Mountain Laurel Growing: Care Of Mountain Laurel In The Landscape<\/h1>\n

If you have typical Brooklyn clay soil in your garden, you’ll want to create a nurturing environment for mountain laurel by improving drainage and nutrient content with organic matter such as compost. This shrub needs its shallow roots to stay cool, so mulch and keep your plant well-watered, especially during very hot, dry weather. An organic fertilizer like Holly-Tone, which is formulated for acid-loving plants, can be applied in the spring to enhance flower production.<\/p><\/blockquote>\n

Mountain Laurel: A Shade-Tolerant Native With Beautiful Blossoms<\/h2>\n

<\/p>\n

When it comes to spectacular flowers, most city gardeners have limited choices. The narrow plots typically found behind most brownstones and row houses get little light due to neighboring trees and adjacent buildings, so using showy plants that require hours of full sun is not realistic.<\/p>\n

One often overlooked option is mountain laurel (Kalmia latifolia<\/em>). This shade-tolerant North American shrub has gorgeous flowers that bloom in late spring and early summer. A close relative of rhododendrons and azaleas, it\u2019s an excellent choice for a shady garden. It\u2019s also evergreen, so even after the blooms have faded, its leathery deep green foliage provides a welcome sign of life. Even in the coldest winter weather, when rhododendron leaves have curled in on themselves, mountain laurel remains bravely open to the elements.<\/p>\n

Why Is It So Special?<\/h2>\n

In addition to being tolerant of shade, Kalmia latifolia<\/em> produces exquisite clusters of delicate, fused-petal blossoms that resemble tiny origami rice bowls. When the buds burst open in May or June, the branches are virtually obscured by blooms. They can range from white to pink to deep rose and are distinctively tattooed with symmetrical maroon or purple dots or streaks. The bell-like flowers have a very unusual way of dispensing pollen. Their stamens are arched, with the tips held under the rim of the bell. When a bee or other pollinator lands on the flower, the weight of the insect releases the stamen, which flings up the pollen like a catapult.<\/p>\n

Cultivation<\/h2>\n

Mountain laurel is a member of the heath or heather family, Ericaceae. This family includes rhododendrons, azaleas, blueberries, and cranberries, all of which are woody shrubs that thrive in moist, well-drained acidic soil. Mountain laurel will grow in USDA Zones 5 to 9 in deep shade to full sun, but it does best in moderate to partial shade. In deep shade it won’t produce as many flowers and can become spindly. Too-bright sun can cause scorching of the leaves.<\/p>\n

If you have typical Brooklyn clay soil in your garden, you’ll want to create a nurturing environment for mountain laurel by improving drainage and nutrient content with organic matter such as compost. This shrub needs its shallow roots to stay cool, so mulch and keep your plant well-watered, especially during very hot, dry weather. An organic fertilizer like Holly-Tone, which is formulated for acid-loving plants, can be applied in the spring to enhance flower production.<\/p>\n

Maintenance<\/h2>\n

An individual mountain laurel shrub can produce thousands of seeds annually. It\u2019s a good idea to pinch off spent flowers so the plant can put its energy into next year\u2019s blooms instead of reproduction. Deadheading also helps to prevent legginess. Mountain laurel is slow growing, and at maturity, it averages 6 to 15 feet in height and width; dwarf cultivars top out at 3 to 4 feet.<\/p>\n

Although mountain laurel in the wild has been known to reach heights of 20 to 40 feet, there’s usually little need for pruning. If your plant is growing too tall for your garden, it will survive hard pruning\u2014even to a few inches above the ground\u2014in the late winter or early spring. Given proper growing conditions, mountain laurel requires little maintenance beyond regular watering, but it can still sometimes fall victim to common garden ills such as blights, borers, scale, white fly, and lace bugs.<\/p>\n

A word of caution, especially if your garden is visited by children or pets. All parts of Kalmia latifolia<\/em> are poisonous if ingested and can cause severe digestive upset and other alarming, though usually nonfatal, symptoms such as weakness and paralysis. Not all animals are affected\u2014deer, unfortunately, are apparently immune to any ill effects and can be vigorous consumers of mountain laurel foliage.<\/p>\n

