Plant of the Month: Azaleas and Rhododendrons

Azaleas and Rhododendrons are the jewels of the late spring garden. Rhododendrons and evergreen azaleas provide interest all year round, while deciduous azaleas produce excellent autumn leaf colours. There are literally thousands of species and varieties and a huge range of flower colours. Their exquisite blooms bring notes of exotic colour to pots and containers, beds and borders and lightly shaded areas under trees.  Some are compact enough for the smallest gardens, others require the space of a woodland where they can reach massive proportions.

Planting

Planting time: October – March/April 📆

Location: Full sun/Partial shade 🏡

Flowering Time: April – July 🌸

Rhododendrons and Azaleas prefer well drained and light/acidic soil. Before planting, dig-in plenty of neutral or acidic organic matter (composted tree bark, leafmould, decomposing pine or spruce needles), and mix in well with the soil. Do not plant too deeply; all rhododendrons are surface-rooting and the roots should be just covered. Apply at least an 8cm (3 inch) mulch of chipped conifer bark or another acidic material. The mulch should be well-aerated, not firmed down.

Complete Guide: How to Plant Buddleia

Looking for advice on how to plant Buddleia this spring? Through this informative guide, we will share all our best knowledge and tips on the planting, arrangement and aftercare for your Buddleia shrubs. When it is covered in butterflies, no other garden plant brings so much pleasure on a summer’s day!

Buddleia, also known as Butterfly Bush, is one of Britain’s most popular summer flowering shrubs. Buddleia comes from Asia and there are more than 100 species that have spread from northern India, China and South Africa to Central and South America, largely after being introduced by the great plant hunters around the beginning of the 20th century.

Planting

Buddleia are superb additions to the garden for attracting wildlife with butterflies and bees being big fans of this shrub. Known for their burst of colour and their distinct tubular fragrant flowers, this vigorous, deciduous shrub is the perfect choice for summer blooms. Here are our guides to planting out in the garden and in containers for easy planting this spring.

In the Garden

Great for long-term borders/rockeries. They perform best when planted in full sun (or at least in partial shade) and in fertile, well-drained soil. Dependent on the variety, plant around 5 to 10 feet apart for a gorgeous display. Plant Buddleia in Spring or in Autumn before the first frosts and water thoroughly after planting.

Buddleia Mixed (Hardy)

Tips

  • When planting, loosen the soil and mix in compost and dig a hole twice the diameter of the plant container.
  • They will not perform well if grown in soil that tends to retain a lot of water in the winter.
  • Do not plant under trees.

In Containers

Use a pot deep enough to contain the roots and heavy enough to weigh the plant down. Make sure the pot has a good amount of drainage holes to allow the roots to breathe. Place the pot in full sunlight and water regularly. Cut the plant back around 10-12 inches in late winter or early spring.

Our Tips

  • Whisky Barrels make great planters
  • Avoid garden soil which becomes heavy/compact in containers.
  • Dwarf varieties like our Minature Collection are the best choice for pots and containers.

Video Tutorial

In this gardening tutorial, our resident gardening expert Jeff demonstrates how to plant Buddleia (Butterfly Bush) for summer flowering and shares his tips and tricks for getting the best results out of these beautiful shrubs.

Aftercare

  • When in bloom, you can snip their stems for honey scented cut flower bouquets.
  • Buddleia can be pruned hard after flowering, and you should cut shoots back to strong buds/younger growth.
  • We recommend reducing plants by half in Autumn when they are grown in windy positions.
  • Removing the dead blooms and watering the plants in very dry conditions will bring butterflies flocking to your Buddleia plants.
  • You can take softwood cutting in late spring just as the stems begin to harden up a little.
