A bamboo core for durability and a coir surface to absorb and retain moisture, grow poles support robust growth of our naturally tree climbing plants. Imitating what would be a tree-trunk in the wild, these coir poles can be used to produce more balanced growth for plants that are veering off to the side and are in need of a central support. Climbing plants will often produce larger foliage when provided with something to climb on. Make sure your grow pole is slightly taller than your plant, so there is room for new growth.
