How Soil Amendments Help

Healthy soil is soil that is going to promote plant growth. Soil amendments work to reduce compaction, and provide aeration to allow for proper drainage. Aerated soil will see plant nutrients better reaching roots, and will help with moisture retention. Organic matter used for the soil amendments will also decompose to provide nutrients for the plants. Soil amendments can restore fertility to soil, and with the right drainage offer the best growing environment for your crops.

Why We Choose Organic

Organic living starts with the soil we grow our food in, and it is the start of nurturing a healthy ecosystem. Healthy soil supports beneficial microorganisms that contribute to strong plant growth, which in turn leads to sustainable gardens that are naturally pest-resistant. Chemicals will not only ultimately make their way onto our dinner plates, but they will destroy and do more harm to the soil we grow our food in. Organic living and growing protects our ecosystem, and protects us.
