H Watto, welcome.
Your problem looks similar to a TM that I have though mine shows up on young leaves so they don't get to grow at all. I'm new to maples but have a few that are healthy and one sick one that I,m now spraying with anti fungal [fungarid or similar]. Mine was lime sulphured over winter without help clearly so this week I changed the soil and washed roots thoroughly as an emergency attempt to save it. Hopefully more experienced growers can ID your tree issues better and its not the same as mine.
Any extra info will help others diagnose the problem
eg;when you last repotted/ what soil mix/ where you are, etc. Always better to offer too much information rather than too little.
With luck it will be something other than fungal.
Goodluck

Hi Graham

Was that out in leaf when we had those very hot windy days just recently ?

Just a thought is that a commercial bonsai growing media as in Plugger or the Grange product that Leong sells ?

It has been inleaf now for bout 2 and a half weeks
And the growing media is a commercial one
Ive never had the time or quite know how too
Make my own ( which i would really like to do )
Thanks for your input jc

Hi Graham

I didn't think that it would have been in leaf in the hot days we had, I was just trying to remove leaf burn from the equation.

I would be cutting all of the damaged leaves off and put them in the garbage bin and not the recycle bin.

Just a tip if there are hot days & winds forecast through summer move it into the shade on those days as it will damage the leaf causing burn spots that show up in the fall color.

BTW: I don't bother mucking around with the soil as in making my own as the commercial ones are designed by professional bonsai growers.

Hi Grahame

Just a thought it could have been something having a nibble on them just before they popped.

I'm not a lover of chemical sprays, so I collect praying mantis when I see them and they soon do what they do and you have little white ones on the hunt.

I know that at some shows I have seen them sitting on top of the tree's having a look around.

The only thing to remember is that before you start pruning is to give the tree a shake or use a chop stick here and there to move things you will soon see movement. I found that they don't work all that good cut in half.

The other thing I like around is the Saint Andrews Cross Spider they tend to have their webs up against a wall and not in the middle of where you walk.

Footnote: The wife doesn't though, as well as the occasional tree snake that has visiting rites after the frogs up here on the mid north coast of NSW.
VENOM TOXICITY - the bite of the St Andrews Cross is of low risk (non-toxic) to humans. They are a non-aggressive group of spiders. www.spiders.com.au/st-andrews-spider.html

Hi Grahame

I though that this may be of interest to all?

I found the link's doing research for good and bag bugs for the club.

For years I thought that the little green leaf hopper was cute?

I couldn't work out a couple of seasons ago what was eating the outside of my fig leaves, then discovered the Fig Tree Beetle.

Here is another listing Good & Bad earthbox.com/bug-chart

The Lady Beetle is a good one to have as well but when at larva stage they look like a baddie. www.brisbaneinsects.com/brisbane_ladybirds/

Here is a link of some nasties to have a look at. www.gardensonline.com.au/GardenShed/Gard...tor/PageSize_64.aspx
