If you are looking to create your lasagna bed quickly ask your neighbors for their fall leaves and/ or grass clippings - I have never been turned down!
It is also recommended that you add a layer of bulky material such as twigs or branches to help aerate the pile. Our Christmas tree boughs were used in one of the front parking strips.
Ideally you would begin this process in the fall, but if you begin sooner just help the process by "watering" the bed until mother nature takes over. All of our beds were then covered with 3 or more inches of microbial mulch to give them a finished look.
If you are planning to plant directly into the bed before the material has fully broken down, as we did with some transplants, use potting compost around the plant to ensure proper root development. The lasagna bed will take 6 - 9 months to fully break down depending on the materials you use and diligence in layering and keeping it moist.This photo shows a bed with some postting compost around transplants, and chipped material from when we had the tree in the backyard pruned.
All composting requires four basic ingredients:
Browns—Includes materials such as dead leaves, branches , twigs
Greens—Includes materials such as grass clippings, vegetable waste, fruit scraps, and coffee grounds
Water & Air
