Expert Advice on How to Grow Azaleas

Published May 11th, 2022 by J. Berry Nursery

Are you a gardener looking for ways to make your azaleas stand out? These flowers come in a variety of colors and make a beautiful addition to any garden.

Before you and your guests enjoy vibrant colors like red, yellow, pink, and orange, you must give your azaleas the chance to flourish!

As part of the Rhododendron family of plants, your azaleas are perfect for temperate climates with damp conditions. Read on to learn how to grow azaleas the best way!

The Importance of Soil and Mulch

One of the tips for growing azaleas is not to overlook the importance of the soil and mulch you use. The soil where you plant an azalea should be acidic. This means that the soil should have a pH range between 5.0 to 5.5. If your soil leans towards neutral or alkaline pH, no worries: amend your soil with aluminum sulfate (found at garden centers) to reduce the pH and help your plant thrive.

The soil should also be full of humus. What is humus and why is it important?

Think of humus as the nutrients found in varying amounts within the soil. Humus exists as a result of the decomposition of matter. It's the dark, organic matter that forms when plant and animal matter decay, breaking down into chemicals that are important nutrients for plants' survival. Humus includes nutrients like nitrogen, but also makes soil more aerable, letting water drain easily and ensuring oxygen reaches plants' roots.

Your mulch should be spread evenly along the surface of the soil. This helps to ensure the azaleas stay moist even in dryer times of the year. Some of the best mulch to use is an oak leaf or pine.

Watering Your Flowers

As part of the Rhododendron genus of flowers, growing azaleas means you need lots of water during dry seasons. This is because they thrive in moist but well-drained conditions.

If you live in a dry climate or go through drought-like conditions during certain times of the year, monitor azaleas closely. If you are in a moderate climate and have mulched your azaleas well, they can thrive with little daily care once established.

Give Them Some Space

Azaleas look the best when they are planted in groups and not just singularly! Like most plants though, azaleas need some space because they will grow over time.

It's best to give your plants at least two to six feet of space between each other, depending on the variety. Besides the space between shrubs, you should also be mindful of how deep you put them in the ground.

Be sure to dig your hole as deep as the root ball of your new azalea. To give your flower space to breathe and grow, make sure that the hole is two times as wide as that root ball before you plant it. Add compost to amend heavy clay soil and improve drainage.

Some azaleas bloom beautifully in the Spring, then add a nice backdrop of foliage for the rest of the season. Others repeat bloom, giving you a long season of beautiful blooms. Make sure you know which type you plant, especially when pruning.
