A friend of mine has a pretty large cherry tree and has suddenly started leaking sap. It's clear and abundant. Mostly in the crotches but one area on an upright branch. Also the leaves on the outer edge of the branches are shriveling. I dug up around the trunk and discovered a ton of large black ants and also some other flies hanging around. Any ideas or recommendations? He is kind of attached to the tree. Thanks.....
