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

First, decide whether the plants are indoor or outdoor, because moisture‑retention and drainage needs differ. Look for mixes that list specific ingredients like perlite, coir, or peat to match the plant’s water preferences. Check if the product includes a built‑in fertilizer and how long that feed lasts. Finally, compare bag size and coverage to ensure you get the best price per square foot.

Both are formulated for indoor use, but the Houseplant mix emphasizes a blend of perlite, sphagnum and peat that reduces gnats and adds extra aeration. The Indoor mix uses coconut coir and a quick‑start natural fertilizer, focusing on moisture‑holding capacity. The Houseplant version is sold in a 4‑qt bag, while the Indoor mix comes in larger 16‑qt bags for bigger projects.

Yes, it offers a peat‑free, fully organic formula made from upcycled plant material, which appeals to eco‑conscious gardeners. It includes yucca extract for moisture control and dolomitic limestone for pH balance, providing similar growth support without synthetic fertilizers. The mix is sold in a 12‑quart value bag, making it competitively priced for the amount of soil you receive.

The Miracle‑Gro Cactus, Palm & Citrus Potting Mix is designed specifically for fast‑draining conditions that succulents love. It contains a blend of sand, perlite and a light fertilizer to prevent water‑logging while still feeding the plants. The product is packaged as two 8‑qt bags, each enough for two 8‑inch containers, which is ideal for small cactus collections.

Moisture Control uses an AquaCoir formula that absorbs up to 33 % more water than typical peat‑based soils, helping prevent both over‑ and under‑watering. It also feeds plants for up to six months, promoting larger growth without additional fertilization. The mix comes in a two‑bag bundle (8 qt each), offering good coverage for multiple containers.

The Organic Outdoor mix contains a quick‑release natural fertilizer that feeds plants for up to two months, which is shorter than the six‑month feed found in many standard Miracle‑Gro blends. It’s ideal for gardeners who prefer a more natural, less synthetic nutrient source. One 16‑qt bag fills a 12‑inch container, making it a practical size for larger outdoor beds.

Both the Miracle‑Gro Houseplant Potting Mix and the Indoor Potting Mix are formulated without compost or bark, which are common gnat habitats, making them less prone to infestations. The Back to the Roots Indoor mix also avoids these ingredients and adds organic yucca extract for added pest resistance. Choosing any of these gnat‑friendly mixes can lessen the need for chemical controls.

Check the stated coverage: a 4‑qt bag typically fills an 8‑inch pot, while a 16‑qt bag is meant for a 12‑inch container. Larger bags often lower the cost per cubic foot, but ensure you have enough storage space. Bundles (two 8‑qt bags or two 16‑qt bags) can provide a discount and are handy for multiple projects or larger garden beds.
