The long, cold winter has resulted in a strange phenomenon — sunburned trees.

As a result, many of Winnipeg's evergreen trees have brown needles.

Mike Allen, owner of Viburnum Tree Experts, said the frozen ground means there's not enough moisture at the tree roots to replace what has been lost at the top.

"Microscopic moisture cannot replace all that dehydrated heat that's coming off of the needles and then it starts to go into stress," he said.

The best way to prevent tree sunburn is to water your evergreens well in the fall, he said, adding that trees exhibiting the brown needles should be able to heal themselves as the ground thaws.
