I believe that we are going to see a lot of frost and cold damage to plants coming into clinic this spring. \u00a0Last week we had a hebe that had most of the outside leaves damaged while the inside leaves were OK.<\/p>\n

Remember that the cold weather that happened in November and December will now be showing up in plants. Right now and with all \u00a0the glorious sunshine, gardeners are starting to head outside and they will observe any damage for the first time.<\/p>\n
\u00a0It is time to brush up on winter cold damage to plants !<\/div>\n
\u00a0I have copied the pictures of winter injury from the article in the PNW . Please follow the link below to see the entire article.<\/p>\n

The winter of 2013-2014 killed<\/div>\n

of the plant.<\/div>\n
