We have a tall (Really tall) mulberry tree in our front yard. Most of the tree is completely beyond reach and provides food for the birds and racoons (until the coon hunters come around) How I've been harvesting them is laying a tarp on the ground and taking a broom handle and wacking the branches until the ripe berries stop falling. Then I pick the berries up from the tarp. There are so many berries that I'll never be able to harvest though. I'm not climbing into a 30 foot tree to go berry picking. Today I've got the berries sitting in sugar for supper. I'm hoping to make a batch of mulberry jam, though I'm not sure I'll get enough at one harvest for that. I can only get berries off of about 6 branches.
