And I want to mention that although Lanza recommends "peat or other organic material", buying peat isn't necessary. Any organic matter can be used. You don't have to spend any money for lasagna, it's possible to scrounge enough free stuff. Use a mix of nitrogen materials ("green") and carbon ("brown"), and moisten lightly as you build the hump.

As you do your spring yard cleanup throw everything into the lasagna (fall leaves, flower stems, just leave out the Snicker wrappers and beer cans). On garbage night collect your neighbor's yard waste, too. You might get large loads of used coffee grounds at Starbucks. Scrounge. Anything organic can be used, google "compost ingredients"

Kimm often refers beginners to the Florida online composting site, and I think it's an excellent source. It's about compost, not specifically lasagna, but much applies, like "what can I compost?" Their tutorial are very good.

You may have read that people plant directly in the lasagna material but IMO that requires adding some soil in the planting hole and if you can't dig at all in the soil in that area your plants won't be able to easily grow their roots in it either.

If you are not growing food crops and have a source of manure you could certainly use it in a lasagna bed. It can even be used fresh as that will speed decomposition.

One thing people are sometimes concerned about is the depth of a lasagna bed. It will settle about 50% so if you build an 8" layer it will decompose to about 4".

If this area is in a prominent place in your yard and you want it to look neater you might build a few layers of the material suggested above, cover with some layers of newspaper, then place a layer of mulch on top. It will discourage weeds, moisture will be retained, and the soil organisms will be at work. You could place some potted plants on top of the mulch this year for a more decorative bed or even bury them in the lasagna material.
