It has been well looked after. And that is why I got discouraged! When you feed a tree heaps and look after it and it doesn't move, it's a little upsetting! Since I have had it, it is always been covered in dynamic, and given loads of seasol and powerfeed.
Yes, you watered and fertilised it, but with a bonsai things don't stop there. BTW, didn't you post it here earlier, i.e. about 2 yrs ago? I seem to remember quite a discussion about it at the time, like whether or not to turn the planting around.
Anyway, "looking after" means proper pruning, and in such a shallow pot it means repotting too. You didn't do either of those. If you had checked the roots, you would have discovered your curly grubs earlier, wouldn't you? And you wouldn't have such a poor, undisciplined lot of foliage patches either. THAT'S what's got you discouraged. Sorry mate, you won't get any sympathy from me.
