Macadamia tree

Jake Jeffries · Oct 3, 2020

Hi all, i need some help to find out what's going on with my macadamia trees,I live in North Queensland, I have 2 trees next to each other one is grown from seed and one is grafted, the grafted one seems to be doing better, the leaves are all turning brown and dropping off, the seedling one looks like it's dying, I fertilized with a fish and kelp Allround fertilizer, they get plenty of water, I'm not too sure what is going on, any help would be appreciated.

How long have they been in this spot? It could be sun burn, could also be a fungal issues.

I planted them at the start of July but had them it pots since January in full sun, the seedling one has always had a struggle with the sun but never this bad, if it's a fungal issue, would you have any idea what is could be?
