Q.I Have A Small Blessed Mother Rose Garden. I Have Two Roses That Were Planted There In The Last Five Years.
Last fall I planted some tulip and hyacinth bulbs around the roses that bloomed this spring. I mulched it well last fall. I have weeds that are coming through the mulch and I want to add an additional rose bush. What can I use to kill the weeds, but will not harm my roses?
