Besides, they cause no damage during propagation, which are sturdy and durable enough to be used again and again. [Unique Design] They are designed with an automatic buckle that locks and attaches to the branch to hold the greenhouse without a stem underneath. You can also use plastic ties to secure the root box. [No Harm]: They do no harm to the mother plant as it only uses a small branch on the plant that you are trying to clone. As a result, the natural growth of the plant is not disturbed. [Easy to use] The rooting propagation ball can allow the roots to grow directly on the branches, the design with balls pruning can allow plants to reproduce more quickly. You can check rooting results within 6-8 weeks of installation. [Wide Range of Applications] Plant Rooting Ball works for both indoor and outdoor plants or for plants with heavy roots, e.g. roses, vines, trees, fruit trees, magnolias and camellias.
