WHY CHERRY ORCHARD TREES HAVE WHITEWASHED TRUNKS


CHERRY TREES WITH WHITEWASHED TRUNKS  (sunny day)

DITTO (cloudy day)
Monday, 9:00 AM.  39 degrees F at the ferry dock and on the back porch (quite unusual for both to have the same reading).  Wind variable and calm, the sky overcast, with heavy fog over the channel.  The humidity is 95%, the barometer 29.64" and falling.  The weather for the coming week is forecast to become much colder, lows dropping into the teens and lower, with highs in the twenties.  There is a chance of rain today and snow tomorrow, with wintry weather thereafter. 
   Cherry tree trunks have thin bark, susceptible to sunscald damage. The above photo shows sweet cherry trees with white-washed trunks  White reflects the sun's rays. This is a good way to prevent sun damage in late winter, when  strengthening sunlight reflects off the snow and can damage the bark. 
   Bayfield is a far northern location, but the cold is modified by Lake Superior, so sweet cherries can be grown here.  Lapin and Cavalier cultivars grow well and are as good in flavor and appearance as any. Sweet herries bloom early and are susceptible to frost damage and also failure of insect pollination, so not every year is a financial success, but averaged out, the crops are a great cash crop for those orchards that choose to grow them along with apples.
