About Teddy Bear Vine
Cyanotis kewensis · also called Teddy Bear Vine, Teddy Bear Plant · houseplant
A distinctive trailing houseplant from southern India with teardrop-shaped fleshy leaves clothed in dense chocolate-brown hairs, giving the plant its irresistible teddy-bear texture. Suitable for hanging baskets in bright indirect light, it requires well-draining soil, moderate watering, and grows actively year-round without a true dormant period.
Preferred mix: Well-draining houseplant or succulent mix
Watch for — Stem rot from wet foliage: The dense brown hairs hold moisture against the stems if watered overhead or placed in overly humid conditions. Water at soil level only, and ensure good air circulation around the plant. Remove any rotted sections immediately with sterile scissors.
Why teddy bear vine needs this mix
Teddy Bear Vine stores water in its leaves and stems, so it wants a free-draining, gritty mix that dries out fully between waterings — not a moisture-holding one.
- Teddy Bear Vine carries its own water supply in its thick tissue, so the soil's job is to drain fast and then get out of the way.
- Its roots are adapted to short wet spells followed by long dry ones — a mix that stays damp removes the dry phase they depend on.
- A gritty mix also keeps the plant compact and well-coloured rather than soft, leggy and prone to collapse.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons teddy bear vine struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Standard potting compost on its own stays wet far too long for teddy bear vine; the lower leaves and stem base go soft and translucent first.
- Big plastic pots full of dense mix hold a wet core long after the surface looks dry — that hidden wet zone is where rot starts.
- Anything sold as "moisture control" is the opposite of what this plant wants.
Treating teddy bear vine like a leafy houseplant and using plain compost. It needs at least half its volume as grit, perlite or pumice to survive long term.
pH — does it matter for teddy bear vine?
pH is not a concern for teddy bear vine — anything from mildly acidic to neutral (6.0-7.0) works. Get the drainage right and pH looks after itself.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good bagged "cactus and succulent" mix works for teddy bear vine if you add roughly 30-50% extra perlite or grit. Mixing your own from the ratio above gives you full control of how fast it dries.
Drainage and the pot
Use a pot with a drainage hole and empty the saucer within minutes of watering. Terracotta is more forgiving than glazed or plastic because it dries the rootball faster.
This mix decomposes slowly, so teddy bear vine only needs repotting every 2-3 years — mainly to refresh the grit and check the roots are firm and pale. When the time comes, our repotting guide for teddy bear vine covers the timing and technique step by step.
