You could get potatoes, squash, pumpkins in now which would give you some return from the plot this year by late September and get fair bit of ground cover in and start breaking the soil after grass. you could green manure that section or horse manure over winter. Otherwise you’re not going to be seeing much come out till june next year when your overwintered onions are coming out, which can be harder to keep interest up.
