- Regularly prune the plant for shape and size, focusing on removing dead or damaged stems and branches.
- Prune the plant in the dormant season or after the blooming season to maintain its shape and size.
- Remove any water sprouts, thin the canopy, and remove crossing or rubbing branches as needed.
- Only prune up to 25% of the Crataegus Harveyana Sarg. in a year to avoid damaging new growth and affecting the overall health of the plant.
Propagation of Crataegus harveyana Sarg.
Crataegus harveyana Sarg. can be propagated through various methods such as seeds, cuttings, and grafting.
Propagation by Seeds
Seeds of Crataegus harveyana Sarg. should be collected from mature fruits during fall. The seeds should be cleaned and stratified at 4°C to 5°C for at least 120 days. Stratification helps to break the seed dormancy, and enables germination to occur. After stratification, the seeds should be sown in a well-drained propagation medium in spring.
Propagation by Cuttings
Hardwood stem cuttings of Crataegus harveyana Sarg. should be taken in winter when the plant is dormant. The cuttings should be approximately 20 cm long, with at least 2 to 3 nodes. The basal end of the cutting should be treated with a rooting hormone and placed in a rooting medium. The cuttings should be kept in a cool and humid environment until they develop roots in 2 to 3 months.
Propagation by Grafting
Grafting is a reliable method for propagating Crataegus harveyana Sarg. The rootstock should be a closely related species of Crataegus that matches the scion in terms of growth habit and vigor. The graft union should be made using the cleft grafting method in late winter or early spring. After grafting, the plant should be kept in a greenhouse until it establishes successfully.
Disease Management:
Crataegus harveyana Sarg. is generally a hardy plant that is not prone to many diseases. However, it can become susceptible to diseases under certain conditions or if it is not properly cared for.
One common disease that can affect this plant is fire blight, which is a bacterial disease that can cause the leaves and branches to turn black and die. To manage fire blight, remove any infected plant material immediately and destroy it to prevent further spread. Prune the plant regularly to increase ventilation and reduce humidity. Additionally, avoid overhead watering and do not fertilize excessively as these practices can contribute to the growth of the bacteria that causes fire blight.
Another potential disease is leaf spot, which is a fungal disease that can cause yellow or brown spots on the leaves. To manage leaf spot, remove any infected plant material and destroy it. Avoid overhead watering and provide adequate air circulation to prevent the growth and spread of fungal spores. Fungicides can also be used as a preventative measure to manage leaf spot.
Pest Management:
Crataegus harveyana Sarg. can be susceptible to a few pests, including scale insects and aphids.
Scale insects can cause yellowing of leaves, stunted growth, and leaf drop. To manage scale insects, prune any affected areas of the plant and dispose of them properly. Additionally, you can use insecticides specifically targeted to scale insects, or you can opt for non-toxic methods such as spraying the plant with a solution of water and dish soap.
Aphids can cause distorted growth, wilting, and yellowing of leaves. To manage aphids, you can spray the plant with a strong stream of water to dislodge the pests. Additionally, you can introduce natural predators such as ladybugs or lacewings or use insecticides specifically targeted to aphids.
