Tree Care- What is an effective way to eliminate sucker growth?

Posted by Rachael Monico on Tue, Aug 18, 2015 @ 06:00 AM

Tree sucker growthSucker (basal shoot):
  • A fast growing shoot or stem that grows underground from a plant that causes the tree to weaken by draining water and nutrients 

 

Why do they occur?

  • Suckering is a tree's self-defense mechanism in response to stress to the following:
    • Drought
    • Over fertilization
    • Excessive watering 
  • Due to an exposed graft union (the area where 2 plants have grown together for hardiness benefits)

Removal 

Prune shoots after they are identified as they grow rapidly and become large quickly 

  • Remove small suckers by hand using a twisting motion. The lack of clean cut makes it more difficult for new suckers to grow
  •  Larger shoots may require hand pruners, loppers or even a hand saw.  Be careful not to damage the bark. When making a cut, get as close to the ground or even underground if possible. Open wounds exposed to sunlight can trigger more sprouting
  • For shoots that are sprouting feet away from the base of the tree, mow over slowly or use a sharp spade to dig out the tree root that is causing the issue. Be careful not to damage nearby healthy roots
  •  Mechanical ways of shoot removal are the safest and most effective methods. If you prefer chemical controls, contact a licensed arborist for a recommendation

Prevention

Most trees are susceptible to suckering if they are exposed to stress but you will find certain trees are prone to suckering such as Crabapple, Linden, Maple, Lilac, and any fruit trees that are grown on a graft union. Although suckering is inevitable for some trees, there are steps you can take to help minimize suckers, prevent them all together, and improve your tree care.

  •  Check the root ball of the tree when you are purchasing it to be sure the tree is planted at the proper depth.
  •  Make sure new trees do not have sucker growth already
  •  Water and fertilizer at recommended levels.
  •  Keep two inches or more of mulch around the tree to help stop sprouts from coming up through the ground.

Omaha Tree Care - Why do leaves change color in the fall?

Posted by Rachael Monico on Tue, Nov 05, 2013 @ 08:30 AM

CM's Ask the Arborist

Why do leaves change color in the fall? Why is fall color better in some years than others?

Green leaves actually contain colorful pigments all season, but during the growing season those colors are masked by an abundance of green chlorophyll.  Chlorophyll is used in photosynthesis, the process in which the tree uses sunlight to produce food.  The shorter fall days signal to the trees that winter is coming and it will soon be time to shed its leaves.  At this time the tree stops producing Chlorophyll and the colorful pigments that have been there all along are finally revealed.

 

October Glory Maple

The brilliance of fall color is affected mostly by the sunlight; however, temperature fluctuation and soil moisture also play a role.  A series of warm sunny days, followed by cold, but not freezing night time temperatures will produce the best fall color.  If the trees experience a fall with a lot of cloud cover and moderate temperatures, the color will be dull.  In addition, a wet spring followed by a moderate to dry summer and fall will produce the best fall color.  During late summer and early fall, if a tree is under a slight amount of stress due to dry soil conditions, it will have more brilliant color.

Ask the Arborist - Caring for Trees During the Winter Months

There are some steps you can take to prepare your tree to deal with the harsh winter conditions that we experience here in Nebraska.

Water: Watering through the fall months is always a good idea, but it is particularly important if we have experienced drought conditions during the summer months. The tree’s root system is still active and will take up Maple, Red Sunset fall 5water well into winter, so making sure water is available is vital to the health of the tree. It is also a good idea to water several times over the winter months, as long as the soil and air temperatures are above freezing.  Visit our blog for more information about watering trees in the winter and checking soil temperatures in your area.

Fertilize: The tree’s root system is still very active during the winter and will be using and storing nutrients that it takes up from the soil.  A fall deep root fertilizer application benefits the tree by making sure it has the necessary nutrients to get through the winter and to be ready to put on new growth in the spring.

Pin Oak

Tree Wrap: Extreme temperatures or hungry bunnies and squirrels can cause permanent damage to the tree’s trunk during the winter months.  Extreme fluctuations between day and night time temperatures can cause frost cracks on the trunk of the tree. If we have temperatures below freezing at night followed by a sunny, mild day, the bark can split when the sun heats up the south and/or west side of the tree.  This can cause the bark to expand too quickly. The wound caused by frost cracks can make the tree susceptible to disease or insect infestation.

Bunnies and squirrels like to snack on tree bark during the winter when food is sparse. They particularly like younger trees and trees with softer bark like Crabapple trees. 

Clump River BirchUsing tree wrap can protect the tree from harmful temperature fluctuations and animal damage.

Mulch: Mulch will act as a blanket for the tree’s root system. It will protect the root system from extreme cold temperatures. It will also help to keep moisture in the soil.  Typically, 2-3” will do the trick.  However, do not add mulch right up against the trunk as it is important to keep good airflow around the base of the tree to avoid rotting.

Tree Care Omaha - What Kind of Tree Should I Plant in My Yard?

Posted by Andrea Monico on Mon, Sep 30, 2013 @ 08:05 AM

Omaha Tree Care

 

There are a few important issues to consider when choosing a tree to plant.

