I don't have a ridiculous amount of dandelions in my yard, but bending over that many times to uproot them about killed me. Trimming back the hedges, weeding, raking all the mess up, and getting the yard generally ready for summer was murder on my back. I'm going to put weed'n'feed stuff down on Monday and do my first full mow of the season.
But, the back breaking work is more or less done, since this is the first year we'll have a riding mower.
