- OMRI Certified Potting Mix
- 1.5 Cu Ft Bag
- Mycorrhizae-Enhanced Rooting
- Large Container Ready
Stonington Blend™ Organic & Natural Grower's Mix fills big containers with a quality mix that holds moisture but still drains cleanly. This 1.5 cu ft premium blend combines sphagnum peat moss, composted manure, coconut coir, and perlite, then charges it with organic nutrition from inputs like lobster and crab shell meal, kelp meal, fish bone meal, and earthworm castings. It’s designed to keep plants growing steadily in larger pots. Use it for 10–15 gallon planters when you want fewer watering headaches and a mix that stays airy as roots fill in.
The texture is tuned for strong container growth, so it’s a good fit for heavy feeders like vegetables, flowering annual combos, and other crops that spend a full season in a pot. Mycorrhizae microorganisms (Glomus intraradices) support water and nutrient uptake, which is especially helpful once summer heat pushes containers hard. Use it straight in clean pots with drainage holes, and plan on occasional feeding as plants size up.

Product Tips
- Pre-moisten the mix before filling large containers so the peat and coir hydrate evenly.
- Don’t pack it down hard; a light settle keeps the drainage and air space working.
- Water when the mix feels slightly dry to the touch, not just when the surface changes color.
- Feed during the season as plants demand it, especially in fruiting vegetables and heavy-blooming containers.
- Store unused mix in a cool, dry, shaded spot to help protect the mycorrhizae.

Does it contain mycorrhizae?
Yes. It includes endomycorrhizae (Glomus intraradices) at 0.07 spores per gram.
