Proper Pruning in Late Winter

Proper pruning in late winter leads to strong, lush trees and shrubs in the springtime

Does pruning strike more fear in your heart than a trip to the doctor? Pruning sounds complicated, but once you understand the basic guidelines, the rest falls into place.

PROPER PRUNING IN LATE WINTER – KNOW WHERE TO MAKE THE CUT

Most people hesitate knowing where to make the cut. Discerning “where” does not mean which specific limb needs to be removed. It means where precisely on the branch the cut is to be made.

Every pruning cut should be made at the point where there is another branch, fork, crotch angle or new bud forming. Making the cut at a growth point reduces the chance of decay and uncontrolled growth. Directing new growth is the goal of pruning, not merely pruning to remove growth.

Pruning to this juncture removes tall overgrown limbs, reduces plant height and thins out the plant. When extreme weather impacts our neighborhoods, pruning will reduce the weight of snow, ice and wind, which can lead to branch failure.

The energy that once supported the removed limb is now channeled into the growth of the remaining limbs. It is important to understand the concept of directional pruning.

The direction of the remaining limb or bud will point to where the growth will head. Attempting to control height? Prune to a side-pointing limb. Need to reduce spread? Prune to an upward pointing limb. Tired of the low-hanging limb hitting you in the face? Find a branch growing upward. See how this works?

Removing a limb back to another branch thins out a tree or shrub for better light penetration and less wind resistance. Not only does this apply to shade trees, but flowering and fruit trees as well. More sunlight penetrating the plant will lead to more flowering and fruit development.

HOW TO MAKE THE CUT

Now that you are confident in knowing where to make the cut, the next step is to do it properly. Pruning is an injury to the plant or tree, wounding the wood. The goal is to quickly heal the wound with a correctly made cut.

Pruning cuts are made slightly beyond the branch collar, where a layer of cambium growth has the ability of rapidly sealing off the cut. The branch collar is the raised, rough growth of bark tissue at the crotch angle. Remember, the cut is always made back to a branch angle.

Try to avoid cutting to the outside of the branch collar as it will leave a slight bump. We want to steer clear of creating a stub, a longer piece of wood sticking out. Stubs do not heal and lead to decay or uncontrolled growth. Cutting too close results in a flush cut, which removes the bark collar, leaving a bigger wound. A larger wound is slower to seal and increases the chance of decay.

Tree pruning is done in late winter before new growth. The lack of foliage reveals problem areas, making it easier to know which limbs to remove. Spring is a time of rapid growth for quick recovery. Now go forth and prune. I have confidence in your abilities.

Anatomy of a Tree

Leaves

Leaves carry out photosynthesis, making food for the tree and releasing oxygen into the air. And this tells us much about their shapes. For example, the narrow needles of a Douglasfir can expose as much as three acres of chlorophyll surface to the sun.

The lobes, leaflets and jagged edges of many broad leaves have their uses, too. They help evaporate the water used in food-building, reduce wind resistance and even provide “drip tips” to shed rain that, left standing, could decay the leaf.

Branches and Twigs

Branches and twigs grow out of the tree trunk and serve as support structures for leaves, flowers and fruit. They also transport materials between the trunk and the leaves.

Trunk

The trunk of a tree is made up of five different layers.

Anatomy of a Tree
  1. The outer bark is the tree’s protection from the outside world. Continually renewed from within, it helps keep out moisture in the rain and prevents the tree from losing moisture when the air is dry. It insulates against cold and heat and wards off insect enemies.
  2. The inner bark, or “phloem,” is the pipeline through which food is passed to the rest of the tree. It lives for only a short time then dies and turns to cork to become part of the protective outer bark.
  3. The cambium cell layer is the growing part of the trunk. It annually produces new bark and new wood in response to hormones that pass down through the phloem with food from the leaves. These hormones, called “auxins,” stimulate growth in cells. Auxins are produced by leaf buds at the ends of branches as soon as they start growing in the spring.
  4. Sapwood is the tree’s pipeline for water moving up to the leaves. Sapwood is new wood. As newer rings of sapwood are laid down, inner cells lose their vitality and turn to heartwood.
  5. Heartwood is the central, supporting pillar of the tree. Although dead, it will not decay or lose strength while the outer layers are intact. A composite of hollow, needlelike cellulose fibers bound together by a chemical glue called lignin, it is in many ways as strong as steel. Set vertically, a 1″ x 2″ cross section that is 12″ long can support twenty tons!

