About Ghost Plant
Graptopetalum paraguayense · also called Ghost plant, Mother of pearl plant · houseplant
The ghost plant is an easy, trailing Mexican succulent prized for ghostly pastel rosettes dusted in chalky white farina that blush pink, peach and lilac in strong light. Its one defining need is sharp drainage and a long dry-out between drinks: it stores water in its leaves and rots fast if the roots ever stay wet.
Preferred mix: Gritty cactus and succulent mix
Watch for — Overwatering and root rot: By far the commonest killer. The fine roots and fleshy leaves hold water, so soggy compost quickly turns stems mushy and translucent. Always let the mix dry out fully, use gritty soil and a draining pot, and water far less in winter.
Why ghost plant needs this mix
Ghost Plant 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.
- Ghost Plant 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 ghost plant 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 ghost plant; 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 ghost plant 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 ghost plant?
pH is not a concern for ghost plant — 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 ghost plant 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 ghost plant 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 ghost plant covers the timing and technique step by step.
