Use several layers of old newspaper in place of black plastic weed barrier if you want a more environmentally friendly way to reduce weed growth through your mulch. Lay the newspaper down and cover with a 2- to 4-inch layer of organic mulch. You’ll have to replace the newspaper and mulch more often, however, because the newspaper will biodegrade over time. Fabric weed barriers are another option, though they aren’t always as effective as plastic in preventing weeds from growing.
Cut small “X” shapes into the weed barrier if you want to plant new plants in the area before laying the mulch. Dig a hole in each “X” shape and place one plant inside each hole.
Rake the area smooth and remove any old mulch, rocks or debris that could poke a hole in your weed barrier.
Spread a layer of black plastic weed barrier over the planting area. If you already have plants growing in the area, cut holes in the black plastic to fit over them.
Things You Will Need
Weeds are the enemy of gardeners around the country. These pesky plants decrease the beauty of your yard and rob vital moisture and nutrients from your flowers, vegetables and lawn. Mulch helps minimize weeds but also retains more moisture and helps moderate the temperature of your soil. The trick to keeping weeds from growing through your mulch is to put a layer of weed barrier underneath.
Pull up any weeds that are already growing in the area you want to mulch. Use a trowel to help you remove the roots of the weeds, which will decrease how many try to grow back.
Black plastic weed barrier
Overlap the strips of black plastic weed barrier so weeds can’t sneak their way through the edges of the material.
Apply a 2- to 4-inch layer of organic mulch over the entire surface of the black plastic weed barrier. Spread the mulch over the edges of the weed barrier so the black plastic doesn’t show.

As with most types of prevention, discouraging weed seeds from sprouting requires some extra time now so you can save a lot of time later.
Left unattended, weeds will quickly fill in unplanted areas and any open ground around plants. Mulch spread over the soil surface blocks the sunlight most annual weeds need to take hold. Weeds that do sprout are easy to pull because soil beneath mulch remains loose and moist. Coarse chipped or shredded bark is a good choice for large areas between trees and shrubs because it decomposes slowly and doesn’t easily blow away. For paths, a thick layer of sawdust provides good weed suppression because it depletes nitrogen in the soil.

Too little fertilizer can lead to sparse lawn that loses the competition with weeds. Too much helps nurture certain weeds, notably annual bluegrass, Bermuda grass and crabgrass. Strike a balance by following the application rates on the package. And use a fertilizer with a high percentage of controlled-release nitrogen, such as sulfur-coated urea, ureaform or IBDU. These provide a slow, steady nutrient supply.
