Underwatering is more of an issue than overwatering - especially in pots. A bit like Camellias and Rhododendrons going short of water in late summer and affecting the new buds, if Acers go short of water in spring, it can affect the leaf tips. The bigger the canopy gets, the less rainwater gets in to the roots too. Wind will also dry out foliage very quickly. Make sure you do as the others have said about refreshing soil each year too. A mulch will also help - gravel is ideal. Potted plants of any kind need more attention.
It's more likely to be frost though. All the ones where I work are the same (happens every year) - and they've been there for decades. They always recover.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
