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 light with several hours of direct sun. Stretching stems and pale new growth mean more light is needed, and plants moved outdoors should be shaded at first.
Soak thoroughly, then let the mix dry all the way through before watering again. Most succulents go two to four weeks between waterings, and longer in winter.
A gritty cactus mix with plenty of pumice, perlite or coarse sand, in a pot with drainage holes. Standard potting soil on its own stays far too wet.
Most succulents are comfortable between 55 and 80F and need protection from frost. A cool, bright rest over winter suits many of them.
Use Succulent Root Supplement alongside your regular succulent fertilizer, especially after repotting, propagation, or a spell of overwatering, while new roots are forming.
Repot every two or three years in spring, shaking off old soil and trimming away dead roots. Wait a few days before watering so cut roots can callus.
Our fertilizer feeds your plant; Succulent Root Supplement feeds the root zone. It carries no nitrogen, phosphorus or potassium at all. Instead, three ingredients do the work: a kelp blend supplying natural growth compounds that drive root development, probiotics that improve nutrient availability in the soil and help crowd out the pathogens behind root rot, and plant-derived surfactants that help water and nutrients spread through fast-draining, often water-repellent succulent mixes. Use it alongside your succulent fertilizer rather than instead of it; the two do different jobs.
Mix Succulent Root Supplement into your watering at 1 teaspoon per quart, every 1 to 2 weeks in spring and summer and every 4 weeks in fall and winter. You can alternate it with your succulent fertilizer or use both in the same watering; they’re compatible, since the supplement adds kelp, probiotics and surfactants rather than more nutrient salts. It’s designed to work with all TPS succulent products, so pairing it with whichever TPS succulent feed you use, on the same schedule, is the simplest routine.
Succulent Root Supplement is most valuable when roots are being asked to do new work: right after repotting, when propagating cuttings or offsets, and while a new plant is establishing. Those are the moments when strong root development decides how quickly your plant settles and how well it takes up water and nutrients afterward. It also helps mature succulents sitting in old, gritty mixes that have lost their soil biology and become water-repellent, where the surfactants let water reach the roots instead of running straight through.
It supports prevention rather than a cure. The probiotics in Succulent Root Supplement help build a healthier, more active root zone and crowd out the pathogens behind rot, and the surfactants improve how water moves through the mix so it doesn’t stay saturated around the roots. Rot itself is driven mainly by overwatering, though, so the supplement works best alongside a gritty, fast-draining mix and careful watering that lets the soil dry between drinks. A plant already rotting needs the damaged roots removed and fresh dry mix first.
Yes. Cacti share the same fast-draining, low-nutrient root needs as other succulents, and the kelp, probiotics and surfactants in Succulent Root Supplement work the same way for them: supporting root strength and quicker establishment in gritty, quick-drying mixes. Barrel and columnar cacti that wobble in the pot after repotting, or that sit in a mix water runs straight through, are exactly what it’s made for. Use it at 1 teaspoon per quart alongside your regular cactus feed.
Root improvements happen below the soil, so the signs are indirect. Over weeks to a season on Succulent Root Supplement, look for faster establishment after repotting, cuttings and offsets that anchor sooner, plants that sit firmly in the pot instead of wobbling, and water that soaks into the mix rather than running straight through it. Better resilience against overwatering follows from that healthier root zone. It works as ongoing root support rather than a quick fix, so keep it in the routine.
