Tracked shipping

CANNA Rhizotonic is the CANNA option for root transitions: cuttings, repotting, stress recovery and young plants. It makes sense when the root system needs attention before extra leaf feeding does.

Transition and recovery care

Use it after potting, moving a cutting into a new medium, or bringing a stressed plant back into stable conditions. It fits many growing methods because the focus is root response across several base-feed systems.

Support around the nutrient plan

Rhizotonic does not replace fertilizer. Pair it with Start for young plants or with the correct CANNA base nutrient once normal growth resumes.

CANNA Rhizotonic fits soil, coco, hydro and semi-hydro plants that need help establishing fresh roots. Reserved for cuttings after rooting, plants moved into a new medium and specimens recovering from shipping or repotting.

Pair with a gentle nutrient once the plant begins taking up water normally.

What's inside:

NPK Ratio: No NPK / Atlantic seaweed (Ascophyllum nodosum) root stimulant
Nutrient basis: Seaweed root biostimulant

CANNA Rhizotonic is a seaweed-based root stimulator for establishment, repotting and recovery phases. It belongs around root activity, not in the main NPK-feeding role.

Its active ingredient is Atlantic seaweed, Ascophyllum nodosum, with no NPK ratio to compare against fertilizers. Use it to support fresh root response while the base feed is chosen for the medium.

How to use it

Use CANNA Rhizotonic around 4 ml/L for rooted cuttings, repotting and recovery, then reduce once new growth is steady. It can be watered into the substrate or used as a foliar spray when the plant is suitable for spraying.

Apply early in the growth stage or after stress, then stop once that support is no longer needed.

➜ A few notes before measuring, mixing or applying :

Keep foliar use light and spray out of direct sun to reduce leaf marks. Correct compacted, cold or constantly wet substrate before expecting a root additive to help.

Measure with a clean syringe or cup to keep the concentrate uncontaminated.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

I received perfectly heathy and absolutely beautiful plants, even bigger than expected. The delivery within Europe was really fast. I think Foliage Factory has one of the best plant web shops in the internet. It‘s just great to get so much informations about the plants. I will definitely order again :)
