Thanks.
Yeah, I figured they wouldn’t be very tasty and would need further treatment.
But would sure make my neighbors go... “WTF?”!
Interesting thing I also never knew is that the tasty Damson Plums are very cold hardy. I’ve just grown the American plum here which comes through every year. But is only good for jelly and jams.
According to the Gardening article they make marmalade good fencing. (A thorny hedge!)
