What should I plant in last years onion bed? Same bed has been used for four years. Where should I rotate the onions to? Tidewater Oregon.

Thank you for your question. I am uncertain what size of garden bed you have. Commercial growers are advised to rotate onions with "corn, wheat, potatoes, sugar beets, alfalfa, and other crops." https://agsci.oregonstate.edu/mes/sustainable-onion-production/crop-rotation Extension also recommends that you rotate crops annually.
If you are a home gardener, the following has a rotation schedule that you can use over 4 years: https://extension.wsu.edu/snohomish/gardenrotation/
Just don't plant the same plant family members (in this case, onions, leeks. garlic and chives) year after year. Hope this is helpful. Good luck!