Where to Find Mountain Laurel<\/h2>\n

Mountain laurel was first recorded growing in the wild in 1624 and can be found on rocky ridges and mountainous forest areas as far south as the Florida Panhandle, as far north as southern Quebec, and as far west as Indiana and Louisiana. In spring it can be seen blooming abundantly along the Blue Ridge Parkway in North Carolina and, closer to New York City, in the forests of upstate New York, notably near Lake Minnewaska, in Ulster County. It is the state flower of both Connecticut and Pennsylvania.<\/p>\n

Mountain laurel is also part of the amazing flower display that takes place at Brooklyn Botanic Garden every spring and can be found in the Discovery Garden, Japanese Hill-and-Pond Garden, and Native Flora Garden.<\/p>\n

      Mountain Laurel Growing: Care Of Mountain Laurel In The Landscape<\/h2>\n

      \"Close<\/p>\n

      Grown for its showy late spring and summer flowers and attractive, evergreen foliage, mountain laurel (Kalmia latifolia<\/em>, USDA zones 5 through 9) is a colorful asset to borders and foundation plantings, and it looks fantastic in mass plantings. It\u2019s sometimes called a calico bush because the pink or white flowers usually have dark pink or maroon markings. Native to the eastern U.S., you can often find mountain laurel growing wild among native azaleas and rhododendrons.<\/p>\n

      Mountain Laurel Information<\/h2>\n

      You\u2019ll find many lovely cultivars of mountain laurel to choose from, thanks in large part to Dr. Richard A. Jaynes of Hamden, Connecticut. Here are just a few of his enticing creations:<\/p>\n

        \n
      • \u2018Elf\u2019 is a dwarf that grows 3 feet (1 m.) tall with pale pink or white blossoms.<\/li>\n
      • \u2018Heart of Fire\u2019 has deep red buds that open to pink flowers with dark pink edges on a 5 foot (1.5 m.) shrub.<\/li>\n
      • \u2018Raspberry Glow\u2019 grows up to 6 feet (2 m.) tall. The burgundy buds open to raspberry pink flowers that keep their color when grown in shade.<\/li>\n
      • \u2018Carol\u2019 forms a low, rounded mound of dark green foliage. The buds are red and the flowers are bright white.<\/li>\n
      • \u2018Snowdrift\u2019 has white blooms with a dab of red in the center. It grows about 4 feet (1 m.) tall.<\/li>\n<\/ul>\n

        How to Grow a Mountain Laurel<\/h2>\n

        Mountain laurel looks best when grown in dappled sunlight, but it also grows well in full sun or partial shade. Avoid locations with full sun in combination with reflected light from heat-reflecting southern or southwestern walls. Partial shade is best in hot, southern climates. In deep shade the flowers lose their bright colors and may develop leaf spot.<\/p>\n

        If azaleas and rhododendrons grow well in the area, mountain laurel will thrive. The shrubs need moist but well-drained, acidic soil. They won\u2019t grow well in clay soil. It\u2019s important not to give the shrubs too much fertilizer, so don\u2019t plant them in or near lawns fed with high-nitrogen products.<\/p>\n

        Care of Mountain Laurel<\/h2>\n

        Amend the soil with compost when planting mountain laurels. If you have several shrubs, amend the entire bed. Add the compost to the fill dirt if you are only planting one or two shrubs. When adding organic matter to the fill dirt, dig the hole as deep as the root ball and three times as wide so the shrub will have plenty of organic soil where it can spread its roots.<\/p>\n

        Mountain laurel has a shallow root system and needs watering more often than most shrubs. New plantings need 2 inches (5 cm.) of water each week for the first season. The average sprinkler system delivers about an inch (2.5 cm.) of water per hour, so you\u2019ll need to run the system two hours. Use organic mulch, such as pine needles or shredded bark, to help the soil hold moisture between waterings.<\/p>\n

        These shrubs don\u2019t need a lot of fertilizer and may bloom poorly if you apply too much. Use a fertilizer designed for acid-loving plants mixed at one-quarter strength once a year in spring. You can also add a thin layer of compost to the soil for additional nutrients and to add to the organic matter of the soil.<\/p>\n

        Mountain laurel begins forming the buds for next year\u2019s flowers soon after the flowers fade. Prune the shrub right after flowering so that you don\u2019t remove the new buds. Cut off faded flowers promptly so the shrub can focus its energy on growth rather than seed development.<\/p>\n","protected":false},"excerpt":{"rendered":"
