yes, the expense of hauling soil in for your garden is the white-knuckle part of the whole thing. And I do think that one big haul is probably better than several small trips. Especially if you're doing all the work yourself. That's asking a lot of your body!! You'll be really sore for a week afterward. Having the material onhand to distribute at your leisure is probably much easier on back/knees/shoulders, etc.
I remember the year we put in our garden beds - YIKES!! Very expensive year for us. And a first year garden doesn't yield much. It took a good whole three years for it to start really yielding. Problem is, around year 5 you have a lot of maintenance issues show up - so I am not sure that they ever really pay for themselves, overall.
Raised beds differ from food foresting in so many ways. Rather than build up the soil you already have, with chop and drop mulching, using the
root systems of
trees, etc, one has to supply
everything needed in a raised bed garden. The idea of burying some organic material (log/stump, hay bale, etc) sounds like a good marriage of both concepts.
I do use quite a lot of homemade
compost in my raised beds, for the organic material. It improves my soil so much. In NE OK, I really need the soil to hold moisture. I added kelp &
nettle, too, to see if it would help with moisture retention. Our summers are blazing hot, and it doesn't rain for two months (July & Aug, usually) at a time. I supply what I can from a garden hose. But I still lost so much due to lack of moisture this last year.
I think you are so very fortunate to have younger people interested in doing this with you!! Especially if one of them is in charge of the animals. They will be there to carry on the legacy for their own children and grandchildren. I happen to really like that idea.
As I stated before, I haven't been able to talk anyone into doing this with me. Being a 51 year young grandmother myself, I am not at all sure I want to tackle this on my own. My children are ages 20-30, and my grandchildren are ages 6-12. I think the older grandkids and maybe one or two of the sons/sons-in-law might be interested in things once they are going. Just not "into" helping me get them started.
I have a question for you (or whomever would like to
answer it). I am an ethical vegan. Is it possible to do food foresting without animals? (at least not those intentionally kept) Can this be done successfully with wild animals, indigenous species, etc?
