My epiphyllum cacti, despite being abused quite horribly over the winter - I have just now watered them for the second time since November - are about to flower. Some of them, anyway. As in, they will flower this week. Since no one but me is interested in spending any time in my crowded greenhouse, only I will see them. This makes me want to move them outside. But I believe that they are supposed to stay indoors until night time temperatures hit 10C and they are predicted to be only 2C or 3C this week - although it will be at least 2C warmer in my yard. Does anyone know if they would be OK if moved outside now despite the low temperatures?
