Light Requirements
Crataegus pinnatifida major plant thrives best in full sun to partial shade. It requires at least six hours of direct sunlight every day to grow strong and healthy. Therefore, it's best to place the plant in an area with adequate exposure to sunlight.
Temperature Requirements
Crataegus pinnatifida major plant can tolerate a wide range of temperatures, but it prefers moderate temperatures. The ideal temperature range for the plant is between 60°F and 80°F (15.5°C-26.6°C). It can withstand occasional frost, but it's best to keep it away from extreme cold or heat. Exposure to frost can damage the plant, while high-temperature conditions can have a negative effect on its growth.
Soil Requirements
Crataegus pinnatifida major plant does well in well-draining, fertile soil. The plant prefers slightly acidic to neutral soil pH ranging from 6.0 to 7.5. It can grow in a variety of soil types such as loamy, sandy, and clay soils as long as the soil is well-draining. Poorly drained soils can lead to waterlogging, which can cause root rot and affect the plant's growth and overall health. It's best to add a layer of compost to the soil before planting as it can enrich the soil with nutrients and improve soil drainage.
Cultivation Methods
Crataegus pinnatifida major, commonly known as the Chinese hawthorn, is a deciduous tree that can grow up to 15 feet tall. To cultivate this plant, it requires ample sunlight and well-drained soil. Choose an area with at least six hours of direct sunlight every day and ensure the soil is moist but not water-logged. Plant the tree during the fall or spring and ensure that it has enough space to grow as it matures.
Watering Needs
Regular watering is necessary for the healthy growth of Chinese hawthorn trees. Water the tree once every two weeks, or more frequently during prolonged dry spells. Apply water directly to the soil and avoid wetting the foliage to prevent fungal growth and other diseases. Do not over-water the tree as it can lead to root rot and other waterlogged soil diseases.
Fertilization
Chinese hawthorn trees require regular fertilization to thrive. Apply a balanced slow-release fertilizer once every six months, during the growing season from spring to the end of fall. Use a sufficient amount of fertilizer that is nitrogen, phosphorus, and potassium balanced. Spread it evenly on the soil around the base but avoid contact with the trunk of the tree.
Pruning
Pruning helps to keep the tree in good shape and health, but too much pruning or pruning at the wrong time may damage the tree and reduce harvest yields. Prune the tree during the dormant season to remove damaged or diseased branches. Remove any suckers or water sprouts, any growth below the graft, and any crossing branches that may damage the tree. Light pruning can also be done during the growing season as the tree flowers and fruits to allow more light penetration to the interior of the tree, ultimately enhancing its yield.
Propagation of Crataegus pinnatifida major
Crataegus pinnatifida major, commonly known as the Chinese hawthorn or Shan zha, is a deciduous tree that belongs to the Rosaceae family. This plant is primarily native to China, Japan, and Korea and is known for its small, red, edible fruits that have a sweet-sour flavor. Propagation of Crataegus pinnatifida major can be done by two methods, i.e., seed propagation and grafting.
Seed propagation
One of the essential ways to propagate Crataegus pinnatifida major is seed propagation. The process of seed propagation involves the following steps:
- Collect the ripe fruits from a healthy parent plant.
- Remove the pulp from the fruits and wash the seeds carefully in running water.
- Soak the seeds in water for a couple of days to break their dormancy.
- After two days, remove the seeds from water and dry them on a paper towel.
- Sow the seeds in a seed-starting mix, cover them with a thin layer of soil, and water them thoroughly.
- Place the container in a warm, bright location, and ensure the soil remains moist at all times.
- Germination will occur within 4-6 weeks, so wait until the seedlings are big enough to handle.
- Transplant the seedlings into individual containers and provide them with proper care.
Grafting
Grafting is another effective way to propagate Crataegus pinnatifida major. The process of grafting involves the following steps:
- Select a healthy and robust rootstock of Crataegus pinnatifida major.
- Collect the scion wood of the parent plant during the dormant season.
- Make a clean, smooth cut across the rootstock, about 1-2 inches above the soil level.
- Make a slanting cut on the bottom of the scion wood to match the rootstock cut.
- Join the two cuts and bind them together using grafting tape.
- Cover the grafted site with grafting wax to prevent desiccation.
- Keep the grafted plant in a warm, humid area and check it regularly for any signs of disease or pests.
- Once the graft union is healed, gradually acclimate the plant to normal growing conditions.
Propagation of Crataegus pinnatifida major is relatively easy and can be done by following either seed propagation or grafting methods. However, before propagating, make sure you collect seeds or scion wood from healthy and disease-free parent plants.
Disease and Pest Management for Crataegus pinnatifida major
Crataegus pinnatifida major, commonly known as Chinese hawthorn, is a small tree native to China that produces edible fruits. As with any other plant species, Chinese hawthorn is prone to attack from various pests and diseases that may affect its growth and productivity. It is, therefore, essential to implement proper maintenance and pest management strategies to minimize the incidence of diseases and pests. Below are some of the common diseases and pests that affect Chinese hawthorn and suggestions to manage them.
Common Diseases
Fire blight: This bacterial disease affects multiple plant species, including Chinese hawthorn. Symptoms of fire blight include wilting leaves, blackened branches, and stem cankers. The disease can be managed through pruning of affected branches, application of copper-based fungicides, and good sanitation to reduce the breeding of bacterial agents.
Leaf spot: Leaf spot is a fungal disease that causes small, dark spots on the leaves of the Chinese hawthorn tree. The disease thrives in wet and humid conditions, but proper irrigation, good air circulation, and fungicide application can help prevent its spread.
Cedar apple rust: This disease is caused by a fungus that attacks both Chinese hawthorn and apple trees. It manifests as yellow-orange spots on leaves, eventually causing leaf distortion and premature defoliation. Managing cedar apple rust requires the removal of diseased leaves and debris, good sanitation, and fungicide application.
Common Pests
Aphids: Aphids are small, pear-shaped insects that suck sap from the leaves and stems of Chinese hawthorn. Infestation by aphids can lead to stunted growth, leaf curling, and premature leaf drop. Management involves regular inspection and control measures such as insecticidal soaps and oils.
Spider mites: Spider mites are tiny pests that feed on the sap of Chinese hawthorn, causing discoloration, webbing, and defoliation. They thrive in hot and dry conditions. Management of spider mites involves misting the leaves to increase humidity, removing dust build-up, and insecticide application if necessary.
Codling moth: Codling moth larvae bore into the fruit of Chinese hawthorn, leading to decay and loss of fruit quality. Effective management strategies include monitoring for presence and timely removal of infested fruits, good sanitation, and insecticide application during the flowering and early fruiting stages.
In conclusion, proper management of diseases and pests is crucial to ensure the health and productivity of the Chinese hawthorn plant. Regular monitoring, early detection, and implementation of appropriate control measures will go a long way in preventing and minimizing the impact of diseases and pests.
