My Louise Odier Rose Bush (David Austen Roses) is now into it’s second year. I planted it Bare Root, and now it is getting along well. It is not as fragrant as I would have expected from the descriptions. But it may be due to it’s age / soil / health.
Hardiness: We’ve had -20C (-20F) weather the past 2 years, here in Toronto (Zone 5), and the Rose Bush has survived without any issue. There is very minimal dieback each spring. This year, we had a crazy winter, where we hit 25C (80+F) in Feb/March. The Bush start budding and grew branches before we went back down to 0C weather. I thought my Louise Odier Bush was dead for sure. And we definitely had branch dieback, but overall, it did fine.
Editor: Come May, the bush is entering bloom time. It did fine!
Disease: I dont have much disease issues with this plant. It’s in full Sun, but gets several hours of Shade after 6pm daily. It attracts aphids, but nothing out of control. It does pick up fungus, but ussually late in the season, and it’s reasonable. It does not take over the bush. Overall, I’m very happy with my Louie. My only complaint is that it is not as fragrant as advertised. Regardless,incredibly beautiful.
