LGM
LGM Cactus & Succulent Soil Mix, 0.5 Cu Ft

- Naturally Nourished Soil: Chicken manure, kelp meal, and iron sulfate feed plants with natural nutrients over time. This organic, OMRI Listed blend contains no synthetic fertilizers, so nutrition comes from the ingredients themselves, not a separate feeding routine.
- More Than A Cactus Mix: The same fast-draining formula that suits cacti, aloe, and other succulents also supports citrus trees, palms, and plumeria, plants that typically need more drainage than a standard all-purpose potting soil provides.
- Family Owned Since 1946: Formulated in California by LGM Soil Amendments using composted forest products and other quality natural ingredients, built on decades of experience blending soil for real growing conditions.
- Ready To Use, Indoor Or Outdoor: This 0.5 cu ft bag goes straight from the bag into pots, planters, and containers with no mixing required, sized for home succulent and cactus collections rather than large-scale planting.
