I just moved into my house a year ago and there are raised beds in the back yard. When we moved, they were covered with weeds. I’m not sure when the last garden was here but I’m interested in growing some vegetables this summer. I don’t know how to get started using an old bed since there’s old dirt already in the beds. My grandmother told me I should pull the weeds then turn over the soil to loosen it up and add fertilizer. Is that all that that needs to be done? Should I add new soil too? Please help!
