Effects of Tucson freeze linger

Posted: Updated:

TUCSON, Ariz. -- Six months ago, Tucson saw something that rarely happens, three straight days of freezing temperatures.

The cold snap killed trees and plants at homes and businesses in town.

The sites of the frozen February are still fresh in the minds of the workers at the University of Arizona.

"It was devastating.  I mean it it as its unprecedented some of the numbers went back to records that were set 100 years ago.  It didn't look anything like it is today as we walk around the campus," said U of A crew chief Woodford Remencus.

Crews had to cut down more than 70 trees around the university.  The biggest losses were the trees that had been planted on campus many years ago.

"Some were planted by Warren Jones in the early days of the campus and some go as far back as the 50's the 30's, the loss is significant as far as old mature trees," said Remencus.

Some trees that were thought to be dead have grown back.  But there are still empty spaces to fill and it could be costly.

"The arboretum depends on benefactors and we do replace trees as necessary," said Remencus.

On the north-west side of town, the McMahon's backyard had some dead plants, but now things are looking much better.

"Most of the damage was done you know in the first week of February and most of these plants either made it through the freeze without any problem or recovered real nicely," said Phil Seader.

Phil Seader with Green Things Nursery says people should have known by June 1 if plants or trees were going to survive.

"All these plants that are still alive have come back.  If they still look like they're dead, then they're dead.  They're not waiting around for anything to happen, a long time ago they were dead," said Seader.

A lot of people's citrus trees were affected by the freeze.  Seader says, if you cut them back they should survive.
