Acer shirasawanum, help!

hxt01267hxt01267 Posts: 1
Ive had a lovely acer in a pot for a few years with no problems until the last few weeks.

There's two issues with it, firstly holes in a number of leaves. I assume this is some bug eating away but despite spray and pellets it doesn't seem to be making a bit of difference. Any ideas?

Finally it's the bigger of the two problems, a number of leaves are looking dead and brown. Is this the recent weather or something I can correct.

Any advice gratefully accepted. :(

    How big is the tree and how big is the pot? I  think this is quite a vigorous cultivar,  and may need more space. Acers in pots need water every day when it's hot and dry. Hard to know what is making holes-sorry.

    I'm sorry, but spraying plants when you don't know what's wrong is a really bad thing to do. 
    Need to see the whole shrub in situ. Impossible to advise from photos of leaves which have been removed.  :)
    As @Allotment Boy says though, drought [and inconsistent moisture ] plus sun and wind, or a combination, are the most likely reasons. An exposed site and too much sun is a particular problem for the green or yellowy ones. Those problems can get magnified if the pot is too small, and if soil isn't being replaced, or at least refreshed, every year, as there aren't then enough nutrients available. 
    It's a place where beautiful isn't enough of a word....
