For Improving Native Soil and Protecting Plant Roots

Gardner & Bloome Organics Soil Building Conditioner serves two purposes in your garden. As a soil amendment, it loosens clay soils, improves aeration, and helps your native soil hold water more efficiently when mixed in. As a top mulch, it protects roots, conserves moisture, and helps maintain steady soil temperature.

The blend contains beneficial mycorrhizae that work with plant roots to support strong, healthy growth. Use it on flowers, shrubs, and trees in any garden setting.

How to Use Soil Building Conditioner

  1. As a Soil Amendment: Mix Soil Building Conditioner into your native soil at about 1 part conditioner to 2 parts soil. Especially useful for compacted or clay soils.
  2. As a Top Mulch: Spread a 2 to 3 inch layer around the base of trees, shrubs, and flowers. Keep mulch a few inches away from trunks and stems.
  3. For New Plantings: Mix into the planting hole to give roots an excellent starting environment.
  4. Feed Through the Season: Pair with Gardner & Bloome Organics All Purpose Organic Fertilizer for steady plant nutrition.
