Living Potting Mix
Give your plants the best head start.
A farm-tested, all-natural potting mix packed with worm castings, mycorrhizae, and slow-release organics — feeds your plants for 6+ months right out of the bag.
Key benefits
🪱 Worm castings
Beneficial soil microorganisms that stimulate plant growth and build natural disease resistance from day one
🍄 Mycorrhizae
Forms a symbiosis with plant roots to help uptake more moisture and nutrients throughout the season
🌿 Slow-release organics
Organic and regionally sourced nutrients supply plants with what they need for months — no synthetic spikes
💧 Moisture & nutrient holding
Peat moss and composted wood fines provide exceptional moisture and nutrient retention for healthy roots
💨 Excellent airflow
Perlite and rice hulls provide excellent airflow to developing roots — preventing compaction and rot
🌍 AZOMITE® minerals
Trace minerals replenish what modern soils are missing for stronger, more resilient plants
How it works
Most potting mixes are inert — they hold plants up but don’t actively feed them. Living Potting Mix is different. Every bag contains a living community of beneficial microorganisms from worm castings, plus mycorrhizal fungi that form a direct partnership with your plant’s roots.
That biology unlocks nutrients already present in the mix, improves water retention, and builds the kind of root-soil relationship that takes years to develop in garden beds — right from the moment you plant.
