sour cherry tree
I have a sour cherry tree that is about 4-5 years old and has produced great fruit, last year there was what looked like a white mildew low on the trunk - still fruited this year, but there were a lot of dead branches so I removed them. I have not seen the mildew this year. I do see what looks like a hardened sap (amber like) there are no signs of runnin sap on the trunk. Wondering if the hardened sap like substance is an issue I need to attend to, Thanks so much
