    How To Grow Mountain Laurel?

    How To Grow Mountain Laurel?

    Mountain laurel belongs to the heather family, Ericaceae. Rhododendrons are also a part of this family, and just like them, mountain laurel prefers moist and acidic soil.

    • Mountain laurel is ideally planted in moderate to partial shade. However, in deep shade and fully sunny areas, they don’t produce many flowers and manage to barely survive.
    • Plant these shrubs 4 to 6 feet apart, but not too deep. While planting a mountain laurel farm, you must make sure the shrub’s crown is not buried or else they will rot and die.
    • These shrubs prefer acidic soils and don’t thrive in heavy clay soils. To adjust the pH level in your soil and make it suitable for the shrubs, you can improve the drainage and try adding organic matter.
    • You must water your plants well especially in extreme summers as this shrub has shallow roots that prefer to stay cool.
    • You can also apply organic fertilizers in spring to boost mountain laurel flower production as this is a shrub that appreciates acidic soil.

    It is better to keep the soil moist initially as afterward they develop a good tolerance to drought as well. But for Mountain laurel to thrive, keep the soil cool and provide shade during warmer months.

    Although gardeners are careful when they are growing this shrub perennially, animals should not be allowed near these shrubs.

    1. Broadly, this shrub can be affected by weather injuries and fungal or bacterial infections. While some of these causes are individual incidents, others can spread rapidly to more plants if not given proper attention at the right time. 
    2. The most common problem with mountain laurels is the damage from extreme weather conditions. As this is an evergreen shrub that carries foliage during winter, it can get damaged by harsh cold temperatures.
    3. Also in extreme winters with heavy snow and winds, you can observe broken branches and signs of browning leaves.
    4. It is essential at this point that these broken and dead parts of the shrub be removed at the earliest to prevent any disease from pests. So, the plants should be cleared so that they can recover themselves in spring.
    5. On the other end of extreme weather, Mountain laurel shrub is also susceptible to drought. Drooping or browning of leaves and sometimes cracked stems can be observed in dry weather.
    6. Drought-stressed plants can get even further affected by parasitic organisms. Therefore, it is advised to water mountain laurels properly throughout the growing season.
    7. These shrubs can also fall victim to fungal infections and blight. Gardeners often look for leaf spots which are the occurrence of dark “spots” on the leaves.

    Although the infected leaves mostly fall off the plant, they need to be removed from the garden to prevent further spread of the infection. With proper garden maintenance with regular inspections and clean-ups, the leaf spot problem can be easily kept in check.

    When Does Mountain Laurel Bloom?

    The blooming season of mountain laurel depends on elevation and latitude. The lower the elevation and latitude, the earlier you observe them blooming.

    These shrubs usually bloom between mid-April to the end of the summer solstice. In the Deep South of USDA Zone 8, blooming usually begins in mid-April and peaks just before the first week of May.

    In zone 7, blooming begins around the first week of May and peaks in the second week. However, in higher elevations north of zone 6, blooming peaks in middle to late May, and well into early June in areas at an even higher elevation.

    The precise timing of mountain laurel blooming depends on seasonal weather trends every year. Although average flowering time can be estimated for different regions, a cool, wet, and cloudy spring can delay the flowering period by one or two weeks.

    On the other hand, an unexpectedly warm spring with too much sun can bring the flowering season early by one or two weeks.

    Once these shrubs begin flowering, the ideal temperatures between 50 and 75 F make them last for long. Warm weather wind and heavy showers shorten the blooming span of flowers.

    Mountain Laurel Tree Care Tips

    Though this shrub can adapt to most weather conditions, we still have some tips to create a more suitable environment for the mountain laurel tree:

    • Plant them in well-drained, moist, and acidic soil to enhance their flowering season
    • Ensure proper drainage to prevent them from rotting. You can even opt for planting them in raised beds if drainage is an issue.
    • Mountain laurel grows best in partial shade. It produces limited flowers in too much shade while the too-bright sun can result in scorching of the leaves.
    • Immediately removing spent blooms will significantly enhance the following year’s flower production.
    • Though mountain laurel requires limited pruning, if your plant does tend to overgrow, you can prune it just after flowering down to a few inches from ground level. It will grow again but at a slow pace over a few years.

    Mountain Laurel VS. Rhododendron

    Mountain Laurel and Rhododendron (Rosebay) are evergreen shrubs spotted growing close to each other in forests of the eastern United States. When they are not blooming for most of the year, how can you identify them?

    Though the oblong leaves are common to both, you will notice that the underside of the leaves creates the distinction. While Mountain laurel leaves are smooth and have a paler shade of green compared to the top side, Rhododendron’s leaves have an additional brown fuzz to their paler shade of green.

    Another distinction observed in mountain laurel pictures is that their leaves curl upward along the edges, while Rhododendron’s leaf edges are downward.

    Lastly, one more distinction is that Rhododendron leaves are longer when compared with Mountain laurel leaves.

    How Poisonous Is Mountain Laurel?

    The poison of the mountain laurel is in every part of the plant (especially in the young shoots and leaves) so it is recommended to keep them away from children and animals.

    The gorgeous flowers of this shrub attract the children with a sweet aroma. Children often suck on the sweet liquid in the nectar which can lead to vomiting, stomach pains, and a runny nose.

    The mountain laurel leaves are equally harmful as the flowers and can make the animals severely ill and even lead to death if they feed on them. These leaves can cause convulsions, difficulty with breathing, and drooling in animals such as goats, horses, or sheep.

    Most gardeners are careful when dealing with this shrub and the only instances of poisoning that caused mild illness is due to the ingestion of honey made by bees who fed on their flower’s nectars.  

    However, if a person is already suffering from health issues, then the ingestion can lead to a quick death as well. These shrubs contain Andromeda toxins which significantly lower blood pressure.

    This leads to drowsiness and sometimes convulsions. In some severe cases, death is also seen to be preceded by a type of paralysis.
