How to Prune Laurel sumac?

(Malosma laurina)

Laurel sumac, also known as Laurel sumac

A native shrub notable for its aromatic leaves and red stems, laurel sumac thrives with minimal pruning. Prune in winter to maintain shape, remove dead or damaged wood, and promote healthy growth. Selective thinning out of older stems encourages rejuvenation. Pruning during dormancy minimizes sap loss and disease risk. Regular pruning enhances airflow and reduces the likelihood of pests and diseases, keeping laurel sumac vibrant and full-bodied.

What Are the Benefits of Pruning Laurel Sumac?

Pruning laurel sumac encourages vigorous growth and helps maintain a neat plant shape. Regular cutting back removes old wood, promoting new shoots for a fuller, healthier appearance.

What Is the Best Time for Pruning Laurel Sumac?

Winter

Pruning laurel sumac in late winter to early spring allows for the removal of any damaged or diseased branches before the plant invests energy in new foliage. This timing aligns with laurel sumac's dormancy period, minimizing stress and sap loss. It also helps maintain the plant's shape and encourages vigorous growth in the spring, while avoiding disrupting the natural flowering cycle that occurs in the summer. Pruning during this period also provides the opportunity for the gardener to assess the plant's structure without the obstruction of leaves.

What Tools Do I Need to Prune Laurel Sumac?

Hand Pruners

Due to the moderate thickness of laurel sumac's branches, hand pruners are ideal for making clean cuts on smaller stems and branches, which promotes healthy regrowth. Look for bypass pruners, which make precise cuts and are less likely to cause damage to the plant tissue.

Lopping Shears

Laurel sumac can have thicker branches that may require a tool with more leverage. Lopping shears can cut through branches that are too thick for hand pruners, usually up to 1 and 1/2 inches in diameter. Their long handles provide the necessary leverage.

Pruning Saw

For mature laurel sumac with thicker branches exceeding the capacity of lopping shears, a pruning saw is necessary. It is designed to cut through thick branches and limbs cleanly, minimizing damage and ensuring a healthy recovery for the plant.

Hedge Shears

If shaping is required for laurel sumac, particularly for creating a formal appearance, hedge shears are suitable. They allow for the trimming of multiple small branches at once and help maintain a neat, structured look.

How to Prune Laurel Sumac

Sanitize tools

Before pruning laurel sumac, clean and sanitize all cutting tools to prevent the spread of disease. Use a solution of one part bleach to nine parts water or a disinfectant recommended for gardening tools.

Identify parts

Inspect laurel sumac thoroughly to identify dead or diseased branches. Look for branches that are discolored, have unusual growths, or are clearly dead and brittle.

Make cuts

Using sharp, sanitized pruning shears, make clean cuts to remove dead or diseased branches. Cut at a 45-degree angle, about a quarter inch above a live bud or branch junction, ensuring not to damage healthy tissue.

Disposal

Dispose of the removed dead or diseased branches immediately, away from healthy laurel sumac plants or compost to prevent the potential spread of disease.

Clean up

After pruning, clean the area around laurel sumac to remove any fallen debris. Clean and sanitize your tools once again to prevent carrying diseases to other plants.

Common Pruning Mistakes with Laurel Sumac

Overzealous pruning

Cutting too much at once can stress laurel sumac, leading to poor growth or increased susceptibility to disease. It's crucial not to remove more than 20-30% of the growth in a single pruning session.

Improper cut locations

Incorrect cutting sites can result in damage to laurel sumac. Cuts should be made at a slight angle, just above outward-facing buds or branching points, to promote healthy regrowth.

Use of dull tools

Dull pruning tools can cause jagged cuts that are more prone to infection. Sharp, clean tools create smooth cuts that heal faster.

Neglecting sanitation

Failing to sanitize tools between uses on different plants can spread disease to laurel sumac. Clean cuts reduce the risk of transmitting pathogens.

Pruning healthy tissue

Unnecessarily cutting healthy branches can harm laurel sumac's natural shape and growth patterns. Focus on removing only dead, diseased, or overgrown branches.

Common Pruning Tips for Laurel Sumac

Selective pruning

Aim to selectively thin out crowded areas and remove any dead or diseased branches to maintain good air circulation and sunlight penetration, which are essential for laurel sumac's health.

Shape maintenance

Encourage laurel sumac's natural growth habit by pruning to maintain its round, mounding shape. This approach respects the plant's innate form and promotes a pleasing appearance.

Gradual rejuvenation

If laurel sumac requires rejuvenative pruning, perform this gradually over a few seasons to reduce stress on the plant. Stagger intensive pruning work to allow the plant time to recover.

Cutting technique

When removing larger branches, use the three-cut method to prevent bark tearing: make a notch on the underside of the branch away from the trunk, then cut down from the top above the notch, and finally cut the stub close to the trunk.

Post-pruning care

After pruning laurel sumac, ensure it receives proper care, such as adequate watering and mulching, to support recovery and new growth.
