Brachychiton Trees

The Brachychiton trees planting in hot season, is that enough to raise the mortality to 50%? I planted around 400 trees. I had to hand over my project and no time to wait. So now I want to replant in September. What you think, replace this kind of tree or plant it again?

It is best to plant young trees in a cooler season.
Watering daily is essential along with proper growing conditions.
I would access the planting area again and then make a determination on the variety of tree you would like to plant.

Brachychiton Rupestris Gumosis

I live in Murray Bridge in South Australia and have a mature Brachychiton rupestris Bottle tree. Last year I noticed some of the mature seed pods showing signs of gummosis. This year the signs of gummosis seem to be abundant and infesting the green seed pods. Any ideas on 1) What causes it and 2) How to cure it?

Based on the appearance of the pods, the most likely explanation seems to be damage from insects or other pests feeding on the pods. The pest damage could then cause the gummosis and allow rot in. I am not sure of specific ways to control this unless you can find the pests that are responsible and identify them.

Australian Bottle Trees and Their Seeds

I have 3 Australian bottle trees in my yard. I would like to know if the nuts inside of the seed pods are safe for dogs (also people). My small dog has started to eat them and absolutely loves them. I try to pick them all up but there are so many now. Are these healthy for him or harmful in any way? I found one web page that said they were healthy for people to eat but it did not have much detail. I have been done multiple online search without finding a definite answer. Please help! Thank you!

The gum exudate can be eaten, the taproot can be eaten and is described as “carrot-like” or “yam-like”, and the seeds can be ground up and used as a coffee substitute. The raw or roasted seeds have been eaten by aboriginal people and are high in protein, zinc, and magnesium.
I can't fine any information on the toxicity to dogs.
Check with your local vet for information on the safety of your pet consuming this tree.

Kurrajong Tree

Hello
after some heavy rain we had this jelly like substance coming out of the tree mainly around the seed pods. It made a big mess in the carpark. Quite slippery when you stood on it.

This is more than likely a reaction to the excess water. Many plants will exude this in the form of sap. There is not much to be done until the area dries a bit. This will return the tree to its normal state.
