Troubleshooting
Buttonwood Bonsai problems — and how to fix them
Buttonwood Bonsai (Conocarpus erectus) 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.
Cold damage
A frost-tender tropical; temperatures near or below 10°C cause dieback. Bring it into warmth well before any chill and never expose it to frost.
Insufficient light
Without intense sun it grows weak, sparse, and prone to dieback. Give it the strongest light available year-round, indoors or out.
Spider mites and scale
Heat and dry indoor air favour mites; scale lurks on bark. Monitor closely and treat with horticultural oil or insecticidal soap.
Branch dieback after hard pruning
It can be slow and unpredictable to bud back on old wood. Make significant cuts only on a vigorous tree in warm conditions, and avoid removing all foliage from a branch.
