The Q&A Archives: siberian iria

Question: Lots of mulch has been put on my siberian iris, will this harm them?

Answer: Siberian iris likes moist soil and mulch can help soil retain moisture so 2-3 inches of mulch is fine. More than that can cause problems so if the mulch is really heavy, remove some of it so only 2-3 inches remain. Good luck with your irises!
