Rhododendrons prefer acidic soil and sheltered conditions, and they grow best in areas with high rainfall. Also, they will happily grow in raised beds. However, it’s important not to plant them too deep – the top of the root ball should be level with the ground’s surface, or even an inch or two above it.
Compact hybrid varieties can also be planted in containers, whilst dwarf alpines are suitable for rock gardens.
Other species include azaleas, which are often used as hedges or around foundations. Also, many larger-leafed rhododendrons lend themselves well to informal planting and woodland gardens.
