Raised Garden, Help with next step..
We just built two garden boxes measureing 4ft by 8ft and they are 12" height with a 2" cap. They will be placed where there was an existing raised bed (pevious home owners used treated wood). Other then a small section that I dug into this was sectioned off as a raised garden and I am not concerned about weeds coming up underneath.
I am ready to place the boxes in there homes but I don't know what if anything is need before filling. I have seen people put down cardboard or newspaper then fill up. I will be using as much as the existing dirt as I can however it certainly needs to be amended and made more rich. How much of the existing dirt should I put in and how much amendments should be placed in? What amendments would you suggest putting into the soil? I appreciate any feed back you have, thank you!
Here are pictures of the existing area and one of the boxes:
