Crataegus calpodendron var. hispida grows best in areas with full sun exposure. The plant can tolerate some shade, but it is not recommended to grow it in shaded areas as it can negatively affect growth.
Temperature Requirements
The plant is native to the eastern part of the United States and prefers moderate temperatures for optimal growth. Crataegus calpodendron var. hispida can tolerate cold weather conditions but does not do well in extreme heat. Temperatures between 60-75°F are ideal for this plant.
Soil Requirements
Crataegus calpodendron var. hispida prefers well-draining soils with a pH range between 6.5 and 7.5. The plant can tolerate different soil types such as loam, clay, or sandy soils but performs best in loamy soils. The plant thrives in soils that are rich in organic matter and has good air circulation.
Cultivation Methods
Crataegus calpodendron (Ehrh.) Medik. var. hispida (Sarg.) Palmer, commonly known as the hawthorn tree, is a hardy plant that can tolerate different soil types, including clay, loam, and sandy soils. The plant prefers full sunlight but can also thrive in partial shade. When planting, ensure that the soil is well-draining, and the planting hole is twice the size of the root ball. Hawthorn trees grow slowly and can reach a height of 20-30 feet.
Watering Needs
The hawthorn tree has a deep root system, allowing it to absorb water from the soil's lower levels. As such, the plant does not need frequent watering, but the soil should remain consistently moist during the first year of growth. After the first year, the plant can tolerate some drought, but avoid letting the soil dry completely. Water the tree deeply once a week during hot summer months.
Fertilization
Fertilize the hawthorn tree in early spring with a slow-release fertilizer to promote healthy foliage growth. The plant does not need high levels of fertilizer, and excessive application can lead to scorching of leaves. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer according to the manufacturer's instructions and avoid over-fertilization.
Pruning
Prune the hawthorn tree during the dormant season when the plant is not actively growing. Prune to remove damaged or diseased branches and to maintain the plant's shape. The tree benefits from selective pruning, which promotes air circulation and sunlight penetration, reducing the risk of diseases. Avoid heavy pruning as this can affect the plant's growth and produce fewer flowers and fruits.
Propagation of Crataegus calpodendron var. hispida
Crataegus calpodendron var. hispida can be propagated by various methods including seed propagation, cuttings, grafting, and layering.
Seed propagation
Seeds should be collected in the fall and sown immediately in a well-draining medium. After sowing, keep the seeds moist and sheltered from extreme temperatures. Germination can take up to 12 months.
Cuttings
Semi-hardwood cuttings taken in the late summer or early fall are recommended for propagation. Cuttings should be about 6 inches long with several nodes. Dip the base in rooting hormone and plant in a well-draining medium, keeping the soil moist. Rooting can be expected after 6-8 weeks.
Grafting
Grafting is a reliable method for propagating Crataegus calpodendron var. hispida, but requires some expertise. The scions should be collected in late winter and kept in a moist storage until spring. The rootstock should be chosen for its vigor and disease resistance. The scion and rootstock should be joined carefully and securely to ensure a successful union.
Layering
Another effective method for propagation is layering, which involves bending a low-growing branch and burying it in the soil. After a few months, shoots will grow from the buried section. When roots have developed, cut the section from the parent plant and plant in a new location.
Disease Management
The Crataegus calpodendron var. hispida plant is susceptible to various diseases, which can significantly impact its overall health and productivity. Below are some of the most common diseases that can affect this plant and ways to manage them:
Fire Blight
Fire blight is a bacterial disease that affects various plants, including Crataegus calpodendron var. hispida. The disease damages the plant's blossoms, leaves, and shoots, causing them to become blackened and withered. To manage fire blight, remove infected leaves and branches, cutting at least 12 inches below any visible symptoms and destroying them. You may also apply copper-based fungicides or antibiotics to protect your plants.
Cedar Rust
Cedar rust is a fungal disease that affects plants in the rose family, including hawthorn shrubs. It causes rusty brown spots on the leaves and cankers on the stems, which can limit the plant's growth. To manage cedar rust, you can use fungicides or plant resistant cultivars that are less susceptible to the disease. Also, removing and destroying infected parts of the plant may help limit the spread of the disease.
Powdery Mildew
Powdery mildew is a fungal disease that affects various ornamental plants, including Crataegus calpodendron var. hispida. It causes a white or grayish coating on the leaves and shoots, which can be unsightly. To manage powdery mildew, prune the affected branches and leaves and improve air circulation around the plant. Also, use a fungicide specifically developed for powdery mildew management.
Pest management
Crataegus calpodendron var. hispida can be attacked by many pests that can cause significant damage to your plants. Below are some of the most common pests that affect this plant and ways to manage them:
Aphids
Aphids are tiny insects that suck sap from the plant and cause the leaves to curl and deform. They can also transmit viral diseases that can affect the health of your plant. Use insecticidal soap or neem oil to manage the infestation, especially when the pest population is low. When the population is high, you may need to resort to chemical pesticides.
Mites
Mites are arachnids that affect many plants, including Crataegus calpodendron var. hispida. They suck sap from the leaves, causing them to turn yellow and drop. Use insecticides specifically formulated to control mites. You can also use natural insecticides, such as neem oil or insecticidal soap.
Scale Insects
Scale insects are sap-sucking pests that attack various plants, including hawthorn shrubs. They produce a sticky substance that can attract other pests and produce a black sooty mold that can be unsightly. You can manage the infestation by using horticultural oil or insecticidal soap or by removing and discarding affected plant parts.
By paying attention to these treatments and preventing diseases and pests from infesting these plants helps them to be healthy and produce optimally.
