Bonsai Styles: Root-Over-Rock – Sekijoju

by Rocky Mountain Bonsai Society Member Stefan Rausch on May 8, 2013

 

In this style the rock is at the base of the trunk, with the roots exposed to varying degrees as they traverse the rock and then descend into the soil below. This style takes time to develop, the roots of the tree must be growing on the rock long enough to grip and callous to swell and give the appearance of age. This style allows us to create an image that we see quite often in nature, allowing us to really attract the viewer to our image.

Advantages of Sekijoju

Are that not only are you displaying a Bonsai but also an image of landscape. The roots flowing down throughout the rock give an impression of age and struggle. Bonsai that seem as if they are taken right out of their natural landscape and put into a pot are some of the most appealing images, and Sekikoku allows us to convey that image.

Disadvantage of Sekijoju

Is the ability to find a rock that really matches the image you are trying to convey. A lot of times people choose rocks that are far too small for the final image they are creating. I have seen many trees that the roots have almost completely engulfed the rock and it looks a little strange. The key is to pick a rock much larger then you would really think, allowing the tree to grow into the image over time. Remember we are thinking 10-20 years down the line with our bonsai.

All types of trees can be applied to this style.

  • Trident Maple (Acer Buergerianum)
  • Beech (Fagus sp.)
  • Crab Apple (Malus sp.)
  • Pomegranate (Punica granatum)
  • Ponderosa Pine (Pinus ponderosa)

 

Stefan Rausch was born and raised in Colorado, growing up hiking, hunting and fishing dominated most of his time ingraining his love for the Rocky Mountains. He started working with all types of plant material at an early age working his way up to a full time position in horticulture at one of Colorado’s most premier country clubs. His brother saw this interest and soon invited him to a local bonsai show, this is where for the first time he saw the possibilities and artistic expression of bonsai and what could be done with local Rocky Mountain material. He is truly passionate about the progression and future of Bonsai as an art form, especially here in the United States. Stefan has been lucky enough to learn first hand from some of the best Yamadori collectors and Bonsai Artists such as Larry Jackel and Harold Sasaki.
