Mulch is one of the best ways to protect your soil and garden from excessive moisture loss, weed infestation, and dry roots. Organic mulch also decomposes over the season providing valuable nutrients to your plant base.

What are the different types of mulch?

There are two types of mulch:

  • Organic (i.e. woodchips, dried leaves) - Certain organic mulches administer vital nutrients into the soil as they decompose. This decomposition promotes healthier, fruitful soil with abundant nutrients.
  • Inorganic (i.e. stones, rocks, pebbles) – While still effective, inorganic does have some disadvantages over organic mulch:
    • Inorganic mulch does not decompose nor provide nutrients to the soil.
    • Inorganic mulch can hold the heat of summer, which can damage or burn shallow or underdeveloped root systems.

Things to Remember About Mulching

  • While mulching can be a valuable addition around the proximity of your trees to protect against damage from garden tools and lawnmowers, take caution to avoid piling too much mulch at the base of the trunk, as this can starve the tree of water and nutrients.
  • Take care in applying stones over fragile or shallow root systems.
  • The best time to mulch is in late spring, before the hot weather arrives.
  • Use a rake to ensure the mulch is applied evenly.
  • When applying for the first time, soak with water to prepare the soil for upcoming weathering.
  • Create a mulch garden. Mulch gardens provide low maintenance alternatives to lawns, infusing soil with nutrients. Apply a good amount of water initially to maintain the health of the mulch.
  • Consult a local garden centre specialist for the mulch most suitable for your plant varieties.
