The Basics
Ideal soil
Acidic soil, good organic content, pH 4.5-6.0. Inkarho range of rhododendrons will tolerate soils up to pH7.5
Sun or Shade
Light dappled shade is best for most varieties.
Shelter
Refer to hardiness rating. Give young plants protection.
Avoid close to trees, roots, invasive weeds, walls, hot patios, dry banks and waterlogged soils. Do not use weed matting or stone mulch
Plant spacing
Use the height shown in 10 years as a guide to the distance between each plant. Allow room for plant to fill out. If planting closer for instant impact, be prepared to move plants after a few years.
Compost
- 3 litre pot, dig in 10-20 litres of ericaceous compost.
- 7.5 litre pot, dig in 20-30 litres of ericaceous compost.
- 70-80cm specimen, dig in 60 litres of ericaceous compost.
- 100-120cm specimen, dig in 120 litres of ericaceous compost.
Planting depth
Plant high in the ground, with the top of the rootball visible.
Feeding
Slow-release ericaceous feed recommended in March and straight after flowering.
Mulch
Recommended every few years.
Water
The key ingredient! Keep moist all season, especially the critical time at end of June for flower bud initiation. Tap water is better than no water. Heavy dose at least once per week in dry weather.
Drainage
Ensure good drainage in winter, especially with yellow varieties. Avoid waterlogged sites.
Pruning
Not normally required. Tidy wayward shoots after flowering. Evergreen azaleas and Bloombux can be clipped into a low hedge.
Deadheading
Remove old flower-heads, particularly on young or weak plants.
