I would like to introduce you to a free mulch delivery service. Mulchnet has recently expanded to now offer their service Australia Wide (originally operating in Perth). They have thousands of tonnes of mulch to give away for free from the excess that their contractors would prefer not to have to transport.
Of course there is no guarantee of a particular delivery date, and the quantities could be huge so you might have to arrange to share with friends or neighbours. On the otherhand you can always order and pay for what you need if you want guaranteed delivery.
Mulchnet are now a sponsor of iGarden and I think it would be good for users of their service to tell us what you think.
For more information please see www.mulchnet.com
or leave a question here if there is anything you want to know and Tim from Mulchnet may be able to answer your queries.
