Emerald Evergreen's Dying?

Asked January 28, 2014, 3:03 PM EST

I planted more than 27 varieties of evergreen trees in my yard to help with noise reduction. My emerald's were doing beautifully, but now I'm afraid there is very little green left on them. Will they pull out of it or should I take them out and replace with a more drought tolerant evergreen? Thanks so much for you time in this matter.

Junipers and arborvitae really "burned" from last April's temperature plunge. Needles dehardened from weeks of mild spring temperatures and got "zapped" when April 9 temperatures dipped into single digits. Your trees' current damage may be a result of this.
Many of the affected junipers and arborvitaes will show new growth later this May and June, depending on whether they were in wide-open windswept areas or in protected spots.

It is important for the health of your trees and shrubs to winter-water during times without snow on the ground - not now as we are receiving some snow. To learn more about winter watering, check out this link:

Should you replace your Emerald Evergreens?
You certainly can. There are evergreens recommended for Colorado, which will give you more success. Also, it is a good idea to plant a variety or trees or shrubs. Selecting 1 type of tree results in all being affected by a growing condition like the freakish weather we experienced last spring. In this link, scroll down to page 8, where the evergreen selections begin:

Finally, if you do decide to replant, it is very important to plant correctly. This link has great information on planting shrubs and trees.

I know this is a lot of information, but winter is a great time to read in preparation for warmer weather when we can enjoy gardening!
