Growth Conditions for Crataegus lucorum Sarg.
Crataegus lucorum Sarg. is a shrub belonging to the Rosaceae family that is native to Asia. It is commonly known as the Lebanese hawthorn and is grown for ornamental purposes. In order to ensure proper growth of this plant, the following growth conditions need to be met:
Light Requirements
Crataegus lucorum Sarg. requires full sunlight to grow properly. It can tolerate partial shade, but full sunlight is preferred. Therefore, it is best to plant this shrub in an open area where it can receive direct sunlight for at least six hours per day.
Temperature Requirements
Crataegus lucorum Sarg. prefers a moderate climate. It can tolerate a wide range of temperatures, but it grows best in a temperature range of 10 – 30°C. Extreme cold or hot temperatures can negatively affect its growth. Therefore, it is recommended to grow this plant in regions with a moderate climate.
Soil Requirements
Crataegus lucorum Sarg. can grow in a variety of soils, but it prefers well-drained soil with a slightly acidic to neutral pH. The ideal pH range for this shrub is between 6.0 and 7.0. It does not tolerate waterlogged soil or soil with poor drainage. Therefore, it is important to ensure that the soil is well-drained and healthy before planting.
In summary, Crataegus lucorum Sarg. requires full sunlight, moderate temperatures, and well-drained soil with a slightly acidic to neutral pH for proper growth. By providing these growth conditions, one can ensure that this ornamental shrub grows and thrives as it should.
Cultivation Methods:
Crataegus lucorum Sarg. can be cultivated in areas that have a temperate climate. The plant tends to grow well in areas with an annual rainfall between 600 and 1000mm. It requires well-drained soil that is slightly acidic. The plant is best propagated from seed, and the seeds should be stratified before planting to improve the germination rate. Plant the seeds in pots in the fall and transplant them to the field the following fall when the seedlings are a year old.
Watering Needs:
Crataegus lucorum Sarg. requires consistent watering during the growing season, especially during dry periods. The plant should be watered deeply once a week to encourage deep root growth. It is important not to water the plant excessively as this can lead to root rot. Ensure the soil is moist but not waterlogged.
Fertilization:
A slow-release fertilizer should be applied during the early spring to promote growth. This should be followed up with a second application in early summer to maintain the plant's development. It is essential to apply the appropriate amount of fertilizer as excess amounts can damage the plant.
Pruning:
Pruning should be done during the dormant season to help maintain the plant's shape and remove any diseased or damaged branches. Thin out the center of the plant to improve air circulation and light penetration. Remove any suckers that emerge from the base of the plant as this can cause overcrowding and reduce the plant's growth rate.
Propagation of Crataegus lucorum Sarg.
There are several methods of propagating Crataegus lucorum Sarg., also known as Turkish hawthorn or Omay hawthorn. These include seed propagation, cuttings, and grafting.
Seed propagation
One of the most common ways to propagate Crataegus lucorum Sarg. is through seeds. The seeds are collected in autumn and stratified during the winter months. This is done by placing the seeds in a sealed container with a moist medium in a cool environment, such as a refrigerator, for several weeks. This process helps break the seed dormancy and stimulates germination. After stratification, the seeds are sown in a well-drained, fertile soil mixture and kept moist until germination, which usually occurs within two to three weeks.
Cuttings
Propagation through cuttings is also possible for Crataegus lucorum Sarg. The cuttings are usually taken in summer from current year's growth or in late autumn from hardwood. Semi-hardwood cuttings are the most successful. They are usually 5 – 10 cm long with two to three leaves attached. The base of the cutting is treated with rooting hormone and then inserted into a well-draining rooting medium, such as a mixture of sand, perlite and peat moss. The cuttings are kept in a warm, humid environment and misted regularly until they develop roots.
Grafting
Grafting is a more advanced propagation method that involves taking a stem or bud from the desired plant, known as the scion, and inserting it onto a compatible rootstock. This is commonly done in commercial nurseries to produce plants with desirable traits while maintaining a consistent root system. For Crataegus lucorum Sarg., the best time for grafting is in late winter and early spring when the sap begins to flow. Grafting usually requires expertise and skill, so it may not be an appropriate method for inexperienced gardeners.
Disease and Pest Management for Crataegus lucorum Sarg.
Crataegus lucorum Sarg., commonly known as the Lebanese hawthorn or green hawthorn, is a small tree or shrub that is native to the eastern Mediterranean region. Like all plants, it is susceptible to various diseases and pests that can hamper its growth and development. Here are some common diseases and pests that might affect this plant and ways to manage them:
Common Diseases
Fire Blight: This is a bacterial disease that affects the leaves, flowers, and fruits of the plant, causing them to wilt and turn black. The bacteria spread through rain splashes, insects, and pruning tools. To manage fire blight, pruning the infected parts and disinfecting pruning tools after each cut is essential. Avoid overhead watering and provide adequate spacing between plants.
Leaf Spots: There are several fungal pathogens that cause leaf spots on Crataegus lucorum. Symptoms include small to large, dark or light brown spots on the leaves, leading to defoliation. To manage leaf spots, remove the infected leaves and dispose of them. Avoid wetting the foliage, provide good air circulation, and use fungicides if necessary.
Powdery Mildew: This is a fungal disease that affects the leaves, shoots, and flowers, causing a white, powdery coating on the surface. It can reduce photosynthesis and cause severe defoliation. To manage powdery mildew, prune the infected parts, maintain good air circulation, avoid overhead watering and use fungicides if necessary.
Common Pests
Aphids: These are small, soft-bodied insects that feed on the sap of leaves and stems and excrete honeydew, attracting ants and causing sooty mold. To manage aphids, use a strong stream of water to dislodge them, encourage natural predators, and use insecticidal soap or horticultural oils if necessary.
Scale Insects: These are small, immobile insects that attach themselves on the leaves, shoots, and branches of the plant and suck sap, causing leaves to drop and decreasing the plant's vigor. To manage scales, prune and dispose of the infected parts, use horticultural oils, neem oil, or insecticidal soap applied directly to the scales, and encourage natural predators.
Codling Moth: The larvae of this moth feed on the fruit, causing deep tunnels and rot. To manage codling moth, picking up the fallen fruit, using pheromone traps, and cover the fruits with bags or nets to prevent adult moths from laying eggs inside.
Managing plant diseases and pests is an essential aspect of maintaining healthy and productive plants such as Crataegus lucorum. Regular monitoring, providing favorable conditions, and using appropriate management practices can help reduce the incidence and severity of problems.
