Soft rubber caps hold togther the ends of three bamboo canes, creating a natural appearing teepee trellis for your climbing plants. The Cap 'n Grow works best with 4 to 6 foot canes, and particularly well in containers and raised beds. Soft rubber caps hold three bamboo stakes firmly in place to create a natural appearing tipi/trellis for climbing plants like peas, beans, or sweet peas. They can even be used to support vine tomatoes or cucumbers. These handy caps are perfectly suited to half inch bamboo canes. Create uniform growing towers for your pole beans for a very tidy look.
