Derived from leguminous perennial alfalfa plant used for pasture and cover crop. Primary benefit of this pleasant smelling meal is increasing organic matter, although it is also a valuable plant-derived fertilizer. Also contains trace minerals and triaconatol. Excellent addition to the compost pile for nitrogen content and absorbency. Roses respond especially well to alfalfa meal. For new plantings of roses, mix 0.5 cup per plant into the soil. For existing plants, mix 0.5-1 cup of alfalfa meal to a depth of 4"-6" around each rose bush. For vegetables and flower beds, work in at 2-5 lbs/100 sq ft.
