What do you put around raised garden beds?
Herein, what should I put around my raised beds?
A couple layers of plastic sheeting followed by 3-4 inches of driveway gravel would probably do the trick. Organic matter and water in the paths (broken down mulch and run-off from the beds) is likely what is giving your weeds an ideal spot to grow.
Also know, should I put landscape fabric under raised bed?
They will compete for water and nutrients with the plants you want to put in your raised bed. The landscape fabric will help keep them out but some roots may still find their way in. The depth of the soil in the raised bed should prevent weed seeds that are in the existing soil underneath from germinating.
Because many plants require well-draining soil, placing rocks in the bottom of a raised bed to create additional drainage space below the soil is a sensible step. Unlike soil, rocks will not degrade or compact over time.
