Hey Dalia....Slugs can definitely be troublesome in the garden. As for slugs/snails and roses, it definitely is possible that they can munch on the leaves of a rose; however, most slugs/snails are not willing to climb up a prickle-laden stem. (That's right...I didn't say thorn-laden. Roses actually don't have thorns...they have prickles). The prickles on the rose stems and sometimes leaves are usually good enough to deter the slugs from climbing up. To control slugs/snails in a garden there are several ways you can create a perimeter around you plants that they won't cross. Snails and slugs will not cross a copper barrier. You can purchase copper foil that you can wrap around trunks or flower boxes, and the slugs will not cross them. Snail-Barr is such a product. Also, you can use diatomaceous earth around your plants. Diatomaceous earth is made from dead microscopic sea plankton. These plankton have cell walls made from silica, which makes their exoskeletons like little shards of glass. Snails that attempt to cross the diatomaceous earth perimeter will cut up their undersides. It is important to know that breathing in the diatomaceous earth is not good for you either. It irritates your mucus membrane and you should still wear a face mask when using diatomaceous earth.
