Bonsai is an ancient Japanese art form that involves growing miniature trees in containers. One of the essential aspects of bonsai is finding and collecting suitable trees to train into beautiful, aesthetically pleasing shapes. The traditional method of collecting bonsai stock is through yamadori, which refers to the act of collecting wild trees from their natural habitats.

However, with urbanization taking over many parts of the world, finding suitable trees for bonsai cultivation has become increasingly challenging. This predicament has given rise to a new type of yamadori called urban yamadori.
Definition Of Urban Yamadori
Urban Yamadori refers to the practice of finding and collecting small trees that grow in urban settings such as parks, abandoned lots, or even along roadsides. These are often considered “weeds” by most people, but they possess unique qualities that make them suitable for bonsai cultivation.
Unlike traditional yamadori collected from remote mountainous areas, urban yamadori can be found easily in most cities around the world. They are often available all year round and provide an excellent alternative source for those who cannot access traditional yamadori.
Brief History And Origin Of The Practice
The practice of using urban yamadori for bonsai cultivation started in Japan during the 1980s when people began exploring new ways to acquire suitable stock for their bonsai artistry. Urbanization was already rampant in Japan at this time, making it increasingly difficult to find traditional yamadori.
As a result, passionate bonsai enthusiasts began exploring their cities’ streets and parks looking for suitable specimens that could be trained as bonsai. The trend soon spread globally with collectors visiting various metropolitan areas around the world searching for unique plants that would make excellent additions to their personal collection.
Today, urban yamadori has become a popular practice among bonsai enthusiasts worldwide, thanks to its accessibility and the unique characteristics of the trees that make them ideal for bonsai cultivation. In the following sections, we will explore how to find and collect urban yamadori, the different types of trees suitable for bonsai cultivation, as well as the challenges and benefits of using urban yamadori over traditional stock.
The Art Of Urban Yamadori
Techniques For Finding And Collecting Urban Yamadori
Urban Yamadori collection can be a challenging task, but when done correctly, it can yield some stunning results. The first step is to identify the potential tree’s location. Pay attention to the trees growing along the roadside, abandoned lots, and even trees that are growing in peoples’ backyards.
Understanding the local laws is essential as some areas prohibit collecting from public property or have specific regulations regarding private property. After identifying a potential specimen for collection, it’s important to examine its health and overall aesthetic appeal.
Look for any damage or signs of disease as this could impact its ability to survive during transplanting. In addition, observe the tree’s shape and form; you want a tree with interesting features that will make for an appealing bonsai.
Tools And Equipment Needed For Successful Collection
Having the right tools and equipment is crucial when it comes to successful urban yamadori collection. A sturdy pair of boots or shoes with good traction is essential since you will be walking on uneven terrain.
Other necessary gear includes gloves, safety glasses or goggles, and pruning shears. A digging tool such as a shovel will assist in removing soil from around roots while minimizing root damage upon removal from the ground.
A hand saw may also come in handy if larger branches need trimming before transport. Transporting your collected specimens can be facilitated using a tarp or canvas cloth to minimize shock during transportation.
Tips For Selecting The Best Specimens
Selecting suitable specimens requires an understanding of what makes a healthy tree suitable for bonsai cultivation – young trees with small leaves being preferred over older trees with larger leaves which are more difficult to reduce in size over time. Some characteristics of desirable specimens include tapering trunks (slimmer at top than base), interesting bark texture and color variation, trunk movement, and suitable branching structure.
It’s important to note that smaller specimens will have a higher survival rate in the planting process. When selecting specimens from public areas, be mindful of conservation efforts in place and avoid taking specimens from endangered species of trees.
Also, don’t take more than necessary or significantly damage the environment when collecting. By following these guidelines, you can successfully collect healthy urban yamadori trees that will thrive as bonsai.
Types Of Urban Yamadori Trees
Common Species Found In Urban Areas
One of the great things about urban yamadori is the variety of trees available for collection. Some of the most common species found in urban areas include maples, elms, junipers, pines, and cedars. However, depending on your location and surroundings, you may also find more unique species like magnolias or even fruit trees.
When searching for urban yamadori, it’s important to keep an eye out for any tree that catches your attention. Don’t limit yourself to just looking for traditional bonsai species – some of the best specimens can be found in unexpected places.
Characteristics That Make Them Suitable For Bonsai Cultivation
What makes a tree suitable for bonsai cultivation? There are a few key characteristics to look for: – Small leaves: The leaves on a bonsai should be proportional to its size.
Trees with naturally small leaves are ideal candidates as they won’t need as much pruning. – Fine branching: Bonsai trees need to have fine branching patterns that can be trained and shaped over time.
– Interesting trunk movement: The trunk should have interesting movement or character to create visual interest in the final design. – Tolerance to pruning: Trees that can handle heavy pruning without dying back or suffering long-term damage are ideal candidates.
Many urban yamadori trees have these characteristics naturally or can be easily trained into them through proper care and maintenance after collection. It’s important to choose specimens that are healthy and have good potential for future growth and development.
