Most of my success has been over the winter.and the best year has been THIS winter.I stuck a few in ground in beds where wanted them& 3 have made it.I have about 5 cuttings that have made it back by scrap pile that sat in a hanging basket...cause simply the soil wasn't being used at time(morning glory finished) my long wild pink once blooming
rose....I stuck a few canes under the soil and have dug up the starter plants.MIL's is planted& SIL may have killed hers as it hung on my fence for 2 days and then she left it in her truck (she's asked me if it will live....she has it in water.its leaves have dried) Try 1 year old wood.it will take at LEAST 8 weeks.I think if your weather is still cool and your
roses are still dormant....it might work. I didn't use rooting hormone this year. I rooted my red
rose for my sister& step dad about 6 years ago.His has not bloomed but I hear its in shade.Sis's is doing great.she said in its 3rd year it took off& tripled in size.
My luck may be due to my humidity year round.I ignored them completly too.
