When and how to water it

The right fertilizer

During spring and summer, it is important to feed your Azalea with a fertilizer specifically for acid-loving plants every 30 days. This will help the plant maintain healthy green foliage and produce abundant flowers.

The pot and soil

For its growing medium, the Japanese Azalea prefers acidic, well-drained soil. A mixture of peat, sand, and perlite is ideal for ensuring the right balance of drainage and water retention. Remember to repot the plant when necessary, choosing a pot that allows the roots to spread comfortably.

How to propagate it

The Japanese Azalea can be propagated through cuttings or layering. Semi-hardwood cuttings are preferable in summer, when weather conditions favor rooting.

Our final advice

The Japanese Azalea is a plant that, with the right care, will reward you with spectacular blooms. Don't forget to check the soil regularly and adapt its care to the seasons to keep it healthy year-round.
