About Hikuri
Lophophora diffusa · also called False Peyote, Hikuri · houseplant
Lophophora diffusa, called false peyote or hikuri, is a small spineless button cactus endemic to a tiny area of Querétaro, Mexico. Yellow-green and softer-ribbed than true peyote, it contains mainly the sedative alkaloid pellotine with only traces of mescaline. A slow-growing xerophyte, it needs bright light, very gritty soil, and minimal water; wild populations are vulnerable.
Growth habit: Small, slow-growing, solitary to slowly clustering button cactus; a flattened yellow-green dome with low, soft, indistinct ribs and woolly areoles above a stout taproot.
Watch for — Etiolated, pale, soft growth: Insufficient light. Provide the brightest direct sun possible to restore compact form and colour.
What fertiliser hikuri actually wants — and why
Hikuri 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 hikuri: 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 hikuri, 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 hikuri:
Feed only lightly in the growing season, about monthly or less, with a dilute low-nitrogen cactus feed. Its very slow growth means minimal feeding is needed; excess nitrogen produces soft, rot-prone tissue. Do not feed during winter dormancy. Keep that to monthly 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 hikuri 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 hikuri
Quarter to half strength at most for hikuri. 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 hikuri first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the hikuri watering schedule.
Signs you are over-feeding hikuri
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for hikuri:
- 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 hikuri
- 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 hikuri 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 hikuri until it drains clear, and refresh the gritty mix every 2-3 years.
Organic vs synthetic feeds for hikuri
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 hikuri look like?
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. Feeding hikuri 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 hikuri?
Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of hikuri until it drains clear, and refresh the gritty mix every 2-3 years.
