About Peyote

Lophophora williamsii · also called Peyote, Mescal Button · houseplant

Lophophora williamsii is a small, spineless, blue-green desert cactus from the Chihuahuan Desert, forming low domed buttons with woolly tufts and tiny pink flowers. It is famous for containing the hallucinogenic alkaloid mescaline. A true xerophyte, it demands intense light, very gritty soil, and minimal water, growing extremely slowly. Note: cultivation is legally restricted in many regions.

Growth habit: Small, slow-growing, solitary or clustering button cactus; a flattened blue-green dome divided into ribs and tubercles with woolly areoles, set above a stout subterranean taproot.

Watch for — Pale, elongated, distorted growth: Too little light. Give the brightest possible direct sun to restore the compact button shape.

What fertiliser peyote actually wants — and why

Peyote 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 peyote: 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 peyote, 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 peyote:

Feed lightly only during the growing season, around once a month or less, with a dilute low-nitrogen cactus fertiliser. Because it grows extremely slowly, it needs very little feeding; over-fertilising forces soft, rot-prone growth. No feeding in winter dormancy. Keep that to once a month 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 peyote 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 peyote

Quarter to half strength at most for peyote. 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 peyote first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the peyote watering schedule.

Signs you are over-feeding peyote

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for peyote:

Signs you are under-feeding peyote

If the symptoms point at watering, light or roots rather than nutrition, the full peyote 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 peyote until it drains clear, and refresh the gritty mix every 2-3 years.

Organic vs synthetic feeds for peyote

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 strength of feed for peyote?

Quarter to half strength at most for peyote. Succulents take up very little, and a strong dose burns the fine roots before the plant can use it.

What does over-feeding peyote 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 peyote 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 peyote?

Feed lightly enough and you rarely need to flush, but once a year run plain water through the pot of peyote until it drains clear, and refresh the gritty mix every 2-3 years.
