How to Use Boursault Rhododendron in the Landscape

With their irresistible spring blooms, Boursault is a superstar accent border shrub. Draw the eye along your partially shaded garden path with a long, winding row of them.

Mix in with other Rhododendron varieties that bloom a bit earlier to extend your glorious season of bloom. Try the early blooming PJM series as a counterpoint to kick the season off. They also partner beautifully with Azaleas, as well.

Boursault is a great selection to use in foundation plantings, but give it enough room to make a statement. Try it at the corner of your house and allow them to fill in to their full height and width to amaze your neighborhood.

People will slow down in their car to get a good look. Get the most from your space by adding a flagstone patio nearby, complete with comfy seating.

Use behind your patio to give you a welcome private retreat. You can even create a special Garden Room using a series of these as "living walls" to surround all sides of your space.

You'll have to count the hummingbirds that visit your shrubs! With their preferred funnel-shaped blooms, Boursault should be a staple in bird and butterfly friendly gardens.

Plant multiple shrubs to fill a wide, open area with their spreading habit. Massed plantings grow into an incredible feature! Use a zigzagging planting pattern spaced 4 feet apart for faster results. Measure from the center of one to the center of the next.

#ProPlantTips for Care

Plant in a spot where they will receive morning sun and part shade in the afternoon. Acidic soils with a low pH between 4.5 to 6 and a high concentration of organic materials are best. Rhododendrons also require very well-drained soil.

If you have clay soils or poor drainage, consider creating a raised bed with a heaped mound of native soil from another part of your yard.

You can incorporate several handfuls of compost, and acidic soil conditioner, but try not to overdo it. The root system should spread wide and grow down into your unamended native soil, after all.

Use Nature Hills Root Booster when planting to support the root system as it grows and for the life of the plant. Follow directions on the package.

Top dress your plant with a light layer of acidic pine park during the growing season. This will work naturally to improve the quality of your soil over time.

Please don't disturb the shallow root system. Keep the area underneath free of weeds for best results.

Apply a regular application of water to keep them evenly moist. With proper care, Boursault is actually a very low maintenance variety.

With its attractive green foliage all year, and showy lavender blooms, you can rest assured that Boursault is an outstanding choice for your landscape. Order yours today!
