Comparison: Best Miracle Gro Organic Choice (Updated | Nov 11th)

A potting mix, like the Miracle‑Gro Organic Outdoor Potting Mix, provides the growing medium and includes a slow‑release fertilizer that feeds for up to two months. Liquid plant food, such as Miracle‑Gro Organic Plant Food, is a concentrate you dilute with water to give an immediate nutrient boost. Choose a mix when you need soil replacement, and a liquid feed when you want quick, targeted nutrition.

For a vegetable garden planted in‑ground, the Miracle‑Gro Organic All Purpose Plant Food granules work well because they feed for up to three months and can be mixed into the top few inches of soil. For container herbs, the Performance Organics All Purpose Container Mix gives a ready‑to‑use, organic medium that supplies nutrients for the entire season. Both are OMRI‑listed, but the mix eliminates the need for separate fertilizer.

Buying bundled packs, such as the 2‑pack of 32 oz. Organic Plant Food or the two‑bag bundle of the Outdoor Potting Mix, reduces per‑unit price compared to single items. Pairing a 16 qt. container mix with a 2‑pack of liquid food gives you a complete planting solution at a lower overall cost than purchasing each separately.

Performance Organics granules are formulated for specific purposes—Edibles for vegetables and fruits, Blooms for flowering plants—while the Organic All Purpose granules are a universal blend for any outdoor plant. The Edibles and Blooms versions are OMRI‑listed and emphasize higher yields or more blooms, whereas the All Purpose product focuses on overall vigor and resilience.

Yes, the Outdoor Potting Mix can be used for indoor containers, but it is optimized for outdoor conditions and includes a quick‑release fertilizer that may be stronger than needed for low‑light indoor plants. For indoor use, the Performance Organics All Purpose Container Mix is a better match because it’s designed for both indoor and outdoor containers and provides a balanced nutrient release over three months.

Liquid feeds like Miracle‑Gro Organic Plant Food are typically applied every 7–14 days, depending on plant type and growth stage. Granular feeds, whether Performance Organics or Organic All Purpose, are usually reapplied every 4–6 weeks, allowing the nutrients to release slowly over time. Following the label directions ensures you avoid over‑feeding while maintaining healthy growth.

Check for the OMRI (Organic Materials Review Institute) listing, which indicates the product meets USDA organic standards. Look for statements about plant‑based ingredients, such as “94 % plant‑based fertilizer,” and certifications that the peat or compost is responsibly sourced. These cues guarantee the product aligns with organic gardening practices.
