WHERE & HOW TO FARM
Where to farm
Around garden plots after harvesting mature crops in the Valley.
The dependable route is to grow and harvest crops, then pick up Rich Soil when it appears around the field. It is an occasional drop rather than something planted directly, so plan for repeated harvests if you need more. Keep the material in storage until you know which recipe or quest needs it. If you plan to craft with it, check the current recipe list before spending your stock.
