Landscaping Your Yard With PJM Rhododendron

PJM Rhododendron can serve as a spectacular foundation plant, creating an eye-catching display when in bloom.

Its early spring flowers and evergreen nature make it a valuable addition to these settings. It also works well as part of a woodland garden, nestled among trees and other shade-tolerant plants.

Thanks to its manageable size, PJM Rhododendron is also an excellent choice for container gardening. It can add a burst of color to patios, decks, or balconies, especially in spring when it is in full bloom.

Planting Tips

Where to Plant

PJM Rhododendron should be planted in a location with partial to full sun and protection from harsh afternoon rays. It’s ideal for planting under the canopy of tall trees, along the north or east side of buildings, or in sheltered garden spots.


This plant thrives in partial sun, requiring a few hours of sunlight a day. Filtered light or morning sun is preferable to prevent leaf burn from intense afternoon sunlight.


PJM Rhododendron needs well-drained, acidic soil. It's essential to ensure good drainage as the plant is susceptible to root rot in waterlogged conditions.


Space PJM Rhododendrons about 4-6 feet apart. This spacing allows each plant enough room to grow to its full size and encourages better air circulation.

When to Plant

The best time to plant PJM Rhododendron is in the early spring or fall. Cooler temperatures and less intense sun during these times help the plant establish without stress.

How to Plant

Dig a hole twice as wide as the root ball and as deep as its height. Position the plant so the top of the root ball is level with the soil surface. Backfill with soil and water thoroughly.

Plant Care Tips


Water regularly, especially during dry spells, to keep the soil evenly moist. Avoid overwatering, as rhododendrons are prone to root rot.


Fertilize in early spring with a rhododendron-specific fertilizer. Follow the instructions on the label for correct application.


Prune immediately after flowering to maintain shape and promote bushier growth. Remove any dead or diseased branches.

By Season


Spring Care

In spring, mulch and fertilize the plant. This is also the time to prune if necessary, right after the blooms have faded.

Summer Care

Ensure adequate watering during hot summer months. Mulching helps retain moisture and keeps the roots cool.

Fall Care

Prepare the plant for winter by reducing watering. Fall is a good time to add a layer of mulch for winter protection.

Winter Care

PJM Rhododendron requires minimal care in winter. Ensure it is not exposed to harsh winter winds.


How Long Does the PJM Rhododendron Bloom?

The PJM Rhododendron typically blooms for several weeks in early spring, offering a spectacular display of lavender-pink flowers.

Is PJM Rhododendron Deer Resistant?

While no plant is completely deer-proof, PJM Rhododendron is considered to be moderately deer resistant.

Can PJM Rhododendron Grow in Shade?

PJM Rhododendron can tolerate partial shade, but it prefers locations where it can receive some sunlight, especially in the morning. Too much shade can lead to fewer blooms and leggy growth.
