Rhododendrons are acid-loving plants, meaning they don’t like manure based products due to the high salt content in manure, and require a planting blend with low pH and excellent drainage. Our Rhododendron Mix provides that by blending raw fir bark, 1/4″ minus fir bark, 5/16″ minus lava rock, nitro sawdust, 38-0-0 fertilizer, single super phosphate, dolomite 65, gypsum, and ferrous sulfate. Use as a top dressing for your flowers or blend 50/50 with native soil.
