If you can find them free or cheap, food grade 55 gallon drums cut in half make great containers, so do 5 gallon buckets. Both will need lots of holes drilled in for airflow and drainage. I continue to increase my container count. Hoping to grow enough tomatoes this year to can up a bunch. I've been out of whole and diced tomatoes for more than a year and mine are way better than what I get in the store. When it was just DW and me (me being the only corn eater) a 4'X10' raised bed with about a foot of soil produced enough corn to eat through the season and freeze a little. Figure each plant will give you 2-4 ears (avg 3). I need to get the soil tested in my former pig pen, which housed my compost pile prior to the hens discovering it. The pigs tilled it pretty good and removed all vegetative growth. Considering planting corn there. Now that I have the LGD, deer are unlikely to raid it at night.
