- Place the azalea in the center of the larger pot.
- Fill up the planter.
- Water with lime-free water.
In which substrate is an azalea repotted?
Azaleas in the pot prefer one acidic substrate. The pH should be between 4 and 4.4. Therefore, the easiest way is to repot your azalea in rhododendron soil.
An alternative is conventional potting soilthat you mix with sand. However, you should pay attention to the pH value. If this is too high, the plants cannot absorb any nutrients.
Tip
Repotting and fertilizing often do not get along
Although azaleas in pots prefer a humus-rich substrate, you should not over-fertilize the indoor plants. If you use special soil from specialist shops, you should check how long your room azalea can survive without additional fertilizer. You can find the information on this on the packaging.
