How does Osmocote react with other fertilizers or plant food products?
Professional growers frequently use a water-soluble fertilizer in addition to Osmocote. Water-soluble fertilizer is absorbed partially through the leaves (foliar feeding). This compliments the root-feeding properties of Osmocote. When using a water-soluble product with Osmocote, be sure to follow the recommended rate on its package but then cut that amount by half. Typically, a water-soluble fertilizer has a roughly two-week impact on the plant, but meanwhile, Osmocote goes right on feeding for up to four months!
