Answer: Cedar and cypress are both fine mulches. A woodier mulch tends to temporarily tie up nitrogen in the soil, so you may need to add a little to compensate for that effect. My personal preference in a perennial bed or mixed border is double shredded hardwood bark; the texture is a bit finer and the bark does not tie up the nitrogen the way woodier mulches will. Any natural mulch will do the job and will also help feed the soil over time as it breaks down. Sometimes local avalability is the determining factor along with relative cost. When you mulch, make sure you place it around but not touching the plants.
