Before you mulch

Before putting down mulch make sure you’ve removed all weeds from your garden

Putting a layer or dressing of compost down on your garden before mulching will help ensure great growth

Determine what type of mulch you would like to use. The amount of t you need will depend on what you are using as mulch, see table below

How much mulch?

A safe depth for mulch is generally 2-3 inches

When mulch is sold by the cubic yard calculate the amount your space will need to follow these four steps:

  1. Multiply the length of your garden by the width, this will give you the square feet
  2. Decide how deep you want your mulch to be in inches (see below for details)
  3. Multiply the square footage you discovered in step one by your desired depth
  4. Divide the number by 324, this is the number of cubic feed of mulch you need
