1. The rooting propagator ball uses the old air stratification method to try to root directly on the branches to replicate existing plants and produce new plants. 2. Reusable: The air spreader shell is sturdy and durable and can be reused repeatedly, so you can clone more plants according to your preferences. 3. Safe plant: It will not cause any harm to the mother plant at all, because it only uses a small branch on the plant you want to clone, so there is almost no discomfort and will not interfere with the natural growth of the plant. 4. Strong and fast results: This is specially made with a cut spherical design, which can help your cuttings get stronger roots and reproduce more mature plants faster than normal propagation methods. 5. Wide application: suitable for indoor and outdoor plants, such as roses, climbing plants, trees, fruit shrubs, fruit trees, and hard-rooted plants such as magnolia and camellia.
