El bonsai 盆栽 is a traditional Japanese art based on growing miniature trees in pots, a method that allows us to enjoy the beauty of nature on a small scale. The word itself literally means "tray" (bon) and "cultivate" (sai). As you delve deeper into this fascinating world, one of the most important features to consider is the bonsai sizes, which determine how they are classified and how much attention they require in their care.
Bonsai size classification recognizes that these trees can range from a few centimeters to remarkable heights of 130 centimeters or more, although generally, a bonsai should not exceed 100 centimeters to be considered as such. The different sizes and their relevant characteristics will be described below.
Bonsai Size Classification
Bonsai trees are generally classified by height. The commonly accepted classification is presented below:
- Shito or Keshitsubu: This is the smallest category of bonsai, measuring less than 5 centimeters. These are extremely difficult to care for and require special techniques to maintain their humidity.
- Mame: Bonsai trees measuring between 5 and 15 centimeters. This size is defined as "any bonsai that fits in the palm of a hand" and also requires constant attention to watering and fertilizing.
- Shoin: Bonsai trees under 25 centimeters tall. The Japanese term "shohin" means "small," and this category has become popular due to its ease of handling and the small space it requires.
- Komono or Kotate Mochi: These bonsai range in height from 15 to 40 centimeters. They are the most popular category among hobbyists, as they are more robust and less delicate to handle.
- Chumono: This refers to bonsai trees measuring 30 to 60 centimeters. This size is also quite popular and can be handled with one hand, making them accessible to many growers.
- Omono: This category includes bonsai trees measuring between 60 and 120 centimeters. They are considered large bonsai, and transporting them generally requires two people, given their size.
- Hachi-Uye: A bonsai tree measuring more than 130 centimeters, although its classification is debated. Some specialists do not consider it a bonsai in the traditional sense, as it is commonly seen as a shaped tree resembling a bonsai.
It's important to note that the classification may vary slightly depending on the bonsai school you consult. However, these categories represent a solid foundation for understanding the different bonsai sizes.
Care Considerations for Each Size
The care of each bonsai varies considerably depending on its size. Here are some care considerations based on the classification:
- Shito: They require frequent watering and a carefully controlled substrate, due to their small size and the limited water retention capacity of their pots.
- Mame: Similar to shito, these bonsai need to be in a protected environment, ideally in semi-shade, to prevent the substrate from drying out too quickly.
- Shoin: Although they are somewhat larger, their handling is still delicate, and they require constant watering control and a substrate that maintains good moisture.
- Komono: They require less attention in terms of watering, thanks to their larger pots that retain moisture better.
- Chumono: This size allows for a variety of species, and its care is more flexible, since its pots can retain more water.
- Omono: Bonsai in this category tend to be more robust, but require special attention during transport, as well as in general care.
- Hachi-Uye: Because they are larger trees, their care is considered more like that of a garden tree, and their transport may require special equipment.
Knowing the care required for each type of bonsai is essential to ensure its long-term growth and health. As the size of a bonsai grows, so does the care it requires.
Aesthetic and Artistic Implications
In addition to size classification, bonsai is considered an art form. Each bonsai, depending on its size, can represent a different view of the natural world. Smaller bonsai allow for a closer view and detailed of nature, while the larger ones can evoke a feeling of majesty and presence.
Bonsai exhibitions often categorize bonsai by size, and each category has its own aesthetic characteristics that can influence how each tree is presented. the king, for example, can be displayed in groups, creating compositions rich in visual effectsWhile a omono could stand out as the focal point of a solo exhibition.
Combining size, species and technique contribute to the appreciation of bonsai as an art. Experienced growers dedicate years of effort to achieve an aesthetic form that represents the perfect harmony between the tree and its surroundings.
The beauty of a bonsai lies not only in its form, but also in the story each one tells and the effort that has gone into making it grow, develop, and eventually become a living masterpiece.
