Thanks! I did go through and picked all the infected fruit I could see/ reach right after I found out what it was. Then I got mostly good berries. I thought the picking had made a difference but maybe that’s just how it goes naturally.
We got the first tree seemingly out of nowhere. It grew on its own between a pine and an elm. I thought it was a weed and tried to pull it, but it was already two big so I just cut it at the base but it kept growing and getting stronger. So eventually I gave up and let it grow. Now it’s a beauty and full of berries.
We live next to a wooded area and recently noticed older mulberries in the walking trails. That’s where it must have come from. Since then we’ve noticed two more young ones in our yard. We’ll let them grow. We’ve also planted a peach last year that have me 4 preaches this year and a mandarin orange we planned recently and are struggling to keep alive.
