Troubleshooting
Sander's Maxillaria problems — and how to fix them
Sander's Maxillaria (Maxillaria sanderiana) 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 in warm conditions
Cool-growing and very susceptible to root and crown rot if temperatures exceed 22°C in summer. Ensure cool, airy conditions at all times.
Fungal crown rot
Water pooling in new growths causes rapid rot. Always water at the base and ensure good air movement around the crown.
Brown leaf tips
Usually caused by low humidity or fluoride/chlorine in tap water. Maintain humidity above 65% and use soft or rainwater.
Scale insects
Check regularly, especially on pseudobulbs. Treat early with rubbing alcohol or horticultural oil.
Failure to flower
Needs consistent cool temperatures (especially nights below 16°C) and high humidity. Warm or dry conditions result in vegetative growth only.
