Spring and fall are perfect times to check and see if your mulch needs replenishing. Mulch depth should be maintained at 2 â€“ 3 inches thick.
When maintaining mulch be sure you use the same kind of mulch that you already have down or it will look patchy or layered. If using a new kind of mulch, remove the old mulch first.
Old mulch can bunch up so before applying new much rake the old mulch so it is even along the landscape, then apply the new mulch on top.
Make sure that mulch is not up against trees as it invites pest and rodent activity and encourages disease.
