Agapanthus inapertus subsp. pendulus problems — and how to fix them
Agapanthus inapertus subsp. pendulus (Agapanthus inapertus subsp. pendulus) 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.
Floppy or leaning stems
Shade and over-rich soil produce weak, tall scapes that lean. Site in full sun and avoid heavy nitrogen feeding so stems stay self-supporting.
Poor flowering after division
Recently split clumps sulk for a year or more. Leave roots undisturbed and slightly congested to encourage free flowering.
Winter crown rot
Cold, waterlogged soil rots the dormant crown. Improve drainage with grit and keep the crown dry through winter, mulching in colder gardens.
Agapanthus gall midge
Larvae develop inside buds, deforming and browning them before they open. Remove and destroy affected buds to reduce the pest.
