You need to "shake" the bush to receive the walnut. Start in the center of the 4 flowerpetals, walk right for a few seconds, walk up until the scrolling stops, walk right, walk up a few seconds, now click around in the center of the weeds, you will receive the walnut. I just tested this method and it works flawlessly. Orientating with the fishing rod is also a great tip.
