugar transport, firmness, and post-harvest quality, while available phosphate supports flowering and fruit set and the controlled 4% nitrogen keeps energy directed toward fruit. It is well suited to tomatoes, peppers, eggplants, tomatillos, and other fruiting nightshades, and dissolves cleanly for soil, container, drip fertigation, hydroponic, and 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 for a complete program. Pre-dissolve each fertilizer separately, check pH and EC, and for foliar use, spray in early morning or late afternoon below 85°F. Store sealed and dry.

CDFA registered and third-party lab tested for heavy metals, with results consistently well below required limits.

Two packs no breaks

I've ordered two packs of these now for lunch. Over the course of 2 years. Works very well. Never had a fork break. Biggest complaint with other brands is I've had forks break.
