Creeping Borage problems — and how to fix them
Creeping Borage (Borago pygmaea) 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.
Powdery mildew
The bristly foliage is mildew-prone in dry-at-the-root, humid or crowded conditions. Keep soil moist, space plants, and remove affected leaves.
Short lifespan
Often short-lived and may behave almost biennially. Allow some self-seeding or take cuttings to maintain a presence.
Rot in wet, heavy soil
Lax sprawling stems and crown rot in waterlogged ground. Plant in free-draining soil and avoid winter wet.
Aphids
Cluster on tender shoot tips and flower stems. Hose off or use insecticidal soap; the flowers also attract aphid predators.
