Back to the Roots Organic Indoor Potting Mix is a peat-free, organic growing medium for houseplants and herbs grown in containers. Yucca extract helps the mix hold moisture, mycorrhizae support root development and nutrient uptake, and dolomitic limestone keeps pH in balance.
It contains no bark or compost, which reduces the risk of indoor gnats. Among container soil blends, this one is formulated specifically for indoor pots, so plan on a different product for outdoor beds.

A Peat-Free Mix for Houseplants and Herbs Where Fungus Gnats Are a Concern
If you keep plants in a living room, kitchen, or office, the soil you bring inside matters as much as the plant. This mix leaves out bark and compost, two ingredients that can give gnats a place to breed, so it fits your situation if you have fought soil pests indoors before.
It also suits you if you want an organic, peat-free medium for repotting houseplants or growing herbs on a windowsill. You can use it in clay pots, plastic containers, or hanging baskets, and the yucca extract helps the root zone stay evenly moist between waterings. If you are filling raised beds or large outdoor planters, a mix made for that purpose is the better match.
What to Expect from the Back to the Roots Organic Indoor Potting Mix in Real Use
Verified Amazon purchasers describe the mix as light, easy to handle, and not overly heavy when repotting. The most consistent theme is pests. Several report bags arriving free of bugs, and one who switched six months ago for pothos and spider plants says the fungus gnats are gone.
Moisture feedback lines up with the yucca extract, with reports that the mix wets easily, stays moist without turning swampy, and stretches the time between waterings. Plants named in the feedback include monstera, pothos, spider plants, tropicals, and cilantro started from seed. Some growers blend in garden compost, topsoil, or other organic soil additives rather than using it straight, and report healthy growth that way.
Two things to know going in. A repeat purchaser found a noticeable amount of decayed sticks in a third bag after two clean ones, so consistency can vary from bag to bag. Another saw a mushroom come up in a pot, which they attributed to the beneficial fungi in the mix.

Frequently Asked Questions
Does Back to the Roots indoor potting mix cause fungus gnats?
The mix is made without bark or compost, which are the ingredients that most often give fungus gnats a place to breed in bagged soil. That lowers the risk of bringing gnats into your home, but it does not make a pot immune. Gnats are drawn to soil that stays wet at the surface, so let the top layer dry between waterings and empty any standing water from saucers.
Can you start herbs and vegetables from seed in this potting mix?
Yes, you can sow seed directly into it. Cilantro has been germinated and grown on in this mix, and it is intended for indoor herbs as well as houseplants. The mix holds moisture well, which helps keep seed evenly damp during germination. If you want a richer medium for heavier feeders, you can blend in compost or topsoil, keeping in mind that added compost may reduce the gnat resistance of the original blend.
Is it normal to find sticks or mushrooms in this potting mix?
You may find some small pieces of decayed woody material in the bag, and the amount can vary from one bag to the next. You can pick out larger pieces by hand before potting. A mushroom may also appear in the pot from time to time. The mix contains beneficial fungi, and a moist, organic medium is a natural place for fungal growth. You can pull the mushroom and let the surface dry slightly if you prefer not to see it.
