Sorry I do not have a picture because the rose is just a few bare canes right now. I bought this rose from Walmart 3 years ago. Now it has 4-6 tall canes (2-3 meters). It has big thorns. Judging from the height of the canes, do you think this is a climbing rose? If yes, how can I multiple it? by cutting small branch and plant it? When I can do that? Thank you very much.
Thank you for contacting the Toronto Master Gardeners concerning rose propagation.
Without a photo it is difficult to know if you have a climbing rose or a shrub rose. There are many type of roses which can grow 4-6′ tall, the tallest being Grandiflora roses. This article on 28 different varieties of climbing roses could help you narrow down your type of rose.
Please see this article How to Grow Roses from The Royal Horticultural Society that speaks about different propagation methods for different roses and time of year to best begin your cuttings.
Lastly, there are a number of You Tube videos available online on how to propagate roses once you have narrowed down your rose type. Simply goggle “Rose Propagation” in your browser.
Good luck with your rose.
