Many-Flowered Epidendrum problems — and how to fix them
Many-Flowered Epidendrum (Epidendrum polyanthum) 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.
Leggy canes from insufficient light
In low light the upright canes become elongated and floppy with sparse leaves, and flowering is poor. Move to a brighter location — a south or west window — or supplement with a grow light to provide at least 2,500 footcandles.
Mealybugs in leaf axils
Mealybugs commonly hide in the tight leaf axils along the cane where they are hard to spot until populations are large. Inspect with a magnifying glass monthly; treat with isopropyl alcohol swabs or a systemic insecticide if colonies spread.
Root rot from poor drainage
Waterlogged bark medium causes the fibrous roots to blacken and collapse. Always use a freely draining mix in a pot with adequate holes, and check that the medium fully dries slightly between waterings rather than remaining saturated.
