Is it a good idea to use mulches in the rose garden?
Absolutely, there are many reasons for a thick layer of mulch (2 to 4″). Mulch reduces evaporation conserving water, prevents weeds, helps regulate soil temperature, may have aesthetic value, can be a source of organic matter and in some cases nutrient contribution. There are many different materials that can be used for mulch each with its own special qualities and advantages. The most cost effective is usually what is most readily available in your area. In cold climates organic mulches can be turned in as a source of organic material in the fall and replaced in the spring. In warm climates mulches can be left the year around and added to as thickness is lost to decomposition. Mulches should not be buried up on the canes, the moist conditions may encourage disease.
