I love Azalea flowers because they have a lot of color and smell wonderful. But the best thing about them is that they will make any garden look beautiful.
In many parts of the world, including the United States, it is never springtime if the Azalea Shrubs have not flowered. They make spring more colorful, especially from late March to early April. There are over 10000 species of Azalea, and all of them are very beautiful and burst with color. Azaleas have been bred for centuries as there are thousands of cultivars.
All the species have been derived from different species in the Northern Hemisphere. Most of the species are natively from the western part of China. This species has been hybridized a lot, which means there is always a new variety coming up. Azaleas can now survive in Northern climates, below the 23 most common types of Azalea varieties.

Azalea Varieties Care Tips
If you plan to plant the Azalea flower, you should know how to care for them. The first thing to learn is how to water them. They need consistent watering, like one inch of water per week. Ensure that you check the soil around the plant regularly, and if the soil feels dry, you should water it. In the late spring, you have to fertilize it because it is an acid-loving plant.
However, you have to make sure that you don’t over-fertilize because the roots are sensitive. If you apply too many nutrients, it will burn easily. If you want new growth, then you should use new cuttings with the top cluster alone. Pruning should be done after it has finished blooming, which is at the start of summer.
Prune lightly to get rid of broken branches, diseases and not look like a bush. If you notice it has some form of disease, especially curling of leaves, get rid of the affected leaves. Or mildew, use a fungicide and destroy and prune all the parts that have been affected.
