Plant Information

Top Tips

  • Mulch plants and water deeply and regularly during dryer periods from July onwards.

Care Guide

  • Rhododendrons with tolerate a more open site as long as they are sheltered from cold, drying winds and early morning sunlight.
  • 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.
