Rhododendrons & Azaleas FAQs

• What size Rhododendron is right for you?

  The most important question for many gardeners. Dwarf Rhodos and Evergreen Azaleas tend to be slow growing (5-10cm/ year) and reach up to 1m in height, perfect for boarders or as a potted plant. Because of the slow growth rate, it might be a good idea to buy a plant close to the size you want.
  

  Tall hybrid Rhodos and Deciduous Azalea will grow up to 2m, at a rate of up to 50cm a year, but can spread to more than twice that width making them perfect for hedging or screening. Nearly all rhodos respond well to pruning so as long as you are not afraid of a bit of landscaping, you can keep even the large growing varieties at a manageable size.
  

• What is the difference between evergeen and deciduous?

  Evergreens are popular because they offer all year structure but deciduous Rhododendrons offer a fantastic autumn display of fiery colours and grow quicker, to a larger size.

• What are the ideal growing conditions for rhododendrons and azaleas?

  All rhododendrons prefer at least partial shade, either for part of the day or filtered through the branches of a neighbouring tree. This helps ensure the setting of buds and so a good flowering but you can find some sun tolerant varieties.

  The tall hybrid Rhododendrons have the largest flowers and the longest flowering period, sometimes from February through to July. Azaleas have smaller flowers, but the smaller and more intricate petal arrangements create quite the spectacle.

• Do you need to deadhead rhododendrons?

  To keep your flowers healthy and in their best possible condition, you should deadhead your rhododendrons so they don't become an energy drain and affect the growth of other blooms for the following year. This will also tidy them up.

  Prune them when they finish blooming and before new buds develop in late winter when the plant is dormant. Take a look at our garden hand tools and secateurs.

• Where is the best place to plant a rhododendron?

  When choosing a spot for your rhododendron, it should have partial shade with enough sunlight and shade throughout the day. Full shade isn't ideal and could cause your flower to willow – if you plant it without shade, it would need protection from wind. Early morning sun and cold areas of the garden should also be avoided.

  Ensure soil is moist and acidic with good drainage. You can mix in organic matter and compost to the planting hole.

• Are rhododendrons good for bees?

  Planting flowers and plants that are good for bees are not only great for the environment but will help attract these buzzing friends to your garden for a lively garden full of nature and life. Rhododendrons produce a lot of sugar-rich nectar for bees, including honey bees.

• How often should you water rhododendrons?

  These flowers should be watered around twice a week while they are growing. Once the rhododendrons have established, they only need watering when soil is dry – for example, if there have been several weeks without rain.
