Rhododendron Mix is a mixture of Mini Mulch Fir Bark, Small Fir Bark, 5/16" Horticulture Lava, and Organic Diestel Compost. Amend your planting hole with equal parts of native soil and Rhododendron Mix. For areas with heavy clay soil plant the Rhododendrons a little higher than the grade. This will provide better drainage and aeration.
We sell the Rhododendron Mix in one cubic foot bag, we supply the bags, you fill them. For larger areas, you will want to purchase the Rhododendron Mix by the cubic yard. We can load your truck or for a fee, have us deliver to your home or job site.
