About Mulanje Cycad
Encephalartos gratus · also called Mulanje Cycad, Grateful Cycad · tropical
Mulanje Cycad is a medium-sized cycad from the highlands of Malawi and Mozambique, named after Mount Mulanje. It is notable for its attractive, glossy bright-green fronds and relatively faster growth compared to southern African relatives. It tolerates moderate humidity and seasonal rainfall. A prized collector's specimen for tropical gardens, conservatories, and large heated indoor spaces.
Preferred mix: Loamy, gritty, free-draining mix
Watch for — Interveinal chlorosis on new fronds: Yellowing between the veins of newly emerging leaflets indicates manganese or iron deficiency, common in alkaline or waterlogged substrates. Apply a chelated iron/manganese foliar spray and ensure pH remains at 5.5–6.5. Improve drainage to restore nutrient uptake.
Why mulanje cycad needs this mix
Mulanje Cycad 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.
- Mulanje Cycad 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 mulanje cycad 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 mulanje cycad; 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 mulanje cycad 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 mulanje cycad?
pH is not a concern for mulanje cycad — 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 mulanje cycad 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 mulanje cycad 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 mulanje cycad covers the timing and technique step by step.
