Ideal temperature for thai silk mix california poppy
Temperature kills fewer thai silk mix california poppy 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 5-25°C (40-77°F) is fine; the spot you put the plant in matters more. Below roughly 5°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Thai Silk Mix California Poppy is comparatively hardy (USDA Annual in zones 3-8; self-sowing perennial in zones 8-10, 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 thai silk mix california poppy
Thai Silk Mix California Poppy sits happiest at around 30-55% relative humidity. Native to dry, Mediterranean-climate California; prefers low to moderate humidity. High humidity combined with wet soil greatly increases susceptibility to fungal crown and root rots. Excellent air circulation is beneficial. 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.
