Potting Soil & Soil Amendments for the northwest gardener

Swansons is pleased to offer a variety of high quality potting soils and soil amendments suited to your preference and garden situation.

POTTING SOILS are specially formulated for containers, to enhance root development and provide excellent drainage. They generally should not be used to amend garden soil.

SOIL AMENDMENTS (such as Compost) add organic matter to your soil. The integrity of your soil depends a lot on organic matter. As it breaks down into humus it improves the ability of soil to retain water and nutrients, and helps soil particles bind together to form structure in which water, air and roots can move freely. It also feeds beneficial soil microbes and fungi which in turn break down and transport nutrients to the roots.

Sandy soils (gritty and loose with large particles) need extra organic matter to improve the ability to hold water and nutrients in the root zone. In heavy clay soils (sticky when wet, powdery or chunky when dry), organic matter provides new air spaces for water to drain and roots to grow.

When adding amendments, work into existing soil as deeply as possible without disturbing existing roots. Never dig in soil that is saturated, as it will compact.

Swansons features high quality Gardner & Bloome® and E.B. Stone® soil products along with several specialty products. Please ask us if you have further questions!