Roots

roots

Contrary to popular belief, tree roots are typically found in the top three feet of the soil. They also expand well beyond the dripline, often occupying an area two to four times the size of the tree crown.

A tree’s root system works to absorb water and minerals from the soil, anchor the tree to the ground, and store food reserves for the winter. It is made up of two kinds of roots: large perennial roots and smaller, short-lived feeder roots.

Deer Damage

Deer Damage to Trees and Landscape

One of the most frustrating things to deal with this time of year is having a deer snack on your beloved plants! Even if you are the type of person to tolerate deer damage because you love them, beware!  Deer are creatures of habit.  Once they feel safe, and find a tasty snack they will visit regularly.

An increase in deer populations and a decrease of their natural habitat have set up a situation in which your favorite landscapes become alternative food sources for deer.  As winter approaches and food sources become scarce, feeding on leaves, stems, and buds of plants become more apparent.  Male deer also cause damage by rubbing their antlers along the trunks of trees, stripping off bark. Deer should be discouraged immediately.  Trees and shrubs can suffer permanent damage.  Deer damage is usually identified by the torn or jagged appearance of branches

There are four ways to discourage deer: Fencing, repellents, predators, and deer-resistant plants. 

Fencing requires you to enclose your entire yard with a fence at least six feet tall. This is not necessarily an aesthetically pleasing option and also not cost effective. In some cases, you can put barrier fencing around these individual plants. While it is still unsightly, protecting a tree while it is young is important. 

Homemade and commercial repellents are common control methods to discourage deer, but their effectiveness vary. Snow and rainfall wash them away, so frequent applications are needed. Also, if food sources are scarce, deer may simply ignore the repellents, despite the taste or odor.

As far as predators go, a  noisy dog is a good deer deterrent.  If you don’t have a dog, you can hang shiny tape from branches, or place inflated balls, and other moving objects in the yard to startle deer with sudden movement.  You’ll have to rotate these frequently, however, or deer will soon realize that they are not in danger from these objects.

 If they are hungry enough and food is scarce enough, deer will eat almost anything.  However, there are a number of plants that deer don’t find particularly palatable.  Using these plants in your landscape is often the most cost-effective, least time consuming, and most aesthetically pleasing solution.

Below is a list of trees and shrubs not favored by deer.  However, resistance of any plant species may change due to environmental factors.

Seasonal needle drop

Seasonal Needle Drop in Trees

We’ve noticed an increase in calls concerning yellowing needles in customer’s evergreens, especially White Pines. However, the “problem” is simply seasonal needle drop in trees. This is a normal and natural process in evergreen trees. Every year, evergreens experience a seasonal needle drop that is a normal part of the plant’s cycle. Older needles on the inside of evergreen trees are shed each fall after they turn yellow, brown, or reddish-tan in color. Sometimes this natural process is very subtle and goes unnoticed because only the innermost needles area affected. The change can be gradual, or, with some species, quite rapid. Seasonal needle drop in trees can cause concern to homeowners who are not familiar with this natural occurrence.

White pines show the most dramatic needle drop change! Their annual loss of needles can be especially alarming, as the number of yellow needles outnumbers the tree’s green growth. This can be very worrying to a tree owner! Typically, white pines will retain needles for three years, but in autumn, 2-or-3-year-old needles will change color and drop, leaving only the current season’s growth still attached.  

So if you are seeing your evergreen trees drop yellow needles, this is part of their natural process. However, if you are seeing widespread decay within your tree, then please call the office to schedule an estimate at the phone number listed below. We will be more than happy to take a look at your trees to ensure their health and wellbeing.

Arborist pruning a tree

Mature Tree Pruning

Mature tree pruning removes dead and dying branches to maintain plant health and safety

All About Trees is a full-service tree care company, and one of our services is the pruning of mature trees. Thinning and raising are two types of tree pruning that should be performed periodically. It works to improve the form and shape of the plant, to eliminate interference with objects and structures, and to compensate for structural weaknesses. Thinning is the removal of live branches to reduce density. Research shows that thinning significantly reduces wind resistance and subsequent storm damage. This leads to healthier trees less prone to breakage, which will lead to a longer-lasting tree.

