Gaultheria Nummularioides

Overview

Gaultheria nummularioides is a low-growing evergreen shrub that belongs to the family Ericaceae. It is widespread in the Northern Hemisphere, found in North America and Asia.

Common Names

The plant is commonly known as Little Mountain Cranberry or Kinnikinnik. It is also referred to as Bearberry, although that name also applies to other species of shrubs.

Appearance

Gaultheria nummularioides grows up to 20cm in height with a dense growth habit, spreading by underground stems called ‘rhizomes’. The leaves are small, oval in shape, dark green, and shiny on the upper side while paler underneath. The flowers are small and white, bell-shaped and produced in late spring to early summer, followed by bright red, edible berries about the size of a cranberry. The plant has an average lifespan of 20-30 years.

Uses

The plant has many uses, both ornamental and practical. It is used for decorative purposes in landscaping due to its appealing foliage and berries, as well as for erosion control. The berries are a food source for birds and wildlife. Indigenous peoples used the leaves in traditional medicine to treat a variety of ailments, including colds, fevers, and gastrointestinal disorders. The leaves are also used in herbal tea and to flavor tobacco in some cultures. Gaultheria nummularioides extract is used in some cosmetics and skin care products due to its high content of flavonoids, which have antioxidant properties.

Light Requirements

Gaultheria nummularioides requires partial shade or full shade for optimal growth. It cannot tolerate direct sunlight or extended periods of exposure to direct sunlight. It is recommended that this plant be grown under trees or other plants that provide partial shade. Direct sunlight can cause leaf scorch and sun damage.

Temperature Requirements

Gaultheria nummularioides grows best in cool temperatures, which is why it is native to the mountains of South America. The ideal temperature range for growth is between 10°C to 20°C (50°F to 68°F). It can tolerate brief temperature drops to 1°C (34°F) but cannot survive in constant freezing temperatures. It is important to protect this plant from harsh winter winds that can cause desiccation and leaf damage.

Soil Requirements

Gaultheria nummularioides requires well-drained (but not dry) soil that is rich in organic matter. Ideal soil pH is between 5-7.5. It can tolerate mildly acidic to slightly alkaline soils. Freshly grown soil with high organic matter content is ideal, especially a mix of humus, peat and sand. The plant also benefits from a regular fertilization schedule during the growing season with a balanced fertilizer or slow-release organic fertilizer.

Cultivation Methods

Gaultheria nummularioides, also known as the coinleaf wintergreen, can be propagated through seeds or cuttings. It prefers well-drained, acidic soil with a pH of 4.5 to 6.0. This plant thrives in a partially shaded location, with at least 3 hours of sunlight per day. It can grow up to 6 inches in height and spread up to 2 feet, so enough space should be provided between plants.

Watering Needs

Gaultheria nummularioides likes to stay consistently moist, but not waterlogged. It is susceptible to root rot, so do not let the soil dry out completely. Water it regularly during the growing season and reduce watering during the winter months.

Fertilization

It is recommended to fertilize Gaultheria nummularioides once a year during spring using a slow-release fertilizer designed for acid-loving plants. Follow the manufacturer's instructions for proper application and dosage. Over-fertilization can cause leaf burn, so beware of excessive amounts.

Pruning

Gaultheria nummularioides does not require much pruning, but it can benefit from being trimmed in late winter or early spring before new growth emerges. This will remove any dead or damaged branches and promote bushier growth. Avoid heavy pruning as this can affect the plant's overall health and appearance.

Propagation Methods for Gaultheria nummularioides

Gaultheria nummularioides, commonly known as dollar-leaf snowberry or silverleaf snowberry, is a low-growing evergreen plant that belongs to the heath family. It is native to Western North American mountains and is commonly found in moist and shady areas. If you are interested in propagating this attractive plant, several methods can be used.

Propagation by Seeds

Propagation using seeds is a cost-effective way to get new plants. You can harvest seeds from the plant itself or purchase seeds from a reputable seller. Here are the steps for propagation by seeds:

1. Begin by soaking the seeds in water for a few hours to soften their tough outer layer.
2. Fill a seed tray with a good quality seed starting mix and moisten it.
3. Spread the seeds uniformly over the soil surface and cover them with a thin layer of soil mix.
4. Keep the tray in a warm location with indirect sunlight and ensure that the soil mix stays moist.
5. The seeds usually germinate in 3-4 weeks, and you can transplant them to individual pots or into your garden bed.

Propagation by Stem Cuttings

Propagation using stem cuttings is a quick way to get new plants that will be identical to the parent plant. Here are the steps for propagation by stem cuttings:

1. Cut a few inches long healthy stems that do not have flowers or buds.
2. Remove the lower leaves from the stem, leaving only a few leaves on top.
3. Dip the cut end of the stem in rooting hormone and insert it into a rooting medium such as a soilless mix or sand.
4. Mist the cutting regularly to keep it moist and keep it in a shaded area away from direct sunlight.
5. After a few weeks, the stem will begin to root, and you can transfer it to a larger pot or your garden bed.

Propagation by Division

Propagation by division is a straightforward method used for mature plants. Here are the steps for propagation by division:

1. Dig up the mature plant in the fall or early spring when the plant is dormant. You must have a well-established clump with at least three to four plants.
2. Shake off the soil to get a better view of the root system.
3. Use a clean, sharp knife to separate the clump into individual sections, ensuring that each section has both roots and leaves.
4. Plant each new section into its own pot or directly into your garden bed.

By using these propagation methods, you can easily add more Gaultheria nummularioides plants to your collection or garden.

Disease and Pest Management for Gaultheria nummularioides

Gaultheria nummularioides, commonly known as Moxie Plum or Sierra Wintergreen, is a low-growing, evergreen ground cover plant that is native to the western United States. Like any other plant, it is susceptible to certain diseases and pests that can cause damage to it. Here are some common diseases and pests that might affect the plant and some ways to manage them:

Diseases

1. Phytophthora Root Rot: Phytophthora is a soil-borne pathogen that attacks the roots of the plant, causing them to rot. Symptoms of root rot include wilting, yellowing leaves, and stunted growth. To manage this disease, ensure that the soil is well-drained and avoid overwatering the plants. You can also use fungicides to control the disease.

2. Leaf Spot: Leaf spot is a common fungal disease that causes circular or irregular-shaped spots on the leaves of the plant. The spots might appear yellow, brown, or black, and they might have a halo around them. To manage this disease, ensure that the plant is growing in well-drained soil and avoid overhead watering, as this can promote the growth of the fungus. You can also use fungicides to control the disease.

Pests

1. Spider Mites: Spider mites are tiny pests that feed on the foliage of the plant, causing yellowing and stippling of the leaves. They thrive in hot, dry weather conditions. To manage spider mites, use insecticidal soap or neem oil to spray the plant and keep it well-watered.

2. Aphids: Aphids are small, soft-bodied insects that suck the sap from the plant, causing stunted growth and yellowing leaves. They secrete a sticky substance called honeydew, which can attract ants. To manage aphids, spray the plants with a strong jet of water to knock them off. You can also use insecticidal soap or neem oil to control the pests.

By monitoring your Gaultheria nummularioides plant regularly and keeping it healthy, you can prevent diseases and pests from causing any serious damage to it.
