Like any organic product mulch decomposes, which is beneficial to your plant material and unfortunately promotes weed growth. Mulch also disappears naturally by wind and rain. Additional planting will also deplete your mulch layer. Lawn and landscape maintenance services like blowing grass out of mulch areas after mowing or cleaning up shrub clippings after trimming also deplete your mulch layer. Therefore, your landscape mulch must be refreshed from time to time, we recommend annually. We highly discourage non-organic product like rubber and brick chips, they do not add any nutrients back to the landscape plantings. We offer hardwood mulch in both brown and black or pine straw, a mixture of them can be cool. Mulching is the most cost effective way to improve curb appeal, so let’s do it soon.
