Effects
Definition
- Pruning, like any other skill, requires knowing what you are doing to achieve success. The old idea that anyone with a chain saw or a pruning saw can be a landscape pruner is far from the truth. More trees are killed or ruined each year from improper pruning than by pests. Remember that pruning is the removal or reduction of certain plant parts tha...
Prevention
- The necessity for pruning can be reduced or eliminated by selecting the proper plant for the location. Plants that might grow too large for the site, are not entirely hardy, or become unsightly with age should be used wisely and kept to a minimum in the landscape plan. Advances in plant breeding and selection in the nursery industry provide a wide assortment of plants requiring littl…
Risks
- There are many kinds of hand pruning shears. Most of them are designed for cutting stems up to 1/2 inch in diameter. Attempting to cut larger branches risks making a poor cut and/or ruining the shears.
Varieties
- Two common styles of hand shears are the scissor action and the anvil cut. In scissor action shears, a thin, sharp blade slides closely past a thicker but also sharp blade. These usually cost more but make cleaner, closer cuts. In anvil cut shears, a sharpened blade cuts against a broad, flat blade.
Types
- Lopping shears (loppers) have long handles that are operated by both hands (Figure 1). Even the least expensive can cut material 1/2 inch in diameter. Better ones can slice through branches of 2 inches or more, depending on species (i.e. oak is tougher than ash) and condition (i.e., dead wood is tougher than live wood until decay sets in).
Equipment
- Pole pruners usually have a cutter with one hooked blade above and a cutting blade beneath, similar to a large pair of lopping shears. The cutter is on a pole and is operated by pulling a rope downward. Poles can be made of several materials and can either be in sections that fit together or that telescope. Wooden poles are sturdy but heavy, while aluminum poles are light but can co…
Safety
- Use of pole pruners can be dangerous. Material cut overhead can fall on the operator (unless it hangs up in other branches). The user should exercise caution and wear head and eye protection.
Uses
- Hedge shears are used mainly for shearing plants into hedges or formal shapes. The most common type is manually operated; however, if large areas of hedges are involved, power-driven shears may be more practical (Figure 3). Pruning saws, both rigid or folding, are very useful for cutting larger branches that are too large for hand shears. Tree saws are available for removing l…
Other
- Other tools, which are sometimes necessary, are chisels, gouges, pruning knives and mallets. These all come in handy when repairing storm damage wounds or other wounds.
Construction
- Most woody plants fall into two categories based on the arrangement of the buds on the twigs and branches. In general, the bud arrangements determine the plantss typical growth habit. Buds may have an alternate or an opposite arrangement on the twigs. A plant with alternate buds usually is rounded, pyramidal, inverted pyramidal, or columnar in shape. Plants having opposite …
Management
- To open a woody plant, prune out some of the center growth and cut back terminals to the buds that point outward. In shortening a branch or twig, cut it back to a side branch and make the cut 1/2 inch above the bud. If the cut is too close to the bud, the bud usually dies. If the cut is too far from the bud, the wood above the bud usually dies, causing dead tips on the end of the branches…
Purpose
- All too often trees are topped (dehorned) to reduce size or to rejuvenate growth. In either case topping is not a recommended practice; in fact, some refer to it as the Texas chain saw massacre. Topping is the process whereby a tree is cut back to a few large branches. After 2 to 3 months, regrowth on a topped tree is vigorous, bushy and upright. Topping seriously affects the trees str…
Benefits
- Thinning is a better means of reducing the size of a tree or rejuvenating growth. In contrast to topping, thinning removes unwanted branches by cutting them back to their point of origin. Thinning conforms to the trees natural branching habit and results in a more open tree, emphasizing the branches internal structure. Thinning also strengthens the tree by forcing diam…
Variations
- The height of the lowest branch can range from a few inches above the ground for screening or windbreaks, to more than 7 feet above the ground near a street or patio. Removal of lower limbs is usually done over a period of years beginning in the nursery and continuing for several years after transplanting until the desired height is reached.
Structure
- Major scaffold branches of shade trees should be vertically spaced at least 8 inches apart and preferably 20 to 24 inches apart. Closely spaced scaffolds have fewer lateral branches resulting in long, thin branches with poor structural strength.
Advantages
- An experienced tree professional can easily distinguish between live and dead wood in winter. Winter pruning is often preferred because it is easy to visualize shaping when foliage is gone. Such work can also be done at a lower cost in winter because fewer precautions are necessary to avoid garden and flower bed damage and cleanup is easier.
Clinical significance
- Injuries to trees that expose the wood or kill the bark may allow insects or disease organisms to enter the tree. Proper treatment protects the tree and promotes faster healing. Few trees reach maturity without receiving one or more wounds from a variety of sources. Yet trees have survived for centuries to become the oldest living creatures on earth despite wounding. Some recent wor…
Treatment
- Homeowners can help the plant compartmentalize the damage more rapidly than it does in nature. If bark has been crushed or stripped from the trunk, remove the injured bark, shape the wound. Cut away all damaged bark and remove isolated scraps from the wound area. For fastest healing, shape the edge of the wound, as nearly as possible, to an elongated ellipse. If this shap…
Prognosis
- For a year or more after a tree has been struck by lightning, it is often difficult to determine the extent of damage since much of the injury may be internal. Trees that seem badly damaged may live while others apparently only mildly injured may die. If the tree can be saved, remove all shattered parts and damaged limbs; then smooth and paint exposed wood.
Cultivation
- The general pruning procedure shown for crape myrtle (Figure 9), applies to many large shrubs and small tree species.
