I’ve got a big garden, but loved the square foot method so I modified it. Basically went to 24 ft plots separated by 6 ft of grass.
Each plot has a different category. I have five: greens/roots, corn/beans, tomatoes/peppers/eggplant, peas/cabbage/onion family and melons/gourds/cukes/squash which is on a 6 year rotation with one fallow plot for cover crops, and also one permanent plot for herbs and seed saving. I wish I could go the biblical 7 year rotation but don’t have the room right now.
I make 1 or 2 ft wide beds by going over it with a tiller set 3 in deep and then with a broad fork to loosen it to about a foot, and a second pass with three tine fork if necessary. Then hill it up like I’m doing potatoes and flatten off the top to a 3 to 4 in. deep bed. Between that and broadforking it makes for a 1 ft deep bed without the needs for sideboards and gives access to the subsoil.
Then make my rows in the beds or a trench in the case of peas. The deep soil really boosts the crop yield and with creativity have double crops on a number of the beds. Because 24 foot is dividable by 2,3,4,6,8,12, & 24 you can fit several different things in a bed down to a 1X1 ft square. It’s efficient and has worked well for me.
Your beds sound good to me.
the ones in my greenhouse, were too wide and I could not reach the other side. So had to step into the bed.
In the greenhouse they were raised, and I could sit on the edge.
I love greenhouses and hate not having one now.
Or a way to garden, but thinking about it is fun.
