How to Plant Mountain Laurel: Choose the Right Location

Before you start planting, it’s crucial to choose the right location for your mountain laurel. These plants thrive in well-drained, acidic soils with a pH between 4.5 and 6.0. Ensure the area receives partial to full sun, with a few hours of shade in the afternoon to protect the plant from the hot sun.

If you live in a region with heavy clay or alkaline soil, you may need to amend the soil and improve drainage. Before planting, test the soil pH with a soil test kit from a local garden center or nursery. If the pH is too high, add organic matter to acidify the soil, such as peat moss, compost, or sulfur.

Ensure the soil has good drainage, as mountain laurels do not tolerate standing water. If necessary, improve drainage by adding coarse sand or perlite to the soil. Dig a hole twice as wide as the root ball and the same depth as the root ball to provide enough space for the roots to grow.

Mountain Laurel Planting Tips

Before planting, ensure the soil is fertile and well-draining. Remove any rocks or debris from the planting hole, and mix in a generous amount of organic matter, such as compost or aged manure, to provide the plant with essential nutrients.

To improve drainage, you can add sand or perlite. Mix the soil amendment well with the existing soil, and fill the planting hole with the mixture.

Water the soil before planting to ensure it’s thoroughly moist but not waterlogged. This will help the plant establish quickly.

Prepare the Soil for Planting

Proper soil preparation is key to the success of your mountain laurel. The first step is to test your soil’s pH level. Mountain laurels prefer acidic soil with a pH between 4.5 and 6.0. If your soil’s pH is too high, you can lower it by adding soil sulfur or organic matter like peat moss.

It’s also important to ensure good drainage to prevent waterlogging, which can lead to root rot. If your soil doesn’t drain well, consider adding sand or compost to improve drainage.

Next, remove any weeds, rocks, or debris from the planting area. Dig a hole that’s twice as wide and as deep as the root ball of your mountain laurel. Place the plant in the hole, making sure the top of the root ball is level with the ground. Fill in the hole with soil, gently tamping it down with your foot as you go to prevent air pockets.

Your mountain laurel is now ready for mulching and watering. In the next section, we’ll go over the best practices for mulching and watering to ensure the health and growth of your plant.

Mountain Laurel Planting Guide

Now that you have chosen the right location and prepared the soil, it’s time to plant your mountain laurel. Follow these steps for optimal results:

  1. Firstly, dig a hole that is just as deep as the root ball of your mountain laurel, but twice as wide.
  2. Gently remove the plant from the container and loosen any tangled roots.
  3. Place the plant in the center of the hole and backfill with the soil mixture. Gently tamp the soil around the base of the plant to remove any air pockets.
  4. Water your mountain laurel thoroughly, providing enough water to moisten the soil at the base of the plant. Avoid overwatering, which can lead to root rot.
  5. Finally, add a layer of organic mulch around the base of the plant, taking care not to cover the stem or leaves. This will help retain moisture and plant nutrients while inhibiting weed growth.

To maximize the growth and health of your mountain laurel, it’s important to water it regularly, particularly during dry spells. However, be careful not to overwater the plant, which can lead to root rot. In addition, monitor for pests and diseases, and address any issues promptly to prevent them from spreading.

Planting Depth and Spacing

When planting mountain laurel, ensure that the top of the root ball is level with the surrounding soil. Planting too deep can lead to root suffocation and poor growth. Leave at least six feet between each plant to allow for proper airflow and reduce the risk of disease.

Growing Mountain Laurel: Mulching and Watering

Mountain laurel requires consistent moisture to thrive, especially during its first year of growth. After planting, water your mountain laurel regularly, aiming to keep the soil moist but not waterlogged.

Once your mountain laurel is established, mulching can help conserve moisture and regulate soil temperature. Apply a layer of organic mulch around the base of the plant, taking care not to cover the stem. This will also help control weeds and enrich the soil as it decomposes.

When watering, avoid getting the foliage wet as this can lead to disease. Instead, use a soaker hose or drip irrigation to water at the base of the plant for optimal absorption.

Be sure to monitor the moisture levels of your mountain laurel, especially during periods of drought or heavy rain. Adjust your watering schedule accordingly, taking care not to overwater which can lead to root rot and other issues.

Mountain Laurel Care Guide

Caring for your mountain laurel is easy and straightforward. With just a few simple steps, you can ensure your plant remains healthy and thriving for years to come.


Regular pruning is important to maintain the shape and vigor of your mountain laurel. It’s best to prune in the late spring or early summer, after the plant has finished blooming. To promote a bushy, compact growth habit, pinch back the tips of new growth in the spring.

