Light requirements
Crataegus caesa, commonly known as the thornless cockspur hawthorn, grows well in full sun to partial shade. It requires at least 6 hours of direct sunlight every day to flower and fruit properly. Too much shade can result in leggy growth and reduced fruit production.
Temperature requirements
This plant can grow in a wide range of temperatures from -20°C to 40°C. However, it thrives in temperatures between 18°C and 20°C. The plant requires a cold dormancy period in winter to break bud dormancy, so it can grow properly during the summer months. Therefore, a temperature of around 5°C is necessary during the winter months.
Soil requirements
The hawthorn plant grows well in well-drained soils that are slightly acidic to neutral. It does not grow well in soils that are waterlogged or have poor drainage. Ideally, the soil should have a pH between 5.5 and 7.5. The plant is quite tolerant of saline soils and can grow in soils with a high salt content. It is a drought-tolerant plant, meaning it can grow in soils that do not hold water for long periods.
Cultivation of Crataegus caesa
Crataegus caesa, commonly known as the black hawthorn or Douglas hawthorn, is best cultivated in well-drained soils with a pH ranging from 6.5 to 7.5. It thrives in full sunlight and prefers sheltered locations, as the wind can damage branches and leaves.
Watering Needs of Crataegus caesa
Black hawthorn plants require moderate watering during their growing season, usually in the spring and summer months. Ensure the soil is moist, but not soaking wet. Never let the soil dry out, as this may damage the plant's roots. Watering should be minimized during winter months as the plant goes dormant and requires less water.
Fertilization of Crataegus caesa
Regular fertilization is recommended for the optimal growth of black hawthorn plants. A balanced fertilizer can be applied in early spring and mid-summer. Nitrogen-rich fertilizers can cause excessive growth, which weakens the plant, so it is best to use a fertilizer that equally provides Nitrogen, Phosphorus, and Potassium (NPK). Follow the instructions on the packaging and avoid over-fertilizing, as it can cause fertilizer burn that can lead to the death of the plant.
Pruning Crataegus caesa
Pruning black hawthorn plants is essential to maintain their shape and promote healthy growth. Pruning should be done in late winter or early spring while the plant is still dormant. Use sharp, clean tools and cut back any dead or diseased branches, making sure to cut at a 45-degree angle. Thin out any overcrowded areas and remove any crossing branches. If the plant is overgrown, it can be trimmed back by up to one third of its size to encourage new growth.
Propagation of Crataegus caesa
Crataegus caesa, commonly known as scarlet hawthorn or red hawthorn, is a deciduous tree or shrub native to the eastern and central United States. It is widely used in landscaping and is also known for its medicinal properties. The plant can be propagated through various methods, which are discussed below:
Seeds
Seeds are the most common and easiest method of propagation for Crataegus caesa. The best time to collect seeds is in the fall when they have ripened and fallen to the ground. The seeds should then be cleaned and stored in a cool, dry place until spring. In the spring, the seeds can be sowed directly into the ground or in a nursery bed.
Cuttings
Cuttings are a popular method of propagation for many plants and can also be used for Crataegus caesa. The best time to take cuttings is in the late spring or early summer when the plant is actively growing. Semi-hardwood cuttings of around 6 inches in length should be taken and inserted into a potting mix of equal parts peat moss and vermiculite. Keep the cuttings moist and in a shaded area until roots have developed, and then they can be transplanted to a permanent location.
Grafting
Grafting is a method of propagation that involves fusing the bark of two different plants together to create a new plant. This method is commonly used for fruit trees and can be used for Crataegus caesa as well. The best time for grafting is in late winter or early spring when the plant is dormant. Care should be taken to ensure that the graft union is secure and that the plant is kept moist until the graft has taken.
Air Layering
Air layering is a method of propagation that involves creating a small wound on a stem or branch of the plant, applying rooting hormone, and then wrapping the area with moist sphagnum moss or another rooting medium. Once roots have developed, the section can be cut from the plant and transplanted. This method is typically used for larger plants.
Overall, Crataegus caesa can be propagated through a variety of methods, allowing for easy propagation and cultivation of this popular plant.
Diseases and Pests Affecting Crataegus caesa
Crataegus caesa, commonly known as "dotted hawthorn," is a deciduous shrub that is relatively resistant to pests and diseases. However, there are a few diseases and pests that can affect this plant if proper management strategies are not put in place.
Common Diseases
The most common diseases affecting Crataegus caesa are anthracnose, rust, and fire blight. Anthracnose is a fungal disease that causes discoloration, defoliation, and twig blight. Rust is a fungal disease that can cause defoliation and deformation of leaves. It is characterized by the appearance of orange spores on affected leaves. Fire blight is a bacterial disease that causes wilting, scorching, and blackening of leaves and stems.
To manage these diseases, it is essential to keep the plant healthy and vigorous by providing adequate water and nutrients. Also, avoid overhead watering, as this can promote the growth and spread of fungal diseases. It is also recommended to remove infected plant parts and destroy them to prevent the spread of the disease. In severe cases of fire blight, pruning may be necessary to eradicate the disease completely.
Common Pests
The main pests affecting Crataegus caesa are spider mites and aphids. Spider mites are tiny pests that can suck the sap from leaves, causing them to turn yellow or brown. They can also spin webbing, which can accumulate on leaves, causing them to become sticky. On the other hand, aphids are small insects that can cause curling and yellowing of leaves, as well as stunted growth.
To manage spider mites and aphids, it is essential to regularly inspect the plant for signs of infestation. One way of controlling these pests is by using a strong stream of water to dislodge them from the leaves. Alternatively, you can use insecticidal soap or neem oil to kill and repel the pests. It is important to note that using chemical pesticides should be considered as a last resort, as they can harm beneficial insects and pollinators.
In summary, proper management of pests and diseases affecting Crataegus caesa involves regular inspection of the plant, maintaining plant health, and applying appropriate control measures as necessary.
