Ya our FC is worried about it too, as we do have a medium house but the garden plots are always in use, and the thought of dividing it between everyone to grow choco food is worrying to say the least.
It would all be ok if gardening plots were per person, so each can grow their own.a bit like each person can use stables to raise their choco.
Of course we do not know full details yet so I'm hoping they planned for this and it won't be some item that costs 300-500k per item on MB
