AI Technical Summary
Existing bonsai pot designs require the installation of a bottom net to prevent soil from leaking through drainage and ventilation holes, which is a cumbersome process, especially when repotting multiple pots.
A bonsai pot with a bottom featuring a circular wall and multiple small holes that serve as a net substitute, eliminating the need for a separate bottom net.
Facilitates quick and efficient repotting by allowing the soil to be directly placed in the pot, improves drainage and ventilation, and prevents root rot by reducing water stagnation.

Abstract
Description
[Technical Field]
[0001] This invention relates to a bonsai pot that has multiple small holes in the bottom, eliminating the need to install a bottom net when repotting. [Background technology]
[0002] When repotting a bonsai, a mesh was placed over the drainage and ventilation holes at the bottom of the pot to prevent the soil from leaking out. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 7503879 Summary of the Invention [Problem to be solved by the invention]
[0004] There are always holes in the bottom of the pot for drainage and ventilation. A net is attached to the bottom to prevent the soil from leaking out through these holes. The number of holes varies depending on the size of the pot, but it was necessary to install netting in all of the holes. The work of preparing the netting and fixing wire and then properly attaching them to the bottom of the pots was a burden when there were a lot of pots. [Means for solving the problem]
[0005] This problem can be solved by a bonsai pot that has a bottom and a circular wall that extends from the bottom, and that has multiple small holes in the bottom.The multiple small holes act as a net, making it unnecessary to install a bottom net. [Effects of the Invention]
[0006] As described above, the structure is very simple, but there is no need to install a bottom net, and there are small holes to pass wire through to secure the bonsai tree, so you can quickly and smoothly carry out the series of steps of putting soil in the bottom of the pot, securing the bonsai tree, and then tilling the necessary soil into the pot.
[0007] As a standard practice, small holes for the fixing wire should be drilled in the four corners of the pot. Two is fine, but four is necessary to ensure proper fixing depending on the rooting condition. If necessary, small holes for drainage can also be used.
[0008] Many small holes are drilled in the bottom of the pot, which greatly improves drainage and ventilation, and prevents water from stagnating in the pot, preventing root rot caused by excessive moisture and promoting rooting and growth. [Brief explanation of the drawings]
[0009] [Figure 1] A plan view showing an embodiment of the bonsai pot described in claim 1. This drawing shows an example of a rectangular pot, but the same applies to bonsai pots of other shapes, whether flat or deep. [Figure 2] An example of the use of a bonsai pot that concretely illustrates the problem that the invention is trying to solve. [Figure 3] An embodiment of the bonsai pot described in claim 1. DETAILED DESCRIPTION OF THE INVENTION
[0010] After the pot has been shaped, it is left to dry for about seven days, and then several small holes are drilled in appropriate places in the bottom of the pot. At this time, small holes are drilled in the four corners of the bottom of the pot to pass the wire used to secure the bonsai tree through. The holes should be circular in shape. Glaze is applied to the outside of the pot, but not the inside. Sometimes the pot is left unglazed. The method of shaping the pot is the same as before. [Example]
[0011] Below, we will explain the examples with reference to the attached drawings. Figure 1 shows the side wall of the pot, which can be the same thickness all around. The thickness can be freely determined, but it is desirable to have a thickness that makes the bonsai stand out. For large pots, strength is required, so they will be thicker, but care must be taken to ensure the pot does not become too heavy.
[0012] Figure 2 shows the circular holes through which the wire used to secure the bonsai tree is passed. The holes are 2 to 4 mm in diameter. Four holes are better than two for securing the roots. Larger wire is used for larger pots, but wire of 4 mm or less can be used (except for extra-large pots). The location of the holes in the bottom of the pot is more important than their size. The key is to place them in the four corners of the bottom of the pot. Positions not close to the center of the bottom are more effective. If you need to secure the tree in the center, you can use the drainage and ventilation holes to pass the wire through. Furthermore, these holes not only allow for the wire to pass through, but also improve drainage and ventilation, preventing water retention at the bottom of the pot. The number of holes can be increased depending on the size of the pot.
[0013] Figure 3 shows small holes that replace the bottom mesh. The standard diameter is 3 mm. Square holes are acceptable, but circular holes are preferable for ease of construction. Holes smaller than 2 mm tend to become clogged with fine particles (finely broken down potting soil) contained in the potting medium. A 3 mm hole can be used in both large and small pots. The center of the pot needs to be at least 1 / 5 of the pot's bottom area. For a small pot with a diameter of about 9 cm, a cluster of five or six small holes is sufficient. The number of clusters can be adjusted according to the size of the pot, regardless of the pot's depth (height) or shape (round, square, rectangular, oval, ring-shaped, hanging, or quince). The effective area ratio is important. Clusters can be placed not only in the center but also in multiple locations along the bottom of the pot. However, in the case of extremely long and narrow pots such as rectangular pots, the planting position of the bonsai tree may be biased to one side, so it is easier to plant it on either side rather than in the center. If there are more small holes than necessary, drainage and ventilation will improve, but on the other hand, the pot may become too dry and difficult to manage.
[0014] There are also unglazed yakishime pots, and although you can apply glaze as you like, there is no need to apply it to the bottom of the pot. This is because it prevents drying and ventilation from the bottom. Generally, yakishime pots are often used for shoyaku bonsai, while glazed colored pots tend to be used for miscellaneous tree bonsai. The most important thing about pots is not only the size and shape, but also the depth (height). The depth (height) must be appropriate for the shape of the tree. Glaze, shape, and depth (height) are important aesthetic elements of the pot. [Explanation of symbols]
