Soil and root health are shaped by watering, drainage, light and season as much as by what you add, so this is one part of overall plant care.
Feeds foliage for deeper color and a brighter, more lively look.
Encourages fresh leaf and stem growth for a fuller, thriving plant.
Supports healthy resilient roots that absorb nutrients more effectively.
Watering can
1 tsp per quart (32 oz) of water
Spring & summer: every 1–2 weeks · Fall & winter: every 4 weeks
Bright, indirect light suits most of these plants: right by an east window, or a few feet back from a south one. Direct afternoon sun scorches calathea and peace lily.
Water when the top inch or two of mix feels dry, until it runs from the drainage hole, then empty the saucer. Snake plants and ZZ plants want longer dry spells.
A loose, well-draining potting mix with bark or perlite in it. Aroids such as monstera and philodendron sit unhappily in dense soil that stays wet for days.
Average room humidity suits pothos and snake plants, while calathea and fiddle leaf fig prefer 50 percent or higher. Group plants together or run a humidifier in winter.
Houseplant Root Supplement is a root product rather than a complete feed, so use it alongside your regular houseplant fertilizer, especially around repotting, propagation and other root stress.
Move up one pot size when roots circle the bottom, usually every one to two years in spring. Loosen the root ball and use fresh mix, not garden soil.
Houseplant Root Supplement is meant to ride along with your regular watering rather than be a separate routine. Mix 1 teaspoon per quart of water and apply every 1–2 weeks in spring and summer, then every 4 weeks in fall and winter. Because it carries no NPK, one dilution suits every plant in the house, so you can water the whole collection from the same can without mixing per plant.
All of them. Houseplant Root Supplement is built as one supplement for a mixed collection: pothos, philodendron, monstera, snake plants, ZZ plants, ferns, palms, peace lilies, calathea and the rest. There’s no NPK in the formula, so there’s no risk of giving a light feeder more fertilizer than it wants. The kelp, probiotics, surfactants and fulvic acid do the same work at root level regardless of what is growing above the soil.
It’s a supplement, not a fertilizer; there is no NPK in it. Houseplant Root Supplement carries kelp for new root growth, a probiotic blend of beneficial microbes, plant-derived surfactants so water soaks in evenly, and fulvic acid to help carry minerals into the roots. Those build root health and improve how well roots take up water and nutrients, but your plants still need actual nutrition from a fertilizer. The two work together: this makes the root system better at using what your plant food delivers.
Peat-based potting mixes turn water-repellent once they dry out fully. Water beads on the surface, slides down the gap between soil and pot, and exits the drainage holes while the root ball stays dry. The plant-derived surfactants in Houseplant Root Supplement break that surface tension so moisture and nutrients spread evenly through the soil again. For a badly dried pot, bottom-water once to rewet it thoroughly, then resume normal watering with the supplement mixed in.
It supports the rebuild, but fix the cause first. Rot means the soil has stayed wet too long, so trim mushy roots back to firm tissue, repot in fresh, well-draining mix if the damage is extensive, and let the soil dry more between waterings; roots need air as well as water. From there, the probiotics in Houseplant Root Supplement help beneficial microbes establish in the fresh mix, and the kelp supports the new root growth your plant needs to recover.
Roots recover before the leaves show it. Within 2–4 weeks of regular use, expect pots that rewet easily when watered instead of shedding water, and plants that hold steady rather than declining. Visible growth follows in the growing season, typically 4–8 weeks, as rebuilt root capacity turns into new leaves. Slow growers like ZZ and snake plants take longer to show a change than pothos or philodendron, so judge them on a longer timeline.