When pruning, remove any dead or damaged branches, as well as any crossing or rubbing branches. Cut just above a leaf node, making sure not to leave a stub. Avoid pruning too much at once, as this can cause stress to the plant.


Mountain laurel does not require much fertilizer, but a light application in the spring can help promote healthy growth and blooming. Use a slow-release fertilizer, following package instructions for application rates.

Pest and Disease Management

Mountain laurel is generally resistant to pests and diseases, but occasional issues can arise. Spider mites, lace bugs, and scale insects can be treated with insecticidal soap or horticultural oil. Powdery mildew and leaf spot can be prevented by providing good air circulation around the plant and avoiding overhead watering.

Protecting from Winter Damage

In colder regions, it’s important to protect your mountain laurel from winter damage. Apply a thick layer of mulch around the plant’s base to insulate the roots from cold temperatures. Avoid pruning in the fall, as this can stimulate new growth that is vulnerable to winter damage.

  • Regular pruning promotes healthy growth and a compact shape.
  • A light application of slow-release fertilizer in the spring can enhance growth and blooming.
  • Pests and diseases can be treated with insecticidal soap or horticultural oil.
  • Winter protection involves adding a layer of mulch around the plant’s base and avoiding fall pruning.

Common Issues and Troubleshooting

Despite your efforts, you may encounter some issues with your mountain laurel. Here are a few common problems and how to troubleshoot them:

Yellowing Leaves

If you notice yellow leaves on your mountain laurel, it could be a sign of several issues. One common cause is overwatering, which can cause root rot. Check the soil moisture level and adjust your watering accordingly. Another possible cause could be nutrient deficiencies, in which case fertilizing with a balanced, slow-release fertilizer may help.

Pest Infestations

Mountain laurel can attract pests such as lace bugs and spider mites. Regularly inspect your plant for signs of damage, and treat any infestations with insecticidal soap or neem oil. Avoid using broad-spectrum pesticides, as they can harm beneficial insects and pollinators.


Mountain laurel can be susceptible to diseases such as leaf spot and phytophthora root rot. To prevent these diseases, ensure proper drainage and avoid overwatering. If you notice signs of disease, remove affected leaves or branches and treat with a fungicide if necessary.

Pruning and Shaping Your Mountain Laurel

Proper pruning is essential for the shape and health of your mountain laurel. Pruning should be done in late winter or early spring, before new growth starts. Follow these steps:

  1. Remove any dead or damaged branches.
  2. Thin out crowded or crossing branches to improve air circulation and sunlight penetration.
  3. Shape the plant by selectively cutting back branches to encourage fullness and a pleasing form.
  4. Remove spent flowers to promote new growth and prevent disease.

When pruning, avoid cutting into the woody parts of the plant, which can damage it and impede future growth. Use sharp, clean pruning shears and sanitize after each use to prevent the spread of disease.

To maintain a specific shape or size, you can use shaping techniques:

American gardeners have used “cabbageing” to great effect on mountain laurel: once shrubs are established, cut one-third to one-half of the stem or branch tips back each year for a few years to encourage dense foliage and a rounded shape. This treatment will retard bloom the first year followed by many weeks of color thereafter. – Michael A. Dirr, The Reference Manual of Woody Plant Propagation

When shaping, take care not to remove too much foliage, which can harm the plant’s health. Regular pruning and shaping will keep your mountain laurel healthy, beautiful, and thriving.

Propagating Mountain Laurel

If you want to expand your mountain laurel collection, propagation is an excellent option. You can propagate mountain laurel using seeds, stem cuttings, or layering. Here’s a step-by-step guide on seed propagation.

  1. Collect seeds from a mature mountain laurel in the fall. The seeds will be in small pods, which will need to dry out and split to release the seeds.
  2. Stratify the seeds by placing them in a plastic bag filled with moist sand or peat moss and storing them in the refrigerator for 60 to 90 days.
  3. Fill a container with a well-draining potting mix and sprinkle the stratified seeds on top. Don’t bury the seeds too deeply as they need light to germinate.
  4. Mist the soil with water and cover the container with plastic wrap to create a greenhouse effect.
  5. Place the container in a warm, bright location but out of direct sunlight. Keep the soil moist but not soggy.
  6. After 4-6 weeks, the seeds will start to germinate. Remove the plastic wrap and place the container in a bright, sunny location.
  7. When the seedlings are a few inches tall, transplant them into individual pots and continue to care for them until they are large enough to be planted outdoors.

Propagation can take time and patience, but it is a rewarding process that can add to the beauty of your garden and provide an opportunity to share your mountain laurel with others.
