The best time to prune trees is when they’re dormant. That’s typically in late fall, winter, or early spring (before new growth begins). These times are ideal for pruning because trees are resting. This minimizes tree stress and sets the stage for vigorous growth during the season.

Pruning mature shade trees is straightforward. If you have fruit trees, however, pruning goals and techniques differ from those for mature shade trees. Pruning fruit trees isn’t just about keeping them healthy; it’s a powerful management tool ensuring a consistent, high-quality, easy-to-harvest crop.

Prune During Dormant Seasons

Pruning fruit trees, especially during the dormant season, is a critical yearly practice with three crucial objectives:

• Maximize fruit production and quality
• Improve light and air flow
• Maintain structural integrity and the tree’s lifespan.
Pruning removes excess flower buds and branches that could produce fruit. By reducing the amount of fruit the tree produces, the remaining fruit can access more of the tree’s stored energy and nutrients, resulting in larger, better-tasting, and more uniform fruit.

Pome Fruit Pruning versus Stone Fruit Pruning
Pome fruit trees (apples, pears) produce fruit on spurs—short, permanent structures on wood two years or older. Pruning focuses on training a central leader to encourage sunlight penetration and preserve these long-lived spurs.
Stone fruit trees (peaches, plums) produce fruit on mostly one-year-old wood. Pruning must stimulate vigorous new growth annually and maintain an open vase shape. This approach delivers maximum sun into the tree’s center and all new branches.
Essential Fruit Tree Pruning Tips
Here are six essential hacks for pruning your fruit trees in winter:

  1. Master the timing: late winter is best
    Prune when the tree is fully dormant, after all the leaves have fallen but before the buds start to swell. This task is typically performed in winter, from December to March, in most temperate regions. Pruning cuts made too early in winter can be vulnerable to frost damage.
    Cutting closer to spring allows the wound to heal almost immediately when the tree breaks dormancy, reducing the chance of disease. Always prune on sunny, dry days. Moisture can help spread disease pathogens into the fresh cuts.
  2. Start with branches
    Eliminate problem branches first. This step gives you a clearer view of the remaining structure: Remove any wood that’s clearly dead, shows signs of disease (like cankers), or is broken. This cut is crucial for tree health.
    Prune branches growing straight up, known as “water sprouts” (they rarely bear fruit), or any branches growing inward toward the tree’s center. They can overcrowd the canopy. You should also prune branches that cross over or rub against each other, which can create wounds that serve as easy entry points for pests and diseases.
  3. Open the canopy for sunlight and air
    The main goal of winter pruning is to create an open structure that lets sunlight and air reach inside the tree. Form a “vase” or Christmas tree shape for peach, plum, and cherry trees by removing the central upright leader to develop an open bowl shape.
    On the other hand, creating a central leader is critical for apple and pear trees. Maintain a main vertical trunk (leader), but ensure upper branches are shorter than lower branches to create a pyramid or Christmas tree shape that prevents shading.
  4. Use correct cutting techniques
    Making proper cuts ensures the tree heals quickly. When removing an entire branch, cut just outside the branch’s collar (the slightly swollen ring of bark tissue at the branch’s base). It contains the specialized cells the tree uses to seal the wound. Don’t leave a stub or cut flush to the trunk. When shortening a branch, cut just above an outward-facing bud. This cut directs the new growth away from the tree’s center, helping to open the canopy.
  1. Prune to control vigor
    Heavy winter pruning encourages vigorous new growth in spring. If your tree is healthy and growing quickly, limit cuts to 10-20% of the wood. If the tree is older and has minimal new growth, a more severe prune (up to 30-50% for stone fruits) can promote the growth of new, productive fruiting wood. As a general rule, however, never remove more than one-third (33%) of the tree’s overall canopy in a year to prevent severe stress.
  2. Use Sharp, Clean Tools
    Sterilize your tools before starting and between trees. Clean your hand pruners, loppers, and pruning saws with diluted bleach or rubbing alcohol to prevent the spread of pathogens between trees. Also, keep tools sharp. Sharp tools make clean cuts, which heal faster. Dull tools crush and tear the wood, leaving ragged wounds that invite disease.
    Clean Up Immediately
    Remove debris immediately after pruning. Rake up and dispose of all the pruning branches, especially any diseased material. Leaving diseased branches or leaves on the ground allows pests and fungal spores to overwinter and re-infect the tree the following spring.

