Ipomoea batatas 'Blackie' problems — and how to fix them
Ipomoea batatas 'Blackie' (Ipomoea batatas 'Blackie') 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.
Foliage turning green, not black
Caused by insufficient light. Move to full sun to maintain the deep purple-black leaf colour.
Rapid wilting in containers
It is very thirsty and dries out fast in pots and baskets in heat. Water frequently and use larger or self-watering containers in summer.
Sweet potato weevil and beetle damage
Flea beetles, weevils, and golden tortoise beetles chew the leaves. Inspect regularly and treat damaging infestations; minor chewing is mostly cosmetic.
