Emerald Cedars Changed Color After Toronto Winter

Question

Hello,

I have 12 cedars in my garden that are 3-6 feet high in my front yard planted around as a barrier with 3 feet distance in between. This winter I had them covered using material from Lowes (not Burlap).

I removed the covers early spring and noticed some have turned light blue, others are partly blue and partly green and some are still green. Please let me know if I should be worried or whether the color will go back to green soon.

Answer 1

Many varieties of cedar are found throughout Northern North America. Cedar cultivars have foliage that ranges from solid green to bronze to bluish-tinged needles. Yellow or brown needles, regardless of species, indicate the tree suffers from environmental stress.
Some cedar species’ foliage turns blue or gold in winter as a response to frigid temperatures.
Regular watering will help insure the trees health, but only time will determine if the trees will recover into the previous green.
