Ficus retusa

Family

Origin

From the Greek “sykos” meaning fig.

Ficus retusa

Characteristics

It is a tropical evergreen leaf tree. Appreciated for its high resistance and the growth of air-roots giving great character.


Place

Ideally in a Mediterranean climate outdoors during the summer months and protected from cold temperatures during winter.

In colder climates keep in a greenhouse throughout the year.


Irrigation

Generously in summer and decreasing in winter.


Fertilization

From spring to autumn.

Transplant

Every 2 years in spring-summer.

Substratum

100% Akadama or mixed with 20% of volcanic clay.


Pruning and nipping

Pruning

The pruning is realised in spring.

Nipping

Using tweezers, prune back to 2 leaves after 4 to 6 leaves have grown. Ficus will bleed milky latex profusely. When the latex dries, it forms its own natural seal and it is not necessary to use any other cut paste as a sealant.

Fencing

Can be carried out throughout the year.


Curiosities

Growth of air-roots is a characteristic of many ficus species. The air-roots act as a strong support and aid the branches to grow extensively over great areas. Ficus Retusa are capable of growing epiphytically on other trees. With the help of birds or other animals that have eaten their fruits (figs), the seeds are laid on a tree top, making it the host tree. Roots start descending through the trunk of the host tree until they reach the ground and start strangling the host tree trunk.
