I've got a macadamia tree in the front yard. I've read that I shouldn't pick nuts from the tree, but instead wait for them to fall to ensure they're ripe. We harvested a lot of nuts that way for a year or two, but after squirrels discovered the tree, no intact nuts ever hit the ground. Just husks. We're willing to share with the squirrels, but it would be nice to get a few macadamias for ourselves. Does anyone have any experience harvesting macadamias directly from the tree?