Pruning fruit trees differs from pruning mature shade trees. Pruning fruit trees is a powerful management tool that ensures a consistent, high-quality, easy-to-harvest crop. It also maximizes fruit production and quality, improves light and air flow, and maintains the tree’s structural integrity and lifespan.

1. Master the timing: late winter is best

Pruning cuts made too early in winter can create frost damage. Cutting closer to spring allows the wound to heal almost immediately when the tree breaks dormancy, reducing the chance of disease.

2. Start with pruning deadwood

Remove all deadwood and branches that show signs of disease or are broken. Also, prune branches that cross or rub against each other. They can create wounds that provide easy entry points for pests and diseases.

3. Open the canopy for sunlight and air

The primary goal of winter pruning is to create an open structure that allows sunlight and air to reach the tree’s interior. Create a “vase” or Christmas tree shape for peach, plum, and cherry trees by removing the central upright leader; create a central leader for apple and pear trees.

4. Use correct cutting techniques

Cut just outside the branch’s collar when removing a branch. When shortening a branch, cut just above an outward-facing bud, which directs the new growth away from the tree’s center, helping to open the canopy.

Essential Guide to Pruning During Plant Dormancy

Written by John Campanini on . Posted in Blog, Pruning/Trimming, Tree Care.

Plant dormancy is the resting phase of a plant’s annual life cycle. It typically occurs in response to environmental cues, such as shorter days or cooler temperatures. Dormancy is a survival strategy that allows plants to conserve energy and survive during harsh conditions. It’s characterized by a drop-off in energy use and primary plant functions—transpiration, photosynthesis, respiration, and so on.

The timing of plant dormancy varies depending on the plant species and the climate in which it is growing. Triggered by shortening day length and several deep frosts, plant dormancy in New England usually starts in late November and ends when plant buds swell in late March or early April—a stretch of about four months of relative calm for trees and shrubbery.  

Benefits of Dormant Pruning

 

Absent important stressors, such as water shortages, insects, disease, and pests, this four-month period is an ideal time to prune plants. Some benefits of pruning during plant dormancy include: 

  • Reduced stress on the plant — When a plant is dormant, it is not actively growing and is therefore less stressed by pruning.
  • Less sap loss — Dormant plants have less sap flowing through their systems, meaning there will be less sap loss when pruned.
  • Reduced risk of disease — Dormant plants are less susceptible to pests and diseases, so there is less risk of spreading disease when you prune them.
  • Better visibility of the plant structure — When a plant is dormant, it does not have any leaves, which makes it easier to see the plant’s structure and identify any problems that need to be addressed.

Set Specific Goals with Pruning 

Setting goals for pruning, regardless of when you do it, is critical. In addition to the general benefits described above, pruning during dormancy can also be used to achieve specific things, such as controlling the size and shape of the plant, encouraging flowering and fruiting, improving air circulation and light penetration, and removing dead, diseased, or damaged branches.

Overall, pruning during dormancy is an excellent way to improve the health and look of your plants without causing them too much stress. Some examples of plants that you can prune during dormancy are deciduous trees and shrubs, fruit trees, rose vines, and ornamentals. Remember that some trees, such as maples and birches, can bleed sap if pruned in late winter or early spring. Prune these trees in the summer after their leaves have fallen.

Tips on Pruning Dormant Plants

 

Pruning dormant plants can be dicey. Make sure the tree is entirely dormant before pruning, meaning the leaves have fallen off and no new buds are forming. Also, make sure you cut just outside the branch collar. That’s the swollen area at the branch’s base where it meets the trunk or another branch. Cutting outside the collar helps the tree to seal the wound more quickly.

Below are additional pruning tips:

  • Identify and remove any dead, diseased, or damaged branches. They can be a hazard and can also harbor pests and diseases.
  • Prune to improve the tree’s structure and shape. This effort can involve removing crossing or rubbing branches, thinning out crowded branches, and raising the canopy.
  • Make clean, sharp cuts. These types of cuts help trees heal quickly.
  • Avoid pruning more than one-third of the tree’s crown at one time. Doing so can stress trees and make them more susceptible to pests and diseases.
  • Use sharp, clean pruning tools. That helps you make clean cuts and reduces the risk of disease.
  • Avoid pruning in wet weather. That can increase the risk of disease.

