Trees flower in spring. If spring temperatures fluctuate widely, the cherry may heat up enough for the flowers to start just to be killed by a late freeze. When water in the cells freezes, rupturing cells, damage occurs. This does not occur when the temperature briefly dips below 32 degrees Fahrenheit. The temperature has to fall to approximately 27 degrees for an hour or two to occur. Delaying blossom is more effective than warming the tree at preventing damage.
Plant cherry trees onto a mountain when at all possible. Seek websites that are from sunlight in winter to maintain the tree out of warming up, but are not in frost pockets or even air drainage websites. Select tree types that flower or are less vulnerable to frost damage such as Norman or Redhaven.
As trees low in nitrogen are more likely to flower early, fertilize the tree after harvest and have less resistance to pressure. Apply 1 pound of nitrogen per 1,000 square feet of area.
Mow the plantings beneath the tree to a height of 2 inches or less. Firm soil keeps and radiates the warmth on chilly nights.
After whenever the temperature is above 45 degrees Fahrenheit to cool the buds, the buds start to swell irrigate the orchard with sprinklers and delay flowering.
Cover the tree with a blanket or floating row covers if sub-freezing temperatures are predicted and place incandescent light bulbs in the canopy, or series traditional Christmas tree lights (the large bulbs that get warm when they’re lit) in the tree.
