Keep the grass and weeds away
Yesterday I pulled up the grass around my fruit trees to copy Martha Stewart and plant bulbs around them. This way in the spring I have a spectacular bulb show and the harvest time it will be all died back.
My question is How do I keep the grass and weeds from returning? I thought about newspaper but didn't want to hurt or prevent blooming of the bulbs. I organic garden. I thought about mulch but honestly I think mulch is a waste. Will composting it heavy replace it? I thought about a cover crop, but I really don't want to. What do you think?
Thank you in advance.
