House Plant Refresh: feed your indoor plants

Last reviewed July 1, 2026

Why houseplant soil runs out

Indoor potting mix has no way to renew itself. Outdoors, leaves fall, worms work, and rain brings fresh inputs; in your living room, none of that happens. Over months, the soil compacts, runs low on nutrients, and loses the biology that keeps roots healthy, and your plants slowly decline between repottings. House Plant Refresh re-feeds that soil so your plants stay lush, and it is made for indoor use.

How to use House Plant Refresh

House Plant Refresh is a gentle top-dress, not a potting-soil replacement - the idea is to upgrade what you already have.

  • Sprinkle a small amount around the base of the plant.
  • Work it gently into the soil surface.
  • Water.

Repeat with a light monthly top-dress during the growing season (spring through early fall), scaled to the pot size. There is no real burn risk, so it is forgiving. A 12 qt bag covers about two dozen 12-inch pots; a 6 qt bag about thirteen.

The honest indoor questions

  • Will it smell? Once it is watered in and dry, House Plant Refresh is low-odor. It is a processed, stabilized product, not raw material.
  • Will it attract fungus gnats? Gnats are drawn to constantly-wet soil, not to Refresh specifically. The fix is the same either way: let the top inch of soil dry between waterings and don't overwater.
  • Is it safe around pets and kids? It is made from natural inputs, with no harsh synthetic salts and no real burn risk. As with any garden product, store the bag away and don't let pets eat the soil.

Refresh conditions the soil you have - do not plant directly into it.
