Houseplant Root Supplement

Add 1 tsp per quart (32 oz) of water and apply every 1-2 weeks in spring and summer, then every 4 weeks in fall and winter. Mix it into your normal watering — no separate routine needed. One dilution covers your whole collection, so you can water everything from the same can rather than mixing per plant.

At 1 tsp per quart, the 8 oz bottle makes about 48 watering cans of feed. For a typical shelf of 10–15 plants fed every 1–2 weeks in season, that's several months of feeding — and the 32 oz bottle four times that.

All of them — it's built as one supplement for a mixed collection: pothos, philodendron, monstera, snake plants, ferns, palms, peace lilies, and the rest. Because there's no NPK, there's no risk of giving a light feeder too much fertilizer. The kelp, probiotics, and surfactants do the same root-level work regardless of what's growing above the soil.

It's a supplement, not a fertilizer — there's no NPK in it. Kelp, probiotics, surfactants, and fulvic acid 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 with the root ball still dry. The surfactants in this formula break that surface tension so water soaks in evenly again. For a badly dried pot, bottom-water once to rewet it, then resume normal watering.

It supports the rebuild, but fix the cause first: rot means the soil stays wet too long, so trim mushy roots back to firm tissue, repot in fresh well-draining mix if it's bad, and let the soil dry more between waterings — as the label says, roots need air. From there, the probiotics help healthy microbes establish and the kelp supports new root growth.

Roots recover before leaves show it. Within 2-4 weeks of regular use, expect plants that hold steady and rewet easily when watered rather than shedding water. 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 change than pothos or philodendron.
