Everything You Need to Know About Azaleas for Your Flower Garden
If you live in the United States, particularly in the Southeast, chances are you’ve marveled at the beauty of azalea shrubs in full bloom during the spring. These vibrant flowers, part of the Rhododendron species, add a burst of color to woodland gardens from late March to early April. With centuries of selective breeding and thousands of cultivars derived from hundreds of species, azaleas have become a staple in gardens across the country.
The Difference Between Azaleas and Rhododendrons
Before we dive into the different types of azaleas you can add to your garden, let’s briefly understand the distinction between azaleas and rhododendrons. While both belong to the Rhododendron genus, azaleas have 5 stamens in their flowers, while rhododendrons have 10. Azaleas also tend to have smaller leaves and branches, are often deciduous, and bloom earlier than rhododendrons.
Tips for Growing Azaleas
Like their rhododendron relatives, azaleas thrive in rich, acidic soil with a pH of 4.5 to 6.0. To ensure your azaleas flourish, consider mulching regularly with pine needles or other acid-rich organic materials. Additionally, feeding them with an acidifying fertilizer can help maintain optimal soil conditions for growth.
