Azaleas and rhododendrons have long been favorites for their large, vibrant blooms that bring color and impact to the spring landscape. With the right care and placement, these plants can become a standout feature in your yard year after year.

At Suburban Lawn & Garden, we carry both tried-and-true varieties and newer selections well suited to our area. With a few key steps, you can enjoy healthy plants and beautiful blooms that return each season.

For the best results, plant azaleas and rhododendrons in an area that receives morning sun with protection from the afternoon heat.

An eastern exposure is ideal, providing direct or dappled sunlight through late morning or early afternoon. While these plants may survive in areas with filtered afternoon sun, they will truly thrive when protected from intense afternoon exposure.

Azaleas and rhododendrons prefer well-drained, organically rich soil that retains moisture without becoming waterlogged.

A reliable planting mix includes:

• 1/3 native soil
• 1/3 organic soil conditioner
• 1/3 peat moss

Blend thoroughly to create a light, well-balanced backfill that supports healthy root growth.

• Dig a hole 1½ to 2 times wider than the root ball
• Keep the depth equal to the root ball height
• Place the plant so the top of the root ball sits at or slightly above ground level
• Backfill with your prepared soil mix, gently firming as you go

Apply 2–3 inches of mulch, keeping it a few inches away from the base of the plant

After planting, give your plant a strong start with a root stimulator solution.

Mix 5 gallons of water with 1 cup of root stimulator, then slowly water the soil around the root ball. Focus on saturating the soil rather than the foliage.

Continue checking moisture levels regularly, especially during the first growing season. Depending on rainfall and temperature, watering at least twice a week is a good starting point.

The best time to prune azaleas and rhododendrons is immediately after they finish blooming in spring.

Pruning too late in the season can remove next year’s flower buds, reducing future blooms.

Fertilizing helps support strong growth and consistent flowering.

We recommend using products designed specifically for acid-loving plants like Espoma Azalea Tone and Holly Tone.

Apply according to label directions for best results.

With proper placement, soil preparation, and care, azaleas and rhododendrons will reward you with stunning blooms each spring. These plants are a long-term investment in your landscape, offering beauty and structure for years to come.
