Pine needles as mulch for roses?

14 years ago

I'm contemplating what would be a great mulch for under all of my beds this spring. I have a couple of beds with hosta's that I'd like to use pine needles with to deter slugs. I also have my rose beds and other perennial beds. What I'm wondering is... I'd like to keep the mulch type the same I think for all of my beds, but also add to the soil. Would pine needles work? Or do they take way too long to decompose and work their way into the soil? Does anyone else use pine needles under their roses?

Last season I used mini pine chips and they did work great, but they won't deter slugs at all. Although they do break down quickly and add to the soil.
