Blue-flowered Torch problems — and how to fix them
Blue-flowered Torch (Wallisia lindeniana) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Mealybugs in leaf axils
White cottony clusters accumulate where the leaves meet the central stem; dab with a cotton swab soaked in isopropyl alcohol and follow up with a diluted insecticidal soap spray, repeating weekly for a month.
Failure to flower
Most commonly caused by insufficient light or too-cool temperatures; move to a brighter position and, if the plant is mature and still dormant, enclose it loosely in a bag with a ripe apple for several days — the ethylene gas produced can stimulate blooming.
