Is Free Mulch Worth It? (Gardening Tips ‘n’ Ideas)

Read at : Gardening Tips ‘n’ Ideas

Like most things in life you get what you pay for and the rule doesn’t change when it comes to free mulch. For a while, our Shire was offering help-yourself mulch where any ratepayer could come and take their own. Now, they charge for it. We still have to shovel it ourselves – not the most pleasing of tasks – but they also demand $5 for a trailer load. Yet, it hasn’t gotten any better. In comparison, the local soil companies charge a minimum $40-60+ for a trailer load so, relatively speaking, it’s still free. The difference is that the expensive mulches have usually been packed with composts, organic manures and materials sourced from who-knows-where. They have cute names like “Jungle-Mulch” or “Enviro-Mulch” and you can feel the rich earthiness from each shovelful. Yet, when it comes to performing the task of a “mulch”, do free mulches function any differently to their more expensive counterparts?

In my experience, having used both, I have noticed one glaring difference. The free mulch that I covered some of my garden beds in 3 seasons ago is still there while the expensive stuff that I bought at the start of this season has almost dissipated. What was the difference? Size.

The free mulch consisted of very loosely chopped twigs, branches and leaves with the odd weed thrown in for good measure. The expensive stuff was so finely shredded that you couldn’t decipher any of the individual ingredients. And while it looked great for the first month it’s now breaking down so quickly that, as a mulch, it has almost become useless as we head into the season where my garden needs it most.

Is this a ploy by the soil companies to get me to keep buying their product? Or, are we blurring the lines of mulches and soil improvers so much that they’re becoming almost as indistinguishable as their individual parts? gives the definition of mulch as;

MULCH – Any loose, usually organic material (can be small pebbles) over the soil as a protective covering or for decorative purposes. Common mulches are ground bark, saw dust, leaves, pine straw or eucalyptus.

while defines mulch as;

1. a covering, as of straw, compost, or plastic sheeting, spread on the ground around plants to prevent excessive evaporation or erosion, enrich the soil, inhibit weed growth, etc.

One says that it’s for soil protection while the other adds an enriching component. Which is it? Or has it just taken on a multifunction like 2-in-1 shampoo/conditioner?

I guess it depends on your own personal view and what you’re trying to achieve in your garden. The feeding mulch that enriches your soil is never going to come for free while the free mulch will never look as stylish as the glam-mulches that eat into your gardening budget.

Where can you get free mulch from?
