Cherry trees are a popular choice for gardeners and orchardists alike, offering beautiful blossoms in the spring and sweet, tart fruit in the summer. Whether you're growing sweet cherries for fresh eating or tart cherries for baking and preserves, taking care of your cherry tree properly is essential to ensuring healthy growth and a bountiful harvest. However, cherry trees can be sensitive to various challenges, from pests and diseases to environmental stress. In this blog post, we'll discuss how to address the most common issues that may arise while caring for your cherry tree and provide tips for successful cherry tree care.

1. Choosing the Right Cherry Tree Variety

Before you dive into caring for your cherry tree, it's important to choose the right variety for your climate and needs. There are two main types of cherry trees: sweet cherries (Prunus avium) and tart cherries (Prunus cerasus), and each has different growing requirements.

Climate and Growing Zone

  • Sweet Cherries: These varieties thrive in warmer climates with mild winters, making them ideal for USDA hardiness zones 5-7. They require a long growing season and are more susceptible to frost damage during bloom time.

  • Tart Cherries: Tart cherries are more cold-hardy and can withstand colder winters. They're better suited for USDA zones 4-6 and generally have a shorter growing season than sweet cherries.

Pollination

Many cherry tree varieties require cross-pollination for fruit production, so it's important to plant at least two compatible varieties that bloom around the same time. Some self-pollinating varieties are available, but cross-pollination generally yields better results.

2. Planting and Site Selection

Planting your cherry tree in the right location and using proper techniques will set the foundation for healthy growth.

Location

  • Sunlight: Cherry trees need at least 6-8 hours of full sunlight each day. Choose a location with good sunlight exposure, as it’s crucial for the development of strong fruit and healthy foliage.

  • Soil: Cherry trees prefer well-draining, slightly acidic soil (pH 6.0-7.0). Avoid heavy clay soil, as poor drainage can lead to root rot.

  • Space: Ensure there is enough space between trees (about 20 feet for standard trees) to allow for proper airflow and prevent the spread of diseases.

How to Plant a Cherry Tree

  1. Dig a Hole: The hole should be at least twice as wide as the root ball and just as deep. Loosen the soil around the hole for better root penetration.

  2. Plant the Tree: Place the tree in the hole, making sure the root collar is level with the surrounding soil. Fill the hole with soil, and tamp it gently to remove air pockets.

  3. Water: Water the tree thoroughly after planting and mulch around the base to retain moisture and suppress weeds.

3. Watering Cherry Trees

Watering cherry trees correctly is vital to their overall health and fruit production. Both under-watering and over-watering can stress the tree and lead to poor growth.

Watering Guidelines

  • Young Trees: Newly planted cherry trees need regular watering to establish their roots. Water deeply once a week, especially during dry periods. Ensure the water reaches the root zone, where the tree’s roots are actively growing.

  • Established Trees: Older trees require less frequent watering but should still receive deep watering during prolonged dry spells. Water deeply around the tree’s drip line (the area under the tree's outermost branches) to encourage deep root growth.

  • Avoid Over-Watering: Cherry trees are particularly susceptible to root rot, so ensure the soil has good drainage and avoid waterlogging.

4. Pruning Cherry Trees

Pruning is an essential part of maintaining your cherry tree’s shape, improving air circulation, and ensuring healthy fruit production.

When to Prune

  • Winter Dormancy: The best time to prune cherry trees is during the late winter or early spring when the tree is dormant. This minimizes the risk of disease and encourages healthy growth once the growing season begins.

  • Summer Pruning: You can also prune in the summer to remove dead, damaged, or diseased wood and to manage the tree's size.

Pruning Tips

  • Remove Dead or Diseased Wood: Start by cutting away any dead, broken, or diseased branches to improve air circulation and prevent fungal infections.

  • Shape the Tree: Aim for an open-center structure to allow light and air to reach the interior branches. This will help with fruit development and reduce the risk of fungal diseases.

  • Thinning: If the tree has too many branches or is overcrowded, thin out some of the weaker, less productive branches to encourage stronger growth and better fruiting.

5. Common Cherry Tree Diseases and How to Prevent Them

Cherry trees are susceptible to several diseases, most of which can be managed with good cultural practices and proper care.

1. Cherry Leaf Spot

  • Symptoms: Brown or black spots on leaves, followed by yellowing and premature leaf drop.

  • Prevention: Practice proper spacing to improve airflow around the tree. Remove fallen leaves in the fall, and apply a fungicide during the growing season if needed.

2. Brown Rot

  • Symptoms: Soft, mushy fruit that becomes brown and decayed, often affecting cherries at harvest time.

  • Prevention: Remove infected fruit and twigs, and avoid overhead watering, which can promote fungal growth. Use fungicides as a preventive measure during rainy periods.

3. Powdery Mildew

  • Symptoms: A white, powdery coating on leaves, stems, and fruit.

  • Prevention: Prune to increase airflow, and apply a fungicide at the first sign of mildew.

4. Canker Diseases

  • Symptoms: Sunken, discolored lesions on branches and trunks, often leading to dieback.

  • Prevention: Prune affected branches and remove any infected wood. Avoid wounding the tree, as open cuts are more susceptible to infection.

6. Pest Control for Cherry Trees

Cherry trees are also prone to various pests, which can damage the tree and reduce fruit quality.

Common Cherry Tree Pests

  • Cherry Fruit Fly: These flies lay eggs on the fruit, causing it to rot. Use traps to catch adult flies and remove any infected fruit.

  • Aphids: Aphids suck sap from the leaves, leading to curled, discolored leaves. Control aphids by using insecticidal soap or introducing natural predators like ladybugs.

  • Japanese Beetles: These beetles feed on the foliage, leaving behind skeletonized leaves. Handpick them off the tree or use organic insecticides to manage infestations.

  • Spider Mites: Tiny, red pests that feed on the undersides of leaves, causing them to turn yellow and curl. Apply insecticidal soap or introduce predatory mites to control populations.

7. Protecting Cherry Trees from Weather Stress

Cherry trees can be sensitive to extreme weather conditions, such as late spring frosts, high winds, or drought.

Frost Protection

Cherry trees bloom early in the spring, which makes them vulnerable to late-season frosts. If frost is forecasted after the tree has bloomed, consider covering the tree with a frost cloth or using a temporary shelter to protect the blossoms.

Wind Protection

Strong winds can damage branches and cause fruit to drop prematurely. Plant cherry trees in a sheltered location, such as near a fence or windbreak, or use stakes to provide additional support.

Drought Protection

During periods of drought, ensure your cherry tree is watered deeply. Adding mulch around the base of the tree helps retain moisture and regulates soil temperature.

8. Harvesting Cherries

The best part of caring for a cherry tree is harvesting the fruit. Here’s how to tell when your cherries are ready:

  • When to Harvest: Cherries typically ripen in early to mid-summer, depending on the variety. Sweet cherries should be fully ripe when they’re sweet to the taste, while tart cherries should be firm but slightly sour.

  • How to Harvest: Gently pull cherries from the tree, being careful not to damage the fruit or the tree. Use a gentle twisting motion to avoid tearing the stems.

Conclusion

Cherry trees can be a joy to grow, but they do require attention to ensure they thrive and produce high-quality fruit. By addressing common challenges such as pests, diseases, pruning, and proper watering, you’ll be well on your way to enjoying a successful cherry harvest. Whether you're growing cherries for fresh eating, pies, or preserves, following these care tips will help you get the most out of your cherry tree.
