Buying Guide
Healthy plants start with the right soil. Fertilized soils give your plants the nutrients they need to thrive. The right mix can turn your green space into a lush, vibrant oasis.
- Plant Type: Use indoor-specific soils for houseplants and outdoor mixes for gardens. Indoor blends often skip compost to cut gnat risks. Outdoor soils handle weather shifts and feed veggies, flowers, or shrubs.
- Gnat Resistance: Avoid gnat-prone soils by choosing mixes without compost or bark. Products like Miracle-Gro Houseplant Mix use perlite and coir to deter pests.
- Organic vs. Non-Organic: Pick OMRI-listed soils for organic gardening. Organic options like Miracle-Gro Organic Mix use natural fertilizers. Non-organic blends often feed plants longer.
- Moisture Control: Look for soils that balance water needs. Miracle-Gro Organic Indoor Mix guards against overwatering. Craft Organic Mix drains well to keep roots healthy.
- Pot Size: Match bag size to your pots. A 4 qt. bag fills an 8-inch pot. Larger 16 qt. bags suit 12-inch containers. Check product labels for coverage.
- Duration of Nutrients: Some soils feed plants for up to 6 months. Others, like Miracle-Gro Organic Outdoor Mix, last 2 months. Choose based on how often you want to re-fertilize.
