mulches, often made of stone or plastics, tend to stay in place, do not rob the
soil of nitrogen, and do not harbor weed seeds. However, they have numerous
disadvantages when used in the garden. Over time, stone mulches can migrate down
into the soil making future digging difficult. Light-colored stones can reflect
heat onto plants, scorching sensitive plants. Stones also tend to work free of
beds and can be thrown by lawn mowers, potentially causing injury. Perhaps the
greatest disadvantage, however, is that these mulches do not contribute organic
matter to your soil.

These mulches are available in a wide variety of textures, colors, and
materials and are used in rock gardens, driveways, and walkways. Think
carefully and be certain you really want this type of mulch before putting
it in place, because these mulches are more or less permanent. It is
best to underlay these mulches with landscape fabric to reduce movement of
stones into the soil. Once gravel becomes mixed with the soil, it is nearly
impossible to remove. Many gravel and stone mulches are made from limestone
and cannot be used around rhododendrons, mountain laurels, and other
acid-loving plants. When leaves, twigs, and other debris fall into coarse
rock mulches, they are difficult to remove and can make the mulch
considerably less attractive. |
Plastic works well for keeping weeds down and retaining soil moisture.
Although it prevents water from leaving the soil, it also prevents it from
entering the soil, making it unsuitable for landscape plantings that depend
on rainfall for their water supply. Plastic is best reserved for vegetable
gardens, where irrigation systems can be placed under the plastic and bare
spaces left between rows to allow water entry into the soil. |
These are fabric mulches of polypropylene or polyester. They work much as
plastic does, but allow water and fertilizer to enter the soil. For the best
weed suppression, choose closely woven geotextiles. Generally, the fabric is
placed on weed-free ground and covered with another mulch, such as wood
chips, to improve its appearance, keep it in place, and reduce damage to the
fabric by the sun's rays. With these mulches, it is important to remove
weeds as soon as they are noticed. Otherwise, roots can grow right through
the fabric and become difficult to pull. |
