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 and 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 in. 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.
