Overview of Crataegus montivaga Sarg.
Crataegus montivaga Sarg. is a species of hawthorn that belongs to the Rosaceae family. This plant is endemic to the Appalachian Mountains in the eastern United States and grows primarily in the states of Virginia, West Virginia, and North Carolina. It is commonly known as Mountain Hawthorn, which refers to its natural habitat and its growth on rocky outcroppings and slopes.
Description of Crataegus montivaga Sarg.
Crataegus montivaga Sarg. is a small, deciduous shrub that can reach up to 6 feet in height. It has a dense, upright growth habit and a rounded shape. The foliage of the plant is dark green and leathery, with deeply lobed leaves that are up to 2 inches long. In the fall, the leaves turn a bright yellow-orange color before dropping off.
The plant produces clusters of small, white flowers in the late spring. These flowers give way to small, round berries that are bright red in color. These berries are a valuable source of food for birds and other wildlife.

Overall, Crataegus montivaga Sarg. is a versatile plant with a number of uses and an attractive appearance. Its hardiness and adaptability make it a great choice for gardeners looking for a low-maintenance, yet visually striking plant.
Light Requirements
Crataegus montivaga Sarg. typically prefers full sun to partial shade. The plant can tolerate direct sunlight during cooler hours of the day, but high temperatures during summer may cause leaf scorching.
Temperature Requirements
The plant is native to the mountain regions of Korea, demonstrating an adapatability to a cooler climate. However, it can grow well in a range of moderate temperatures between 20°C and 25°C (68°F - 77°F). During winters, the plant may shed leaves and become dormant, indicating a preference for cool-cold weather.
Soil Requirements
Crataegus montivaga Sarg. prefers well-drained, medium-textured soils with a slightly acidic to neutral pH. It can tolerate soils with slightly elevated salt levels but will not thrive in poorly drained soils or heavy clay soils. A fertile soil enriched with organic matter can benefit the plant's growth.
Cultivation Methods
Crataegus montivaga Sarg., commonly known as the mountain hawthorn, is a deciduous shrub that is indigenous to the southeastern United States. To cultivate this plant, start by selecting a well-draining soil with a pH between 5.5 and 7.5. You can propagate the mountain hawthorn through seeds or cuttings, and it's best to plant during the spring or fall.
Choose a location that offers full sun exposure, although the mountain hawthorn can tolerate partial shade. It prefers moist soil, so make sure to water regularly and mulch around the base of the plant. Be aware that this plant can spread out aggressively, so it's advisable to plant it in a location where it can grow without disturbing other plants.
Watering Needs
Crataegus montivaga Sarg., or Mountain hawthorn, require consistent watering throughout the warmer months. For optimal plant health and productivity, saturate the soil to 6 to 8 inches deep. It is best to water the plant thoroughly once a week, rather than lightly each day. This helps the roots to develop smoothly with an ample mix of water and oxygen. However, it's crucial to avoid over-watering as this can lead to root rot and cause the plant to wilt or die.
Fertilization
Mountain hawthorns do not require fertilizer often. It's best to feed the plant once every two years to avoid excessive growth and maintain a healthy root system. If you need to fertilizer your plant, use a balanced fertilizer, such as a 10-10-10 mix in early spring. It's essential to follow the instructions provided with the specific fertilizer brand to avoid overfeeding.
Pruning
Mountain hawthorns require only minimal pruning to maintain their shape and size. It's best to conduct pruning in late winter before the growth season starts. Start by removing any dead, damaged or diseased branches. Then remove any branches that are crossing or rubbing other branches. Trim back any branching that is growing beyond the desired shape or density. Avoid pruning more than 1/3 of the plant's height or width to avoid damaging the main stem.
Propagation of Crataegus montivaga Sarg.
Crataegus montivaga Sarg. or "Mountain hawthorn" can be propagated using various methods. Some of the commonly used propagation methods are discussed below:
Seed Propagation
Mountain hawthorn can be propagated from seeds. The seeds can be collected from ripe berries in the fall season. The seeds should be washed and allowed to dry for a few days. Seeds can be treated with a fungicide before sowing to prevent fungal infections. Germination can be improved by cold stratification. The stratified seeds can be sown in a well-draining seed-starting medium. They should be kept moist and in a warm, bright location. Seedlings can be transplanted once they have developed roots and leaves.
Cuttings Propagation
Mountain hawthorn can also be propagated from cuttings. Hardwood cuttings from mature plants can be collected in the winter season. The cuttings should be about 6-8 inches long with 2-3 nodes. The leaves should be removed from the lower part of the cutting. The cuttings should be dipped in a rooting hormone and planted in a well-draining medium. They should be kept moist and in a warm, bright location. Once the cutting has rooted and developed new leaves, it can be transplanted to a larger container.
Grafting Propagation
Grafting is another propagation method for Mountain hawthorn. The scion of a desirable cultivar can be grafted onto a rootstock of a closely related species. The graft union should be wrapped with a grafting tape or paraffin to discourage desiccation. Once the graft has taken hold, the rootstock should be pruned off above the graft union. The grafted plant can be transplanted into the ground or to a container.
Disease Management for Crataegus montivaga Sarg.
Crataegus montivaga Sarg. is relatively resistant to many diseases, but some fungal infections can occur, particularly in humid environments and on stressed plants.
One common disease that can afflict Crataegus montivaga Sarg. is cedar-hawthorn rust, caused by the fungus Gymnosporangium globosum. Symptoms include yellow-orange spots on the leaves, which can lead to premature leaf drop and reduced growth. Management of cedar-hawthorn rust involves a combination of cultural control and chemical management. Cultural controls include removing infected leaves and maintaining good tree health through proper watering and fertilization. Chemical control involves applying fungicides according to the product label instructions.
Fire blight, caused by the bacterium Erwinia amylovora, can also infect Crataegus montivaga Sarg. Symptoms include blackened leaves and shoots that curl into a shepherd's crook shape. To manage fire blight, remove infected plant material and promptly destroy it. Prune trees in late winter or early spring to help prevent buildup of the bacteria and improve air circulation. Antibiotics can also be used for chemical control, but this method should be used sparingly to avoid the development of antibiotic-resistant strains.
Pest Management for Crataegus montivaga Sarg.
Crataegus montivaga Sarg. is susceptible to pests such as aphids, scale insects, and spider mites. These pests can cause direct damage to the plant by feeding on the leaves and stems, and can also act as vectors for diseases.
Aphids are small, soft-bodied insects that feed on the sap of the plant, causing distorted growth and yellowing leaves. To manage aphids, use non-toxic insecticidal soaps or oils, or introduce natural predators such as ladybugs or lacewings. Scale insects are hard, shell-like pests that attach themselves to the leaves and stems of the plant, sucking out the sap. Management of scale insects also involves the use of non-toxic insecticidal soaps or oils, as well as manually removing the scales with a soft brush or cotton swab. Spider mites are tiny, spider-like pests that feed on the underside of leaves, causing yellowing and bronzing of the leaves. To manage spider mites, increase humidity around the plant, use non-toxic insecticidal soaps or oils, or introduce natural predators such as predatory mites.
Regular monitoring of the plant for signs of infestation is key to pest management. If caught early, infestations can often be controlled using non-toxic methods before causing significant damage to the plant.
