Now that the sun is starting to shine again and the nights are warming up, the gardening "rubber" is about to meet the road! We here at Sea Spray are big believers in organic best practices. But if you are new to organic growing and used to old fashioned 10-10-10 granular fertilizers? Well, new soil inputs can be a bit overwhelming. So today we want to spotlight a lesser known but super valuable soil amendment and that is alfalfa meal!! Alfalfa meal is an under the radar rockstar for the home gardener.
A nitrogen source — releases ~2-3% N slowly as it breaks down, feeding plants without burning roots. 🌱
Triacontanol — a natural plant growth stimulant found in alfalfa that boosts photosynthesis, root growth, and overall vigor.
Balanced NPK — roughly 2-1-2, so it delivers phosphorus and potassium alongside nitrogen.
Trace minerals — calcium, magnesium, iron, and other micronutrients.
Improves soil structure — organic matter loosens clay and helps sandy soils retain moisture.
Feeds soil microbiology — sugars and proteins fuel bacteria, fungi, and earthworms.
Stimulates compost piles — high protein content acts as a "green" activator, heating piles up fast!
Slow-release — breaks down over weeks, so less leaching than synthetic fertilizers.
It is pH neutral — won't shift soil acidity significantly.
Safe for most plants — particularly loved by roses, tomatoes, peppers, and fruit trees.
Affordable — cheaper per pound than many specialty organic fertilizers, especially if bought as livestock feed pellets.
Tip: use sparingly (around 1-2 cups per established shrub, or ½ cup per square foot in beds) — too much can heat up as it decomposes and temporarily tie up nitrogen.
