I have four climbing hydrangea that are about one year old. They are planted by my four arbor posts and are healthy and growing. I want them to grow up the posts and cover the top of the arbor. They are not wrapping around the post, what is the best way to achieve this? Will it hurt them to tie them to the posts? Thank you.
The vines will need some help to attach to the posts. You can purchase plant twist ties that will work to help hold the vines to the post.
You can also wrap the posts with hardware cloth; the vines can easily attach to the surfaces of this metal fencing.
