Rid odors with tea bags.~ This works. We have had a stinky closet since we moved into our house 5 yrs ago. We tried everything we could think of. It helped but still smelled until we hung a tea bag. That did the trick.
The newspaper will prevent any grass and weed seeds from germinating, but unlike fabric, it will decompose after about 18 months. By that time, any grass and weed seeds that were present in the soil on planting will be dead. It’s green, it’s cheaper than fabric, and when you decide to remove or redesign the bed later on, you will not have the headache you would with fabric.
