If you like to add compost to your garden and if you have a garden you really should add compost to it. Leaves are a good thing to add to your compost, after all the trees spends the whole spring and summer pulling nutrients from the ground. Why not take those leaves and compost them to add those nutrients to your garden. Old world garden farms gives step by step instruction for collecting and composting leaves. Give it a try, if you have trees you probably have to rake any way and if you put the leaves on the compost pile you can rake them onto a tarp and drag them there instead of wasting all those bags to throw them away.
