About Curio Ficoides
Curio ficoides · also called ice plant, blue chalk sticks · houseplant
Curio ficoides (formerly Senecio ficoides), a South African succulent, bears upright, fingerlike blue-grey leaves dusted with a chalky waxy bloom that reflects sun and conserves water. Drought-tough and architectural, it thrives on neglect in bright light and gritty soil, spreading into a low blue-toned mound. Like other Curio it is toxic to pets, so site it out of their reach.
Preferred mix: Gritty, fast-draining cactus/succulent mix
Watch for — Soft, mushy, rotting stems: Overwatering or poor drainage — the most common cause of death. Let the soil dry fully between soakings and use a gritty, free-draining mix.
Why curio ficoides needs this mix
Curio Ficoides 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.
- Curio Ficoides 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 curio ficoides 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 curio ficoides; 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 curio ficoides 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 curio ficoides?
pH is not a concern for curio ficoides — 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 curio ficoides 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 curio ficoides 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 curio ficoides covers the timing and technique step by step.
