Troubleshooting
White-red Trichocentrum problems — and how to fix them
White-red Trichocentrum (Trichocentrum albococcineum) 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.
Botrytis on flowers
High humidity without airflow encourages grey mould to develop on the white petals.
Root dehydration on mounts
Mounted plants in dry indoor air require very frequent misting to prevent root desiccation.
Mealybugs
Mealybugs conceal themselves between tightly packed pseudobulbs and are difficult to eradicate once established.
Overwatering in small pots
Small pots retain moisture longer than expected; watering on a fixed schedule rather than checking dryness causes rot.
Failure to flower
Insufficient light intensity, particularly in winter, prevents flower bud initiation in this species.
