Acharagma aguirreanum

Acharagma aguirreanum identity and care summary

Acharagma aguirreanum is an Acharagma with a small tubercled body. A small globose to short-columnar body, tubercle rather than rib pattern, areoles and spines, flowers, fruit, seeds and documented provenance should be evaluated together. Identity should not be settled from a sales label or one photograph; tubercles, areoles, spines, flowers, fruit, seeds and documented provenance should be evaluated together.1

Root zone, medium and watering

Use a very fast-draining mix dominated by coarse sand, pumice and other mineral particles that does not retain prolonged moisture around the roots. Do not use a fixed-day calendar; water in a controlled cycle only after the mineral mix and root zone have dried throughout, and extend the interval substantially in cool or low-light periods. A dry-looking surface is insufficient; inspect the root zone as well. Leave no standing water after irrigation. After repotting, allow injured roots time to dry and callus.

Do not test low temperature with wet roots during a cool rest. Evaluate wrinkling, soft tissue, colour change and root odour together; attempts to force rapid growth in a continuously wet organic medium increase rot risk.

Light, temperature and observation

The live direct_sun operational enum is preserved; acclimate over several weeks and monitor airflow and root-zone heat behind glass. The operational enum is not a laboratory light threshold; airflow, heat behind glass, season and previous cultivation conditions alter the outcome. Increase light over several weeks and do not test cold tolerance with a hot or wet root zone.

Kew maintains three homotypic historical combinations: Escobaria aguirreana, Gymnocactus aguirreanus and Thelocactus aguirreanus. They are not separate accepted-species routes. Names of other accepted Acharagma species, trade labels or identifications based only on flower colour are not added to this canonical synonym set.

Safety and conservation

The live safe field is preserved as an operational carry-forward; do not ingest the plant and use basic physical precautions for spines. The global conservation field is CR.2 The live EN value is corrected to the official global IUCN CR. Critically Endangered concerns wild populations, not commercial inventory. Prefer documented legal nursery propagation and do not encourage wild collection.

Light

Direct Sun

The live `direct_sun` operational enum is preserved; acclimate over several weeks and monitor airflow and root-zone heat behind glass.

Watering

12-40 Days

Do not use a fixed-day calendar; water in a controlled cycle only after the mineral mix and root zone have dried throughout, and extend the interval substantially in cool or low-light periods.

Soil

Very well-draining, gritty cactus mix with high mineral content

Use a very fast-draining mix dominated by coarse sand, pumice and other mineral particles that does not retain prolonged moisture around the roots.

Safety

Pet Friendly

The live `safe` field is preserved as an operational carry-forward; do not ingest the plant and use basic physical precautions for spines.

Difficulty

Hard

Live operational care class: hard.

Frequently Asked Questions

What is the accepted name?
Acharagma aguirreanum (Glass & R.A.Foster) Glass
What is its native range?
Coahuila, Mexico
How often is it watered?
There is no fixed interval; water after the mineral mix and root zone have dried throughout.
What medium is suitable?
Use a very fast-draining mix dominated by coarse sand, pumice and other mineral particles that does not retain prolonged moisture around the roots.
What light is suitable?
The live `direct_sun` operational enum is preserved; acclimate over several weeks and monitor airflow and root-zone heat behind glass.
Are synonyms separate species routes?
No; they are nomenclatural names related to the same accepted species in the maintained backbone.
Does a product photograph prove identity?
No; tubercles, areoles, spines, flowers, fruit, seeds and provenance must be evaluated together.
Is conservation status based on retail stock?
No; global conservation status concerns evidence about wild populations, not commercial inventory.
