Description
Diatomaceous earth is a peat free soil improver designed to support moisture balance, airflow and nutrient retention in pots and garden beds. Its porous structure helps maintain an even growing environment, making it suitable for compost mixes that dry out or compact easily.
Diatomaceous earth improver for healthier soil
When blended into compost, this mineral based additive improves texture and keeps growing media open. It holds water and releases it gradually, helping roots access moisture between watering while maintaining good drainage.
