I am facing a problem I have 2 auto's facing some overnight lows that will be around 40F/4C average 50's till Nov. daytime temps range 65-75f/18-24C they in flower about 6weeks old. Always full sun. These overnights will be temporary, nothing for 15 days after. Will they be ok?
Most canna will be fine with night time 40s. Below 40 gets risky. Ruderalis/auto genetics should be more resilient in cold temps, I wouldn’t worry personally.
They appear to be in pots. Pull em inside on the super cold nights if you’re really concerned.
I’ve had 6 plants outdoor this season and I’ve had 37-38 lows a few nights already and they’re totally fine
