More about drosera capensis 'red'

Ideal temperature for drosera capensis 'red'

Drosera capensis 'Red' is comfortable in any room a person is comfortable in, roughly 18-30°C; tolerates 5-35°C (65-86°F; tolerates 41-95°F). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.

Cold tolerance & winter care

Drosera capensis 'Red' is frost-tender (USDA 9-11 (tender; grown as a windowsill plant in colder regions), RHS H2). It cannot survive a frost, so in most of the US and UK it lives indoors year-round or summers outside and comes back in well before the first autumn frost — once nights drop toward 10-12°C is the cue, not the first frost warning. Acclimate it over a week when moving between indoors and out so the leaves do not shock.

Humidity for drosera capensis 'red'

Drosera capensis 'Red' sits happiest at around 40-60% relative humidity. Adapts well to average household humidity provided the roots stay wet; no terrarium is needed. Higher humidity boosts dew production but is not essential. The usual low-humidity tell is crisp brown leaf tips and edges while the soil moisture is fine — a sign the air, not the watering, is the problem. If you need to raise it, the reliable methods are grouping plants together, standing the pot on a tray of damp pebbles (the pot above the waterline, never in it), or running a small humidifier in winter when indoor heating dries the air most. Misting is the least effective — it raises humidity for minutes, not hours.

Drosera capensis 'Red' temperature & humidity — frequently asked questions

What temperature is best for drosera capensis 'red'?

Drosera capensis 'Red' grows best between 18-30°C; tolerates 5-35°C (65-86°F; tolerates 41-95°F). Keep it out of cold draughts, off freezing windowsills in winter, and away from the hot dry air directly above radiators — the extremes matter far more than the average room temperature.

How cold can drosera capensis 'red' tolerate?

Drosera capensis 'Red' starts to suffer below roughly 18°C. It is frost-tender and will be damaged or killed by a frost, so bring it indoors once nights fall toward 10-12°C.

What humidity does drosera capensis 'red' need?

Drosera capensis 'Red' prefers about 40-60% relative humidity. Adapts well to average household humidity provided the roots stay wet; no terrarium is needed. Higher humidity boosts dew production but is not essential.

How do I raise humidity for drosera capensis 'red'?

Group it with other plants, stand the pot on a tray of damp pebbles (kept above the waterline), or run a small humidifier in winter. Misting only helps for a few minutes, so it is the weakest option for a plant that genuinely needs more humidity.

Can drosera capensis 'red' live outside?

Drosera capensis 'Red' is rated for USDA zone 9-11 (tender; grown as a windowsill plant in colder regions) and RHS hardiness H2. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
