There’s no getting away from it, pruning is a crucial gardening task that helps maintain plant health, shape, and flowering potential in your outdoor space! For certain plants, June is the perfect time to call in your tree trimming service to prune as it sets your trees up for optimal growth and recovery before the next season. 

Plants That Need Tree Trimming In June

  • Serviceberry

Serviceberries are versatile, attractive shrubs or small trees known for their stunning spring flowers and edible berries. Pruning serviceberries in June, after they have finished flowering and fruiting, encourages better airflow and reduces the risk of disease. Focus on removing dead, damaged, or crossing branches to improve the plant’s structure.

  • Viburnum

Viburnums are popular ornamental shrubs valued for their fragrant flowers and attractive foliage. June is an ideal time to prune viburnums as they have finished blooming by this time. Remove spent flowers, thin out crowded branches, and cut back any dead or diseased wood. This helps maintain the plant’s shape and encourages robust growth for the following season.

  • Clematis Montana

Clematis Montana is a vigorous, early flowering climber that benefits from pruning after its spring bloom. In June, prune to remove dead or weak stems, and cut back flowered stems to a pair of healthy buds. This keeps the plant in check, preventing it from becoming overly dense and promoting a flush of new growth that will produce next year’s flowers.

  • Weigela

Weigela, known for its trumpet shaped flowers, should be pruned in June after its spring bloom. Pruning at this time encourages a second, lighter bloom in late summer and maintains the shrub’s shape. Remove any dead or old wood, thin out crowded areas, and cut back shoots that have finished flowering to a strong bud or side shoot.

  • Lilacs

Lilacs are beloved for their fragrant spring blooms. Pruning lilacs in June, right after they finish flowering, helps promote more vigorous growth and better blooms for the next year. Remove spent flower heads, thin out old or weak stems, and cut back to healthy shoots. This encourages the development of new growth and prevents the plant from becoming too leggy.

  • Magnolias

Magnolias should be pruned carefully to avoid damaging their natural shape. For deciduous magnolias, June is an excellent time to prune after flowering. Remove dead, diseased, or crossing branches, and make sure to cut back any suckers or water sprouts. Avoid heavy pruning as magnolias do not respond well to drastic cuts.

  • Berberis

Berberis, known for its colorful foliage and small, attractive flowers, should be pruned in June to maintain its shape and encourage new growth. Remove any dead or damaged branches, and thin out the plant to improve air circulation. Berberis can be pruned quite heavily if needed but ensure that you maintain the desired shape and size for your garden space.
