Just like my bush seedlings, I like to give my pole/vining seedlings some support. The main pole plants that I have growing on my cattle fencing trellis are peas, beans, tomatoes and winter squash.
My top two supports for pole seedlings and plants are: 1) I use 3 kabob sticks around the seedling to protect them from garden wildlife and high winds and to help the seedlings grow towards the trellis. 2) Also, I use gardeners ribbon to help the tendrils grab on to the trellis.
