Acquired alongside Don Diego. Decision: repot same-day rather than let it settle – correct call for the species and the season.
Health assessment: dense deep-green foliage, brown tips cosmetic, caudex slim from greenhouse growing (normal). Overall good health.
Pot oversized; ruled out plastic inner pot and burying deeper. Settled on reduced fill volume with a shallow 2–3cm recess below the rim.
Final mix ~85% mineral: 1L zeolite + 1L keramzit + 1L perlite + ~0.5L DMP/Gardners substrate.
Bare-rooted dry, ~60 min total. Damage minimal – structural roots intact, only hair-root loss. One ant found, no treatment needed.
Leaf marks investigated: white flecks are mineral deposits (cosmetic); tan raised ovals failed the nail test – healed mechanical scarring, not scale.
