I re-potted the Macrozamia moorei in April and surprisingly the roots looked very strong and healthy. I used a very airy mix with large amounts of perlite, coir and composted bark chips. It will probably be some time before I see if the re-potting has solved the problems that the Macrozamia has been experiencing. Little else has changed, although I am probably needing to water more frequently with the new potting mix, as the airy nature of the mix causes it to dry out fairly quickly.
