Description

Jack's ClassiCote® 15-8-23 with Crystal Green® is a time-release fertilizer that feeds your plants for up to 4 months. Its controlled release nutrients reach the plant in small increments, giving roots time to absorb them instead of washing away.

Crystal Green is a highly pure, crystalline source of phosphorus and magnesium captured from wastewater, a renewable nutrient that would otherwise be lost as waste. Blended with enhanced micronutrient availability, it supports strong roots and vital green growth.

ClassiCote is made for fruiting and flowering plants, indoors and out. Use it in vegetable gardens and patio gardens, on roses and shrubs, with bulbs and flowering containers, and around trees and turf.

Apply it at the rate printed on the label. Because it releases slowly, one application keeps feeding for up to 4 months. The numbers 15-8-23 are the guaranteed percentages of nitrogen, phosphate and potash.

ClassiCote comes in a 2 lb jar.
