Montana growth habit
I hope this hasn't been answered before. I tried search but could only really find information on the height of these plants. I'm curious about the size of montana after a few years. I've read about the height but have had trouble finding information about its spread. How rapidly does it grow? When using a wire trellis does one wire usually accept on vine?
I have some thick clay that I'd like to put raised beds over (~20"). Will this be enough room for the roots to thrive? Thanks for everyone's help.
