Apache beggarticks problems — and how to fix them
Apache beggarticks (Bidens ferulifolia) 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.
Aphid colonies
Dense populations of green or black aphids cluster on soft new growth, causing distortion and sticky honeydew. Blast off with water, then apply insecticidal soap spray. Encourage natural predators such as lacewings and ladybirds.
Legginess in shade
Stems elongate rapidly and flower production drops when light is insufficient. Relocate to full sun and cut leggy stems back by one-third to restore compact form; new flowering shoots emerge within 2 weeks.
Root rot in waterlogged containers
Yellowing leaves followed by sudden wilt indicate root rot. Remove from pot, trim rotted (brown, mushy) roots, allow to dry briefly, and repot in fresh, well-draining compost. Ensure containers have adequate drainage holes.
