Plectranthus scutellarioides 'Black Dragon' problems — and how to fix them

Plectranthus scutellarioides 'Black Dragon' (Plectranthus scutellarioides 'Black Dragon') 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.

Faded or washed-out colour

Too much harsh direct sun bleaches the near-black tone, while too little light pales it; aim for bright filtered light or part shade.

Leggy, sparse growth

Skipping tip-pinching and letting flower spikes develop causes stretching; pinch regularly and remove blooms to keep the plant dense.

Wilting and crisping

Coleus collapses quickly when the soil dries out and crisps in dry, hot air; keep soil evenly moist and shelter from drying wind.

Spider mites and mealybugs

Dry indoor air encourages mites (stippling, fine webbing) and mealybugs; raise humidity, rinse foliage and treat with insecticidal soap.
