Azalea japonica Johanna - Plant in a 9cm Pot
The Rhododendrons, of which Azaleas are one, are perhaps the most important and diverse group of plants in the world with over 1000 different species. Native to many locations, mainly in the northern hemisphere, they are at their most prolific in the vast mountain ranges and gorges bordering China, Tibet and Upper Myanmar. They contain some of the most noble and stunning of all plants and when planted in well designed landscapes are almost unrivalled in their impact in spring. Today they have a dominant position in many of our parks and gardens, large and small. Johanna in addition to stunning garden performance will make a good Bonsai subject. It was derived from a cross between Azalea japonica Florida and an unknown seedling around 1966. A very popular variety it produces large carmine red flowers in May. In addition to the flowers the foliage is one of the best for reddish autumn winter colour. An attractive and traditional colouring with an upright habit and reliable performance. One important fact to note with virtually all Azaleas and Rhododendrons is the fact they are very intolerant of chalk/lime. Even small amounts will turn them chlorotic and unhealthy. Regular use of a suitable tonic (sequestered iron) will combat the effects of low levels of lime but it is far better to plant in lime free acid soils. Azaleas and Rhododendrons have shallow fibrous roots so an annual mulching with organic matter is very beneficial, best applied in autumn. This plant can be used in a mixed planting or as a stand alone specimen in the garden or a container. If planting in a pot or other container use a good quality ericaceous John Innes compost as this plant will be there a long time and peaty types of compost eventually degrade and become too packed and choke the roots. Ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmocote pro 12-14 month applied in the early spring.
