These bamboo stakes work as plant stakes and markers. They are great as supports for your potted plants. At 8-10mm in diameter, they are thick enough for most gardening tasks. If you have to stake something heavy, just double them up and they will do the job for you. Use them to build a trellis or a tripod for your most demanding jobs. They are perfect for staking tomatoes, cucumbers, peppers, beans, and peas.
