Pruning Tips

Pruning is the selective removal of branches and limbs from plants, shrubs, trees, or vines to improve their shape, health, appearance, or utility. It is a common practice in orchards and vineyards to promote fruit production and is a critical aspect of landscape maintenance. The pruning of flowers and ornamental plants enhances their appearance, allowing them to bloom or produce fruit in greater numbers than they would without regular trimming.

Removing damaged or diseased limbs allows the plant to concentrate its energy on healthy growth and reduces the risk of damage, decay, or insect infestation. Thinning dense areas of the canopy increases air circulation and reduces the risk of fungal diseases. Pruning can also increase light penetration to the ground, which improves visibility and lowers the risk of property damage or injury.

Trees and shrubs need to be pruned regularly to achieve their full potential. Pruning is essential for a healthy, beautiful landscape and is one of the best investments you can make to improve your outdoor space.

When pruning your shrubs, always make the best possible cuts. This ensures the health of the plant and maintains its structural integrity, extending its life and beauty.

Different pruning goals require different types of cuts and techniques. For example, crown reduction involves removing entire branches or reducing their length to reduce the overall size of the canopy. This helps to reduce glare from overhead lighting or to provide better views through the foliage. Crown lifting, on the other hand, removes a limited amount of lower branches to allow pedestrian and vehicle access below. It is a common procedure for street and urban gardens as it improves safety and makes way for sidewalks, streets, buildings, and other structures.

Aim for a balanced crown with an even canopy shape. This method involves removing small limbs that are growing low or into the canopy and may involve thinning a densely packed area of a branch. It is important to consider a species’ normal form and the landscape it will be planted in when planning this type of pruning operation.

Plants that bloom on old wood should be pruned no later than early spring after they have finished blooming. This gives the plant time to grow buds for next year’s flowers. This includes azaleas, lilacs, gardenias, rhododendrons, magnolias, forsythias, mountain laurel, and flowering plums. It is best to consult the pruning lists for these plants for specific pruning instructions. Similarly, fruit trees that bloom on new wood should be pruned within 30 to 45 days after they have finished producing. Pruning later than this can significantly decrease the yield for the current season.
