How to Choose Rocks for Landscape Bonsai

Rock for landscape bonsai

Generally, Chinese penjing (penjing is bonsai in Chinese) can be categorized into three types: tree penjing, landscape penjing (Shanshui Penjing, 山水盆景 in Chinese), and water-and-land penjing (shuihan penjing, 水旱盆景 in Chinese). Unlike tree penjing, which has dwarfed trees be the core and only element in the pot, landscape penjing and water-and-land penjing have rocks playing a big role as well. Indeed, in landscape penjing, the rock rather than the tree is the central focus of the scene.

Hence, rock plays a big part in Chinese penjing. While we have different sets of criteria when selecting suitable rocks for different penjing, some general rules always (or almost always) apply. And here are some general guidelines for choosing rocks particularly for landscape penjing with mountain or cliff scene.

Rock Type

Many kinds of rocks are suitable for penjing, as long as the rocks are strong and won’t break apart easily. In Guangdong province, landscapes made from Ying Rock are common. Rock pieces are piled in an ingenious manner to create an appearance of both grandeur and elegance, or to effect rock formations which either thrust into the sky or lie across the container and stretch toward the horizon.

Rock Shape

When we are looking for a nice piece of rock for our landscape penjing, we always try to find one that is in the shape of an inverted (or upside down) triangle. This is especially important for landscape penjing of cliff scene. This is because it is easier to create a steep, dangerous-looking cliff with rock that is in the shape of an inverted triangle than one in a boring, broad, flat shape.

Cracks on Rocks

Rocks with vertical lines and cracks are preferred over rocks with horizontal lines and cracks. This is because the branches and roots of our bonsai trees can develop and grow better within the vertical cracks, and grip the rock along the vertical cracks more securely.

Rock Color

Usually we use white, cream, black, gray, brownish red, or a mix of these colors. Just remember don’t use green rock for it may cover up the beautiful foliage of our bonsai tree.

    Very good suggestion. But how you made the base for the rock to stand properly without support.

  3. Sandy Sandy says:

    Kamini,

    Can you see the piece of concrete at the base of the rock in some of the photos of this post? We make them after we have done with all the cutting and shaping of the rock. Maybe let me write a post explaining how this is done later when time allows.

    Happy Bonsai!

    Thanks for replying, I will be happy if you write in detail.

    Where can you buy these rocks?

  6. Sandy Sandy says:

    I bought mine in Yingde, China. There are some available in Guangzhou, China too. It’s more convenient for me to go to Guangzhou, but there are less choices and more expensive.

  7. Paul says:

    It all depends on where you live I guess but just a quick walk in the forest and once I start searching, it’s amazing at the rocks you can find…for free… And also, it makes a great family activity whaen going rock hunting!

    Thanks for this post Sandy

    You mention cutting and shaping. Do you use hand tools? Power tools? Wondering what you use….nice photos…especially rock 05 pictured above. I’m looking around for one like that but may have to move over to cutting and shaping techniques. Keep up the excellent work Sandy.

    Gr8 inspiring job..

  15. sanjay says:

    Hi Sandy, your posts are very informative and useful. You’ve used cement to make the base of rock.This is pure cement or mixture of cement and sand i.e. mortar? If it is a mortar,then what is the ratio of cement and sand?
    Regards……

    I just went to my local rock/ landscaping company.

    They had.a nice collection of lava rock. I chose a piece and took home a mason saw blade.

    I promptly turned a watermelon sized chunk of lava into four nice pieces I’ll use for my root over rock etc. the mason blade was 35 bus for my skill saw (7″).

    I’ll post more later…
