Late 2017鈥檚 snow and ice was an inconvenience for just about everyone in Chilliwack, but for berry growers, and fruit and ornamental tree farmers, it could be costly.
Over a 48-hour period, two freezing rain events led to a total of 27.4 millimetres (mm) of ice accretion, according to Roger Pannett, Chilliwack鈥檚 volunteer weather observer for Environment Canada.
That鈥檚 even more than the severe ice event overnight Feb. 8 last year (25.6 mm) that led to severe tree damage, even greenhouse collapses.

University of the Fraser Valley agriculture professor Tom Baumann said the early winter weather can鈥檛 be good for farmers, although so far he has had no reports of serious damage.
鈥淚 collected the 鈥榖efore winter鈥� samples on the day before the ice and snow happened, so in March I go out again to sample and I can tell how much fruit we lost over winter,鈥� Baumann said.
Even this measurement won鈥檛 take into account what happens after that, such as spring frosts and heavy rains.
鈥淎lso, we can鈥檛 really access fields well right now, even for pruning, so those still needing pruning will have to wait until this all dissolves into a mess again,鈥� he said.
By mid-week blueberry crops, as well as all trees in the Fraser Valley, including fruit trees, cedar hedges, and other ornamentals were covered in a layer of ice. The melt did begin Wednesday, which is the good news, according to Baumann.
The lack of wind is another bit of good news as that could have caused serious damage to branches coated in ice.
鈥淲e did not get the promised strong outflow winds, again, another very positive thing, especially for raspberries,鈥� Baumann said. 鈥淭he strawberries were nicely tucked under that first snow fall, so I am hoping they were completely unscathed.鈥�
Hobby farmers and backyard gardeners may have already noticed some breakage due to ice accretion but Baumann doesn鈥檛 recommend shaking or hitting the branches until the ice melts off naturally.
鈥淭hen repair, prune, stake or do whatever seems right to do,鈥� he said.
With rain in the forecast, there could be more bad news for perennials with 鈥渢ons of water sitting on our fields,鈥� something that can stifle growth as the roots need oxygen.
鈥淟ooking around my own property, I see far less damage than in 2016/17 ice storms,鈥� Baumann said. 鈥淟et鈥檚 hope this was the last one for this winter.鈥�
