Are Circular Plant Supports Best?
Thank your for your email.
My advice would be to go for the trumpet supports. I am attaching some photos of this type of support in use in the gardens surrounding the kitchen garden.
We use these circular plant supports to support large peonies which are prone to flopping under the weight of the huge, heavy blooms. We use the largest size available which is 90cm high and has a diameter of 60cm.
It usually a good idea to put the plant support in place early in the season, before the plant has put on growth, however with some careful handling you should be able to place it over your rose bush.
I hope this is helpful. Please let me know if I can be of any further assistance.
