take you finger nail and scrap a little of the bark off ifs its green underneath then there is still life in it

If it's a Japanese Acer then join the party Guest. All mine are looking 'orrible but on close examination, they are just showing signs of life.

This is a very late year for all plants, shrubs and trees by 'bloom' I assume you mean come into leaf? Our acers are just showing signs of buds. The only deciduous tree with any leaf growth is a weeping mallus.
