is it safe to let it stay out in the cold after it rooted?

winnie13(ma)August 16, 2007

i just start rooting some rose stem outside, and some are already rooted, my question is what happens if i just let them stay outside over the winter... i don't want to carry them inside, is it safe for them to be staying outside over the winter since they are newly rooted roses?

they are in a pot, if i put lots of mulch over them would that help protect them?

Did you root them in the ground or in pots? If they are in the ground, it will be okay to let them winter over.

If the pot is above ground, it will freeze and the roots will freeze and the plant will die. If you have an unheated basement, you could keep them there. Otherwise you may need to bury the pot in the ground. From all I have read MA weather is rough on roses.

I have successfully rooted just one rose this summer, Polarstern, a HT. Its parent generally does not need winter cover here in Iowa to overwinter.

It is about 4 inches tall w/ lots of new leaves and a couple tiny branches sprouting. I have had it in full sun now for about three days w/ no ill effects. It is in a 4" pot.

Can I plant this in the ground and mulch well, and will it make it through winter? Should I plant it now, or wait until we get a freeze.

If I left it in an unheated dark shed instead, how would that work? I am guessing I'd need to water all the time and put the plastic liter pop bottle over it, but w/ roots above ground that would seem a harsh environment? Thoughts please!

If it were mine, Mark, I would repot it into a one or two gallon pot and plant it pot and all till next spring. Then, I would probably let it really develop a strong root system in the pot before planting it sans pot for good. I might even use a bottle again over winter to protect the wee darling from critters, taking the cap off in spring so that there is not too much moisture inside to cause mildew or rot.

Steve,

Thank you. I will give your procedure a go. I do have an area that is better protected from wind over winter than the ultimate destination I have in mind for this new rose. I think this sounds like a good way to go, and will keep its roots together for later transplant.
