Trying again - prepraing weedy raised beds for new garden
What's the best way to prepare some overgrown, weedy raised beds for planting when spring comes? My raised bed gardens last year were pretty much a flop so I am trying again this year. One of the problems we had last year was too much weeds. Although we weeded and we put down a straw mulch, grass and weeds kept on growing from the edges of the beds and it was overgrown quickly. We plan to mulch at least a foot or two on the ground away from the bed this year, which might help.
Anyway, what can we do now to prepare the beds? Right now it's filled with a ton of yellow-dead grasses and weeds. Should we pull the weeds and then cover it with mulch or compost? Should we dig out all the of the soil and redo the bottom layer of cardboard that we put under the box? Or something else?
Any other tips would be great. Thanks