The pruning of lower branches, known as raising, can be used to increase the amount of light to turfgrass and ground covers beneath the crown of a tree. This will allow homeowners to improve the health of other plants within their yards, and improve tree health. In evergreen trees experiencing fungal issues, a small crown raise can be used to increase the airflow under the tree to reduce fungus. This also allows the tree limbs to be lifted off the ground, making the direct spread of fungus more difficult.

All About Trees arborists are trained to evaluate the condition of your trees and determine the type(s) of pruning required. We aim to balance your goals and those of managing plant health and safety. If you would like an estimate to have your trees pruned, please call the office at 417-863-6214. Our office hours are Monday-Friday, 8:00 am – 4:00 pm. If you miss us, please leave us a detailed voicemail message with your name, address, phone number, email, and tree concerns.

FALL COLOR

Predicting the peak of fall color can be difficult. Missouri is blessed with a great variety of trees, shrubs, and vines. Their leaves turn at different times, so Missourians enjoy a fall color season that may last four to six weeks. Sassafras, sumac, and Virginia creeper are some of the earliest to change, beginning in mid-September. By late September, black gum, bittersweet, and dogwood are turning.

The peak of fall color in Missouri is usually around mid-October. This is when maples, ashes, oaks, and hickories are at the height of their fall display. Normally by late October, the colors are fading and the leaves beginning to drop from the trees. Fall color is usually finished by the middle of November.

The progression of color change starts earliest in north Missouri and moves southward across the state. Generally, the color change is predictable, but it can vary from year to year. Much depends on the weather.

WHERE’S THE BEST PLACE?

You can enjoy Missouri’s fall color almost anywhere.

  • For spectacular vistas, choose routes along rivers with views of forested bluffs, and along ridges with sweeping scenes of forested landscapes.
  • On a smaller scale, drive on back roads, hike, or take a float trip under a colorful forest canopy on a clear, blue-sky day. Visit MDC Conservation Areas and Missouri State Parks.
  • Even treeless areas, such as prairies and roadsides, display beautiful shades of gold, purple, olive, and auburn with autumn wildflowers, shrubs, and curing, rustling grasses.
  • If you can’t get out of town, enjoy places with mature trees, such as older neighborhoods, parks, and even cemeteries.

Find events on your route

The Missouri Division of Tourism’s online calendar is packed with events happening all across Missouri this fall. Find those along your preferred routes.

Emerald Ash Borers

Emerald Ash Borers : Pest 101

Be on the lookout for emerald ash borers. The emerald ash borer (EAB) is a serious threat to ash trees in Missouri. This invasive pest will eventually kill unprotected ash trees. Many trees can be saved with the careful use of systemic insecticides. However, not all ash trees should be treated, and for many locations the start of treatments should be delayed. This guide will assist you in making decisions about protecting your trees from this invasive pest. Find more information at eab.missouri.edu.

In the Ozarks, we are proud of our trees. But a small insect is putting our beautiful ash trees at risk. The emerald ash borer is an invasive pest that will eventually kill unprotected ash trees. Treating your tree early can help save it.

Here are a few signs to know if emerald ash borers have affected your tree:

  • D-shaped exit holes about 1/8″ wide.
  • Winding, s-shaped tunnels just under the bark.
  • New sprouts on the branches and lower trunk.
  • Increased woodpecker activity on the tree.
  • Sparse leaves and/or branches dying in the upper part of the tree.

Black Walnut – Springfield, MO

BLACK WALNUT
Juglans nigra

Family

Juglandaceae (walnuts)

Description

A large tree with a straight trunk and rounded, open crown. The nuts, spicy odor, large feather-compound leaves, and chambered pith in the twigs help identify it.

Leaves alternate, compound, 1–2 feet long, with 11–23 leaflets. Leaflets 3–5 inches long, 1–2 inches wide, broadest below the middle, the end leaflet smaller than side ones or absent; margin toothed; upper surface yellow-green; lower surface paler, hairy.

Bark grayish-brown or black, grooves deep, ridges broad with sharp or rounded edges, roughly forming diamond-shaped patterns, chocolate-colored when cut.

