About Maughan's Cone Plant
Conophytum maughanii · also called Maughan's Cone Plant, Maughan Conophytum · houseplant
Conophytum maughanii is a rare South African mesemb prized by collectors for its small, elegantly patterned rounded bodies that form tight clusters. It produces delicate flowers in autumn. Among the more specialist Conophytum, it demands meticulous watering discipline, extremely gritty soil, and plentiful direct sun to complete its annual dormancy-and-growth cycle successfully.
Growth habit: Compact clump-forming stemless succulent with small, rounded to slightly flattened paired bodies
What fertiliser maughan's cone plant actually wants — and why
Maughan's Cone Plant is a light-feeding succulent — a gentle, low-nitrogen feed a few times in growth keeps it plump without forcing the weak, stretched growth over-feeding causes.
A cactus and succulent formula or a diluted balanced feed with modest, even numbers. Avoid high-nitrogen plant foods — they make a succulent etiolate and grow soft, fracture-prone tissue.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for maughan's cone plant: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed maughan's cone plant, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For maughan's cone plant:
Feed once at the very start of autumn growth with a quarter-strength low-nitrogen cactus fertiliser. Do not fertilise during dormancy or in the first season after division. Excess nutrients promote bloating and reduce drought tolerance. Keep that to sparingly through the growing season between spring through early autumn (roughly March to September) and stop entirely once growth slows for winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when maughan's cone plant is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for maughan's cone plant
Quarter to half strength at most for maughan's cone plant. Succulents take up very little, and a strong dose burns the fine roots before the plant can use it.
Feeding always goes onto already-damp soil, never dry roots — water maughan's cone plant first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the maughan's cone plant watering schedule.
Signs you are over-feeding maughan's cone plant
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for maughan's cone plant:
- Stretched, leggy, pale growth with widely spaced leaves.
- A white salt crust on the soil or around the pot rim.
- Brown, crisped leaf tips and edges.
- Soft, mushy tissue at the base — over-feeding plus damp soil rots it.
Signs you are under-feeding maughan's cone plant
- Uncommon — succulents tolerate lean conditions well.
- Very slow growth and dull, faded colour over a long period.
- Older leaves shed faster than new ones replace them in a tired old mix.
If the symptoms point at watering, light or roots rather than nutrition, the full maughan's cone plant care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of maughan's cone plant until it drains clear, and refresh the gritty mix every 2-3 years.
Organic vs synthetic feeds for maughan's cone plant
Organic options
A heavily diluted seaweed or worm-casting feed once or twice in summer. UK: a drop of Westland seaweed feed; US: quarter-strength Espoma Cactus! or Dr. Earth liquid. Fresh free-draining mix matters more than any feed.
Synthetic / liquid feeds
A dedicated cactus/succulent liquid at quarter to half strength — UK: Baby Bio Cacti & Succulent Drip Feeders or Westland; US: Miracle-Gro Succulent Plant Food or Schultz Cactus Plus.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding maughan's cone plant look like?

Soft, mushy tissue at the base — over-feeding plus damp soil rots it. Feeding maughan's cone plant like a leafy houseplant is the classic error — it produces a flush of pale, stretched, floppy growth that never firms up and is prone to rot at the base.
Should I flush the soil of maughan's cone plant?
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of maughan's cone plant until it drains clear, and refresh the gritty mix every 2-3 years.
