What Are the Advantages of Tree Pruning?

It defies logic that you should prune your plants by removing branches, leaves, and even roots in order to encourage growth and development. However, it is also one of the most crucial things you can do for a healthy garden and lawn.

If done properly, pruning might encourage further development. When you prune above specific nodes or locations along each plant structure, the plant's growth hormones are stimulated, allowing the plant to heal and rebuild the severed tissue.

Let's take a look at why pruning is so effective in promoting new growth, as well as how you may employ selective pruning to influence the form and yield of your plants.

What Is Pruning?

To prune is "to remove or reduce branches or other growth on a plant so that it is more uniform in form or yields more fruit." It could require severing limbs or uprooting the entire thing. Each has the potential to either help or harm the tree. To prune properly, one must have a firm grasp on tree biology.

How Pruning Promotes Growth

Meristems are tiny tissue structures found in plants. Every new shoot originates from one of these meristems.

Pockets of cells with an undetermined fate are called mesenchymes. They have the potential to develop into any kind of plant or animal tissue. The fate of cells within a meristem is controlled by hormones.

There are three distinct meristem types:

• Apical Meristem- Any branch, stem, trunk, or root can be traced back to its apical meristem. Also, they can be discovered in the nodes of leaves. These trigger the expansion of a plant's dimensions and depth, as well as the expansion of its leaves and blossoms.
• Intercalary Meristem- Grass can be cut short and grow back from its crown (or base) because of a special type of meristem found only in monocots.
• Lateral Meristem- The lateral meristem exists in the epidermal layer of the plant's stems, roots, and branches. When a plant thickens up, it's because of this meristem.

Apical dominance is induced by a hormone secreted by the apical meristem. The growing point of a stem sends a hormone down the branch or trunk to the other nodes, telling them to start making leaves, flowers, thorns, etc., so that the entire plant can continue to expand.

By severing the apical meristem, hormone production is halted. As a result, nodes along the branch or stem may produce more stems and branches, thus increasing the plant's height or length.

When plants are pruned, it might send a signal to their meristems to produce new growth. Usually, this is done by slicing above a node on a leaf.

If you cut a plant and let it heal, instead of producing leaves or flowers, the meristem will start growing new stems. In the event that the apical meristem is lost, new branches may develop from the branch or stem's other nodes.

Pruning Techniques that Promote New Growth

How come knowing about meristems is crucial? Why not just lop off a piece of the tree and cross your fingers?

There are nodes and internodes on every stem, twig, or trunk. In plant anatomy, a node is a growth point while an internode is really the segment between nodes.

In order for an internode to heal, it must be severed close to its node. The meristem is not self-healing, thus if the node is damaged, the healing process will stop.

New plant tissue is generated as a result of the interaction between healing and hormones in the plant.

To promote recovery and stimulate new growth, pruning should be performed just above a node. Because of this, most pruning instructions will tell you to make your cut directly above a leaf or leaf bud, at an angle that points upward and away from the leaf.

The meristem is safeguarded and infection risks are reduced at this angle.

The remaining portion of the stem will dry out or perish if you make an internode incision and leave more than a quarter of an inch of tissue above the node. If an infection spreads up the stem, the node below it will die.

There are a few rules to remember while cutting back a stem or branch:

• Choose the nearest node and choose the desired length of the stem or branch.
• The leaf node should be positioned 1/8" - 14" (or more) above the cutting tool, and the pruners should be held at an angle up and away from the node.
• With one swift action, cut off the stem or branch. Using dull pruners will result in jagged, damaged tissue.

Location is only part of the story when it comes to fostering development. You can harm the node and stunt growth if you prune at the bad time of year.

You should consult your plant's annual maintenance schedule before doing any pruning. Generally speaking, deciduous plants benefit most from being pruned between the seasons of spring and fall.

How to Manage Growth by Pruning

Light pruning helps keep plants from taking over, gets rid of dead or diseased parts, and thins out water sprouts. In order to maintain their health and confinement, this is suitable for most woody shade trees, shrubs, and perennials.

Shape, flower/fruit production, and root depth are all things that can be managed with proper pruning. In-depth pruning, which involves the manipulation of meristems and hormones, is required if you want to take your plant care beyond the superficial level and actually affect its health and form.

Flowers/Fruit

Increased flower and fruit set can be achieved, and the placement of flowers and fruit can be moved throughout the plant with the help of strategic pruning.

The Wood's Age

Flowers and fruit are produced by many fruit trees, bushes, and vines only after a specific amount of growth has occurred. Apple trees, for instance, develop fruiting spurs on timber that is at least two years old.

While considerable fruiting can be done on spurs for 6–10 years, it is best to prune to allow some regeneration each year.

In contrast, peaches produce fruit in their first year of growth. Since peach trees don't produce fruit on wood older than a year, you can perform severe pruning on them. If you want more blossoms and fruit from your plants, heavy trimming is the way to go.

If you want blooms and fruit from a shrub, tree, or vine, you'll need to know how old the wood has to be before you may prune it.

If your plant blooms or produces fruit on fresh growth in its first year, you can trim it hard to promote rapid development.

If you want to put flowers or fruit on older wood, you should first remove any stems or branches that aren't structurally necessary, then prune systematically each year to keep the older wood intact.

Light

Because most flowering plants and fruiting plants require light, you should prune such that the interior of the plant is open to air and light.

