|Susan said that, add a 2-inch layer of mulch. But be sure to keep it away from the main trunks of your rose bush. Why? I thought cover so weed can't grow there too. No? Thanks

|You're right, mulch will help suppress weeds but if you pile it up against the trunks or main stems it can hold moisture against the bark and cause it to rot. Just keep it an inch or two away from the main stems and it will suppress most of the weeds.