Twigs stout, rigid, brown to gray-brown, hairy; end bud about ½ inch long; pith light brown, chambered when cut lengthwise.

Flowers April–May. Male flowers in catkins, female flowers in a short spike on the same tree.

Fruits September–October, usually single or in pairs. A green rounded husk, 1½–2½ inches across, covers the round, hard, bony, dark brown or black nut. The kernel is oily, sweet, and edible.

Similar species: Butternut, or white walnut (Juglans cinerea), is scattered and declining in the eastern two-thirds of Missouri, mostly in low and moist soils. It has rather cylindrical fruits, and the nut inside has 4 lengthwise ribs; leaf scars have the upper edge straight (not notched), bordered by a well-defined velvety ridge. The mild-tasting English (or Persian) walnut is the species J. regia. It is native to Eurasia and when cultivated in Missouri does not escape. The state of California grows nearly all of the US commercial supply of English walnuts. Walnuts are in the same family as hickories and pecans.

Key Identifiers

 

  • Leaves long, alternate, feather-compound
  • Leaflets 11–23, toothed
  • Fruits distinctive
  • Bark grayish, deeply grooved with rather diamond-shaped patterns, ridges broad
  • Twigs stout, with chambered pith
  • Distinctive spicy odor
Size

Height: to 90 feet.

Missouri is the world’s top producer of black walnuts, which are used in baking and confections, and even pickled whole! It would be eaten by more people it getting the nutmeats out of the nut was easier. Walnut is the finest wood in the world. In the past, warm brown hardwood was used lavishly in homes, barns, and fences. Today it’s used for furniture, veneer, and gunstocks.

The nuts are eaten by mice and squirrels. The leaves are eaten by larvae of luna moths, regal moths, and others. The presence of such caterpillars naturally attracts warblers and other insectivorous birds. Walnut trees produce a chemical, juglone, that stunts or kills other plants growing nearby.

Black walnut has been designated as Missouri’s official state tree nut. Most of the state’s large, old walnut trees were felled in previous decades for lumber and other uses, yet the superb wood from this species remains in high demand. Young landowners have been planting walnuts in hopes of harvesting them in future decades. Several serious pests may endanger the health of Missouri’s walnuts; educate yourself about thousand cankers disease (TCD), ambrosia beetles, walnut anthracnose, and other diseases, and never, ever transport firewood.

HABITAT AND CONSERVATION

Black walnut grows throughout Missouri in a variety of soils. It grows best on the deep, well-drained soils of north Missouri and on alluvial (river-deposited) soils in the south. Every farm in the state should grow some walnut trees. In addition to providing quality wood, the walnut’s nutmeats are a major industry in the state. Even the hard shells can be used as an abrasive and to make activated carbon.

It is a common misconception that tree services will pay the customer for removal of black walnut trees, due to their high-quality wood. However, this is not true. We at All About Trees will not pay to remove your black walnut tree.

Springfield, MO Tree Alert – Japanese Beetles

 Springfield, MO Tree Alert- Japanese Beetles

Tree species affected: Japanese beetles are known to feed on over 300 plant species. Linden (basswood), elm, crabapple, sycamore (planetree), sassafras, plum, cherry, and bald cypress are commonly damaged, as well as grape and rose.

Concerns: Lacy, skeletonized leaves. Partial or entire defoliation.

Description: Japanese beetles feed on the upper surface of leaves, leaving behind veins. Damage is frequently seen near the top of the tree or plant first. These beetles often feed in groups.

Insecticides are not compatible with trying to maintain a pollinator-friendly yard and should never be used on flowering plants or trees that will attract bees and other pollinators.

Frequently Asked Questions

What is the lifecycle of the Japanese beetle?

Japanese beetles spend most of their one-year lifecycle under-ground as a white, c-shaped grub. These grubs feed on grass roots and can damage turf if populations are high. Grubs pupate in late spring and emerge from the ground as adult beetles around mid-June in Missouri. These beetles congregate on host plants, particularly those in full sun. Japanese beetles congregate through a combination of pheromones released by females and floral scents emitted by the damaged host. After mating, each female beetle lays 40-60 eggs in the soil over the course of her 30-45 day lifespan. These eggs hatch into grubs in July and August. Most adult Japanese beetles are gone for the year by mid-August.

