Coast of Maine Castine Blend Organic & Natural Raised Bed Mix | 1cu ft - OMRI Listed

Enriched Raised Bed Mix with Ten Natural Inputs

Raised beds don't have the surrounding soil ecology a garden bed benefits from, so what goes into the bed at the start carries more of the season's nutrition than it would in the ground. Coast of Maine's Castine Blend is built around that gap, combining fully cured compost, peat, biochar, worm castings, dehydrated poultry manure, kelp meal, lobster meal, greensand, lime, and mycorrhizae into one enriched mix.

This 1cu ft bag is OMRI Listed and formulated specifically for growing vegetables, herbs, and flowers in raised beds rather than as a general potting soil.
