I mainly do container gardening, but my husband built a raised bed for larger tomatoes and some trellises for the cucumbers. The past three years I've had more cucumbers than I know what to do with, but this year almost nothing. I'm assuming it has to do with crop rotation - it's the fourth year in the same spot. If I switch out the tomatoes from the raised bed and with the cucumbers for a couple of years will that help to replenish the soil? Not sure what either plant takes from the soil. Appreciate any advice. thanks
