Forked Sundew problems — and how to fix them
Forked Sundew (Drosera binata) 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.
Dormancy failure (plant dies without re-sprouting)
D. binata must have a winter rest period with cool temperatures and reduced watering; plants kept too warm and wet year-round exhaust their energy reserves and fail to re-emerge. Allow leaves to die back naturally in autumn, reduce the water tray to near-empty, and keep cool (4–12°C) for 8–12 weeks.
Aphids on flower scapes
Aphids cluster on elongating flower scapes in spring; remove by wiping with a damp cloth or a cotton bud dipped in isopropyl alcohol — avoid systemic insecticides, which can harm carnivorous plants.
Root rot from compacted or alkaline medium
Over time, peat compacts and mineral deposits from impure water raise the soil pH; repot every 2 years into fresh medium and flush thoroughly with distilled or rainwater to restore acidity and drainage.
