Oozing nectarine tree
It is mid-January here in Elgin, SE AZ, elevation 5,000. feet. We have been having freezing weather since early December. Our nectarine tree is 5 or 6 years old. Yesterday, while pruning, we noticed copious amounts of a clear jelly-like substance oozing from many places on the trunk and from a few branch crotches. Help!