Bonsai Styles Best Suited For Urban Yamadori Trees
There are many different styles of bonsai, but some lend themselves better to urban yamadori than others. Some styles that work particularly well include: – Informal upright: This style features a straight trunk with branches that gradually curve upward.
– Literati: A more dramatic style, literati bonsai have twisted and contorted trunks with sparse foliage. – Cascade: The cascade style features a trailing branch or branches that extend downward from the overall shape of the tree.
These styles work well with many urban yamadori specimens because they allow for the natural growth patterns of the tree to be accentuated and highlighted. It’s also important to keep in mind the size and shape of the original tree when selecting a style – some specimens may lend themselves better to certain styles than others.
Challenges And Benefits Of Urban Yamadori Collection
Environmental Factors To Consider When Collecting From Urban Areas
Urban yamadori collection has both benefits and challenges that come with it. One of the major challenges is navigating the environmental factors presented by urban areas. When collecting from urban areas, there are several things to consider in order to ensure that your tree will thrive once it has been collected.
Firstly, air pollution is a major concern when collecting from urban areas. Trees growing in polluted environments can absorb harmful chemicals through their leaves and roots, which can cause health problems for the tree over time.
It is important to avoid collecting trees from heavily polluted areas such as busy roads or industrial sites. Secondly, soil quality is another important factor to consider when collecting from urban areas.
Many trees growing in cities are planted in poor quality soil or even in confined spaces such as sidewalk planters. This can lead to stunted growth and other health issues for the tree.
It’s important to consider any potential damage caused by wildlife or human activity. Trees growing near buildings or sidewalks may have damaged roots due to construction work or foot traffic.
Advantages Of Using Urban Yamadori Over Traditional Bonsai Stock
Despite these challenges, there are many advantages of using urban yamadori over traditional bonsai stock. Firstly, urban yamadori often have more character and unique features due to their exposure to various environmental factors such as wind and pollution. Secondly, because they are often unwanted plants living in confined spaces like city streets or abandoned lots, they are readily available for collection with little cost involved.
This makes them an affordable option for bonsai enthusiasts who may not have the financial means to purchase traditional bonsai stock. Furthermore, cultivating urban yamadori helps improve the overall health of city ecosystems by removing unwanted or invasive plants.
This can have a positive impact on the environment and urban biodiversity. Using urban yamadori for bonsai cultivation is a sustainable and environmentally friendly practice.
Instead of relying on imported or artificially grown bonsai stock, collecting from urban areas reduces the carbon footprint associated with transporting trees long distances. Overall, despite the challenges that come with collecting from urban areas, using urban yamadori for bonsai cultivation has many benefits both for the health of individual trees and the environment as a whole.
Cultivating Urban Yamadori Bonsai
Steps To Take After Collection
After successfully collecting your urban yamadori tree, it is important to take certain steps to ensure its survival. First, remove any dead or damaged branches and foliage.
This will help the tree conserve energy and focus on growing new healthy shoots. Next, trim the roots carefully, being sure not to damage the main root system.
Repot the tree in a well-draining soil mixture that includes a blend of organic material such as peat moss or compost. It is vital to monitor your newly collected urban yamadori carefully for the first few weeks after collection.
The tree may experience slight shock due to changes in environment and soil composition. Be sure to keep it properly watered but do not overwater as this can lead to root rot.
Techniques For Training And Shaping The Tree
Once your urban yamadori has acclimated to its new environment, it’s time to start training and shaping it using various techniques such as wiring and pruning. Wiring is used to guide branches into desired shapes while pruning helps direct growth by removing unwanted growth points.
One technique that works exceptionally well with urban yamadori trees is clip-and-grow training. This involves clipping off new shoots at their base, causing them to grow back thicker with more branching.
Over time this technique can create a much fuller canopy of leaves and create interesting shapes. Another popular technique for shaping bonsai trees is Jin (Deadwood) creation which involves stripping away bark from small areas on the trunk of a tree using tools like jin pliers or carving tools then allowing it dry out naturally before sealing with lime sulphur.
Maintenance Tips For Keeping Your Urban Yamadori Healthy
Maintaining proper care of your urban yamadori is key to ensuring its long-term health. It is important to keep your tree in a location where it can receive adequate sunlight for its species.
Most urban yamadori trees require a lot of bright indirect light, so consider placing them near windows or under grow lights. Watering is also crucial to keeping your tree healthy.
Be sure to water it regularly, but not too frequently as over-watering can lead to root rot. Use a well-draining soil mixture and ensure proper drainage from the pot.
Fertilization is equally important for your urban yamadori’s growth and health. Use a good quality balanced fertilizer during the growing season and reduce fertilizing during winter when the tree is dormant.
In addition, be sure to monitor your tree for pests and diseases like spider mites or scale insects which can damage or kill your tree if left untreated. Use organic pest control methods such as neem oil sprays or predatory insects if possible.
