Living Earth makes a selection of special soil mixes. Our Rose Soil Mix comes in bulk or bags as does Azalea Soil. Both these soil blends are meant as top-shelf soil amendments. Roses like a heavy, yet well-drained mix with plenty of organic content. Azaleas want a slightly acid mix suitable for their fine root systems. In Dallas / Fort Worth Living Earth blends Sphagnum Peat into Azalea Soil. In Houston, Pine Bark is added to both Rose Soil Mix and Azalea Soil.
