Q.Looks Like Sap on My Peaches
I’m a novice at best. I have 2 peach trees as well as other fruit trees. My trees are four years old now and every year I get what looks like balls of sap on my peaches. I’ve tried picking it off and it leaves a spot on the peaches. Is there a spray/whatever to prevent this? I’ve been spraying the trees about twice a month with fruit trees spray but no help.
