Tips for Protecting Your Plants from Cherry Nose Cicadas

Cherry Nose Cicadas, known for their distinctive appearance and loud buzzing sounds, can be a significant nuisance to gardeners and plant enthusiasts. While cicadas play an essential role in the ecosystem, their feeding habits can cause damage to various plants, particularly young trees and shrubs. Protecting your plants from these insects requires a combination of preventative measures, monitoring, and timely interventions. In this article, we will explore effective strategies and tips for safeguarding your garden from the potential harm caused by cherry nose cicadas.

Understanding Cherry Nose Cicadas

Before diving into protection methods, it’s crucial to understand what cherry nose cicadas are and why they can be problematic for your plants.

What Are Cherry Nose Cicadas?

Cherry nose cicadas are a type of cicada species characterized by a small red or cherry-colored mark near their noses or heads. They belong to the larger family of cicadas, which are known for their distinctive sound production through specialized membranes called tymbals.

Lifecycle and Behavior

Cicadas spend most of their lives underground as nymphs feeding on root sap. After several years (sometimes up to 17 years depending on species), they emerge en masse to mate, lay eggs, and die shortly after. This emergence phase is when they become visible pests.

Female cicadas lay eggs by cutting small slits into plant stems or branches with their ovipositors. This egg-laying can cause damage known as “flagging,” where branches wilt or prematurely die. The feeding by nymphs and egg-laying can stress plants, especially young or vulnerable ones.

Symptoms of Cicada Damage on Plants

Recognizing signs of cicada damage early helps you take prompt action. Here are some symptoms:

• Flagging Branches: Small twigs or branches suddenly wilt and die.
• Scarring on Stems: Visible cuts or scars where females have laid eggs.
• Reduced Growth: Overall stunted growth due to stress.
• Leaf Damage: Although less common, leaves may have minor bite marks.
• Premature Leaf Drop: Trees may shed leaves earlier than usual.

Tips for Protecting Your Plants from Cherry Nose Cicadas

1. Use Physical Barriers

One of the most effective ways to protect your plants is by using physical barriers that prevent the adult cicadas from reaching the stems and branches where they lay eggs.

• Fine Mesh Netting: Covering young trees and shrubs with fine mesh netting during peak cicada season can block females from accessing the branches.
• Screening with Garden Fabric: Lightweight garden fabric can be draped over smaller plants.

Make sure nets are securely fastened so cicadas cannot slip underneath. Remove barriers after emergence season to allow pollination and airflow.

2. Timing Planting to Avoid Peak Emergence

If you live in an area with predictable cicada emergence cycles (such as periodical cicadas), plan planting schedules accordingly:

• Avoid planting new trees or shrubs just before an expected cicada emergence year.
• Focus on planting after the emergence has passed to reduce vulnerability.

This strategy helps young plants establish without the additional stress caused by cicada damage.

3. Prune and Remove Damaged Branches

Regular inspection during and after emergence season is essential:

• Prune out flagged or damaged branches promptly.
• Discard pruned material away from your garden area to reduce the risk of attracting more cicadas.

Pruning helps prevent secondary infections that can occur on damaged plant tissue.

4. Maintain Plant Health Through Good Cultural Practices

Healthy plants withstand pest stress better than weak ones:

• Watering: Provide consistent watering during dry spells.
• Mulching: Apply mulch around trees to retain moisture and regulate soil temperature.
• Fertilizing: Use balanced fertilizers to promote robust growth but avoid over-fertilizing which may attract pests.

Strong plants can recover faster from cicada damage.

5. Encourage Natural Predators

Nature provides a range of predators that feed on cicadas including birds, spiders, praying mantises, and some predatory insects.

• Create habitat that attracts these predators such as birdhouses or insect hotels.
• Avoid broad-spectrum insecticides that kill beneficial insects along with pests.

By fostering a balanced ecosystem, you reduce cicada populations naturally.

6. Use Organic Insecticides Carefully

While chemical control is generally not recommended due to limited effectiveness against adult cicadas and potential harm to non-target species, some organic options may help if populations are very high:

• Neem oil sprays applied early in the season can deter egg-laying females.
• Insecticidal soaps may help control nymphs when they emerge from the soil.

Always follow label instructions and apply treatments during cooler parts of the day for best results.

7. Create Barriers on Tree Trunks

Applying sticky bands around tree trunks can trap nymphs as they climb up from underground after emerging:

• Wrap tree trunks with a barrier wrap.
• Smear a band of sticky compound (available commercially) around the wrap.

Check bands regularly and replace as needed during emergence periods.

8. Consider Resistant Plant Varieties

Some tree species show greater resistance or tolerance to cicada damage:

• Research native or adapted varieties less prone to egg-laying damage.
• Consult local extension services for recommendations tailored to your region.

Using resistant varieties reduces maintenance and plant loss risk.

Monitoring Cicada Activity

Proactive monitoring is key:

• Watch for early sightings of adult cicadas in late spring or early summer depending on your location.
• Use pheromone traps or visual inspections to gauge population sizes.

Early detection allows you to deploy protective measures promptly before serious damage occurs.

Summary: Integrated Approach Works Best

Protecting your plants from cherry nose cicadas demands an integrated pest management (IPM) approach combining multiple strategies:

• Physical barriers block access effectively during brief emergence windows.
• Timing planting schedules reduces exposure risk.
• Regular pruning removes damaged material limiting infection risk.
• Maintaining vigorous plant health minimizes long-term impacts.
• Encouraging natural predators keeps pest populations balanced.
• Selective use of organic treatments may help in severe cases.

By understanding cherry nose cicada biology and following these tips, gardeners can enjoy healthy plants with minimal disruption from these fascinating yet troublesome insects.

Invest time in observation and preparation so each cicada season passes smoothly with minimal damage—your garden will thank you!
