Know before you buy
Yes, this blend is designed for reuse. Simply remove any large root balls from your previous plants, fluff the soil to restore aeration, and it is ready for your next round of planting.
While it is formulated for containers of all sizes, its high moisture retention makes it particularly effective for outdoor pots. If using indoors, ensure your containers have adequate drainage holes to prevent the soil from staying too wet.
No, this is an OMRI Listed organic product. It relies on natural amendments like compost and earthworm castings to support plant health, though we recommend incorporating a balanced organic fertilizer for optimal growth.
The compost-based formula is specifically engineered to resist breaking down over time, which is essential for large-scale containers where frequent soil replacement is difficult. It maintains its structure and drainage properties even in deep, heavy pots.
The blend uses a combination of coconut coir and compost to hold moisture, while rice hulls and aged pine bark are included to provide the necessary structure and drainage to prevent root rot.
