Vermiculite is a neutral mineral, not alkaline. Cultivated azaleas are not suitable for vermiculite. In plant cultivation, vermiculite can be used as soil conditioner, vermiculite has the characteristics of loose soil, good permeability, strong water absorption and little temperature change. The Rhododendron culture soil requires good aeration and humus rich acid soil. The value of pH is 5.5 to 6.5.
