The picture was taken directly after the last reduction of height and I started feeling that the work was beginning to pay off. Also during about a year I had applied a clamp in an attempt to straighten out the bend in the lower part of the trunk.
I gave a lot of fertilizer and as a soil mix I was using cat litter and ordinary houseplant soil in a 50/50 mix. The cat litter works very well since it retains lots of humidity without making the soil wet. Unfortunately, it decomposes after about two years.
