Winter Rose Propagation
I live in Colorado where dry air and irregular weather makes propagating roses from cutting extremely difficult. Under glass they keep drying out, rotting, drying out, rotting... I've gotten larger chunks of stem to successfully root but then they died.
It's also difficult that I live in a city apartment with little room for plants, but do my "experiments" at my parents' house where I grew up and can only check projects about once a week.
I think I tend to give cuttings "too much love" and have often found that I have the best luck with plants while breaking all advice and worse luck when I pamper them.
I'm wondering if anyone's ever had luck with "grandma's method" of sticking rose stems (perhaps ranging up to large branches) in the ground with a mason jar greenhouse in late fall or even winter. It never gets cold enough here for the ground to freeze consistently; it freezes and thaws numerous times. Also roses here are occasionally green into January by a South-facing brick wall and the warmth of the mason jar may make them evergreen. Intuitively, it seems that the cold might force partial dormancy which would keep the cuttings from drying as they slowly root, the cold suppresses fungus and insects, and the slower pace of winter gets more mileage with only weekly visits. Does anyone think this is possible or have thoughts that would help?
Beyond that, I have finally given in and set up a more controlled nursery with an artificial light that is soft but can be run for 16-20hrs a day, rather than trying to strike cuttings in a window in various types of homemade greenhouses. Will that be successful in winter?
My goal is to have roses that will be ready to begin growing in the ground this spring.
