Happy Labor Day!
Where did the summer go?  School has started, the daylight hours are getting shorter, nighttime temperatures are starting to cool down and that means, it's time to get ready for the upcoming fall season.  

Now would be a great time to have your trees deep root fertilized; after all, they have had a very stressful spring and summer. Our deep root fertilization lasts for up to 2 years and could make a large difference in the health of your trees.

If your lawn is looking a little peaked, or you just want to make sure that your lawn is in the best shape it can be going into the fall season, you may want to consider a fall lawn fertilization as well.  

With the last big holiday weekend for the summer coming up, Mountain High would like to wish you all a very safe and happy Labor Day Weekend!

Throughout the spring and summer we have watched the increase in fungal and bacterial diseases all across the Lilac Bacterial BlightDenver Metro Area. High incidences of Bacterial Leaf Scorch in Ash trees have caused significant leaf drop and branch dieback.  Fire Blight has infected Apple and Crabapple trees in every community without regard to age or variety.  Just this past week I visited a property with 4 lilac bushes all severely infected with Lilac Bacterial Blight.  Our Arborists have visited numerous properties to find foliar leaf spot disease in Maples, Cottonwoods, Plums, Apples, Crabapples, Aspen, and Roses. 
Many people have already noticed the early leaf drop as a result of fungal diseases like leaf spot.  This will continue through September and become even more pronounced as the nighttime temperatures drop.  These foliar infections have already gone through their life cycle and now will overwinter on the tissue they destroyed.  It is important to perform a thorough yard cleanup to help prevent new infections next spring.  The weather conditions of this spring and early summer were the major factor in the high occurrence of many leaf diseases.  Preventative fungicide applications during the infection period are helpful in protecting newly developing leaf tissue in the spring.  These applications need to be done during the entire infection period, or until new tissue has developed the waxy cuticle that provides a measure of natural protection.
The bacterial diseases are a bit more difficult to treat and prevent.  Most bacterial diseases like Fire Blight are prevalent in the environment, and are simply waiting to find a suitable pathway to enter a host.  This occurs frequently during springs that have multiple hail storms, causing branch and twig injuries.  These wounds are a perfect route of entry.  Once an infection occurs then a variety of treatments can be considered as part of a recovery program.  Properly timed pruning can reduce the amount of infection that overwinters in the vascular system of the trees.  Foliar treatments in spring with a fungicide/bactericide can limit new infections from starting.  Trunk injections of antibiotics can therapeutically reduce the internal spread of the disease.  It is important to meet with your Arborist when deciding what steps should be taken to help in the recovery of your trees.

Lee's Lawn Tips
I have seen several drought stressed lawns this month and cannot say it enough...watering is key to keeping your lawn healthy and fall is a key time to prepare your lawn for winter. It is also the time when watering is most often neglected.

foot prints indicating dry turfIgnoring fall watering will open your lawn up to insects and diseases. Proper watering should take into consideration the species, soil type, fully shaded area, full sun areas and weather conditions.  A sure sign that your lawn is dry is when you leave footprints on your lawn that do not disappear within 1 hour.

We are also recommending a fall lawn fertilization to prepare your lawn for winter.


Voles have continued to be a problem this year, which is unusual during the summer months. Voles are small mammals, slightly larger than a mouse, that normally live in field and shrub habitats. In the wild, voles forage on native vegetation and provide a valuable food source for predators such as weasels, owls, hawks, and snakes. In homeowner plantings however, (includes lawns, flowers, shrubs, and home orchards) voles can cause serious damage by eating flower bulbs, girdling the stems of woody plants, and gnawing roots. Plants not killed outright may be invaded by diseases or die from water stress during periods of drought.

As the summer season is winding down, most of us have either forgotten or lost track of our irrigation systems. Water management this time of year could still save you a considerable amount on your water bill. Simply monitoring the weather and reducing the times on your irrigation controller or even eliminating a day a week will make a significant difference.There are other little things that you can do to your system to make it more efficient that may involve a bit more work. The installation of a rain / freeze sensor will suspend the watering of the irrigation system if the weather dictates. These are now wireless, making the installation a breeze. There are also soil sensors that can be installed in the ground which can suspend watering if the soil moisture reaches a predetermined amount. Internet based and on site weather monitoring devices can be added to most modern irrigation systems with little effort and can produce a dramatic change in your usage.

Pine Wilt Disease found in Scotch, Austrian and Mugo Pines


As summer wanes, dead Scotch Pines have been appearing with more frequency in communities along the Front Range of Colorado. The culprit has been found to be the Pinewood nematode, a native to North America.  It does not generally cause death in native Pines, but in exotic Pines it causes a fatal wilt disease.  It can be deadly to the Scotch, Austrian and Mugo Pines planted in our landscapes.

The Pine wilt nematode is transmitted by Pine sawyers or long horned beetles, a group of native wood borers. Infection of Pines by the nematode starts in June or July, but symptoms don’t usually appear until late summer.  The tree wilts and browns quickly due to the inability
Pine Sawyer beetles
of the vascular system to take up water due to the multiplication and feeding of the nematodes.  On Scotch Pines, the entire tree usually browns quickly whereas on Austrian Pines it may be restricted to a portion of the tree.  Diseased wood becomes very dry and brittle and blue stain fungi will be present. Dead needles will often stay attached to the tree through the winter. 

Removal of infected trees before May of the following year is important, before the re-emergence of the Pine sawyers. If other trees nearby are at risk there are a couple of injectable compounds that are recommended for protection from the nematode.
If you are concerned about your Scotch, Austrian or Mugo Pine trees,
please call our Colorado Springs Office at 719-444-8800.

I hail from the Las Cruces, New Mexico area. I have been known to say that I am related to half the town! Our family is a blended family of 5 ‘kids’ that range in ages from 35 to the youngest being 27. We have a 10 yr old granddaughter and a 3 yr. old grandson. I share my home with my wonderful husband Terry and my 2 cats, Smokey and Lucky. My most favorite place to be is in my backyard on a summer evening.

Thank you everyone at Mountain High for making me feel welcome!

We are lucky to have Patricia, she is quick to learn and just an all around great person to work with.  Welcome to our team Patricia!
