Caring for houseplants is easy and fun with the right foundation. That's why we created Miracle-Gro® Houseplant Potting Mix. It contains the elements and nutrients indoor plants need to thrive, and it feeds for up to 6 months after potting. And because we know that bugs aren't welcome in your home, the soil is less prone to gnats, thanks to the right combination of ingredients: perlite, sphagnum peat moss, fertilizer, a wetting agent and coir. This nutrient-rich potting mix is also certified under the Mulch & Soil Council, whose mission is to define quality products that uphold industry guidelines. Plus, it’s recommended for growing Pothos, Monstera Plants, Spider Plants, and more popular indoor plant varieties. A single 4-qt. bag fills an 8-inch container. For even more spectacular results and to further support your success in growing happy houseplants, consider starting regular feedings with Miracle-Gro® Plant Food 30 days after potting your plants.