Will Japanese beetles kill my trees?

Healthy, established trees can typically tolerate a heavy amount of feeding damage. However, this damage is a source of stress for trees. You can help your trees by watering them 2-3 times per month during dry times to avoid additional stress from drought. A good rule of thumb is ten gallons of water per inch of a tree’s diameter.

Should I use a Japanese beetle trap?

Be cautious when using Japanese beetle traps as they are very effective at bringing beetles in from areas well outside of your yard. Traps don’t catch all the beetles they attract, so nearby plants may be heavily damaged. If you decide to use a trap, place it at least 100 feet away from plants you want to protect. Dispose of trapped beetles frequently by dropping them into a bucket of soapy water.

If I control the Japanese beetle grubs in my lawn, will I have fewer beetles next year?

Controlling Japanese beetle grubs in your lawn won’t significantly reduce the number of beetles you see next year. Japanese beetles are strong fliers and can continue to fly in from neighboring areas over a mile way. Grub control may have more of an impact if you live in a forested area where turf grass is uncommon.

How can I control Japanese beetles?

For light infestations on shrubs and young trees, handpicking is an effective method of control. Beetles are typically sluggish and easy to capture early in the morning. Shake stems and branches with Japanese beetles over a bucket of soapy water.

Several contact insecticides are available for control of Japanese beetle adults (e.g. acephate, carbaryl, cyfluthrin, permethrin); check the label to confirm Japanese beetles and your plant species are listed. These chemicals may need to be reapplied at labeled intervals, especially in hot or rainy weather. Organic products containing azadiractin and spinosad are effective deterrents for a few days. Neem oil may be useful in deterring beetles from feeding if used at the first sign of damage.

Systemic insecticides, such as those containing imidacloprid, can be applied as a soil drench to protect some types of trees from Japanese beetles (follow all label restrictions). However, this product would need to be applied in early June in order to be effective since it can take 4-6 weeks for a tree to translocate the chemical from soil to the leaves.

Due to impacts on pollinators, systemic insecticides should not be applied before or during the bloom period on any plant. In addition, use of many IMIDACLOPRID products (e.g. Bayer Advanced Tree & Shrub Insect Control) is NOT ALLOWED on LINDEN (BASSWOOD), a common host tree of Japanese beetles. Product labels contain new restrictions due to frequent misuse and impacts on pollinators.

Are there any biological controls for Japanese beetles?

No biological controls are currently available for managing adult Japanese beetles. Two products are available for biological control of Japanese beetle grubs in the soil. Neither product is 100% effective.

  • Milky spore (milky disease bacteria) is a long-term control technique that can help reduce grub populations in 2-3 years. Introduce milky spore into several spots in your yard in a grid pattern. Once in the soil, the spores will be present for many years. Milky spore requires specific temperature and moisture conditions to infect grubs, so effectiveness varies.
  • Nematodes of the Heterorhabditis strains will attack grubs. Because soil moisture is critical for nematode survival, it can be difficult to maintain proper conditions for nematodes and avoid overwatering plants. Nematodes need to be applied every year up to three times during the grub stage.

What should I do next year to protect my trees?

Keep an eye out in mid-June for Japanese beetles. Handpick beetles off small or newly planted trees. Preventing early feeding damage can protect trees in the following weeks. If populations are too high to remove by hand, spray an insecticide labeled to control Japanese beetles on your particular tree species. Repeat, if needed, at labeled intervals.

For large established trees, help reduce stress caused by Japanese beetle feeding through good tree care practices: water trees 2-3 times per month during drought conditions, avoid wounding by mowers and weed trimmers, and, if used, keep mulch rings no deeper than 3”.

Do weather conditions impact Japanese beetle populations?

Drought conditions in July and August can lead to the death of many newly hatched grubs. During severe droughts, irrigated areas and some low-lying wet locations may be the only places that grubs survive. Harsh winter conditions can also be a limiting factor in Japanese beetle grub survival. Grubs are killed when soil temperatures reach 15°F or when soils remain near 32°F for two months, (snow cover can significantly insulate soils from frigid air). A cold winter without much snow could greatly reduce the following year’s adult beetle population.
