I finally got the dwarf lime tree I was looking for in Spring (Bunnings only had dead ones in stock) at a reasonable price, and from a local nursery. Now I just have to keep it alive through the summer heat so I can concentrate on keeping it alive through the winter frosts.

I also got a sprinkler and tap timer so I can give the garden a good soak before this heat wave, and spend less time holding a hose in the future.
