Troubleshooting
Cattleya walkeriana problems — and how to fix them
Cattleya walkeriana (Cattleya walkeriana) 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.
No flowers
Usually too little light. Cattleyas need high light to bloom; move to the brightest spot short of scorching, and provide the drier rest after growth matures to help set buds.
Black or soft rot in the crown
Water trapped in the growth point, plus poor airflow, causes bacterial and fungal rot. Water in the morning, keep water out of the new growth, and ensure good ventilation.
Shrivelled or limp pseudobulbs
Dehydration from dead roots or excessive dryness. Inspect the roots — repot if rotted — raise humidity, and adjust watering so the bulbs stay plump.
Sunburn
Bleached or blackened scorched patches appear when a plant is moved into intense direct sun too quickly. Increase light gradually and shade against harsh midday rays.
