Just sharing a mulberry I've had for a few years. Collected as a sapling. Spent some time in the ground then a pond basket. Repotted early this spring and pruned/shaped yesterday. I found a better front unfortunately after the repot. Live and learn.
This one has not fruited. I found it in my yard as a sapling in 2019. It only spent a little over one year in the ground. I should have let it 'cook' longer but it was my first one. Now I always snatch them when I spot new ones popping up and I have a few bulking up in ground. You have to stay in to of them because they grow fast lol.
