Bonsai tree

Part 4 of 5

Once the tree and pot are ready, it’s time to put them together. For starters, the pot gets a drainage layer of pumice. If the pot were much thiner or the climate warmer I might forego this step, but I’ve found my maples do well with it.

Pumice drainage layer

After spreading out the drainage layer, I add my decidous bonsai mix – mostly akadama with pumice, lava and charcoal. I typically form a mound in the center of the pot when I pour in the mix to help prevent air pockets from forming when the tree is set. If the base of the rootball is concave, this becomes particularly important.

Next comes one of the most imprtant parts of the whole process – seting the tree. Although it’s not a very technical maneuver, it requires care to make sure the tree ends up in the right spot. This time Boon set the tree while I held the pot. We then checked the location of the tree, the height of the rootbal, the tilt of the tree, and the front. After making a few minor adjustments, it was time to tie the tree into the pot.

Setting the tree

There are many ways to secure a bonsai in a pot. The goal – to prevent the tree from moving to avoid damaging new roots. The photos below depict a basic technique that does a great job of holding trees in place.

Before I attach the first two wires to each other, I add a tail – an extra piece of wire that will help me make my final connection as I work my way around the rootball.

Adding a tail

I then pull the first wire to a location above the spot where the second wire comes through the drainage hole. I make a few twists by hand and continue around the tree until it’s time to connect the final wire with the tail I attached to the first wire. This final connection requires pliers.

Securing the tree

A subtle but important trick to using pliers: pull, then twist. If you’ve repotted at Boon’s, you’ve heard the phrase before. The idea is to pull the wires taught, then slightly release the pressure as you make the twist. Doing this helps one avoid breaking the wire.

Proper plier technique: pull

Then twist

When done well, using the pliers for this union tightens all of the other connections. It’s a fast and effective way to secure a tree.

Before adding more soil, I trim any extraneous wire. Hopefully there’s not too much. If there is, you might hear Boon say “bimbo,” but not as in “air-head.” He’ll be happy to explain.
