Such as Roses, Forsythia, Honeysuckle, Boxwood, Wax myrtle, Rhododendron, Camellia, Azalea, Holly, Magnolia, etc. NO DAMAGE - Provides no damage to the parent plant at all as it only uses a small branch on the plant you wish to clone, thus creates little to no disturbance and doesn't disturb the plant's natural growth. STRONG & FAST RESULTS - This is especially created with a cutting globe design which helps your cuttings achieve stronger roots to reproduce a more mature plant faster than normal propagation methods. It allows you to see propagation results within 6-8 weeks after installation. SECURE LOCK - Designed with stoppers and corner locks which interlock with each other and secure on the branch to hold the propagator in place even without a stem underneath. However, you can use plastic ties to hold the shells securely.
