Water
Proper watering is crucial for the health and vitality of evergreen azaleas. These plants prefer consistently moist but well-drained soil, especially during the growing season. However, it’s important to avoid overwatering, as waterlogged soil can lead to root rot and other detrimental conditions. During periods of drought or dry weather, it’s essential to provide supplemental watering to maintain adequate soil moisture.
Watering Tips:

Sunlight
The evergreen azalea thrives in partial shade to full sun, depending on the particular variety and local climatic conditions. While these plants appreciate filtered sunlight to protect them from intense heat and direct sunlight, they also benefit from receiving ample light to support healthy growth and prolific flowering.
Sunlight Requirements:
– Partial Shade to Full Sun: Provide a balance of sunlight, ensuring protection from intense heat.
