Our hand-blended soil mixes were created by a plant lover and a scientist to bring your plants the absolute best substrate for them to thrive! All blends contain Slowdirt, which is an organic pest defense. This means not only will you have the best soil, but it's treated with a preventative against soil pests, saving you time and money. While there is really no such thing as an "all purpose" soil, this would be the closest in our eyes. The Aroid mix is formulated for plants of the Araceae plant family such as pothos, philodendrons, peperomia, and most other tropical plants. 1 Quart size bag.
