I have a two year old nectarine tree which was very healthy - and I was looking forward to the first summer fruit - until the last month. A main branch coming off the truck has tree sap oozing out at a number of sites. It looks like the main truck has what MAY be the beginning of wounds in 4 or 5 places as well, but no sap. Other than that the new growth this year looks very good. DO I let the tree fight this on it's own? My garden is completely organic/no pesticides and I usually have no pest problems that get out of control. Thank you.
