Adding a patio trellis to any planted area enhances the beauty of the natural landscape. A patio trellis is a support that climbing flowers and vines can use to grow vertically. Trellises can be employed to great effect in your gardening by adding vertical interest in flowerbeds. There are several ideas of patio trellis. For instance, if your patio is just a wide open space, dot your patio space with planters with trellises. You can purchase large pots and place small trellises inside, or if you’re handy, you can build your own planters with trellises attached to the back. Put four planters in a square back to back to create a post-like effect, or use a number of planters with trellises as a patio divider.
