Troubleshooting
Garlic Bignone problems — and how to fix them
Garlic Bignone (Cydista aequinoctialis) 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.
Poor or absent flowering
Insufficient sun is the most common cause. Ensure the plant receives all-day full sun. Also avoid pruning at the wrong time — trim hard immediately after each flowering flush, not during bud development.
Frost damage
Even brief exposure to freezing temperatures causes tip dieback and leaf drop. In USDA zone 10 and above, the plant is evergreen year-round. In borderline zones, protect with horticultural fleece or bring container specimens indoors.
Spider mites in dry conditions
Under glass or in hot, dry weather, spider mites can cause fine stippling on leaves. Increase humidity around the plant, wash foliage regularly, and apply a miticide or predatory mites if infestation is severe.
