Rock Phosphate 0-3-0


Down To Earth™ Rock Phosphate, a natural source of Phosphorus and Calcium, is essential for building soil phosphate levels for long-term plant productivity and for preventing calcium deficient soils. It should be applied to soils prior to planting and can be mixed with compost or manures for additional soil building benefits. This premium powder grade powers rooting, fruiting and flowering in plants, and is an excellent nutrient resource for all types of flowering plants including bulbs, fruits, shrubs, trees and vegetables. Soft rock phosphorus is an untreated, mined material and is available more quickly and over a wider range of soils than hard rock phosphate. Mix into soil several months before planting or add to an active compost pile weeks before use.

Directions: Use 2.5-5lbs for 100 sq. feet of garden soil