Pruning during dormancy is an excellent way to improve the health and look of your plants without causing them too much stress. But dormant pruning can be a challenge no matter when you do it. Following the pruning tips described above can help you beat this challenge. If you’re unsure whether or not a particular plant can be pruned during dormancy, consult a qualified arborist or horticulturist.

Winter Pruning

Written by RITree on . Posted in Article, Pruning/Trimming, Seasonal, Tree Care. No Comments on Winter Pruning

Trees need good structure. Good structure will neutralize the harmful effects posed by wind, rain and gravity. And the basis for good structure in trees is to prevent structural defects from cropping up on the trunk and lateral branches. The worst of these are co-dominate stems, over-sized branches and cluster branches.

They are commonly found associated with young, fast-growing saplings. The goal is to nip them in the bud before they get bigger and more costly to eliminate later. Structural pruning should start the year following plant installation and be repeated every 4 years over the next 25 years. Use the following illustrations and definitions to help locate and manage by pruning any major structural defects on your young trees.

  • 1 Co-dominant stems: Two or more equal-sized stems competing for the leadership role at the top of the tree is a no-no. Like an orchestra guided by a sole conductor, only one stem is needed. Maintain a single central stem/leader by lopping off the weaker of the two. Maybe, if necessary, even remove one or two shoots located directly below the new leader to more strongly assert the latter’s dominance at the top of the tree.
  • 2 Over-sized branches: Stems fitting this description are easy to find. They are much larger in diameter than their brethren. Here’s a rule of thumb to help you to identify them. For sound structure, no stem should be larger than 50% of the diameter of the stem at the point of attachment. For example, if a 2 diameter-inch stem is connected to a 6 diameter inch- trunk, all is well. However, if a 4 diameter-inch stem is connected to the same 6 diameter- inch trunk, that’s a no-no. It’s growing too fast at the expense of the rest of the branches. You have two choices for correcting this problem. The first is to remove the obese branch entirely. The second option is to remove a portion of the offending limb, usually about a third of it. This will slow its growth by denying it the extra carbohydrate (energy source) found in the lopped off portion of the branch. Eventually the shortened branch will come into compliance with the stem diameter ratio mentioned earlier. TIP: The second option is usually selected when total stem removal will leave a huge gap along the trunk of the tree.
  • 3 Cluster branching: Two objects cannot occupy the same space at the same time. This law of physics also applies to trees. Unfortunately, this condition is a common problem on young trees, especially those with opposite branching patterns (maple, dogwood, catalpa, etc.,). Here’s a tip leading toward a solution. Alternate branching is far superior structurally to opposite branching. Strive to get young trees into this zig-zag branching arrangement through the routine removal of offending branches. Remember, as they increase in diameter, branches located opposite each other will eventually place a lot of stress at that point along the trunk. The stress can often lead to breaks. This is a big problem with the Callery Pear (Pyrus calleryana). It inherently produces this type of structural defect and shouldn’t be planted without a future commitment to training.

Pruning Shrubs

Written by RITree on . Posted in Article, Pruning/Trimming.

1 creates vertical tunnels to improve light penetration and air movement throughout the shrub, 2 rids the plant of its weakest, unproductive stems and 3 promotes the new growth (stems) at the stem base from latent buds. Eventually, the new stems will grow taller, add girth and fill the spot left vacant by the removal of the original stem. The rule of thumb is to eliminate approximately 1/3 of the oldest stems each year. Using this approach, the entire plant will become ‘younger’ by replenishing most of the oldest stems with new ones in three years. Let’s use the illustrations below to demonstrate the benefits of renewal pruning on a sheared shrub with dense growth on top and a “leggy” plant, in general.

  • 1 Sheared shrub with dense growth on top and many old, “leggy” stems. Renewal cuts shown in red slash line.

  • 2 The shrub showing the creation of vertical tunnels inside the canopy following the removal of the largest stems by pruning.

  • 3 Shrub grows ‘younger’ as healthy, thrifty stems grow from latent buds the next spring following renewal pruning.
