Azalea 'Blue Danube' - 8L Pot - Azalea japonica 'Blue Danube'

Azalea 'Blue Danube' is one of our favourite evergreen Azaleas. The intensity of the violet purple colour produced in May is incredible and will brighten up any border.

The flowering goes on well into June and so is worth its space in any bed. As a compact variety it is perfect for use in containers too so you can move it into prime position as it comes into flower.

Blue Danube is a vigorous Azalea and has an upright habit, enjoys dappled shade with afternoon sun and will do well in most soils but prefers slightly acidic, moist ground.

Choose a sheltered site with dappled shade, however, dwarf alpine species will tolerate full sun. Avoid sites exposed to early morning sun in spring, as this may damage frosted flowers.

Ensure the soil conditions are correct. Rhododendrons must have moist but well-drained, acid soil between pH 5.0 and 6.0 that is rich in organic matter.

October or March/April are the best times for planting. Don’t plant deeply, as rhododendrons are surface rooters. Apply a loose 8cm mulch of acidic organic material and water well to finish.

If you have alkaline soil, grow rhododendrons and azaleas as container plants. Use ericaceous loam-based compost and repot every other year into fresh compost in spring.

Caring and Maintenance

To keep your plants performing at their best, in spring, apply slow-release ericaceous fertiliser and renew the acidic mulch and keep well watered.

Rhododendrons don’t require pruning apart from removing dead wood and deadheading if practical. If the plant outgrows its space, cutting back is tolerated best from deciduous azaleas and rough-barked rhododendrons. After cutting back, mulch, feed and keep well watered.
