The Japanese maple has been a favorite of Japanese gardeners for centuries. Over the years many different cultivars have been bred and now there in excess of 1,000 different varieties. However, some of these do not travel well and at present there are around 100 - 150 different cultivars available elsewhere. The variety of these in size, color and shape is sufficient for most people to choose a plant for their requirements.
There are four main factors to consider when planning where to plant a Japanese maple tree. These are sunlight, water, wind and ensuring that there is room to grow. These apply to trees that are being planted outside as well as those that are being potted for either outdoor or indoor use.
Sunlight
As a rule, the maple likes the sun, especially in the morning, but not excessive sunlight. If you live in a sunny, hot area then you will need to consider some shade for the tree. For larger plants this could be other trees or buildings. For smaller trees you may need to consider constructing a shade system.
Water
Japanese maples like plenty of water but it must be a well drained area. If you have a pond or river nearby then this is a good indication that you will be okay. Overwatering and poor drainage is a key problem with many maples.
Wind
Surprisingly the wind plays quite an important part of where to plant your maple. The maple has a shallow root system and too much wind will dry out the soil too quickly. Also the wind carries bacteria which can affect the health of your tree. High winds can also affect growth patterns so you may need to consider staking the tree to help it grow straight.
Room to grow
Because the Japanese maple has a shallow root system, planning for room to grow is not too much of a problem. Allowing the same room as the expected upper spread of the tree should be sufficient. For potted plants allow 2 - 3 times the area of the current root system, this should be good for a couple of years.
The important point to note when you plant Japanese maple trees is to recognize their original habitat. They are mountain trees and enjoy well drained soil, plenty of water, are well adapted to differences in temperature and enjoy the company of other trees and plants for protection.
