Care Information

  • Your rhododendron should be planted slightly higher than it was in its pot into well-draining soil.
  • Rhododendrons need an acidic soil with a pH of around 5.5 in order to thrive - soils with pH higher than 5.5 should be acidified before planting or you can grow them in a container with ericaceous compost.
