Troubleshooting
Boke's Button Cactus problems — and how to fix them
Boke's Button Cactus (Epithelantha bokei) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from any excess moisture
Minuscule root systems mean even small amounts of overwatering can cause collapse. Err strongly on the side of under-watering at all times.
Legal sourcing issues
This is a federally threatened species in the US. Always source from reputable nurseries that can certify seed-grown or nursery-propagated specimens — never take from the wild.
Difficulty distinguishing from E. micromeris
The two species are very similar; E. bokei is typically smaller and found only around Big Bend. Mislabelling in the trade is common.
Extremely slow growth discouraging beginners
Growth is often imperceptible year to year. This is entirely normal. Focus on maintaining correct care conditions rather than expecting visible changes.
Mealybugs
Very hard to spot on such a tiny, densely-spined plant. Use a magnifying glass to inspect and a fine-tipped swab with isopropyl alcohol to treat.
