About Pickle Plant
Delosperma echinatum · also called Pickle Plant, Pickle Cactus · houseplant
Delosperma echinatum is a quirky South African succulent grown for its plump, pickle-shaped leaves covered in soft white bristles rather than its modest yellow-white flowers. Slow-growing and compact, it makes an entertaining houseplant for bright windowsills. Needs sharply drained soil, infrequent watering, and strong light to maintain its characteristic dense, spiny appearance.
Preferred mix: Gritty cactus and succulent mix
Watch for — Root rot from overwatering: The most common problem in cultivation. Stems become mushy at the base when roots have rotted. Allow soil to dry completely between waterings and ensure the pot has drainage holes.
Why pickle plant needs this mix
Pickle 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.
- Pickle 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 pickle 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 pickle 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 pickle 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 pickle plant?
pH is not a concern for pickle 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 pickle 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 pickle 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 pickle plant covers the timing and technique step by step.
