Weather Stressed Plants

October 6th, 2010

We are having a beautiful stretch of weather in southeastern Wisconsin. The warm days and cool nights are great for the outdoor activities and projects we were denied most of the summer due to rain and mosquitoes! The crews at Wachtel Tree Science are happy to be out working in such great weather. I do not know about you but I feel like I have earned some nice weather to enjoy my yard.

The problem is, are your trees enjoying your yard? We have now gone weeks without rain and the soil is hard and dry. The fine roots of trees need moisture. This water is not only sent up to the top of the plant for all of the life processes that are carried on in the trunk and crown but is also needed for roots to thrive and grow. A mature tree can use a ton of water a day! Do your trees have that much water? Fall is one of the most important times of the year for root growth. If we have good roots, we will have a healthy tree.

One other critical factor in tree health is soil life. What is soil; it is not just a bunch of dirt particles? No, healthy soil is a complex community of living organisms along with the soil. A teaspoon of soil can have thousands of beneficial bacteria, fungi (called mycorrhizae), protozoa and other creatures. When the soil is dry, the systems that support these beneficial organisms shut down. Not having these beneficial organisms active can lead to tree problems and diseases. We are currently seeing an increase in root rot problems due to these stresses.

The best way to water trees is with a sprinkler to wet down a large soil area. Roots can extend out four to five times the height of the tree away. While it is not practical to water such a large area, getting the entire area under the crown and a little more will have you hitting a large percentage of the root zone. In the spring and summer you do not want to water the leaves or needles, because you can encourage diseases (this is not as critical in the fall). You can set a hose at the base of the tree but this tends to be very spotty. You would be better off setting a sprinkler low (to avoid hitting foliage) and moving it around to cover the needed area.

The rule of thumb is an inch of water every ten days from either you or Mother Nature. Your watering will not totally replace the rain we are not getting but it will help the plant get by. Then when it does rain, the soil will not be so dry that the rain just runs off. So while you are out enjoying the nice weather consider watering your trees and shrubs to help keep them out of stress. The benefits your trees give you make it well worth the investment of a little bit of time and water.

John Gall Village Forester

October 5th, 2010

Since the spring of 2008, Wachtel has been performing the duties of Village Forester for the Village of Fox Point.

John Gall is using his 20 years of municipal experience to work with the village four to six hours per week.

We are able to provide technical skills without the village having to hire a full-time person.

As a result, Fox Point can save money and still have years of experience at work.

John is using his skills to keep the street trees healthy and to protect the sensitive bluff areas running through the Village.

Mulching

September 24th, 2010

It is not to late to mulch. If your mulch is thin at the base of plants, top dress before winter. Mulch will insulate the roots, moderating temperature extremes; maintain soil moisture and control weeds next season. Long term as mulches biodegrade they add organic matter to the soil, building better soils. Proper mulching is one of the best things we can do for our trees. Keep mulch about two inches away from the trunks and stems, mulch the soil and root system – not the trunk!

Getting Ready for Winter

September 17th, 2010

This year’s lush growth is supporting a healthy vole population. Voles can completely girdle the stems of younger / smaller trees and shrubs. Begin setting mouse traps to reduce the population. Or set out poison baits. Put bait in some type of small container so that the baits are protected from the weather and only inviting to a vole. Set under shrubs and along your foundation.

Fall Tree Care Very Helpful after Summer’s Heat Stress

August 5th, 2010
Heat Stress
This has been a tough summer for trees. The extended periods of extreme heat that we have experienced this year have stressed some trees and made them more susceptible to problems.
High temperatures can have a detrimental effect on trees growing in tough sites or those with damaged vascular systems. Trees cool themselves through transpiration, a process where water is released from the leaves as water vapor. This is similar to the way we transpire water to cool our bodies when we sweat. As temperatures rise, water vapor is released through small pores in leaf surfaces. Even though trees have mechanisms to regulate water loss, water can evaporate from the leaves faster than it can be replaced. Even with sufficient soil moisture, trees and shrubs with limited/unhealthy root systems can struggle to move enough water. Lack of available water to trees and shrubs in hot areas often results in scorched, dead or wilted leaves.
Fall tree care will be very helpful this year. A great deal of root growth occurs in the fall. Practices that promote root development will go a long way to protecting their long-term health. Help your trees begin to recover as they head into winter. Call our office today to schedule a property tour.

Did You Know?

July 30th, 2010
  • Trees keep our air supply fresh by absorbing carbon dioxide and producing oxygen.
  • In one year, an acre of trees can absorb as much carbon as is produced by a car driven up to 8700 miles.
  • Trees provide shade and shelter, reducing yearly heating and cooling costs by 2.1 billion dollars.
  • Trees lower air temperature by evaporating water in their leaves.
  • The average tree in metropolitan area survives only about 8 years!
  • A tree does not reach its most productive stage of carbon storage for about 10 years.
  • Trees cut down noise pollution by acting as sound barriers.
  • Tree roots stabilize the soil and prevent erosion.
  • Trees improve water quality by slowing and filtering rain water as well as protecting aquifers and watersheds.
  • Trees provide protection from downward fall of rain, sleet, and hail as well as reduce storm run-off and the possibility of flooding,
  • Trees provide food and shelter for wildlife.
  • Trees located along streets act as a glare and reflection control.
  • The death of one 70-year old tree would return over three tons of carbon to the atmosphere.

    Investing In Tree Planting Pays Off

    July 23rd, 2010

    Homeowners and businesses investments in tree installations can reduce nearby noise 50% percent and site temperatures by as much as 9 degrees Fahrenheit, according to the U.S. Environmental Protection Agency and American Forests, a nonprofit conservation organization.

    99 out of 100 appraisers agree attractive landscaping increases the speed of home sales according to a survey conducted by the Society of Real Estate Appraisers.

    Viburnum borer

    July 19th, 2010

    Almost all types of viburnums have become susceptible to viburnum borer. This insect tunnels into the stems at, or slightly below ground level. Look for damage in this area. Stressed plants are more likely to become infested. Water properly to avoid drought stress and renewal prune if appropriate to keep plants vigorous.  Symptoms may be a curling and stunting of leaves and premature fall color, as well as dieback of some portions of the plant. Insecticide treatments require multiple applications are warranted only on high value plants.
