Troubleshooting
Miller's Laelia problems — and how to fix them
Miller's Laelia (Cattleya milleri) 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.
Failure to flower
The most common complaint. This species is highly light-demanding and requires a distinct dry, cool rest in winter. Both conditions must be met simultaneously.
Root rot
Very susceptible to rot if the medium stays moist for more than a few days. Mount on cork or use an ultra-free-draining mix and a small pot.
Shrivelled pseudobulbs
Some shrivelling in late winter before new growth is normal and expected. Severe collapse indicates root damage — inspect and repot if necessary.
Scale insects
Check narrow pseudobulbs carefully. Treat with alcohol swabs and follow with horticultural oil.
Slug and snail damage
New growths are susceptible when the plant is moved outdoors in summer. Use slug pellets or copper tape around pots.
