Buying Guide: Key Considerations For Indoor Plant Soils
- Plant type and water needs: Desert plants require fast drainage; tropicals often need consistent moisture without waterlogging.
- Organic and peat-free options: Decide if peat, coconut coir, or organic soil components align with your sustainability goals.
- Moisture retention vs. drainage balance: Look for perlite, vermiculite, or bit of coco coir to tune water movement.
- Nutrient provisions: Some mixes include long-lasting fertilizer; others are designed for clean growth without added nutrients.
- Risk of fungus gnats: Avoid mixes containing compost or bark if gnats are a concern; consider pre-moistened or gnat-resistant blends if needed.
- Container and plant size: Larger pots or fast-growing plants may need richer mixes; smaller pots benefit from lighter, well-draining blends.
