The Acer genus includes more than a hundred species, many of which have cultivars selected for their decorative value. Some of the best known and most widely used are:
- Acer palmatum (Japanese maple): Native to East Asia, it is famous for its palmate leaves and its spectacular color changes in autumn. There are subspecies such as Acer palmatum subsp. matsumure (large leaves), palmatum (small leaves), and amoenum (intermediate). Among the Japanese maple, the following stand out:
- defoliation: carmine red leaves in spring, green in summer and brown in autumn.
- arakawa: stands out for its rough trunk and green leaves that turn yellow in autumn.
- Katsura: yellowish green leaves with orange tips and reddish edges.
- Aoyagi: lime green in summer and yellow in autumn, bright green bark, ideal for visual contrast and for bonsai.
- Acer platanoides (Norwegian maple): Large size, rounded crown, palmate leaves and a yellow or reddish autumnal hue. It withstands cold and pollution well, and is used in avenues and parks.
- country maple: Hardy, smaller tree, ideal for small gardensGreen leaves that turn golden in autumn.
In addition, there are other species notable for their specific colors or shapes, common in themed gardens or small collections of maples.
Ornamental value and landscape uses of maple
The main attraction of the maple lies in its changing and spectacular foliageDuring spring and summer, its leaves appear a deep green or, in certain varieties, reddish or purple hues. But it's during autumn that it truly shines, transforming gardens and parks with explosions of color.
Ornamental uses of maple:
- Garden tree as a central element or in decorative groups.
- Low borders and hedges in the case of small species.
- Bonsai, thanks to the ease of shaping its shape and attractive foliage.
- Growing in pots for terraces or patios, especially in varieties such as Aoyagi.
- Urban alignments (Norwegian maple, field maple) for their resistance and shade.
Maple also has ecological importance, as its flowers attract pollinating insects, and its fruits (samaras) are a food source for birds and small mammals. In some regions, certain species are prized for their syrup production or honey value.
Maple flowering and fruiting
Although the ornamental value of maple flowers It is usually secondary to the foliage, many species produce small clustered flowers in clusters, in shades of white, red, or purple, during the spring. These flowers are delicate and can go unnoticed, but they contribute to the biodiversity of the environment. The characteristic fruit is the double samara, a type of wing that when mature is easily dispersed by the wind.
In species such as the Japanese maple, the flowers have five reddish sepals and five white petals, grouped in small cymes that usually appear before or together with the new leaves.
Essential care for maple cultivation
Maple is a rustic tree and resistant, but requires certain care to reach its maximum ornamental splendor:
- Location: Prefers lightly shaded or filtered locations, as intense direct sunlight can damage the leaves of delicate species. In cool or temperate climates, it tolerates full sun exposure.
- IrrigationKeep the soil moist, with regular watering but not overwatering. In pots, ensure optimal drainage to prevent root rot.
- LandThey thrive in fertile, slightly acidic or neutral, cool, and well-drained soils. They do not tolerate extreme drought or compacted soils.
- Temperature: They tolerate light frosts well and even very low temperatures in certain species such as Aoyagi (up to -15ºC), although prolonged frost can be harmful.
- SubscriberUse balanced fertilizers, preferably for acid-loving plants, during the growing season. Avoid fertilizing in autumn and winter to prevent shoots that could be damaged by the cold.
- Pruning: Perform formative and maintenance pruning in late winter or early spring, removing damaged or disordered branches.
Some species, such as Acer palmatum AoyagiThey can be grown both in the ground and in pots and are suitable for terraces or balconies. They should be protected from strong winds, which can tear the leaves, and humidity should be carefully controlled in containers.
Common Maple Diseases and Problems
Maple is generally hardy, but can be affected by some diseases:
- verticillium wilt: A fungus that causes wilting and leaf drop. It's important to remove and destroy affected branches and improve drainage.
- Root rot: Due to excess water or poor drainage. Avoid puddles and use porous substrates.
- Leaf spots: Caused by fungus or sunburn. Improving ventilation and adjusting light exposure helps prevent them.
Preventive surveillance is recommended, as is immediate action to address any symptoms. Watering and sun exposure should be adjusted to prevent stress on the tree.
Benefits and contributions of maple to the environment
Beyond its visual spectacularity, the maple provides numerous benefits:
- Regulates temperature and provides shade in gardens and urban environments.
- It contributes to biodiversity by providing refuge and food for local fauna.
- In certain species, its flowers are melliferous, valued for honey production.
