Ok..I understand it will open when it is ready... Mine are still outside... They will come in tomorrow... I wore myself out today getting things inside and into the cool room for winter storage in the snow flurries and colder temperatures... It's 31.6 *F now.... Likely too cold for them.. Will the flowers open when it's too cold for a moth to visit".. I did get two smaller orchid cactuses In...And the 6 ft tall. Dragon fruit plant..and a smaller 3 ft tall one inside.. The 3 epi's fill a 6 ft long planter.. And I have to cut them out in the morning....
Can they take this low freezing temperatures.. Would this bud have ever opened it the temps remained at say40* F.. What's their low limit on surviving
It was just more than I could manage.. Even with some paid help to get it finished before this hit...
