Acer palmatum 'Osakazuki' (Acer)

Acers are spectacular trees which generally are outstanding in autumn months. Osakazuki is a particulary fine specimen which turns brilliant red before loosing it's leaves.  

History

Acer is the latin word for 'maple' and 'palmatum' refers to the shape of the leaves which look like a 'palm' or 'hand'. Acers originate from Japan, Korea, Taiwan and Eastern China.

Planting

Dig a hole larger than the root ball, loosen the soil at the bottom and mix in compost or well rotted organic material.  Place the plant so that the top of the root ball is level with the soil surface, backfill, firm in carefully around the roots, stake the plant and water in well. This will ensure good soil and root contact, stability in windy conditions and a good start for the plant.

Propagation

Grafting.

Cultivation

Prefers a fertile, moist but well drained, acidic soil in a sunny position with some shade and sheltered from the wind.

Aftercare

Stake the tree when young and water well until it is established. An annual application of a mulch around the base of the plant will help protect young trees from frost in winter months and in furture years, will help retain moisture, improve the soil structure and fertility. Needs little pruning only to cut out dead and diseased foliage and where necessary cut out crossing branches to retain a good shape.  Pruning should be done in autumn or early winter.

Pests

Diseases
