Below: My Japanese black Pine “Pinus thunbergii” is with me since 1990 and was styled by me during a demonstration a year later. I remember the excited reaction of the students when I chopped off most of the top and turned the rest into a Jin (deadwood). It needed a repotting and some fresh soil to grow and strive in. Lifting it out of its pot was easy and that is a sure sign it needs to be repotted into fresh soil! All the long circling roots were shortened and a layer/ring of old soil and roots was removed working inwards and upward from the side leaving a hole in the middle for fresh soil. Pot by William Vlaanderen (NL). Height: 15-25 cm (Komono).
Below: The soil mount in between the exposed roots is left this time! water still penetrates it when I water so there is no problem for now! But next time that section needs more attention and fresh soil…but that’s for then!
Below: The tree basically grows over a month of soil, so when watering the water tends to run down fast and hard. So the chance that this fresh soil will be flushed away is imminent…so to prevent this I mixed some Kato with very fine Akadama and Akadama dust with some water to make it into a more malleable paste!
Below: That thick paste is then applied over the soil and pushed down to make a nice sloppy month where water can run down without taking the fresh soil along with it. I now only have to make sure that I water enough and have to check every time if the water runs through the hole in the bottom! In a month or so when the new soil is more settled the layer of Kato will be simply scraped away.
More later on this little tree!
