Marine Cuisine is a powerful blend of balanced plant foods combined with Pacific Northwest sea-going fish, crab meal, shrimp meal, bat guano, and earthworm castings. Crab and oyster shells feed beneficial microbes in the soil, creating a healthy soil ecosystem. While decomposing, these oyster and crab shells create a ammonic nitrogen which repels harmful adult nematodes out of the growing area. Ammonical nitrogen also benefits vegetables and heavy nitrogen feeders. Marine Cuisine offers long term feeding, through 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 the time of planting for a better crop. Use only twice a year, in early spring and again in late summer.
