The so-called Polar Vortex that just exited the Region will likely have an effect this year's fruit crops in Indiana, says Lake County Purdue Extension Educator Nikky Witkowski, who spoke to our Jay Stevens. Most apple and pear trees in the Region are able to endure a zone five winter even with this season's below zero temperatures, but Witkowski says peach trees are less tolerant. There are also differences between the different varieties. Witkowski also says the majority of the Region's blackberry and blueberry plants should be okay as the ample snow cover can actually insulate plants from the cold temperatures. Witkowski also says there are steps that can be taken once the warmer weather arrives. To hear the interview visit News Audio on Demand here at our website.
