I knew Australia was on the bottom of the world, but I never realized that pictures from there would appear upside down. I tried twisting my neck to see the picture the way I'd expect it to look up here closer to the top of the world, but I still can't tell much and am not about to hoist myself upside down from the ceiling just to see the picture.

In general, just like most other trees, pick a leader and limb it up as it grows. I probably wouldn't remove all the limbs any higher than the bottom 1/3 of the trunk.

Thanks Brandon7, weird re image, it was the right way up when I previewed the post!

Thanks ashratam. I've uploaded a few new pics, it's growing we'll, but I'm still too scared to prune in case I ruin the eventual shape. Even though it is in our front yard, I am wanting to create a high spreading canopy rather than a bush. Our little tree has grown at least 2 meters since we planted it in January. No special care, but the soil is quite clayey and we had an incredibly wet and hot summer here plus it gets sun most of the day. The tree definitely liked these conditions!

Leaves of my cassia fistula tree (still small, about 2 and a half metres high) have turned brown but it is still alive. What can I do to restore it to green leaves? Also, how do I prune to minimise height i.e. I would like it to be less than 5 metres high) so should I cut off the top please? Thanks 😊 Anne

I have the same problem in Qld. I have planted it on my front boundary (no fence) and I wondered if it was a mistake? It is about 6 metres from the house. I don't want it to become enormous and worry about the roots? Can I just chop the top off?
