Mountain African Daisy problems — and how to fix them
Mountain African Daisy (Osteospermum jucundum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Aphid infestations on new growth
Aphid colonies gather on young shoot tips and buds, causing distorted growth and sticky honeydew residue. Blast off with water or apply insecticidal soap; encourage natural predators such as ladybirds.
Verticillium wilt
In heavy or poorly drained soils this soil-borne fungus causes sudden wilting and browning of stems. There is no cure — remove affected plants, do not replant Osteospermum in the same spot, and improve drainage.
