Houseplant Chunky Mix is our all-purpose, aroid, or tropical potting mix. It contains the most organic matter of all our products to ensure that your houseplants get all the moisture and drainage they need to thrive. If the plant is leafy, it's probably looking for this mix.WHEN SHOULD I WATER? Despite these specialized mixes containing more chunky/gritty components compared to other soil mixes, they hang onto moisture for the root ball effectively. No need to water more frequently! Generally for indoor settings with established plants, one deep watering every 10-14 days is usually plenty. Watering weekly will likely still lead to root rot or gnats if the root system doesn't get a chance to fully breathe between watering sessions.
