Organic Gardening Products: Natural Fertilizers & Amendments

Building fertile soil organically means feeding the microbial life that feeds your plants. These natural amendments provide slow-release nutrition while improving soil structure.

Key Organic Fertilizers & Their Roles

Blood Meal (12-0-0): Fast-acting nitrogen for leafy growth. Also deters rabbits/deer when sprinkled on soil surface. Use sparingly—can burn.

Bone Meal (3-15-0): Slow-release phosphorus for root development and flowering. Ideal for bulbs, tomatoes, peppers at planting.

Kelp Meal (1-0-2) & Liquid Kelp: Rich in micronutrients, growth hormones (cytokinins), and stress tolerance compounds. Foliar spray every 2–3 weeks boosts vigor.

Fish Emulsion/Hydrolysate (5-1-1): Balanced, quick-acting. Smelly but plants love it. Great for seedlings and container feeding.

Greensand (0-0-3): Slow potassium source plus trace minerals. Improves clay soil texture. Long-term soil conditioner.

Rock Phosphate (0-3-0): Very slow phosphorus. Best for acidic soils; takes years to fully release. Good for perennial beds.

Alfalfa Meal (2.5-0.5-2.5): Contains triacontanol, a natural growth stimulant. Excellent for roses and compost activator.

Smart Application

Soil test first (university extension labs are affordable). Amend based on deficits, not habit. Over-fertilizing organics still causes nutrient runoff. Blend dry meals into soil at planting or top-dress and water in. Liquids apply as root drench or foliar spray early morning.

Right Plant, Right Place

Even the best amendments can't fix a sun-lover in shade or a water-hater in clay. Match plants to your site's light, moisture, and soil type. Healthy plants in suitable locations need fewer inputs.
