The Japanese maple tree (Acer palmatum) is considered one of the most distinctive and attractive ornamental trees with its complex lobed leaves and colors graduating between green, deep red, and bronze. Successful care involves selecting the appropriate variety, planting in organic-rich, well-drained, and slightly acidic soil, and protecting it from harsh midday sun and strong winds. It is important that the planting hole matches the depth of the root ball to prevent rot, while relying on regular pruning in late winter. Research from Oregon State University indicates that Japanese maples tolerate temperatures down to -20 degrees Celsius, and that using organic mulch and maintaining soil moisture can reduce the tree's irrigation requirement by up to 30%.
