Here are some pics of the tree taken a few weeks back. The first one is the old front (after I carved

) and the second is the new front with the carving.

You didn't repot at the wrong time time of year Andrew ? My one and only guess

Thats a common problem on Tridents. I have seen beautiful imported trees from Japan develop this disease after several years in our climate. I suspect its a root fungal problem. I know several imported trees have died from this. Perhaps someone with professional horticultural experience like Craig 60 will chime in here.

I too have the same issue on a trident... Health of the tree picked up last year late in the season but the same problem is back again this year

any help would be appreciated....

Hey guys,

Have a read through these two posts and I think you might be able to find an answer.

I think it could be one of two problems discussed in these but most likely the fungal problem in the first one.

Hope that helps,

Thanks everyone!

I did not repot it this year or last. Time to look into the fungal thingy!

Cheers

I would immediately suspect chemical or fertiliser toxicity. How much are you using both of these?

I also suspect some sort of fungal infection. I have had the same/ similar in my tridents and possibly Chinese elm a few times over the past 5 years. Here it tends to disappear later in the season. I have never treated it but no sign of it last year except for one chinese elm which had 2 branches with miniature leaves.
Interesting that it has never affected any trees growing in the ground.

Less than I probably should.

OK probably fungal then, I've never had it on any of my trees.

Im pretty damn sure its fungal. Brett did a large write up on this and took samples i think to hort experts. I saw it in rockhampton but since moving to the bush 3 years ago not a trace so far. Devestating to tridents which is the only species ive seen it effect. there is a treatment out there but it is NASTY.

So here's a thought. There's a fella on IBC who talks about garlic tee for his seedlings to keep the nasties away. Wonder if it would work as a gentle preventative for fungal problems.

Cheers,

Andrew

Hey fella Garlic is more an insect repellent, however i have heard that an old greek remedy could work, being normal black tea. Make a good brew, let it cool and water through... This comes from an older woman who is a bit of a medicine woman ! She used this on her lemon trees when fungal disease attacked...

Garlic also has antifungal properties so you could give it a try, wont do any harm
