Hello everyone, I am brand new to gardening and my wife and I are planning to grow our own fruits and veggies next spring. I have recently built an outdoor compost bin and a tumbler and started piling material for composting. We have mapped out eight 4'x8' raised bed boxes on the back side of our property. My question is should I till the bed areas and build the boxs now or do it in early spring? Any info would be greatly appreciated. Oh we are also in zone 5. Springfield IL to be exact. Thank you!!
