There is always one in anything you do. It is also worth saying how interesting I find these discussions on different ways of doing things either in this country or others. I do versions of lasagne gardening, how much I add is up to what I have available at the time. I work on the principle of owt is better than nowt😉
I agree! When I didn't have access to much materials where I lived before, I begged, borrowed and scrounged for it. I contacted tree and lawn services for their bagged leaves or chips, I found chip dump sites out in the country and asked about them...then brought them home(I know a lady who does this all in the trunk of her car..even manure!).
I still do that and I currently pick up bags of bagged grass clippings from people who leave them out for the trash service in town...it's just a dab but every little bit counts. Newspapers, shredded paper from local offices, old mulch hay that farmers were trying to get rid of, hair clippings from local salons, sawdust from local saw mills, leaves raked from the yard and the nearby woods, free manure/sawdust from horse farmers, etc.
You name it, I've scrounged for it. It's sort of a hobby of mine to get useful things on the cheap or for free.
It just takes work, but in the end it will pay off in not having to cultivate the land each year before planting and it also pays off in weed suppression, the richness of the soil and in total harvest.
