Comparison: Best Potting Soil Kellogg (Updated | Nov 11th)

Look for a blend that balances moisture retention with good drainage, such as mixes that combine peat, perlite, and coir. A mix certified by the Mulch & Soil Council can assure quality, and added fertilizer can reduce the need for frequent feeding. Also check if the mix is formulated to deter pests like fungus gnats.

Organic mixes, like Miracle‑Gro Organic Indoor or Outdoor, use natural fertilizers that release nutrients slowly over weeks or months, while conventional mixes often rely on synthetic nutrients for quick growth. Organic blends typically include peat, coir, and composted materials, offering better soil life and sustainability. They may be slightly more expensive but provide longer‑term feeding and a lower environmental footprint.

For larger containers, the 16‑qt bundles of Miracle‑Gro Potting Mix or Organic Outdoor Mix give the most volume per bag and feed plants for up to six months. The Moisture Control mix also includes two 8‑qt bags, but the larger 16‑qt bags usually have a lower cost‑per‑cubic‑foot ratio. Consider the specific plant needs—if you need extra water retention, Moisture Control may be worth the premium.

Yes, the Back to the Roots 100 % Organic Potting Mix is peat‑free and made from upcycled plant material, reducing carbon impact. It also includes yucca extract for moisture control and dolomitic limestone for pH balance. While it may not have the same water‑holding capacity as peat‑based mixes, it performs well for herbs, vegetables, and flowers.

Moisture‑Control mixes contain an AquaCoir formula that can absorb up to 33 % more water than standard soils, helping prevent both over‑ and under‑watering. They also include a quick‑release fertilizer that feeds plants for up to six months, promoting larger growth. This makes them ideal for busy gardeners or beginners who may miss watering cues.

The Miracle‑Gro Cactus, Palm & Citrus Potting Mix is formulated with a fast‑draining blend and added plant food, providing excellent aeration and quick water runoff. Its coarse texture mimics desert soils, reducing the risk of root rot. Use it for both indoor and outdoor containers of cacti, palms, citrus, and other succulents.

FoxFarm Ocean Forest combines aged forest products, bat guano, and fish emulsion for a nutrient‑dense, organic profile, while mainstream mixes often rely on synthetic fertilizers. Ocean Forest offers a balanced pH and superior moisture‑locking properties, making it suitable for a wide range of plants from seedlings to mature shrubs. However, it tends to be pricier than standard Miracle‑Gro options.

Choose a mix that provides steady nutrient release, good drainage, and a slightly higher organic matter content, such as Miracle‑Gro Organic Outdoor or FoxFarm Happy Frog. These blends contain natural fertilizers and microbial inoculants that support root development and fruit production. Ensure the mix is labeled safe for edible plants and consider adding a supplemental liquid fertilizer for peak harvests.
