What factors affect the cost of mulch?

Depending on the type you want, different types of mulch have unique costs. You should also consider the size of the area you want to cover, the delivery and installation, as this affects local mulch prices.

Mulch type

There are two kinds of mulch: organic mulch and inorganic mulch. Organic mulch is made of plant materials, compost, leaves or grass clippings. On the other hand, inorganic mulch is rocks, gravel, plastic sheeting, and rubber. It is usually artificial and can last much longer. However, organic mulch can be a better weed barrier than the other and can contribute a lot to the quality of your soil.

Garden size

The amount you will be paying will depend on the area you want to be covered. Buying bulk mulch can be done per square metre, cubic metre, or bulk bag. The bigger your area is, the more mulch you will need. The recommended depth of mulch is 3 inches. Here is a sample computation:


Price per m²

Minimum area



100 m²



500 m²



1,000 m²

Extra large


1,500 m²

Delivery and installation

Bulk delivery charges for mulch are usually included in your mulch price as long as you reach their minimum limit.

You can decide to hire a landscape contractor to help you with your mulch installation. Doing this without a pro to help is possible but difficult as it will require too much work on your part, including lots of heavy lifting. See the following labour cost list per region in Australia:

How to choose the right kind of mulch

You want to use mulch in your garden to keep your soil’s moisture, thereby keeping the plants healthy, enriching your soil, and keeping the weeds at bay. It is still best to consult landscape designers to know what kind of mulch to use, but if you want to know a few things about it, here are a few things you should know about organic and inorganic mulch:

Bark and wood chips

Bark like cedar bark, shredded wood, wood chips, and hardwood chips are often waste products of paper and furniture. This is an eco-friendly choice and an excellent one for trees and shrubs. 

Watch out for pine in your mulch, as although this takes longer to disintegrate, it might harm flowers and vegetables due to its acidic content. Wood chips are also great for windy or rainy climates, as it is a heavier mulch.

Leaves, yard waste

Grass clippings and anything that shreds in the garden can be free mulch. It is good to use for flowers and vegetable beds. Watch out for clippings that were sprayed by pesticides, as this can hinder the growth of your garden, and look out for insects that might affect the growth of flowers.


This is considered one of the best ones to enrich the soil and lock in its moisture as it decomposes - all that is necessary for growth. It provides nutrients, especially during the flowering season. It suppresses weeds but does not prevent them. 

Straw or hay

This comes from wheat, barley and oat. This is mainly used for preparing your garden for the planting season, and it also works well in protecting your plants during winter. This is best used for a vegetable garden.

Tiger mulch

You will often find this inorganic mulch around children’s playgrounds or landscaped gardens. It prevents insects and fungus from growing in your area. It keeps weed from growing but is a bit on the expensive side.

Rocks and gravel

This is primarily used in landscaping. It keeps heat and moisture, allowing water and air to reach the roots. It is good at preventing weed growth as well. You might pay additional costs when transporting rocks and gravel due to their weight.

How is mulch installed?

There are many things you can do in your garden when you decide to have it landscaped. You can hire someone to hedge your bushes or trees or level your garden to make room and stabilise the placement of your plants. Of course, you can also hire someone to do the labour for your mulch.

Professionals use mulch blowing for a quick installation. Mulch blowing can cut the time in half compared to mulch installation by hand. It will also take only two people to install it.
