Characteristics Ficus retusa

In this article, we will focus on the Ficus retusa (Ficus microcarpa L.) as it is one of the most popular and easy to find in specialized stores.

The Ficus retusa is a tree native to southern China and Southeast Asia, evergreen, that is, it keeps its green leaves all year round. Its foliage is compact, with leathery, oval, and shiny leaves.

Their flowers, mistaken for a fruit, are juicy and, as we have said, are called figs, although it is practically impossible to obtain them because the conditions are usually not suitable for their place of origin and the continuous pruning and trimming.

Care for Ficus Bonsai – Location

Due to its origin, it is a tree that does not like low temperatures, so in winter, if there were frosts (temperatures close to 32°F (0º C), it should be protected from the cold in a warm greenhouse, with plenty of light, but without direct sun, and at temperatures above 54 to 59°F (12 to 15º C). Special care should be taken with sudden changes in temperature because it is very sensitive to these and could lose all its leaves for this reason.

During the whole year, except in the moments of intense cold, its situation will have to be outdoors, partially shaded, obtaining this way that it recovers its green color and growth of the stems and leaves to a size more adapted to its cultivation as bonsai.

Care for Ficus Bonsai – Watering

To take care of the Ficus bonsai correctly, watering should be done thoroughly when the surface of the soil begins to dry out and avoiding both permanent waterlogging of the soil and leaving it completely dry.

In summer, a container can be kept in a tray with wet stones, always avoiding that the roots are in direct contact with the water, but this practice should never be maintained during winter.

It appreciates the spraying of its crown as it is a tree of tropical origin, but do it with great caution to avoid the proliferation of fungi and provided that you have treated the tree with a fungicide. In any case, if possible, avoid frequent spraying on the leaves.

Care for Ficus Bonsai – Fertilizing

Fertilize only during the period of vigorous growth and stop fertilizing when growth stops. We use this fertilizer on our bonsai (Order it here).

Do not forget that:

– We should NOT fertilize a repotted tree, we must wait for it to sprout.

– DO NOT water a tree grown outdoors after a frost or when there is a risk of frost.

Repotting Ficus retusa

For correct care of the Ficus bonsai, we must every 2 or 3 years repot, preferably in spring, before it sprouts when the temperature begins to reach 68°F (20ºC), with good soil that retains water and drains properly. However, if the tree is healthy, it can be repotted almost all year round.

Beware of lime content in the soil, as it causes yellow and weak leaves due to iron absorption problems. It should also be taken into account that soils with a lot of peat, due to the excess humidity, could produce diseases (fungi).

How to Prune Ficus Bonsai

Pruning the Ficus bonsai is very important for its care. Unwanted roots and branches should be pruned during repotting.

New shoots are pinched out during the summer at a distance of two leaves to compact the crown by branching the main branches.

It withstands drastic pruning well before spring and sprouts without difficulty from branches older than 2 years.

To reduce leaf size and encourage branching, leaves can be leafed out in late spring or early summer.

During pruning or defoliation, the branches will secrete abundant latex that will aid wound healing.

Wiring Ficus Bonsai

Branching by wiring should be done at any time of the year, but never immediately after repotting. The bark must be protected and care must be taken not to mark the wire.

The most frequent styles are moyogui or informal straight, multiple trunks, and on rocks.

Both during pruning and wiring of a bonsai, we must use the right tools to avoid damaging it. We recommend this kit for excellent care of the Ficus bonsai (Order it here).

Most Common Diseases and Parasites

Mealybug, red spider mite, and leaf fungus, although if properly grown, it is very resistant to diseases.

Leaf spots may appear due to fungus caused by spraying water on the foliage. This problem is easily solved with the preventive use of a fungicide or avoiding water spraying.

Another frequent problem, especially in poorly ventilated or indoor environments, with a dry and hot atmosphere, is attacks by mealybugs or red spider mites, which will cause progressive weakening. The treatment must be specific against the pest and constant over time until it is eliminated.
