Growing Ficus from roots

One method to propagate new plants is from root cuttings. This is a thick piece of root that I cut off during the potting  process. I selected a root that showed some nice movment and planted the lower end into bonsai soil. I watered as needed and in 6 month’s time the end of the root sprouted new leaves and stems.

Not all Ficus will grow from root cuttings but one fig that does particularly well is Ficus tremula.

How to create a bonsai form a long and thin plant

It is not easy to create a bonsai from a long and thin piece of material. One way is to use some heavy wire and shape the limber material to your desires. Be creative and try many different shapes. Some will be exciting and some will be losers.

In this case a root cutting of Ficus ‘Mystery’ was used to create an interesting bonsai.

Root cuttings

Root cuttings are one of the easiest ways to develop a good bonsai from throw away materials. Repotting a fig bonsai is needed every year to 5 years depending upon growth, species, size of pot etc.

On removing some of the larger and more shapely roots the root is potted up with the root hairs in the soil and the cut end sticking out of the soil about 1-2 inches. After 2-6 months the end of the root will sprout new leaves and stems. Over time the new growth can be shaped to be an interesting bonsai. In addition most of the root can be lifted out of the pot to make a longer trunk.

Not all fig species will sprout from roots but natalensis is one that sprouts very easily.

Some steps in creating a bonsai from raw material

This is a young plant grown from a root cutting of a Ficus natalensis. The root cutting sprouted three branches.

To develop a new apex and create a better transition to the new apex, two of the sprouts were pulled together with electrical ties. A month or two passed and the ties were removed. The lower part of the fusion appears to be nicely grown together but the upper portion is not fused. So several new electrical ties were placed in areas adjacent to the old ties.

The ties were removed and the upper part of the fusion was not together. Some mild scars from the ties will be present for about 6 months. With growth they will disappear.

Two new ties were placed adjacent to the old ones and growth will be allowed to speed the fusion more completely

Some basic wiring was done to give the young bonsai a bit of shape

Ficus natalensis exposed root style

Ficus natalensis is one of my favorite species for bonsai. It has many characteristics making it suitable for bonsai. One, of these is how easily it is grown from root cuttings.

The images show one of mine that is only 2 years from a root cutting.

Some species of Ficus will grow from pieces of root. This is fortunate as repotting of figs is required every few years to maintain the health of the tree. At this time thick and unnecessary roots can be removed and rooted to form new plants.

A root cutting is shown from a Willow Leaf fig. The bonsai is now about 10 years old.
