Your twigs should have roots by now. It is now important to examine the roots to see if they are strong enough to support your new tree in soil. Roots should be 1. Plentiful, 2. between half as long or longer than the actual tree and 3. healthy with no black or broken spots.
If they do not show all of these signs i would suggest leaving the sapling in its water for a few weeks or a month longer to promote more root growth.
If your roots are long, strong and healthy, you may proceed with planting. One, decide whether you would like to put your new tree in a permanent Bonsai Pot, or a temporary plastic growth pot. If this is a first time tree i would suggest you buy a few cheap plastic pots and potting soil.
Placing The Tree In A Pot.
You are going to need a few things to do this, if you do not have them i suggest you buy them or find reasonable substitutes.
1. A pot large enough to contain the roots of the tree.
2. Enough potting soil to firmly cover the roots to the base of the trunk.
3. Small rocks such as pea gravel to cover the first half inch of your pot.
4. A thin wire mesh that will cover the bottom of your pot.
5. A Light training wire.
Once you have all of these, it is time to begin. Place the mesh wire in the bottom of the pot. Thread four pieces of training wire through the mesh and leave the ends sticking over the edge of the pot. Evenly layer your gravel over the wire mesh. Add perhaps an inch to two inches of soil. If this is a permanent pot decide where you would like the tree to be placed. In case of a plastic one you should probably stick with the center of the pot to allow maximum root growth on all sides.
Next you should create a small mound of soil in the tree’s new location. Carefully place your sapling on this mound , spread the roots evenly over the soil. Now take your wires and wrap them firmly but not tightly around the base of the tree. This is to hold it in place until it settles on its own. Now fill pot to the base of the tree trunk and water your new bonsai tree. Add more soil as it settles. I would advise placing the pot in a sink with around 2 inches of water and letting the soil soak all of the water up. Do not fertilize for at least a month after replanting to avoid upsetting the tree.
As this is a new tree, it is important to give it LOTS of water. Try to avoid keeping the soil wet at all times, but do not let it dry all the way out for at least the first two weeks. Your roots were grown in water and without careful re-adjustment to soil they will wither and die leaving you with a dead tree.
Should your tree die, Do not fear. There are always more twigs where that once came from. Remember, this takes patience, time, and a lot of love and care. Now enjoy your bonsai!
