Novice gardeners here. Already feeling overwhelmed. So, I'm taking over hubby's raised bed. It gave us tomatoes over 3 years ago, since then its been sadly neglected. He lined the inside walls with black plastic and was full of weeds. I've removed the weeds, torn up plastic tarp and all dirt down to bottom soil. The base soil still has lots of little weed roots (they look like crazy wires) which I'll dig out before reincorporating the good soil in.
I decided to lower the bed (bad back!) to about 1 foot by removing some boards. There are gaps between them though. Should I line the inside walls again? These boards are about 5.5" wide. If I don't line I'm afraid my dirt will seep out through the gaps. Any pros for notlining? I also plan on removing about 4 inches of the grass leaning up to the raised bed (highligted with red here). Thanks for your help!
