Troubleshooting
Sobralia macrantha problems — and how to fix them
Sobralia macrantha (Sobralia macrantha) 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
Too little light or premature division prevents blooming. Give bright Cattleya-level light and leave clumps undisturbed to build strong canes.
Resentment of repotting
Disturbing the roots sets the plant back for a year or more. Repot only when essential, in spring as new growth starts, into a large stable pot.
Fleeting flowers
Individual flowers last only a day, which surprises new growers. This is normal; enjoy the long succession of blooms rather than expecting lasting ones.
Spider mites and scale
Dry air invites mites; the canes can harbour scale. Maintain humidity and inspect cane bases, treating early with horticultural oil or insecticidal soap.
