We chose not to rototill our garden in the first year but I would definitely have done it knowing what I know now. Unless your soil is good then rototilling and adding as much organic material as possible (also lime, rockdust, fairy dust, kelp etc) then sowing a covercrop mix, then following that with
cardboard,
compost, mulch seems to be a great way regenerate and kickstart a garden scale soil.
I know that other people have different ideas, and I'm far from an expert, but the initial kick that you seem to get from the powertool and fertility import seems to give you better soil structure and health much faster than trying to do it by hand
for those of us that are not experts. If you want to do it by hand then good luck to you, it's certainly possible. My
experience has been that knowing so little about
gardening when I started made it hard for me to know if it was my soil that was poor, my garden care that was lacking, my young
trees that were just not that good, etc etc.
So getting at least the soil up to acceptable asap would have taken care of one of those problems.
Also I would have got
chickens on the ground as soon as possible, and in my climate ducks. The slug pressure in this climate (similar to the UK) can be enormous.
Those two videos are wonderful though, I love old solutions. There is also a solution I have seen but cannot find that uses a second person standing in front of the digger, pulling on a rope tied to the spade, just above the blade, to help with lifting the soil.
While looking for it though, i did find this weirdly shaped thing which looks like it makes the work of digging much, much easier. Probably not as good for compacted clay and turf, although you never know.
