Healthy plants are better at resisting disease, fungus, and pest outbreaks, and this soil helps get your plants to that point. The slow-release nature of these high-quality compounds allows the plant to feed when it needs to and lessens the need for you to add any fertilizers. Ocean Forest is a blend of nutrient-rich natural ingredients, including worm castings, seaweed, bat guano, and coconut coir. Size: 3 pounds︱ Type: All indoor plants, including aroids︱ Ingredients: Earthworm castings, mycorrhizae, composted materials︱ Organic: Yes The manufacturer recommends only a third of a cup for a 4-inch pot. You also can use it to start an indoor plant from seed. To use Wonder Soil, which has a slow-release form of nitrogen, you just transplant the plant and add the product. Wonder Soil also is pre-mixed with garden soil mix, so it’s a plant starter as well.

The product also contains mycorrhizae-fungal roots which can help plants better ingest nutrients and may add protection against diseases that reside in soil. The manufacturer claims that when mixed with water, the product expands from 3 pounds in the resealable bag to 12 quarts of indoor soil. We like the coco coir in this product because it expands, keeping plants moist for longer, meaning you need to water less frequently.

In addition to earthworm castings, kelp, and perlite, all of which provide indoor plants with the nutrients they need to grow their best, Wonder Soil also contains coco coir, commonly used as a bonus-type growth medium. All that earns this product our Best Overall selection. Wonder Soil Premium Organic Potting Mix does this, adds more ingredients and more to help indoor plants thrive, and can be used with just about any plant. Most potting soil for indoor plants contains the essential nutrients to give new greenery a good jump start or transplants the food they need.
