Strobel's Masdevallia problems — and how to fix them
Strobel's Masdevallia (Masdevallia strobelii) 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.
Heat stress
The primary challenge in cultivation. Keep maximum summer temperatures below 22°C using a cool basement or dedicated grow cabinet with refrigerated air.
Root rot
Caused by a soggy, decomposed medium. Repot promptly into fresh bark mix when the medium breaks down, and ensure excellent drainage.
Spider mites
More prevalent in warm, dry conditions. Inspect leaves regularly and treat with insecticidal soap or neem oil spray if found.
Botrytis
Fungal rot encouraged by still, humid air. Maintain a constant low-speed fan to keep air moving around the foliage.
Bud blast
Rapid temperature swings or sudden humidity drops cause buds to shrivel before opening. Stabilise growing conditions during flowering.
