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.
