How to choose organic fertilizers and soil amendments
Start by deciding what you are trying to fix. Fertilizers feed plants, while amendments change the soil itself. Blended fertilizers such as Down To Earth and Happy Frog formulas are balanced for a plant type, like citrus, fruit and flower, or acid-loving ornamentals, and are the simplest choice for most gardeners. Single-ingredient meals let you target one need, such as a nitrogen source or a phosphorus source, once you know what your soil is missing.
- Manures, compost and mineral amendments such as Azomite build soil structure and trace minerals over time rather than giving a quick feed.
- Liquid fish fertilizers, like Alaska Fish Fertilizer, act faster and suit mid-season top-ups.
- Granular products release slowly as soil microbes break them down, so apply ahead of peak demand and keep the soil moist.
A soil test is the best way to avoid guessing, and the label on each bag is your guide for amounts. See also Soil and Grow Media and Worm Castings & Compost.
