Monstera Root Supplement

Monstera root supplement that supports recovery from repotting and root stress. Healthy roots power the big, fenestrated leaves monsteras are known for.
Use it during repotting, transplanting, propagation, or other periods of root stress for a simple way to support recovery and new root development.
Why You'll Love It
- Strong Roots Supports recovery from repotting and root stress on established monsteras.
- Healthier Soil For pots where water runs past the roots instead of soaking in.
- Healthy Foliage Healthy roots are what power big, fenestrated monstera leaves.

Root Supplement for monsteras with sea kelp, soil probiotics, and plant-based surfactants — made to build the root system behind big, well-split new leaves. This is a supplement, not a fertilizer: it works alongside your monstera food, with probiotics improving nutrient uptake and surfactants helping water spread through the whole pot instead of channeling past a dry root ball.
How to Use Monstera Root Supplement
| Method | Amount | How Often |
|---|---|---|
| Watering can (spring & summer) | 1 tsp per quart (32 oz) of water | Apply every 1-2 weeks |
| Watering can (fall & winter) | Same dilution | Apply every 4 weeks |
Mix into your normal watering — no separate feeding routine needed. Designed to pair with all TPS monstera products, not replace them.
What's Inside
Four ingredients, all working below the soil line. Sea kelp supplies natural growth-promoting compounds that support new root development — and with monsteras, root capacity is what decides whether the next leaf comes out bigger and more split than the last, or the same size. A 10% probiotic houseplant blend adds beneficial microbes that improve nutrient availability in the pot and help crowd out the rot organisms that take hold in soil kept too wet.
Plant-derived surfactants fix a common container problem: once a chunky aroid mix dries out, water channels down the sides and out the drainage holes without wetting the root ball. Surfactants break that surface tension so water and nutrients spread evenly, and plant-derived fulvic acid helps carry minerals into the roots — including aerial roots you've directed back into the pot. There's no NPK here by design; it supplements your fertilizer rather than competing with it.
Made For
Monstera deliciosa (Swiss cheese plant), Monstera adansonii, Thai Constellation and other variegated varieties, and Monstera peru — from young plants to large climbing specimens on moss poles — especially monsteras being repotted, propagated, or recovering from root stress.
Problems It Solves
- New leaves coming in small with few or no splits
- Water running out the drainage holes without soaking the root ball
- Slow recovery after repotting or propagation
- A monstera pushing aerial roots but stalled below the soil
FAQs
How often should I use root supplement on a monstera?
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. It's designed to work alongside your monstera fertilizer, so keep your regular feeding schedule and simply add this to the rotation.
What should I do with my monstera's aerial roots?
You have options: leave them, train them onto a moss pole, or redirect them back into the soil — where they'll take up water and nutrients like regular roots. Redirecting them into the pot means they benefit from watering and this supplement too. Don't cut healthy aerial roots off; they're part of how a climbing monstera supports bigger leaves as it matures.
Why are my monstera's new leaves small with no splits?
Splits (fenestrations) come with maturity, light, and support — a young plant won't split no matter what you feed it, and low light keeps leaves small at any age. Bright indirect light and something to climb matter most. Where roots come in: each new leaf draws on root capacity, so a stronger root system supports the size progression once light and maturity are there.
Is this a fertilizer? Do I still need monstera food?
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 absorb water and nutrients, but the plant still needs actual nutrition from a fertilizer. The two work together: this makes the root system better at using what your monstera food delivers.
Can I use this on monstera cuttings and propagations?
Yes — freshly potted propagations are the classic use case. Once a cutting has roots and goes into soil, it's running on a small, new root system, and how fast that establishes determines how fast the plant takes off. Start the supplement with your first regular watering. For cuttings still in water, wait until they're potted in soil, since the probiotics are a soil blend.
When will I see results?
Root progress shows above the soil on a delay. Within 2-4 weeks of regular use, expect a plant that holds steady and resumes pushing growth rather than sulking. New leaves reflect it next: in the growing season, a healthy monstera unfurls a new leaf every 4-6 weeks, and stronger roots show up as steadier production and better size progression leaf over leaf.