To keep the plant in a full form that promotes a favourable environment for flowering and fruiting, trimming should begin within the plant before moving to the exterior branches or stems.

Stems

While some plants' leaf patterns alternate, others' do not, and vice versa. When sculpting your plant, this information is crucial.

If you make an arbitrary cut over a node in an alternate leaf design, one stem will sprout from node and continue developing in the way the leaf might have grown had you not made the cut.

If you trim above the leaf nodes of a plant with a pattern of alternating leaves, you'll be left with two stems that grow in opposing directions, in the same way the leaves might have grown had you left the plant unpruned.

While pruning an alternate-leaf plant, select a node that lies along the line of growth you wish to encourage. Select the node either above or below to prune if you want it to go in the opposite direction.

By leaving both nodes intact and encouraging the development of very slender new stems bearing many leaves, a plant with an opposing leaf pattern can be pruned to achieve a highly full, bushy outer growth.

If you wish to guide or shape the new development, however, you may gently wipe off one node and let the surviving node produce a new stem.

Roots

When roots are pruned, they adapt by becoming more fibrous and deep. Roots are able to sense when there is pressure on the plant's growth from above ground because of how hormones are released during the healing process following a cut.

Whenever a plant senses danger, its roots will adapt by expanding their root systems to draw in more water and nutrients, allowing the plant to continue to grow and potentially survive.

Some plants benefit from having their roots pruned directly using a shovel or pruners, while this is not advised for others.

Pruning is an essential part of plant management, but it does require a fundamental understanding of plant structure. If you don't know how a shrub or tree will react to pruning, it's best to let it develop naturally.

When is the best time of year to prune?

Learning when and how to prune plants is crucial. Plants are more likely to be beautiful, healthy, and productive when the timing is just right. Below, you'll find indicators of when it's ideal to prune various plants in your yard and garden.

The plant's growth habit, when it blooms, and its overall health or condition all play a role in determining the right schedule to prune deciduous shrubs.

Shrubs that produce flowers in the spring, including such lilacs and forsythia, do so on new growth that occurred during the previous season. When spring-flowering shrubs should have their branches pruned depends on the plant's overall health and condition.

To revive or renew neglected, overgrown spring-flowering bushes, severe pruning is often necessary. Rejuvenating huge, overgrown plants is best done in the late winter or the early spring (March or April). For the next two or three years after harsh winter or springtime pruning, flower production will be minimal at best. But rejuvenation pruning will get the shrubs back to full health.

Pruning well-kept, spring-flowering shrubs is best done right after they finish blooming. Only minimal to moderate trimming is needed to maintain a healthy, well-cared-for shrub. By waiting until after the blooms have faded to prune, gardeners miss out on the showy spring flowers and the shrubs don't have enough time to set fresh blossoms for next year.

In the summer, shrubs like potentilla or Japanese spirea bloom on the new growth from the previous year. Shrubs with summer flowers should be pruned in early spring or late winter. The shrubs can be clipped so that they bloom on this year's growth in the summer.

It's true that not all deciduous bushes provide visually pleasing blossoms. Shrubs can be distinguished by their bright bark, fruit, or leaves. These bushes are best pruned in the autumn or early spring, before they start growing again.

Never perform late-summer pruning on deciduous bushes. Shrubs could benefit from a late growth spurt if they are pruned in August and early September. The new growth may be vulnerable to winter harm if it does not harden properly before the onset of cold weather.

Evergreen trees like pines, fir, and spruce rarely need to be trimmed. Remove any branches that are damaged, diseased, or otherwise not in good health. The best time of year to prune lower branches off of evergreen trees is in the late winter.

The most recent (external) growth on spruce or fir trees is adorned with side buds. Pruning back shoots in early spring to a point over a lateral bud and side branch encourages denser growth.

Pine trees, like other conifers, sprout new growth from buds at their tips. Pines are unique in that they do not have lateral buds. Pinching or trimming off between half and two-thirds of the pine tree's extended terminal buds "candles" in spring, whenever the candles are about 2 to 3 inches long, would inhibit the tree's growth. New growth would not form if you prune back to the older wood further down the stem.

Conclusion

Pruning means "to remove or reduce branches or other growth on a plant in order to make it more uniform in form or yield more fruit." Both chopping off branches and uprooting the tree have the potential to either help or hurt the tree. If you cut a plant and let it heal, the meristem will begin growing new stems rather than new leaves or flowers. Every single stem, twig, and trunk has nodes and internodes. A node is a growth point in a plant, and an internode is the part of the plant that lies between nodes.

Pruning is most effective for deciduous trees and shrubs in the spring and fall. Deep pruning is a technique used to improve the health and appearance of a plant by intervening with its meristems and hormones. All woody shade trees, shrubs, perennials, and even some fruit trees can benefit from this. Flowers and fruit won't set properly on non-essential stems and branches, so prune them off before planting on older wood. The roots of some plants should be cut back with a shovel or pruners, while others should be left alone.

Proper pruning of well-maintained spring-blooming shrubs should be done as soon as possible after the plants have finished flowering. A well-cared-for shrub requires only light pruning to stay healthy. Plants that have grown uncontrollably should be pruned in late winter or early spring. Shrubs such as potentilla and Japanese spirea produce flowers on their new growth in the summer. Deciduous shrubs should never have their branches pruned in the late summer. Late winter is the best time to trim the lower branches of evergreen trees.
