Aoyagi means green coral and the green coral bark is considered to be the most outstanding feature of this tree. The leaves in spring come out an amazing chartreuse before turning more green in summer. Autumn colour is fiery orange and yellow.
This upright-growing tree is not very vigorous and can reach 8m high.
Like all Maples Acer japonicum 'Aoyagi' doesn't require any pruning routine. Remove any dead or damaged branches. The best time to prune is the late autumn or winter when the plant is fully dormant.
In late spring you may add a top dressing of a multi-purpose fertiliser around the base of the plant.
