I made a plow that will go 24 inches deep, BUT takes a 5 bottom tractor to pull it that deep. at 18" one of the 560 will do the job.
When we harvest a cabbage head, we use what is needed for 1 setting then put the rest in the fridge til the next day. One head per year goes into the freezer cut up and stuffed in quart bags for soup or fry. We love fried cabbage!
The food bank takes about 200 heads a year and say they are great, so as long as they get used I guess size is not important.
One lady here get a couple to make kraut with. One head fills her 5 gallon crock.
We have 10 Earth boxes that we used at the other place when we didnt have room for a garden and I still use a couple of them to start seeds in to transplant later.
You can grow a lot of veggies in big pots with good results if you cant do a ground garden!
We try to get all of our needed seeds early before the places run out. Last year we heard that a LOT of people did get seeds because they waited too long.
Our onion and sweet potato plants are on order and paid for. they will be shipped at planting time here.
