The Good News About This Freeze Damage is that it is only temporary.
If your plants were healthy, strong, and vigorous they should leaf out again in about 2 weeks. So continue to keep the soil around them moist but not wet. Over-watering these freeze damaged plants could result in further damage and even death.
The Bad News About This Freeze was that damage to young developing fruits is irreversible.
This was looking like a great year for fruit production on area trees. The favorable temperatures of the last 30 days resulted in heavy fruit set. The exposure to the freezing temperatures of the last few mornings has damaged the developing fruits. Within hours these young fruits may become discolored
and fall to the ground. Some damaged fruits like those of Peaches, Pears, and Apples may take several days to notice. However, if gently squeeze a damaged pear, peach or apple fruit they will not be firm but will feel soft. A soft fruit is a symptom of freeze injury.
Normally fruit trees only bloom once so so much for this years production. It is interesting that the freezing temperatures do not injure the young leaves but only fruits and flowers.
