Ideal temperature for fig 'black mission'
Temperature kills fewer fig 'black mission' plants than you'd think. What kills them is the micro-climate within a normal-temperature room — a leaf pressed against single-glazed winter glass, the hot dry updraft directly above a radiator, the cold blast from an AC vent. The thermostat reading at 18-32C (growing); hardy to about -9C dormant (64-90F (growing); hardy to about 16F dormant) is fine; the spot you put the plant in matters more. Below roughly 18°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Fig 'Black Mission' is comparatively hardy (USDA 7-10 (best in 8-10); container in colder zones, RHS H4). Within that range it tolerates a cold dormant spell outdoors; outside it, grow it in a container you can move under cover or overwinter in a cool but frost-free spot. Hardiness assumes an established plant in well-drained soil — a wet, cold root zone kills far more plants than cold air alone.
Humidity for fig 'black mission'
Fig 'Black Mission' sits happiest at around Ambient outdoor relative humidity. A Mediterranean-climate fig that prefers warm, fairly dry air. Damp, humid conditions raise the risk of fruit souring and fungal leaf spot. 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.
Fig 'Black Mission' temperature & humidity — frequently asked questions
What temperature is best for fig 'black mission'?
Fig 'Black Mission' grows best between 18-32C (growing); hardy to about -9C dormant (64-90F (growing); hardy to about 16F dormant). 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 fig 'black mission' tolerate?
Fig 'Black Mission' starts to suffer below roughly 18°C. It tolerates a cold dormant period within USDA 7-10 (best in 8-10); container in colder zones, but a wet cold root zone is more dangerous than cold air.
What humidity does fig 'black mission' need?
Fig 'Black Mission' prefers about Ambient outdoor relative humidity. A Mediterranean-climate fig that prefers warm, fairly dry air. Damp, humid conditions raise the risk of fruit souring and fungal leaf spot.
How do I raise humidity for fig 'black mission'?
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 fig 'black mission' live outside?
Fig 'Black Mission' is rated for USDA zone 7-10 (best in 8-10); container in colder zones and RHS hardiness H4. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
