Natalie in case Fred doesn't get back on for a few days because of the storm I'll answer this question and he can correct me later if I'm wrong
The beds that he's going to let grass grow back over are just there temporarily. His son is getting beds ready at his place but they weren't ready for the seedlings this year so Fred made some beds for him. Also, Fred made a lot more seeds than normal so he planted them in this bed also. So after 2 years all the CHOSEN ones will be dug from these beds and the other seedlings composted and he won't need them any longer.
The other beds stay in place and just get tilled and admended every couple of years (or when the seedlings are removed)
