After talking to them, proceed to the room directly to the west. Search the crate in the north-east corner to get a piece of pure essence, which has a flip option on it. Clicking flip turns it into a life rune. Proceed to the cabbage patch to the south-west of the house and search the scarecrow to get a cruciferous mounting. Then go north-east into the courtyard and search the water barrel in the north-west corner to get a brussels sprout.
