I have some Ficus Benjamina cuttings that rooted in water mixed with some liquid rooting hormone. For a long time I was thinking about what new design should I approach with these in order to do something different. As I visited Greece this summer, I collected some interesting stones that inspired me for this project, so I started building my design as soon as I returned. So, the new project was established: root over rock of Ficus Benjamina. Usually, all the bonsai masters all over USA and Japan teach that root over rock projects start with adding wet sphagnum moss around the roots till these are established and reach the soil. However, I have a different approach. As usual, we learn from mistakes or from coincidences. I have a root over rock project with a Lonicera tree. At that moment, the rock was too large and the roots of the tiny tree did not reach the soil. I was in a hurry to leave so after I fixed the tree to the rock, I wrapped the rock with the small roots with an old t-shirt that I watered just enough to keep the roots wet. The idea was to continue the next day the work with sphagnum moss. Next day I was busy again, and then the next day thesame … so the tiny tree’s roots on the rock remained wrapped with the t-shirt. I just added water daily to make sure that the roots are wet. In a few weeks, I saw an increasing vigor and the tree started developing new foliage  and normally new roots. By the middle of summer all the roots reached the ground and due to the t-shirt that was tight to the rock, these ran in the close proximity of the rock, following its shape. Today they look awesome, these are thick, shaped just like the rock and again, due to the t-shirt it did not develop any feeder roots, tempted just to grow fast down to the ground. This is how I developed my approach and I will share it with you all as follows.

The rocks that I have collected have many crevasses and these look just perfect for such a project. 

These are the rocks that I have collected. They are pretty tall, so I had to fix them to the pots. In the pictures below, you can see the slim pots that I considered to use in order to put the accent over the tall rocks and their future trees.

In order to fix the rocks to the pot, I found the best place in the pot that advantages the design. I drilled two holes that will allow the wire to pass via the bottom of the pot and the lower side of the rock to make sure there is a strong bond between the ceramics and the rock.

In the same way, I drilled a hole in the rock and cut away the bottom side of the spikes of the rock to ensure a straight contact surface between the pot and the rock.

After fixing the rock to the pot, it looks like in the pictures below. Now you can understand why I chose a slim pot and why tying it strongly to the pot is mandatory.

In the same way, I fixed the second rock to the second pot. There are several good reasons why you have to make sure that the rock is not moving, the roots can grow with no danger of braking and when building the upper part of the design you will have a good and solid base to work.

The next step was to fix the trees to the rocks. For this, I use natural rope because it will keep the tree in position for a period of time till it will develop new roots to establish the position and in a few months it will rot away. Using a chopping stick I also arranged the roots in the desired places. When placing them, always think of the way where these will grow as the roots are tempted always to grow downwards and try to find the shortest path to the soil.

I added the new soil and the roots that were long enough, I placed them already to reach the surface of the soil. I know that as soon as I will start watering the trees, the roots will find their way into the soil. If you push them down into the soil there is always a risk to harm them with the force you use to push them in.

In the end, I added parts of another old t-shirt, tie it with the same natural rope and add some soil mix in the areas where the distance between the rock and the textile remained too big. In case you consider that the textile will dry out too fast, you can use a plastic transparent bag or kitchen wrapping plastic to create a closed environment that will retain the water. However, you have to leave the upper part opened to be able to water and to allow oxygen circulation.

I hope that by Spring of 2019 I will be able to remove the textile and give you all an update on the two Ficus designs. Normally, by then, the roots should have reached the ground already. Just as last mention, I already stated this in other posts. I do not like using sphagnum moss because it tangles between the roots, it never rots away and it encourages developing feeder roots close to the rock and not pushing the elongation of the roots down into the soil.

This is my approach that I found to work quite fine, so be my guest and try it on your own.

Thanks for the visit,