What will be the mature size of the tree? 
All too often we see a tree that looked great close to the house when it was first planted but over the years grew too large for the site and had to have major limbs removed or even needed to be cut down.   If you

Japanese Lilacare looking to plant a tree near the foundation of your house, choose a tree with an appropriate smaller mature size. You could also choose a tree with an upright, columnar growth habit, such as a columnar white pine.

Are there any obstructions above the tree? 
While you are considering size, don’t forget to look up!  If there are power lines above your planting site, you will need to either choose a different planting site, or choose a tree that will not interfere with the power lines when it reaches its mature height.

 

Evergreen tree

What is the condition of the planting site?
Site conditions include the amount of sunlight that the tree will be exposed to, the moisture level of the soil, and if the site is protected from or exposed to extreme Midwest elements. For example, a Japanese maple tree will do much better in a protected shady location as opposed to a site that is exposed to harsh winter winds and hot summer sun.

 

 


What purpose will the tree serve?
Are you looking for a large tree to provide your house with afternoon shade or are you looking for a small tree to add ornamental value to your landscape? Many trees will offer more than one benefit. A large evergreen tree, for example, can provide a windbreak that protects a house from strong winter winds while providing shelter and nesting sites to birds like chickadees, cardinals, and finches.

Oak treeMany homeowners are looking for a fast growing shade tree so that they can enjoy the energy saving benefits as quickly as possible. It is important to keep in mind that fast growing trees tend to have softer wood than the slower growing trees and will not be as long lived as the hardwood trees. So, if you are looking for a tree that will provide shade for many years to come, you may be better off with a hard wood tree such as an oak as opposed to a soft wood tree like a birch.

Fall is a great time for planting trees! If you are interested in seeing how a tree will look when it has matured, the OPPD Arboretum has many examples of trees that do well in Nebraska.  If you would like more information about selecting the right tree for your property, please contact us!

Omaha Tree Care - Fall webworm

Posted by Rachael Monico on Thu, Sep 19, 2013 @ 07:23 AM

tree diagnosis omaha I've been told my trees have fall webworm.  Does this mean I will lose my tree?

 The damage done by the fall webworm looks much more devastating than it actually is. The webbing in the tree usually appears in late July or early August. The webbing starts at the ends of the branches and expands toward the trunk of the tree. Small black caterpillars are found devouring the foliage in and around the web. This activity leaves the tree looking very unsightly but not permanently damaged. In extreme cases, an entire tree may be defoliated. A healthy tree can withstand a fall webworm infestation for several consecutive years without suffering any major effects. A tree that has already been stressed or weakened by another pest may require action.

Generally speaking, fall webworms will favor fruit trees and ornamentals such as crabapple and pear trees. If the webbing is within reach, simply remove it with a stick, broom, etc. The areas of the tree that have been defoliated should leaf out with the rest of the tree next spring.

Tent caterpillar and Gypsy moth caterpillar are two types of pests that are very similar to fall webworm, but they are active beginning in the spring and will continue through the fall. Webbing usually begins in the forks of branches and expands toward the ends of the branches. These caterpillars can produce several generations during one season and should be removed when first noticed. 

If the webbing is out of reach or the tree is heavily infested, chemical control may be required. As always, we invite you to contact one of our licensed arborists for any tree care concerns you may have.

Apple Scab Leaf Disease

Posted by Rachael Monico on Mon, Jul 15, 2013 @ 11:15 AM

Ask The Arborist

My crabapple tree's leaves are turning black and dropping quickly. Is my tree dying?

Apple Scab leaf disease is most likely the cause of the leaf drop and will not kill the tree. The tree will most likely put on a second set of leaves this season. It is important to take steps to encourage good overall health of the tree to help it recover from the loss of leaves. Give the tree extra water during periods of extreme heat and less rainfall, avoid any injury to the tree or pruning for this season, and apply deep root fertilizer this fall. You may also want to consider preventive treatments for next spring.

apple scab leaf disease.3

Apple Scab is a leaf disease that thrives during cool, wet spring seasons. This last springbrought an extended period of cool, wet conditions which allowed the Apple Scab fungi to thrive. The spores are then spread during these ideal conditions and infect the leaf tissue. Once a leaf has been infected, there is not a treatment to cure the infection so the disease eventually causes the leaf to drop. If a tree is infected for several consecutive years, preventive treatments should be applied. Early leaf drop requires the tree to use extra energy to produce more leaves, which can become a problem if it happens continuously.

My Trees Look Healthy. Why should I have them treated?

Posted by Rachael Monico on Thu, Jun 13, 2013 @ 06:00 AM

Ask the Arborist

The key to controlling many types of insect and disease issues is targeting the problem before it starts.  For instance, we have talked about  emerald ash borer.  By the time trees show signs of infestation, significant damage has already been done and you are fighting an uphill battle to save the tree.  However, there is strong evidence that indicates that disease is less severe in trees that have received preventive treatments.

