We've spent the last 3 years working on growing our rose bushes tall, but this year very few exsisting canes are turning green and sprouting leaves. it seems like there is only new growth canes at bottom. We did have a late snow in April, is it possible all the canes are dead?
Up until now the entire bushes have always filled out each spring with no problem .
Or is there a way to prune to encourage leaves in the exhausting canes?
Or maybe I just need patience?
