My mulberry tree is done. Heck of a crop this year though. I stopped and ate a few every time I came up our driveway.
What's interesting is that when we had the big flood three years ago, that tree was producing at that time. I've deleted the pics from my album but I was riding down there and fishing on our road. The fish were feasting on those mulberries as they dropped from the limbs.
Try some for bait on the river and see if it works.
The river feeding Tbird I fished many times and caught catfish on worms , shad, shrimp and liver.
One day they would not take anything.
Mulberry tree was dropping berries into the river (creek) and catfish would eat them as soon as they hit the water.
I tied on a gold crappie hook and wormed a mulberry onto the hook and tossed it in under the tree.
