Pruning is the selective removal of dead, living or unproductive plant material from trees, shrubs and vines. It is a common practice in home gardening, landscaping and crop production to improve or maintain health, sustain shape, increase yield or quality of flowers or fruits, or protect people, property or structures from falling branches. Pruning can also be used to create specialized forms such as espaliers, topiaries and hedges.
It is important to note that pruning is a natural process that occurs on all plants – even humans – in the form of synaptic pruning. During synaptic pruning, neurons send signals to one another to connect or disconnect synapses. While this may sound like a bad thing, it actually allows for new growth and changes in neural activity to occur. This pruning is not only a natural process, but it also helps maintain brain health and is considered a necessary part of learning and development.
The primary reason for pruning is to remove damaged, diseased or dead limbs. In addition, pruning can encourage new growth, stimulate vigor in existing branches and plants, change undesirable growth patterns, control the size of young trees or shrubs, enhance aesthetics, and promote air flow and sunlight penetration through the canopy. It is especially beneficial to prune trees and shrubs that are planted in the landscape to shape or control size, density and growth habit.
A few common types of pruning cuts include thinning and heading cuts. Thinning cuts remove the ends of branches and stems, while heading cuts reduce or redirect branch length. Both are effective in different situations.
When a pruning cut is made, it should always be back to a bud, a stub (small ring of ridges near the base of a stem where a branch grew from) or the soil line. When leaving stubs, make sure they are no larger than the width of your thumbnail. This will help prevent water sprouts, which can lead to weakened growth and the potential for insect infestation or disease.
The best time to prune flowering shrubs is in the late winter or early spring. This is when they are in dormancy and preparing to produce this year’s blooms. However, many shrubs such as azalea, rhododendron, mountain laurel and forsythia flower on old wood from the previous season, so pruning them later can remove buds that would have produced next year’s flowers.
Crown lifting is a form of pruning to clear the ground for pedestrian or vehicular traffic and space for buildings and street furniture. It involves removing the lower branches of a tree, usually to a predetermined height.
When you prune, be sure to use sharp, clean tools and follow proper technique to ensure the health and longevity of your plants. It is also important to clean your pruning tools between uses and to keep them well-sharpened to prevent damage to the cutting surface. To avoid rust, wipe the cutting surface with 70% alcohol or a 10% bleach solution (1 part bleach to 9 parts water). If you need to sharpen your tool, secure it in a vise or clamp it and use a metal file to remove any nicks or dings.
