Agapanthus 'Headbourne Hybrids' problems — and how to fix them
Agapanthus 'Headbourne Hybrids' (Agapanthus 'Headbourne Hybrids') 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.
Few or no flowers
Usually too much shade, an over-rich nitrogen feed, or a recently divided clump. Give full sun, switch to high-potash feed, and leave roots slightly congested.
Winter crown rot
Wet, cold soil rots dormant crowns. Improve drainage with grit, keep dry over winter, and mulch the crown in colder areas to buffer frost.
Agapanthus gall midge
Larvae feed inside buds, causing them to discolour, deform and fail to open. Remove and destroy affected buds promptly to reduce the next generation.
Leaf yellowing
Often natural autumn dieback in this deciduous strain, but persistent yellowing in summer can signal waterlogging or nutrient shortage; check drainage and feeding.
