AILING WICHITA BLUE
El Paso County Colorado
Thank you for your question and picture.
There appears to be water around the base. Did you just water it? Do you keep it watered? If so how much and how often? Did you purchase the trees ( a few years ago) from the same place as the one in question? Are they the same variety? Do you have a copy of the tags?
The other 6 that I planted and are very pretty were purchased from a retail/wholesale nursery in Parker. They don't sell retail anymore. I wanted to go there to purchase the new 4 but out of luck. You can partly see them in the background of the one I am trying to survive!
Hope I answered all your questions so you might be able to help! If you need better picture, just let me know.
Are the yellowing parts crunchy and brittle or are they pliable? After a close inspection of the tree do you see any insects present? Any unusual lumps or bumps?
Once junipers are established they have a high tolerance of drought. Below is a link provided by Colorado State University that you may find interesting.
We don't recommend increasing the water. We need to make sure there isn't something else going on. Please take a look at this link from the University of Minnesota. Thanks again for your pictures and questions.
