如何养护Venus Flytrap？
| 光照 | High – full sun outdoors; indoors strong white LED light of roughly 15,000–25,000 lux for about 14 h a day |
|---|---|
| CO₂ | Does not need a terrarium; wants open, moving air (humid stagnant air invites rot) |
| 水温 | 10°C – 27°C |
| 造景位置 | NOT a closed-terrarium plant: sealed humid air plus weak light rots it, and it also wants a cool winter rest. Open terrarium: short-term only, under very strong light with good airflow, planted so you can lift it out for winter rest. A sunny windowsill or outdoor pot is where it does best. |
| 生长速度 | Slow |
| 养护难度 | Moderate |
| 科属 | Droseraceae |
如何修剪与繁殖Venus Flytrap？
Snip off blackened traps and dead leaves. Flower stalks can be removed to save the plant's energy, or left if you want seed. Do not set off traps for fun – each closes only a handful of times before it dies. Repot yearly in spring into fresh media.
Venus Flytrap有哪些常见问题？
New traps black or not forming from mineral build-up (tap water, old media); pale floppy leaves and green traps from low light; rot and collapse after a year indoors from humid still air or no winter rest; aphids, spider mites, grey mould.
如何解决Venus Flytrap的常见问题？
Water only with rain, distilled or RO water (ICPS: under 90 ppm dissolved solids); stand the pot in a tray of it while growing, damp rather than sodden in winter. Pot in sphagnum, pure peat or 1:1 peat and sand; ICPS advises against perlite; never ordinary or fertilised compost. NEVER fertilise the soil – it can go months without prey. Give a cool winter rest (RHS: keep above 10°C); ICPS says indoor plants can skip dormancy, but the rest is the safer default.
