The Japanese azalea is closely related to the rhododendron - in fact, it is actually a hybrid that arose from different rhododendron species a few hundred years ago. In fact, both plant species are very similar in terms of their requirements and needs.
The Japanese azalea feels most comfortable in partial shade
Do not plant azaleas in full sun
Like rhododendrons, the Japanese azalea does not belong in full sun. Instead, place the flowering shrub in the light semi-shade. The plant feels most comfortable in the protection of tall trees, although these must not compete for nutrients and water.
Bog plants need acidic soil
Azaleas also prefer to grow in swampy landscapes, which is why they naturally prefer acidic and nutrient-rich soil. Ideally, the pH is between 4 and 5.5, with the soil being permeable and rich in humus.
tips
If your garden soil does not meet these requirements, you can easily upgrade the planting site with rhododendron soil or another peat mixture. However, do not use pure peat, as this is too acidic even for azaleas.
