All-Purpose Houseplant Food (Dry) 21-7-14

A chloride-free, fully water-soluble houseplant food built on the UF/IFAS 3:1:2 (N:P2O5:K2O) optimum for container plants, then back-engineered so a level teaspoon lands on research-based nitrogen targets. The 21-7-14 grade holds an exact 3:1:2 ratio with no filler, and includes 2% magnesium, labeled sulfur, and a full chelated micronutrient package. A level 1/2 teaspoon per gallon delivers about 140 ppm nitrogen — the all-purpose feeding rate for most foliage houseplants. Calcium is intentionally omitted (it cannot share a bag with phosphate and sulfate); RO-water growers should add calcium separately. Blended in our CDFA-registered, third-party lab-tested Madera, California facility. Available in 1, 2, 5, 10, and 25 lb sizes.
