Cold damage check

0

For most parts of the country, spring has sprung and summer is just around the corner.  Many of your favorite plants were injured by the cold.  How do you know if these plants will survive?   Use a pocket or paring knife to scrape along the outer bark of the stems working your way back from the tips to the base of the trunk.  In some cases, it may be dark brown along the edges, keep working until you find a light green cambium layer; at this point, Mother Nature has made a decision for you.  Trim off  all dead plant material.
