Can You Put Bark over Soil

Applying a thick layer of decorative bark to your soil surfaces (called a mulch) does much more than just make your garden look attractive. It helps to retain soil moisture, suppresses weed growth and will gradually improve the structure of your soil.

Do you need to put anything under bark chippings?

A membrane should be laid prior to any bark being placed down. It is best used for paths and play areas or if you plan to use it on your flower bed or border, it is best to do so when the area is new and not yet planted so that you can cut the holes required for your plants to come through.

Can you put mulch directly over soil?

First, lay the mulch down on soil that is already weeded, and second, lay down a thick-enough layer to discourage new weeds from coming up through it. A four-inch layer of mulch will discourage weeds, although a two-inch layer is usually enough in shady spots.
