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. Follow the simple instructions or call our sales associates to get answers to any questions about this high-quality plant food.

DONT WASTE YOUR MONEY!
Style: Original, Size: Standard/Queen
I ordered 4 pillows and paid almost $100 for them. They're absolutely pitiful! I could have bought better pillows at Walmart. They're soft and thin. Not at all what I was expecting.

Puffed out to be fluffiest pillows yet.
Style: Original, Size: Standard/Queen
When I received my two pillows I was concerned they wouldn't be as fluffy as advertised; they came rolled up and shoved in a small box. However, after some time sitting out they are even fluffier than imagined. Firmness is exactly what I wanted and even after my husband folds them, they bounce back to their previous shape.
