Mulch

A mulch layer around trees, shrubs, planted beds and covering bare ground provides many benefits. In areas that are difficult to mow, irrigate or otherwise maintain, use mulch to replace turf or groundcovers. Also consider placing mulch in shady areas where plants don’t grow well.

Mulch Facts:

• Organic mulch materials improve soil fertility as they decompose.


• Mulch buffers soil temperature, keeping soils warmer in winter and cooler in
  summer.


• Mulch helps maintain soil moisture by reducing evaporation. A layer of
  mulch also minimizes water needs for established plants.


• Fresh mulch inhibits weed germination and growth.


• Over time, many types of mulch improve soil aeration, structure and
  drainage.


• A mulch layer can inhibit certain plant diseases.


• Mulch around trees and shrubs (not against the trunk) eases maintenance
  and reduces the likelihood of damage from string trimmers.


• Mulch gives planting beds a neat and uniform appearance, adding a
  contrast of color and texture that complements plantings.

For well-drained sites, apply a 2–3 inch layer (after settling) of mulch around trees, shrubs and bedding plants. If there are drainage problems, use a thinner layer. Coarse materials, such as pine nuggets, may be applied to a depth of 4", but don’t allow mulch to accumulate to a greater depth. If mulch is already present, check the depth. Do not add mulch if there is a suffi cient layer in place (2"-3").

If mulch is piled against the trunk, pull it back several inches to uncover the base of the trunk and the root fl are. Mulch piled against tree trunks holds moisture against the trunk, and stems and trunks that remain constantly wet are prone to root rot. Mulch piled high against the trunks of young
trees may also create habitats for rodents that chew the bark and can girdle the trees.
