Kel and I first “met” when she rang one afternoon from Queensland, to discuss Air-Pot bonsai containers and her new baby, a Western Australian Saltwater Paperbark (Melaleuca cuticularis). This was a week before Cyclone Alfred hit early March this year 2025, and the stories she had about that! We kept in touch as best she could under the circumstances — I just wanted to know she was ok — but they make them tough Queensland-way, and she, her family and her 160 bonsai (!) all made it safely through to everyone’s relief.

160 bonsai!!

Kel, by the way, is the one who shared that oh-so-obvious-in-hindsight tip of lining the base with fine coir to stop a fine potting mix falling through! That was quite the game-changer for me, thanks heaps Kel!

Here is her bonsai mix — she uses a 2:1:1 or 1:1:1 mix of akadama:scoria:pumice, of 3-6 mm particle size, and will sit a more water-loving plant in a shallow tray of water.

Here is the saltwater paperbark when first potted up on 18th March 2025 into a 9.4 L Air-Pot bonsai training pot.

When I went to work on the plant I was blown away by the growth since 18th March!

From memory I put a small amount of coir mix in the bottom of Airpot then mixed Akadama, Scoria (I use Black), Pumice with Coir mixed thru it and potted my Saltwater Paperbark from WA into the Airpot.

As you will see the Akadama, Scoria and Pumice alone would have fallen thru the bottom holes without mesh hence is why I used pure Coir to prevent that from happening and I didn’t have any mesh at the time of potting Saltwater up…
