Light Requirements
The Crataegus fontanesiana plant prefers full sun or partially shade conditions. The plant can withstand direct sunlight, but it’s not mandatory for its growth. Partial shade contributes towards better flower and fruit productions.
Soil Requirements
The plant prefers well-drained soils with rich or loamy textures, which are slightly acidic. The pH level of the soil must range between 5.5 and 7.5. The plant can also withstand drought conditions, but moist soils are ideal for its growth and development. The plant can adapt well to sandy, clayey, or any other well-drained soil type.
Temperature Requirements
The Crataegus fontanesiana plant can adapt to a broad range of temperature conditions. The plant is cold tolerant and can withstand temperatures as low as -35 degrees Celsius. Summers with a temperature range between 20 to 30 degrees Celsius are ideal for the growth and development of the plant. The plant also thrives in mild to cool conditions with lower humidity levels.
Cultivation Methods
Crataegus fontanesiana (Spach) Steud. or the Mississippi Hawthorn is a beautiful deciduous tree that is cultivated for its lovely flowers and edible fruits. It is typically grown in USDA hardiness zones 6 through 9. To cultivate this plant, choose a site with well-draining soil and full sun to partial shade. The plant does well in acidic soils with a pH of 6.0 to 7.0. It is recommended to plant the tree in early spring or fall.
The planting hole should be twice as wide as the root ball and equally deep. Loosen the soil around the hole to allow for good root penetration. When planting, make sure the root collar or where the roots meet the trunk sits slightly above the soil surface. Water the tree thoroughly after planting.
Mississippi Hawthorn is a low-maintenance plant that tolerates a wide range of soils and environmental conditions. Once established, it can thrive with little attention.
Watering Needs
Mississippi Hawthorn needs regular watering, especially during the first year of growth. The soil should be kept consistently moist but not waterlogged. Overwatering may cause root rot, while under watering may stress the plant. During hot weather, the plant may need additional watering.
The best way to water the plant is by deep watering. This method involves watering the plant slowly and deeply, allowing the water to penetrate the soil to the roots. Once the soil reaches a depth of 6 to 8 inches, stop watering.
Fertilization
Fertilization is not necessary for Mississippi Hawthorn, but it can encourage growth and enhance the plant's health. If you choose to fertilize, do so in late winter or early spring before new growth appears. Use a balanced fertilizer with equal amounts of nitrogen, phosphorous, and potassium.
It is essential not to over-fertilize the plant, as this can lead to excessive growth, leaving the tree weak and more susceptible to pests and diseases.
Pruning
Mississippi Hawthorn requires minimum pruning, but occasionally you may need to trim it to maintain its shape and size. Pruning is best done during the dormant season or early spring before new growth appears.
When pruning, remove any damaged or dead wood and cut back any crossing branches that rub against each other. You can also remove any suckers that grow from the base of the tree. Prune just above the bud to encourage branching.
It is essential to prune lightly to avoid damaging the plant, as cutting back too much may cause it to produce fewer flowers. It is also important to sanitize your pruning tools to prevent the spread of diseases.
Propagation of Crataegus fontanesiana (Spach) Steud.
Crataegus fontanesiana can be propagated through seeds, cuttings, and grafting.
Propagation by Seeds
The seeds of Crataegus fontanesiana can be sown directly into the soil in fall or spring. It is important to stratify the seeds for about 90-120 days before sowing to break their dormancy. After sowing, the soil should be kept moist until the seeds germinate, which usually takes 1-2 months. The seedlings should be transplanted into individual containers or the ground once they are big enough to handle.
Propagation by Cuttings
Crataegus fontanesiana can also be propagated by softwood or hardwood cuttings. Softwood cuttings can be taken in late spring or early summer, while hardwood cuttings should be taken in winter. The cuttings should be about 6-8 inches long with several leaves removed from the bottom. The lower 1-2 inches of the cuttings should be dipped in rooting hormone and planted in well-draining soil with good moisture-retention capability. The cuttings should be kept in a humid environment and out of direct sunlight until they root, which usually takes 2-3 months.
Propagation by Grafting
Grafting is another method of propagating Crataegus fontanesiana. It involves attaching a scion (a piece of the desired plant) onto a rootstock (a different plant of the same genus). Grafting is usually done in winter or early spring when the plants are dormant. The scion should have two or three nodes, and a slanted cut should be made at the bottom. The rootstock, which should be of a similar diameter to the scion, should also be cut with a slanted cut. The two cuts should then be attached, and the grafted plant should be kept in a humid environment until it starts growing.
Disease and Pest Management for Crataegus fontanesiana
Crataegus fontanesiana, also known as the dotted hawthorn or Spach's hawthorn, is a popular flowering shrub that is native to North America. This plant is susceptible to a variety of pests and diseases that can impact its health and appearance. Here are some common diseases and pests that can affect Crataegus fontanesiana and how to manage them:
Leaf Spot
Leaf spot is a common fungal disease that affects many types of plants, including Crataegus fontanesiana. The symptoms of leaf spot include the formation of small, dark spots on the leaves that gradually grow larger and merge together. In severe cases, the leaves may turn yellow, wither, and fall off. To manage leaf spot, be sure to water the plant at the base and avoid getting moisture on the leaves. Remove any infected leaves as soon as possible and dispose of them in the trash.
Rust
Rust is another fungal disease that can affect Crataegus fontanesiana. Symptoms of rust include the formation of yellow or orange spots on the leaves, which eventually turn brown and may develop black spots in the center. Leaves infected with rust may also twist and distort. To manage rust, be sure to remove and dispose of any infected leaves. You can also apply a fungicide spray to help prevent the spread of the disease.
Aphids
Aphids are small, soft-bodied insects that can appear on Crataegus fontanesiana. They are usually found on the undersides of leaves and can cause leaf curling, stunted growth, and yellowing of the leaves. To manage aphids, you can either blast them off the plant with a strong stream of water or apply an insecticidal soap or oil spray. You can also encourage natural predators of aphids, such as ladybugs, lacewings, and parasitic wasps, by planting companion plants that attract them.
Scale Insects
Scale insects are small, sap-sucking pests that can appear on the bark and leaves of Crataegus fontanesiana. They are usually immobile and may appear as small bumps or waxy patches. Scale insects can cause yellowing of the leaves, stunted growth, and may even kill the plant if left untreated. To manage scale insects, you can prune and dispose of any heavily-infested branches or apply a horticultural oil spray. Encouraging natural predators, such as ladybugs and parasitic wasps, can also be effective.
Proper care and maintenance can go a long way in preventing diseases and pests from affecting Crataegus fontanesiana. This includes regular watering, fertilizing, pruning, and ensuring adequate sunlight. If you suspect your plant has a disease or pest infestation, it is best to take action as soon as possible to prevent it from spreading and causing further damage.
