Jenny, I put whole leaves on my garden. Have to bring them in from outside source. I simply toss them in, but don't have a lot available. One year, I had a glut of leaves, and this is what I did: I placed them in a huge pile, and inoculated them with a high nitrogen fertilizer. I used urea, which is 46% nitrogen. As I piled the leaves, I shoveled a bit of soil on them, then topped off with some urea and saturated the pile with water. Or you can dissolve the urea/fertilizer in water, and soak the pile as you build it. Be careful, a little bit of urea goes a long way! I then covered with clear plastic to take advantage of what ever solar gain there was. This method produced some good break down by spring. Be sure to bury the edges of the plastic, and weight it down so the wind doesn't send it sailing. Then, you can disperse the pile, and depending on the break down, you can incorporate them into your beds several weeks before planting, use them to mulch around your plants once they are up, or simply use them in the paths between the rows/beds, The rain will still leach nutrients out of the surface leaves and down to the root zones.
