Water Wise Landscaping

Water wise landscaping means landscaping with water conservation as a major objective. You may have also heard this referred to as “xeriscaping.”

Whether you are designing and installing a new landscape or retrofitting an existing yard, there is a lot to consider.

CSU Extension has lots of resources on water wise landscaping:

Insects and Disease Issues of Ash in the Tri River Area

For many years, green, white and European ash were planted heavily in the Tri River Area for their fall color and because they were thought to use less water. It turns out they do not thrive in hot areas like parking lots and rocked landscapes. Even prior to the long-term drought, these trees attracted lilac ash borer. Ash trees, Fraxinus spp., make up more than 20% of our tree canopy, providing shade, oxygen, and many more benefits. If your ash tree is young, small, or if more than 30% of the canopy has died, consider planting a different tree species nearby to eventually replace the ash tree. This is called planting a shadow tree.

Ips beetle affecting Western Slope Pinion Pines

The prolonged droughts of 2016-2018, have caused great stress to our native Pinyon Pine trees.  This stress has allowed the Ips confusus beetle to take advantage by boring into the trunks of the trees and eating the cambium layer resulting in death of the trees.

Colorado Woody Plant App is Available on All Platforms

Coloradans now have an app to help identify trees, shrubs and woody plants – CSU Extension announces the launch of the new “CO Woody Plant” mobile app, available for free on iOS, Android and Google Play!

‪Identify 200+ species. The ‘plant characteristics’ screen uses visual icons to guide the user through a series of choices to narrow down the possible plants. It also offers the ability to search in ‘offline’ locations without a cellular connection. Check it out at your favorite app store.

Plant Diagnostics

Plant Problems? Bring us a fresh sample!

  • Master Gardener diagnosticians are meeting each week in each of our offices, to examine the plant samples that have been brought to us and try to determine the cause of the problems. If you are bringing us a plant sample, there are several things you can do to help out the diagnostic team:
    • Bring in as fresh a sample as possible. Plants left in a hot car become much harder to identify.
    • Bring in as much of the plant as possible, including the root where feasible. Bring along
      Tomatoes with Blossom End Rot

      some of the soil, so it can be tested for salts.

    • Bring in both an area of the plant that is suffering, and if possible an adjacent section that is doing well. This is especially helpful with turf samples.
    • If you need the plant identified, flowers and/or fruit will make diagnosis easier.
  • When you come to the office, the Master Gardeners will have you fill out a form that asks a number of questions about the plant. Answering these as thoroughly as possible is very helpful! You can reach the Master Gardeners at each of our offices. In Delta, we’re at 874-2195; in Montrose, at 249-3935, and in Grand Junction we’re at 244-1836. Leave a message and we’ll get back to you as soon as possible.
