Diatomaceous Earth Potting Soil Improver Feed Grade - Organic

The organic diatomaceous earth potting soil and compost improver is designed to improve soil quality in pots and garden beds. It absorbs and releases water gradually, preventing soil from drying out too quickly while maintaining airflow and preventing compaction. It also holds onto nutrients, releasing them slowly to help plants access essential feeding for healthy growth.

Diatomaceous Earth For Potting Soil And Compost

Adding diatomaceous earth to your potting soil improves its texture and prevents it from becoming compacted. Its porous nature increases drainage while retaining moisture, making it especially valuable for peat-free and compost-based mixes. This helps roots breathe, access nutrients and grow more efficiently.

How To Improve Soil Quality In Pots With Diatomaceous Earth

Mixing 10–20% by volume into compost provides an instant boost to soil structure, moisture control and nutrient retention. A thin top layer can also help reduce water evaporation and discourage crawling pests such as fungus gnats. This keeps plants healthier and reduces stress caused by uneven watering.
