Troubleshooting
Antigonon leptopus problems — and how to fix them
Antigonon leptopus (Antigonon leptopus) 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.
Invasive spread
In warm climates it spreads aggressively by seed and tubers and is a recognised weed in parts of the tropics. Keep it contained, deadhead, and never let it escape into wild areas.
Frost dieback
Top growth is killed by frost; in marginal areas the tuberous roots may resprout in spring. Mulch the crown over winter and cut away dead growth as new shoots appear.
Reverts to foliage with rich feeding
Over-fertile soil and heavy feeding give leaves at the expense of flowers. Grow in leaner soil and feed sparingly with a high-potash fertiliser.
Aphids
Soft new growth attracts aphids that cause distortion and sticky honeydew. Hose off colonies and encourage natural predators rather than reaching for sprays.
