FoxFarm Marine Cuisine for Your Garden is a powerful blend of balanced plant foods combined with Pacific Northwest sea-going fish, crab meal, shrimp meal, bat guano, and earthworm castings, natures finest soil amendment. Crab and oyster shells feed the beneficial microbes in the soil, creating a healthy soil ecosystem. While decomposing, these oyster and crab shells create ammonical nitrogen which repels harmful adult nematodes out of the growing area. Ammonical nitrogen also benefits vegetables and heavy nitrogen feeders. It offers long term feeding, though a slightly later release than American Pride due to the slower decomposition of the ocean by-products. Perfect for evergreens, azaleas, camellias, rhododendrons, dogwoods, and mix in with vegetables at time of planting for a better crop. Use only twice a year, in early spring and again in late summer. Features a resealable bag.
