Troubleshooting
Orange Prosthechea problems — and how to fix them
Orange Prosthechea (Prosthechea vitellina) 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.
Bud blast from heat
Temperatures above 24°C during bud development cause flowers to abort before opening.
Root rot
Overwatering or a degraded bark mix that retains too much moisture leads to root blackening.
Pseudobulb yellowing
Excessive light or heat causes pseudobulbs to yellow and lose stored nutrients.
Scale
Armoured scale insects attach to pseudobulbs and leaf undersides, causing stippling and dieback.
Slow re-establishment after repotting
Prosthechea vitellina is sensitive to root disturbance; disturbed roots take several months to regrow.
