Q.propagating cuttings to winter over
I have a sm. 6×8 unheated greenhouse. Is there still enough time to take cuttings on my houseplants and establish roots before I have to bring them in for the winter? The plants in question are:
spider plant
string of beads
strawberry begonia
rhipsalis
streptocarpella
Thank you for any help or info.

All of the plants mentioned will not survive in below freezing temperatures.
You can certainly take cuttings from all of the plants, but you will need to do the propagating indoors in a warm location.
