I have something to share with people who feel totally daunted by the life changing experience and the equipment necessary for larger than an acre homesteads. I am 62 years old, widowed, l and thyroidless and I have 2 immune disorders that make it hard for me to eat out or even at the neighbors, allergies to most medications, arthritis, carpal tunnel and I still do almost everything that needs done and what I can't do, I have neighbors who can. I also have blackberries right now and they make happily accepted payment for sharing a bit of their skills. I came here after becoming a widow, ended up on the most wonderful 3.6 acres of Alabama clay in a little wild holler of my own where even traffic noise does not venture! I love it!
First I had to have cut down 1.5 acres of 100 foot pine trees but I left the 1/2 acre of hardwoods across my stream. The ground up stump pile of one of those pine trees grew 20 pounds of sweet potato's the next summer. 4 years later, it is all covered in fruit trees and bushes and and fruiting vines and I am now finally figuring out the next phase of permanence for plants there and what will grow in my damper lower acre in front of the stream.
I suggest that many people who really want to do this might be more receptive and less afraid to try if they were to check out the newest battery powered equipment. I have an 80 volt 21 inch cut push mower that is equal in power to that brush doctor thing. Weighs 35 pounds, battery weighs 5 pounds. 4 cutting heights. Beautiful cut. I can work it and lift it easily. I also have 80 volt chain saw - even I can use it well! Also 12 volt weed eater that is so easy to use. 12 volt tiller for beds - no use trying to till this land - it's full of crystals and iron (pretty sure that at some point in lost history there was an iron forge here). I also have a TroyBlt Mustang 52 inch grass hog - used it all over DC Maryland and Virginia before I left there in 2013, still working like a horse (when it's not raining. pssst.. the little battery push mower cuts places even my little red mustang won't.
All of my blackberries were free gifts from nature and so far this year June of 2018 I have picked over 4 gallons while others are just now starting picking - all because I watched how they grew by themselves and learned to make them just as a comfortable in way that I can stand and pick a quart in two steps. Then move 2 steps and do again.
You have to learn stuff like that and you have to not play against nature. Nature is quite agreeable with vertical farming with a great many plants. And she loves to play but she has a way of winning if your plans aren't what she is capable of giving in the moment. Patience and common sense should become very much a way of life before you lay down your books (which you will pick up again anyway!) and dig that shovel in for the first bite! And in case of emergency - open YouTube!
Never weed your lawn. Where you foot steps fall, nature will give you what you need. See what nature is offering you. Seriously. It's the truth. We are loved immensely by the universe and that's been hidden too. If you can't see the picture of what your land should look like, nature will show you if you open your eyes and see it. If you do, you can see which plants grow well together and which don't for the plants in your 'zone' and your neck of the woods.
In 2015 I sold persimmons for $10 a quart to local restaurants who use local and wild picked foods. Lots of restaurants especially those in larger towns will buy homegrown or wild crafted goods. This 'farm' has gone from a two bedroom trailer in the woods in 2013 to a home, a barn, greenhouse, a tiny house and orchard and herbals. All my outside lighting is solar, even the chandelier on my deck. I'm loving it. I'm not planning on farming large scale. I just have a large scale to fill with something good! I'm getting one of those movable chicken coops with fence soon for the back acre - probably will sow amaranth there too. Can hook it up to the green house in the winter if I change some fencing.
Learn to trade with your neighbors, sell your crafts and herbs if you don't have left over produce. Sustain yourself on good foods and wild foods even if you live in a suburban type place. Out of your own yard. Some do it on 1/2 acre. I think I have that book too.
I checked the USDA Agg 2017 zone map and Alabama where I live is now zone 8a - same as Seattle and I know that avocado grow there so now I can plant my seed grown trees out of the green house. Still be 8 more years before possible fruiting so I will probably get a couple of grafted proven fruiters since I eat one every day. Sustainability and flexibility go hand in hand. It's hard work doing it alone but it's well worth it to me. And fun too. And pretty. And tasty. And it's mine. Yep, it's worth it. The whole point is not stress over being sustainable but be always prepared for anything.
