If you want to garden vertically, one of the simplest and least expensive ways to do it is by using bamboo poles. When I want to add pop to my vertical garden design, I spray paint the bamboo in bright colors.
For a simple bamboo teepee, simply use three (or as many as you want) spray painted bamboo stakes. Stick them as far as they will go into the soil in your container garden. Gather them at the top and use a zip tie to secure your teepee.
Train climbing vines, like morning glories, moon flowers or sweet peas up the bamboo for visual impact.
