Care of the tree Acer palmatum or Japanese maple

In the Sapindaceae family the genus Acer is classified, consisting of about 160 species of trees and shrubs from temperate regions of Europe, Asia and North America. Some species are: Acer palmatum, Acer obtusifolium, Acer negundo, Acer campestre, Acer sempervirens, Acer platanoides, Acer pseudoplatanus.

Common names: Japanese maple, Palmate maple, Red emperor maple, Smooth Japanese-maple. This species is native to Eastern Asia.

They are small deciduous trees with an elegant bearing and a rounded crown that reach 10 meters (32.80 feet) height. The most interesting are its palmate leaves (with 5 or 7 lobes) that can be light green, purple or reddish depending on the variety; in autumn they acquire reddish or yellowish tones. The flowers have no ornamental interest.

They are used in parks and avenues or in gardens as isolated specimens or in shrub groups; It combines very well with specimens of the genus Amelanchier, Ilex and Malus. They are also used to create bonsai.

The Acer palmatum can be grown in full sun (in cold climates), semi-shade (in Mediterranean climate) and shade exposures. It is able to tolerate frost and live in subtropical climates.

Soil can be a mix of garden soil with peat or leaf mulch and sand to drain well. Planting in its final place is done in early spring.

Water regularly throughout the year so that the soil is always a little damp as they do not tolerate drought.

They do not need pruning but old or dry branches can be removed.

Fertilize every 2-3 months with a fertilizer rich in nitrogen and potassium.

Palmate maple can be attacked by mealybugs and aphids if they suffer from drought and by some caterpillars that devour their leaves.

Although they can be propagated by grafting or layering, they are not easy systems; it's advisable to purchase the new specimens in nurseries, plant shops or in garden centers.
