In this photo, I am explaining to the participants, highlights of Lasagna Gardening.

In the following photos are a variety of material being used.

(left) Garden refuse which I have already put at the bottom of our pile.
(right) We will put in different kinds of manure. Chicken, Cow, worm casing.
(Do not use dog or cat manure, these are not healthily).

(left) Straw - hay may be used, but hay will contain more weed seeds than straw.
(right) Barn refuse.

(left) Peat moss. (right) Old Compost.
     

 (left) Kitchen scraps or grocery produce waste.
(center) And leaves...I use lots of leaves...Because they are easily available.
(right) I built a box about knee high only to contain the material. You do not have to build one.
You can make your pile with open sides right on the ground. If space is an issue,
 I suggest building the box. when complete your pile will be between 18" - 24" high.

 We'll start with the garden refuse of the week. Twigs, etc. At the bottom with some lime to help breakdown this stuff.
some people like to use lime and some do not. I use it to break things down and to neutralize acidic items.
 Its is a personal choice to use or not.

(left) Now we're putting down a layer of leaves. (If you have oak leaves add a little bit of lime,
 since oak leaves are acidic. (right) Adding a layer of peat moss.

(left) Adding a layer of barn refuse. (center) Adding a layer of straw.
(right) Add peat moss frequently throughout the pile. You want to water periodically, just wet it well, but do not over water.

 Keep repeating your layers till you have used up all of your collected materials.

(left) Periodically you can add garden food, but especially towards the top.
I use a 5-10-5 or something similar. (right) Keep watering.

(left) Your very top layer should be decompose compost or top soil, or any good growing medium about 6" deep.
(right) One of the beauties of this method is that you can plant in it the same day you put your lasagna bed together.
Here we planted some tomatoes plants, but you can also plant seeds.

Water.

As time goes by your seeds and plants will grow to maturity and your lasagna mixture will be decomposing
 down into a delicious compost for future use. This is truly a double duty method. You grow it, then use it.

TIPS:          - Each layer should be between 4" - 6", peat moss may be less.
                  - Be looking for materials all year long.
                  - Collect leaves in the fall.
                  - Collect straw at Halloween, or at stables.
                  - Kitchen scraps can come from your own kitchen or talk to the produce man at your local grocery store.   
                    (You can collect bags and bags of this stuff at your grocery).
                  - Do not turn your pile. You are making a "LASAGNA" garden.
