If you want to encourage more buds to bloom this spring, you need to redirect your climbing roses to grow outwards rather than up. "By training the stem horizontally, you encourage multiple flowering shoots instead of a single tall one," Orpheus tells us. Why training climbing roses horizontally encourages better blooms...Training a climbing rose to grow sideways will reward you with more flowers all along the stem. And fear not, because now is the best time to redirect your climbing plant, aligned with the best time to prune roses . Do this for all of your climbing roses; they want to be horizontal, not vertical."
