Organic Alfalfa Meal 2.5-0-2.5 is a finely ground, non-GMO organic soil amendment made from the whole dried alfalfa plant. It supplies modest, slow-release nitrogen and an equal amount of soluble potash (K₂O), adds organic matter, and feeds the beneficial soil microbes that cycle nutrients to plants — which makes it a long-favored choice for roses, vegetable and flower beds, trees and shrubs, and compost activation.
Nutrients become available gradually over roughly 4 to 8 weeks as soil microbes mineralize the meal, so alfalfa meal feeds steadily without the flush-and-crash cycle of soluble fertilizers, and carries low burn risk at recommended rates. Alfalfa meal also naturally contains triacontanol, a long-chain fatty alcohol studied for effects on plant growth — though at practical garden rates its primary value is as a slow-release nutrient source and soil conditioner.
It is best used as a pre-plant, incorporated amendment rather than a quick side-dress feed — work it into the soil and water in, ideally one to two weeks before planting, since decomposition generates heat. It contains no available phosphate, so pair it with a phosphorus source for a complete program. It has a near-neutral to slightly alkaline reaction and is not recommended for acid-loving plants such as blueberries, azaleas, and rhododendrons. Microbial breakdown slows in cold or sterile media. Store sealed and dry. CDFA registered and independently lab tested for heavy metals, with results consistently well below required limits.
