The clump I started last year has fused at the base in one season. I started out with five cutting thru one hole with nary any space for the cutting so fusion was a no brainer. Now this year I need to bulk up the tree at the base as well as start to come up with some kind of trunk out of the mass of cutting I poked thru the hole.
This is the tree today before the work. All of the trees doubled in size, which is not to say much since they were as big as a match stick and now they are as big as a pencil.
The basket had been sitting on the soil in one of my planters so that the weekly sprinkler would water it. The roots grew right out of the planter and into the ground.
It wouldn’t come out of the pot so I had to cut all the roots flush with the bottom of the basket.
Once it was unpotted I was able to wash away the soil and really look at what I had. The roots had grown over the edge as I suspected they would and they were about half the size of the trunk. I was missing a few roots on one whole side though.
I cut back the large roots to the edge of the tile. I might have wished I cut them a little shorter as next year I may have to do this all over again. Also take a look at the tree at 9 o clock and three. the both have a bud down real low. Both buds face inwards. Since I started this project with all the trees thru the tile, I have no central tree to use as a main tree with a flared base. My original intention was to make a clump style but starting with trees all the same size is probably not the way to do it.
Here is a nice view of those two buds.
Here are the two trunks chopped back to the buds. I seal them well and they should grow very hard this year.
This clump is also grown out in pure agricultural pumice. This is natural volcanic pumice and stark white and a little smaller than the growstones. I turn the tree over and pack the bottom roots full of pumice using a chopstick. Since I didn’t cut the rim off the saucer when I did this, there is a pocket of sorts that the original roots grow in. I just need to make sure I have plenty of soil in there with no dry spots or cavities with no soil to dry the roots before they grow.
It is turned into the pot and then I refill the top with last years medium which is my base mix of half lava half pumice.
These are close ups of the two trunks that will be possible candidates for keeping for a single trunked tree depending on how they grow this year. Both have kionyl type sealer on them.
