Extreme Temps
affect our Trees

It is obvious that the heat of summer has set in with no sign of relief any time soon. We all feel the effects of the heat: lack of energy, premature exhaustion, and an overwhelming desire to seek the coolness of the shade. The fact is that our trees are affected in the same manner by these extreme temperatures.

Trees respond to the heat in very predictable ways. When temperatures rise above normal, tree roots become inactive. The flow of water and nutrients stops in order to prevent the tree from drying out completely. Portions of the leaf canopy that are less efficient are shed in order to retain the more productive portions of the tree.

Trees cannot seek the shade so they must change how they do things in order to stay alive. We see these stresses and must be careful not to over-react. It is dangerous to over fertilize or over water, even though that is an all too common reaction.

Arborists are trained to recognize the changes in plants based on the symptoms they exhibit in the leaf color, growth patterns, canopy condition, and overall vigor. Knowing the local weather conditions and patterns and how that information relates to this area's plant species is vital in determining if changes are normal. Consult with your Arborist when you see things that you suspect are out of the ordinary.

    Heat Stress in Lawns  

Heat Stress in Lawns

Much like any other living organism, lawns can suffer symptoms of heat stress.

Heat Stress is caused by high heat and lack of rainfall. This can particularly be a problem in the Colorado environment because of our typically dry summers and lack of humidity. Watering consistently is one of the most important maintenance practices in taking care of your lawn. However, even adequate water is not always enough. Temperatures of well over ninety degrees day after day causes a slowdown in grass growth. With low humidity, the blades of grass can experience a daytime wilt which can cause a loss of color normally associated with a healthy lawn. This does not mean the lawn is dying or in serious trouble.

Eighty percent of a grass plant is comprised of water. High heat and low humidity takes some of this away, even with good watering practices. Lawns that are getting properly watered now will recover much more quickly than a drought stressed yard will when the longer nights and cooler days return.

Water at least 2 to 2 1/2 inches per week. One inch of water should re-wet the soil about 6 inches deep. To determine how much water has been applied, set a straight-sided can under the sprinkler.

Of course, without adequate water, heat stress quickly turns into drought stress.

In a drought stressed lawn, grass soon turns brown and becomes dormant. An early clue to drought stress is when grassy areas show a dark bluish-green cast. Begin applying water when the soil starts to dry out and before the grass wilts and has a chance to become brown.

A word of caution about limited watering:
A single watering during a high heat and/or drought period is likely to do more harm than good. If the grass cannot be kept actively growing with sufficient water, it is best to let the grass go dormant. Inconsistent or "light" watering during extended dry periods will slow the rate of recovery when adequate rainfall does occur. Bluegrass is very resilient and will come out of the heat and drought quickly as long as it is properly cared for and steps are taken to keep insects and weeds out of the stressed or dormant areas of the lawn.

Some things you can do when water restrictions prevent you from watering as much as the lawn really needs:

  1. Water only that part of the lawn where improvement is most important.
  2. Water only in the early morning.
  3. Use a sharp mower blade; the cleaner the cut the less water the grass blades will lose out of the injury done by the cutting.
  4. Mow regularly until growth slows, but at a higher (rather than lower) cutting height.
  5. Make each watering consistent and make sure enough water is being applied to moisten soil to a good depth. Remember, with humidity as low as Colorado's tends to be, a ten minute watering of most sprinkler systems will not likely get enough water into the soil. This will force the roots to go shallow and weaken the lawn's resistance to heat stress and drought stress/damage.


Japanese Rock Garden Project in Aurora

Our objective for this project in Aurora was to provide the homeowner with a secluded area of the yard to sit and relax in the evening and enjoy the calming sound of a water feature. Our customer had spent time in Japan and wanted the space designed to mimic a Japanese Rock Garden. We focused mainly on the rock and water elements but also included some dwarf evergreens and Japanese Maple trees to soften the hard lines of the boulders. We also installed a flagstone patio in keeping with the theme of natural elements.

The project itself was installed over a 4 week period in which we removed several volunteer shrubs and trees, re-graded the area, installed approximately 40 yards of topsoil, as well as roughly 25 tons of moss rock boulders. The water feature stands about 5 feet high with a small pool at the top for the water to collect in before making its way down three separate waterfalls and 30 feet of stream. Our customer did not want the added maintenance issue of a pond, so the water feature was designed to be pond-less. The patio is roughly 120 square feet of red flagstone with a random stepping stone path connecting this seating area to the main patio. We will soon install the finishing touches of the project; a low-voltage lighting system to accent the waterfalls and some of the specimen plants. Let us know if you would like to have one of our Design/Build experts visit with you on any of your dream projects.

from Craig Little
Craig LittleTip of the Month:

Take a hint from the overwhelming heat of the past two years and plant "drought tolerant" and "drought resistant" plants. When getting ready to plan your next landscape project, it may be wise to consider all the advantages of using plants that not only live in the desert-like conditions of the Front Range, but can actually thrive without further burdening your water resources.
