Your plants and landscape will get the nutrients they need all season long from Jack's ClassiCote with Crystal Green. This time-release fertilizer is now formulated using Crystal Green, a highly pure, crystalline compound with innovative green technology that captures nutrients from wastewater. ClassiCote 15-8-23 feeds your plants in a sustainable earth-friendly way utilizing a renewable, slowly available source of phosphorus and magnesium that would otherwise be lost as waste. The controlled-release nutrients are available to the plant in small increments, giving time for absorption instead of washing away.

This plant fertilizer blend with enhanced micronutrients availability provides four months optimal nutrition for strong roots and vital green growth. The balance of 15% nitrogen, 8% phosphate and 23% potash means an NPK ratio of roughly 3-1-2, which is ideal for lawns as well as many plants, shrubs and non-flowering trees. We offer four-gallon shaker jugs of Jack’s ClassiCote Plant Fertilizer for hobby gardeners and large 25-pound bags for landscaping or commercial growing.
