Hello TTT members:

What a great time of year to be in Colorado. One never knows what to expect with our weather - winter conditions one day - then sunny the next. Our trees face this same challenge of adapting to the weather. Remember: New trees need your TLC. Wrap the trunks on young trees and also you need to shade them from southwest sun damage. If conditions are dry, some extra watering may be necessary.

Fall Pruning

There are several reasons to use fall as the ideal time to prune your trees. Preventing storm damage, removing diseased material, and preventing the overwintering of fungi and bacteria are just a few.

1. Prevent storm damage

  • Abundant growth during the season leaves branches long and heavy
  • Heavy branches often break under the weight of heavy snows and ice

2. Sanitation pruning

  • Many diseases are less active or completely dormant in fall and winter
  • Pruning during the dormant season helps to decrease the spread of disease

3. Prevent overwintering of fungi and bacteria

  • Many pathogens remain in the environment by overwintering in or on fallen leaves and branches
  • Removing leaves and fallen branches allows new tissue in the spring to thrive without the pressure from disease

Some tree species are naturally predisposed to attack by insects or diseases. Pruning in the fall allows the tree a head start on recovering when the damaging agent is less active.

Fall Needle Cast

Almost as sure as the seasons themselves, we begin to receive an influx of calls this time of year from clients expressing dire concern about their needle-bearing trees. The notes that come across my desk often include, “is there something wrong with the Pine trees”, “my tree has that notorious Pine Beetle”, and “my tree is dying, come right away!” The answer is there is nothing wrong with your tree, it’s not the beetle, and it’s not dying. What we are seeing throughout the spruce, pines, and firs all over Colorado is a natural process of shedding the older, less efficient needle tissue.

Each tree has a slightly different schedule for conducting the physiological processes that are responsible for the eventual dropping of the needles. The major difference between normal needle drop and a stress induced action is the portion of the tree that is shed. The tree should shed needle tissue produced in the same year, and it should not affect any of the other year’s growth. The dropping needles should be clean from small fruiting structures or discolored banding that would indicate the presence of a fungal pathogen.

If you are unsure of what is happening to your trees, please don’t hesitate to call us at Mt. High. Tree disorders are easier to treat during the initial stages of symptoms, so early diagnosis is the key to any potential recovery.

Voles have become an increasingly destructive pest in many landscapes over the past few years. During winters of below average snowfall they spend most of their time hidden underneath various shrubs such as junipers and cotoneaster.

  Vole Damage  

Conversely, abundant snowfalls provide protection for voles as they feed throughout turf areas without the danger from predatory animals. The vole populations have also increased in recent years with the over control of predatory animals such as coyotes and foxes. The reduction of predatory bird habitat has also allowed vole populations to thrive as the hawk and owl populations dwindle.

It is very important to monitor the environmental conditions throughout the winter in order to stay ahead of damaging pests such as voles. Populations of many pests are responsive to environmental factors. Even the fecundity (reproductive tendencies of females) of many animals can react quickly when resources are abundant, and populations can increase exponentially in a very short time. It is essential to be aware of the potential problems in your landscape in order to stay ahead of issues.
