Since we have experienced winter lows of minus 8 and minus 6 degrees Fahrenheit in January, we assessed winter bud injury for some cultivars. As part of his VESTA practicum work, Jeremy Emery is managing the assessment. Jeremy, Randy Stout and Asher Ramsey have all learned the assessment process and evaluated the % primary bud mortality for the following cultivars.
|Cultivar||% primary bud mortality*|
* Based on number of dead primary buds in a 100 bud representative sample.
