(If you're really curious about it you can use the old treefarm version (1.2.7) in connection with the map, the mod versions don't differ that much currently)
This is shown in the very first screenshot in the OP (although with outdated graphics). You can ignore the blue-ish items, which is fertilizer, but it's optional. So what you have to do is process raw-wood into germlings and supply the field with them. The field starts autoplanting them and as soon as they are grown, it will harvest the trees and put the wood into the chest from which you can extract it then. And you don't have to supply it with fuel, I know that this is possible, although it's not intended.Berserker55 wrote:I've figured out how to extract wood from a farm, but how do I automate planting?
