Ficus retusa, a giant turned dwarf
The Ficus retusa is often cultivated in our latitudes as a bonsai. But in its natural habitat, the rainforests of Indonesia and Java, this plant of the Moraceae family has an altogether different stature.
How to recognize Ficus retusa?
Ficus retusa can reach a height of ten meters and a spread of just as much. It is a shrub with a splayed habit. Partly epiphytic, it develops aerial roots which it uses to support itself on other trees.
Its light-gray trunk measures up to a meter in diameter. Its twigs are covered in white down and dotted with brown hairs.
Leaves grow spirally on the branches. Larger than those of Ficus microcarpa or Ficus pumila, they are up to 15 cm long and 6 cm wide. The leathery blades are oval or oblong and deep green in color.
Like other fig trees, Ficus retusa produces false fruits called sycones. These yellow to brown figs contain seeds and flowers.
The fruits are inedible and the rest of the plant is toxic, especially to cats. If your pet ingests the leaves, it may suffer from diarrhoea, vomiting and hypersalivation. Want to start growing bonsai, but your house looks like Noah's Ark? Better try an Olivier.
Our maintenance tips
Ficus retusa don't like change. Once yours has been installed away from draughts, don't move it again. It could lose its leaves.
Watering
Ficus retusa needs a regular supply of water. But, like many plants, the plant cannot tolerate excess. Check that the potting soil has dried on the surface (two to three centimetres) before watering. If this is the case, use non-calcareous water at room temperature. You only need to moisten the root ball, not the soil.
Don't forget to drain off any stagnant water in the saucer or planter. It could rot the roots.
Spray
Your Ficus retusa loves humidity. But the air in our homes is often too dry! To remedy this, spray the foliage with non-calcareous water.
In addition to increasing humidity, misting dusts the leaves and limits pest attacks.
Repotting
Every spring, repot your Ficus retusa to give it more space.
In a large, perforated pot, place a bed of clay balls, gravel or small pebbles about 20% of the way up. This layer promotes drainage and prevents root rot.
Fill your pot with a draining substrate, such as potting soil for green plants. Plant your Ficus retusa in the center and cover.
To improve humidity, place your plant in a saucer filled with moist clay balls.
Fertilization
To promote the growth of your Ficus retusa, apply fertilizer in spring and summer.
Apply a liquid fertilizer for green plants to stimulate growth.
Cleaning
To improve photosynthesis, clean the foliage with a damp sponge.
Prune
Trim your Ficus retusa, whatever its size, to make it denser. Use a clean, sharp tool. Shorten each branch by at least five centimetres, cutting above a healthy leaf. Remove dead branches too.
Caution! Sap is toxic. Wear gloves for protection.
Plantation
When the risk of frost has passed, it's time to plant.
Find a sheltered, sunny spot . It will be ideal for planting your Ficus retusa.
Soak the rootball to rehydrate it. Meanwhile, dig a hole two or three times as big. Remove any stones, weeds or other roots that might hinder the growth of your shrub.
To enrich the soil, you can place a layer of compost at the bottom of the hole. Then place your specimen in the center. The collar should be level with the ground. Fill in with a mixture of garden soil, potting soil and sand.
Water to eliminate air bubbles and encourage rooting.
Finish by mulching the base. This will limit weed growth and water evaporation.
Cutting
Cutting is carried out during the strong growth phase, generally in spring and early summer.
Cut off the end of a branch about fifteen centimeters long. Remove all leaves except the top pair.
Immerse your stem in a glass of water at room temperature. Place the cutting in a sunny, draught-free spot. Remember to change the water to keep it clear.
When the roots are at least three centimetres long, you can repot your young shoot.
