Kwanzan Cherry Tree Planting Tips
You can plant Kwanzan cherry trees as stunning specimen trees in rows, along buffer strips and driveways, or even as a bonsai in a container. When planting your tree, choose a location with well-draining soil and full sunlight. If you plant several, space them 12–15 feet apart from the center of the trunk.
Kwanzan cherry trees’ roots have a difficult time competing with grass, so plant them in a raised mound bed, especially if you’re worried about poor drainage. The mound should be 12–18 inches above the surrounding soil. If your climate is hot, spread a layer of mulch that is 3–4 inches deep.
Make sure it’s moist after planting by poking your finger into the soil and checking the moisture. If it feels moist, you don’t need to water. If it feels dry, water deeply.
Kwanzan Cherry Tree Growing Conditions
Kwanzan cherry trees are relatively low-maintenance and can grow in a range of sunlight hours and soil. However, they are short-lived due to their susceptibility to pests and disease.
- Sun and shade: Kwanzan cherry trees thrive in full sunlight, with at least six hours of direct, unfiltered sunlight per day. However, they can also tolerate partial shade.
- Soil: The key aspects of soil for these cherry trees are well-draining and moist. Other than that, Kwanzan cherry trees aren’t too picky. They will do well in loamy, sand, or clay soils, and can tolerate both acid and alkaline pH levels.
- Watering: Water your Kwanzan cherry tree deeply but irregularly, one to two times per week. If the top 2 inches of soil are dry, it’s time to water.
- Fertilizing: You won’t need to fertilize your Kwanzan cherry tree for the first year or two, but after that, fertilize with a slow-release, nitrogen-rich blend in the spring to boost growth.
- Pruning: Kwanzan cherry trees do not require pruning unless you see diseased or dying limbs, which should be cut immediately. However, you can prune trees to shape and cut off any limbs that have grown too heavy for its base. Only prune after the tree has flowered for the season.
- Pests and diseases: Troublesome pests that target Kwanzan cherry trees include aphids, caterpillars, borers, scale, spider mites, and Japanese beetles. Common diseases include powdery mildew, root rot, leaf curl, and fireblight.
Potential Kwanzan Cherry Tree Problems and Solutions
As with any type of tree, Kwanzan cherry trees can experience fungal diseases, pest damage, and other issues over time. Learn more about common problems you can experience with Kwanzan cherry trees and recommended solutions.
- Fungal diseases: Fungal diseases such as cherry leaf spot and powdery mildew can cause premature leaf drop and weaken the tree. To fix this, improve air circulation with light pruning and avoid overcrowding. Apply fungicide in early spring if infections are frequent.
- Root rot: This issue is often caused by poor drainage or overwatering. Ensure the tree is planted in well-draining soil and water only as needed to prevent soggy roots.
- Pests: Insects such as aphids, scale insects, and Japanese beetles feed on leaves or sap, potentially stunting tree growth. Use insecticidal soap or neem oil to control infestations and attract natural predators like ladybugs to your garden.
- Bark splitting or cracking: This can occur from rapid temperature changes or mechanical injury. Protect young trees with tree wraps during harsh winters and avoid damaging the trunk with lawn equipment.
- Nutrient deficiencies: Yellowing leaves or poor growth can signal a lack of nutrients. Conduct a soil test and amend with a balanced fertilizer as needed, especially in the early spring.
Our Conclusion
Japanese flowering cherry trees show off pink blooms and vibrant leaves every season. With a short lifespan of 15–20 years, they thrive in direct sunlight but do well in partial shade gardens too.
