I always hand weed, but it can be dangerous. I can't sit down or kneel down while I weed because I've run into a couple of yellowjacket nests in the ground this year and had to jump up and run for my life. Consequently, I bend over and down to pull one weed at a time and sometimes the wrong combination of twisting and bending throws my back out for a couple of days. Dangerous, as I said, but it has to be done.
