| CO₂ | Likes humidity above normal room levels (no figure in sources) |
| 水温 | 10°C – 35°C |
| 配置 | SUITS closed and open terrariums – among the best terrarium carnivores because it needs no winter dormancy. In a closed tank give strong light and a little ventilation to limit mould. Note: temperate sundews (e.g. D. rotundifolia, D. filiformis, some D. binata forms) DO need a cold winter and are poor closed-terrarium plants. |

| 難易度 | Easy |

Cape Sundew (Drosera)のトリミングや増やし方は？
Remove dead lower leaves as the rosette grows. Cut flower stalks after blooming unless you want seedlings everywhere – it self-pollinates and drops hundreds of seeds. Easy from fresh seed, leaf cuttings on wet sphagnum, or root cuttings.
Cape Sundew (Drosera)によくあるトラブルや病気は？
No sticky dew, green stretched leaves from low light or dry air; blackening and decline from tap/hard-water minerals or fertiliser; mould, algae or moss over the media in warm wet tanks; aphids, mealybugs, grey mould.
Cape Sundew (Drosera)のトラブルや枯れへの対処法は？
Only rain, distilled or RO water; keep the medium permanently moist to wet, ideally from a tray below. Grow in peat with sand or perlite, or in sphagnum. NEVER fertilise the soil – it catches its own small insects, fungus gnats included. For mould, add airflow and refresh the surface.
