those are PERFECT for a great compost (the best fertilizer ever just email me to learn how to do it) or you could cut them up and put them in a cloth sack, ad water, and leave in somewhere to rot, once it ferments with a musty smell, with gloves press down to make a 'tea' and add orange oil and add 1/4 'tea' to 3/4 water to water your plants...it makes a great fertilizer...i've never heard of a grass clipper picker upper....hmm...i guess it's cause i live in the country....
GOOD LUCK! = P
