How to Prune American hazelnut?

(Corylus americana)

American hazelnut, also known as American hazel

A deciduous shrub noted for its edible nuts and vibrant fall foliage, american hazelnut benefits from specific pruning methods. To encourage healthy growth and nut production, remove dead or diseased wood, thin out crowded branches, and shape the plant in early spring or late winter. Pruning at this time allows american hazelnut to heal before new growth begins. Regular pruning maintains air circulation and reduces pests, ensuring a robust, productive shrub.

What Are the Benefits of Pruning American Hazelnut?

Pruning american hazelnut encourages strong growth and maintains its desired form. It rejuvenates the plant, ensuring it remains healthy and productive with a visually pleasing structure.

What Is the Best Time for Pruning American Hazelnut?

Spring

Winter

Pruning american hazelnut during late winter or early spring is advantageous as the plant is still dormant, and the absence of foliage allows for a clear view of the structure for making precise cuts. This timing prevents stressing the plant during its active growth phase and ensures energy is directed towards the development of strong, healthy new branches. Additionally, since american hazelnut flowers and sets nuts typically in late spring to early fall, pruning in the recommended seasons avoids removing flower buds, which ensures the plant's ability to produce fruit for the year.

What Tools Do I Need to Prune American Hazelnut?

Hand Pruners

Ideal for making clean cuts on small branches and twigs typically found on american hazelnut. Must be sharp to ensure healthy pruning.

Loppers

Used for branches that are too thick for hand pruners. They give greater leverage to cut through bigger stems safely and efficiently.

Pruning Saw

Essential when dealing with branches over an inch thick that loppers cannot handle, allowing for precision without damaging american hazelnut.

Hedge Shears

Useful for shaping american hazelnut if grown in a hedge form, facilitating even and aesthetically pleasing cuts across multiple stems.

Pole Pruner

Offers extended reach for higher branches without using ladders, maintaining the natural shape and health of american hazelnut.

How to Prune American Hazelnut

Step1: Timing for Pruning

Determine the best time to prune american hazelnut, which is typically in late winter or early spring before new growth begins. This timing helps reduce the risk of disease and allows for better wound healing.

Step2: Tool Selection and Sterilization

Gather the appropriate tools for pruning american hazelnut, such as sharp, clean bypass pruners for smaller branches and loppers or a saw for larger branches. Disinfect tools before use to prevent the spread of disease.

Step3: Removing Dead Wood

Start by removing any dead wood. Identify dead branches by their lack of flexibility and desiccated appearance. Cut these branches at the base where they meet healthy wood, making your cut at a slight angle to promote water runoff and healing.

Step4: Pruning Diseased Limbs

Inspect american hazelnut for any signs of diseased limbs, which may be discolored, have unusual growths, or show signs of decay. Carefully prune away these limbs by cutting them back to a healthy section of the branch, ensuring not to spread the disease to healthy areas.

Step5: Trimming Weak Shoots

Identify weak shoots on american hazelnut that may be too thin, growing at an odd angle, or are overcrowded. Prune these to their point of origin or to a lateral branch that is strong enough to assume the terminal role.

Step6: Shaping and Balancing

After trimming the dead wood, diseased limbs, and weak shoots, step back and examine american hazelnut for shape and balance. Remove any remaining branches that disrupt the symmetry or overall form of the plant, cutting just above a bud or branching point facing the desired direction of growth.

Step7: Thinning for Light and Air

Thin the interior of american hazelnut by removing some of the older branches entirely to improve air circulation and light penetration. This should be done conservatively, ensuring not to remove more than one-third of the total branches in a single season.

Step8: Post-Pruning Cleanup

Clean up all debris from pruning, including leaves, twigs, and branches, to maintain good hygiene around american hazelnut and prevent the spread of any potential diseases found in the pruned material.

Step9: Monitoring for Stress and Disease

Monitor american hazelnut for signs of stress or disease following pruning and address any concerns promptly. Regular aftercare, including proper watering, fertilization, and mulching, can promote healthy regrowth.

Step10: Seasonal Pruning Maintenance

Reevaluate the need for additional pruning throughout the growing season, as american hazelnut may produce suckers or additional weak growth that requires attention.
