Prune a Japanese Maple Tree

When and Where To Plant Japanese Maple Trees 
Maple trees prefer a part shade position which does not get the sun in the afternoon. They also do not like competition from other strong rooted plants and trees. To avoid the need for watering too often, choose a position that is moist but well-drained.

Planting should be done any time during the winter and early Spring months, October to December being the best months.

Planting is simple, dig a hole large enough to easily take the roots, place the tree in the hole and cover the roots with soil up to the surrounding ground level. Simple enough, but bear in mind a few points.

Don't add any fertiliser to the soil at this time because it may burn the roots. The tree should be planted to the same depth as it was in the pot. Having planted the tree, firm  down the soil using your boots to ensure the soil is in good contact with the roots - water well if the conditions are dry.
