Sow the seeds in nursery, if you want outdoor bonsai. Let the plant grow naturally for a year or two. You can then prune roots and shoots, wire it and plant in a container.

Growing Bonsai: A Beginner’s Guide
If you really want to create a bonsai yourself, you will have to spend a lot of years before you master this art form. However, if you are interested in bonsai and want to try your hands on bonsai, you can easily do so by following this step-by-step process.
Uproot a young plant and untangle the roots. In shrubs and trees, there are two types of root: taproot and feeder roots. Taproot is the main root that grows deep into the earth. Feeder roots are minor roots that grow around the taproot.
Prune the feeder roots, and little bit of taproot. Prune the plant few inches from the top to make it small.
Wrap the entire taproot with a wire. Wiring restricts roots from growing further. When root growth is restricted, growth will be focused around the trunk and shoots.
Prune the branches and pare the barks. Bend some of the branches to your desired inclination and taper with a wire. Tapering allows the bonsai to gain interesting angle. Be gentile while bending the branch.
Use mesh or screen to block the holes in the container. Screening prevents soil erosion. When you are growing a bonsai, you don’t allow the roots to spread, therefore, you use little soil. Therefore, one-third of the bottom part of the container should be filled with small stones. Place the plant that you want to create bonsai just above the stones and cover with soil. Soil should not be more than two inches thick. Finally, you cover the soil with stones. While preparing the potting soil add sand, clay and organic fertilizer.
You may use a stake to give support to the bonsai. You can remove the stake after few weeks.
Cover the soil with moss. Before you use moss, soak in water for 10 minutes.
Water the plant after transplanting. Remember, bonsai soils must always remain moist.
Be patient. Bonsai takes at least five years to exhibit a real beauty.
