Troubleshooting
Purple Vygie problems — and how to fix them
Purple Vygie (Drosanthemum hispidum) 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.
Rot in cold, wet conditions
Wet cold — not dry cold — is the main threat. In climates with cold, wet winters, grow in containers that can be brought under frost-free glass, or ensure planting sites have near-perfect drainage. Wet soggy crowns rot rapidly below 4°C.
Aphids on new growth
Soft spring shoots attract aphid colonies. Treat early with insecticidal soap or a jet of water. The hairy stems can shelter colonies from contact sprays, so ensure thorough coverage including stem undersides.
Leggy, non-flowering growth
Plants grown in insufficient light become straggly and bloom poorly. Trim back after flowering to encourage compact regrowth, and move containers to the sunniest available position. Replace plants that have become too woody after 3–4 years.
