How to Plant a Mountain Laurel Tree

Mountain laurel (Kalmia latifolia) is a beautiful evergreen shrub that produces clusters of lovely pink or white flowers in late spring to early summer. It is native to the eastern United States and can grow up to 15 feet tall. Here are the steps to successfully plant a mountain laurel tree:

Step 1: Choose the Right Location

Mountain laurel prefers a sunny to partially shaded location with well-drained soil. It can grow in a variety of soil types, including loam, sand, or clay, but it does best in acidic soil with a pH of 4.5 to 6.0. Avoid planting in areas with stagnant water, as this can lead to root rot.

Step 2: Prepare the Soil

If the soil in the chosen location is lacking in nutrients or has a pH that is too high, you may need to amend it. To lower the pH, add elemental sulfur. To improve the soil quality, mix in compost or a slow-release fertilizer. Dig a hole that is twice as wide and just as deep as the root ball of the plant. Loosen the soil at the bottom of the hole to allow for good root growth.

Step 3: Planting the Tree

Remove the plant from its container and gently loosen any tangled roots. Place the plant in the hole, making sure the top of the root ball is level with the soil surface. Backfill the hole with the soil you dug out, and gently firm the soil around the plant with your hands. Water the plant thoroughly to help settle the soil and remove any air pockets.

Step 4: Mulch and Water

Add a layer of organic mulch, such as bark or wood chips, around the base of the plant. This will help retain moisture, suppress weeds, and regulate soil temperature. Keep the mulch at least 2 inches away from the stem of the plant to prevent rot. Water the plant regularly, especially during dry periods, to keep the soil consistently moist but not waterlogged.

Step 5: Pruning and Maintenance

A mountain laurel tree requires little maintenance once established. However, it may benefit from some light pruning in the late winter or early spring to remove any dead or damaged branches and promote healthy growth. Avoid heavy pruning, as this can remove too many flower buds and reduce the plant's overall beauty.

By following these simple steps, you can successfully plant a mountain laurel tree and enjoy its beautiful blooms for years to come.
