Troubleshooting
Odontoglossum crispum problems — and how to fix them
Odontoglossum crispum (Odontoglossum crispum) 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 intolerance
Warm nights are this orchid's chief killer, causing collapse, bud blast and rot. Sustained temperatures above the mid-20s°C are poorly tolerated; cool nights are non-negotiable.
Bud blast
Buds yellow and drop before opening when humidity drops or temperatures swing too widely. Maintain steady high humidity and avoid sudden environmental changes while spiking.
Root loss in stale mix
Fine roots die quickly in decomposed, sour bark. Repot into fresh, open medium every year or so and keep it airy rather than soggy.
Pseudobulb shrivelling
Pleated, soft pseudobulbs mean the plant is dehydrated, usually from dead roots or under-humidity rather than too little watering at the pot. Address roots and raise humidity.