We are currently applying our preventive insecticide treatment. This is a systemic injection that offers year long protection against most destructive pests. Injection occurs in the spring prior to the start of insect activity, protecting your trees from the following:


*Aphids *Japanese Beetles
*Leafminers *Flat head borers including Emerald Ash Borer (EAB)
*Elm Leaf Beetles *Soft Scale Insects
*Lacebugs *Tent Caterpillars
*Bagworms *Zimmerman Pine Moth

 

Coming up in late summer/early fall, our preventive fungicide treatment offers the same year long protection against Nebraska’s most common tree diseases such as:

 

*Anthracnose *Rust
*Rust Disease *Crabapple Leaf Disease
*Powdery Mildew *Ash Gall
*Flower Blight *Diplodia Tip Blight

Ask the Arborist - Are my trees out of the woods with recent rain?

Posted by Lacey Martinez on Mon, May 20, 2013 @ 05:15 AM

If your tree’s leaves are starting to appear, you may think that the tree is in the clear as far asClump River Birch drought damage goes.  However, during periods of severe drought, a tree may lose a significant portion of the root system because roots cannot live in soil that is dry for long periods of time.  Also, the tree has used a good deal of energy and its reserves trying to keep itself cool in the hot temps and dealing with reduced water uptake.  The tree will also have a difficult time fighting off insects and disease.  So, how do trees recover from severe drought conditions?

 

WATER! Proper tree care requires that you monitor the soil moisture.  Use a garden trowel or a screwdriver to check the soil moisture 2” below the surface.  If it is dry, then it is time to water.  Sometimes a lawn irrigation system will not water deep enough to reach the tree roots.  You may need to pull out the hose to soak the soil.  You want the soil to be moist but not soggy.

Maintain 1-3” of mulch around the base of the tree, but avoid mounding it against the trunk of the tree.  Mulch protects the trunk from mower and string trimmer damage, maintains soil moisture and adds nutrients to the soil as it decomposes.

Monitor the tree for any signs of insect or disease problems.   By catching the problem early and correcting it, you can help the tree fight off the problems it may not be able to handle on its own. Click the buttom below if you would like a licensed arborist to inspect your trees.

Ask The Arborist - How often should I prune my trees?

Posted by Rachael Monico on Thu, Apr 04, 2013 @ 03:37 AM

Ask The ArboristFor a new tree, the only tree pruning that should be done the first year would be to remove any dead, damaged, or diseased branches. After the tree has been planted in the ground for one year, you can begin to prune the tree to improve structure and aesthetics. This may need to be done each year until the tree has a strong, balanced structure. Training young trees optimizes structural stability in the mature tree.  By pruning a tree when it is young, you can avoid problems such as co-dominant stems, weak branch attachments, and crossing branches. This can greatly reduce the maintenance costs associated with correcting these structural defects in the future.


Norway Maple

For a mature tree, how often you need to prune will depend on the history of the tree. If it has been well maintained through the years, the only pruning that may need to be done would be to remove any dead, damaged, or diseased limbs. If the tree was not properly trained when it was young, it may have problems such as splitting branch attachments, branches that are too low, or other structural defects.  Typically, removing more than 25% of a tree’s leaf area during one growing season should be avoided. The tree may need to be pruned once every few years until it has good structure and aesthetics.

 As always, we recommend consulting a licensed arborist before pruning.

Emerald Ash Borer Creeping Closer!

Posted by Rachael Monico on Mon, Oct 15, 2012 @ 11:55 AM


Emerald Ash Borer
The Emerald Ash Borer (EAB) is an invasive insect that has destroyed tens of millions of ash trees in North America and Canada since 2002 when it was first discovered in Michigan. The beetle is native to Asia and was brought to the US by infested wooden pallets. It attacks all ash trees, regardless of age or health. Trees become infested when adult beetles lay eggs on the bark. The eggs hatch into larvae that bore into the tree. They tunnel just below the bark and disrupt water and nutrient movement, eventually killing the tree.

 

Until recently, the closest the pest had been to the Omaha area was in extreme north east Iowa in Allamakee County. On July 20 of this year EAB was discovered in the Kansas City area and on Aug 29 it was discovered in Wyandotte County in Kansas. The borer is usually spread by moving infested firewood to campsites around the country.

The recommendation that the Nebraska Forest Service is using for when to begin preventative EAB treatments, which other states are using too, is not to begin treatments until you know EAB is within 15 miles of your location. We will continue to keep you up to date on the latest EAB news. There are several chemical treatment options that have proven to be effective in protecting ash trees from the devastation of EAB. While it is not impossible to save an ash tree once it has started to show signs and symptoms of an EAB infestation, the success rate of keeping an ash tree alive is much greater with preventative treatments. Symptoms can be difficult to recognize because many of them look very similar to the effects of drought stress on trees.

Some signs and symptoms of infested trees include:
  • Thinning canopy

  • Branch dieback from the top of tree

  • Delayed leaf out in the spring

  • Woodpecker damage

  • Epicormic shoots/water sprouts

  • Bark splitting

  • D shaped exit holes

  • S shaped tunneling under the bark

If the thought of losing your ash tree concerns you and confirmed sightings within 15 miles is too close for comfort, contact us and we will have a professional arborist take a closer look. We can answer any questions you may have regarding appropriate preventative treatment measures.
