The Fig Bonsai: The Taste of the Mediterranean

The Common Fig(Ficus carica) is a highly satisfying bonsai tree, capable of immediately evoking sunny landscapes and dry stone walls. Unlike tropical Ficus (such as Retusa or Ginseng), the Native Fig is a deciduous plant: it loses its leaves in winter, displaying a beautiful smooth, light-gray bark and branching that can become very striking. The main challenge with this essence is to reduce the size of the leaves, which are naturally large, but with the right technique you can achieve proportionate results and, most importantly, miniature edible fruits.

Origin & species

Native to Caria (a region in Asia Minor, hence the name carica) and widespread throughout the Mediterranean for thousands of years. It belongs to the Moraceae family. It is a robust tree, almost pest-like in nature because of its ability to root anywhere. In bonsai, small-fruited varieties or those with more lobed leaves are appreciated, but the common wild fig is also good to start with.

Exposure and Microclimate

The Fig tree demands full sun.
Direct sun exposure is the only real "secret" to shrinking leaves and shortening internodes. If kept in shade, the leaves will become huge and the branches long and weak.
It loves heat and ventilation. In summer, it can withstand scorching temperatures without any problems, as long as the roots do not "boil" inside too small a pot.

Watering

Having large leaves that transpire a lot, the Fig drinks a lot in summer.
Water generously as soon as the potting soil dries to the surface.
However, be careful: if you want to reduce leaf size, you should not spoil it too much with water in spring during bud opening. Light water control helps to keep them compact. Absolutely avoid stagnation: fleshy roots rot quickly.

Water quality

This is an extremely tolerant plant.
It accepts tap water, even calcareous water. It does not need special water, being used to growing on poor, rocky soils.

Substrate

Requires a draining but nutritious substrate.

• Recommended mix: 50 percent Pumice (or Akadama), 30 percent Lapillus and 20 percent Universal Potting Soil or Humus.
• The organic component is important because the Fig is a voracious plant that consumes a lot of energy to produce fruit and leaves.

Repotting

This is done in spring (April), when the buds begin to swell.
It is repotted every 2 years the young, every 3-4 years the old.
The root system is very powerful and invades the pot quickly. You can be drastic in pruning the large, woody roots; the Fig issues new roots very easily.

Fertilization

Fertilize generously from spring to fall.
In spring use a balanced organic fertilizer.
From June onward, if you want to encourage figs to ripen, use a fertilizer with a high Potassium (K) content. Avoid excess Nitrogen if the leaves are already too large.

Flowering and fruiting

The Fig has no visible "flower" in the classical sense: what we eat (the syconium) is actually a closed inflorescence.
Fruits appear in summer and ripen in late summer/autumn.
On bonsai, let only a few fruits (2-3) ripen to enjoy the purple or green color, otherwise the plant will stop growing to feed the figs.

Structure pruning

This is done in late winter.
Fig wood is tender and has a hollow or spongy pith.
Basic rule: When you cut a large branch, immediately cover it with mastic. If you leave the pith exposed, the branch will rot by hollowing out inside to the main trunk. Cuts heal slowly.

Maintenance pruning (Defoliation)

During the season, shorten branches to 2 nodes when they have made 5-6 leaves.
The queen technique for the Fig tree is defoliation in June. By cutting away all the leaves (leaving the petiole), you force the tree to produce new ones in midsummer-these will be much smaller and more numerous. Do this only on healthy plants.

Pinching

In spring, pinch off the apical bud after the first 2-3 leaves have formed to stop branch elongation.

Tying & bending

Branches are flexible when young, but watch out for the bark: it is smooth and delicate, and will mark right away.
Also, every time you bend or cut, white stinging latex will come out.
Apply the wire in summer, but check it every 15 days because branch swelling is so fast.

Diseases and pests

• Mealybug: Often sticks under leaves or on branches (scale).
• Red spider mite: In summer if it is hot and dry.
• Fig fly: Can affect fruit by dropping them.

Winter & protections

In the Central and South it lives outside year-round.
In the North it is hardy, but potted roots fear prolonged frost (the pot becomes a block of ice). Protect the pot with mulch or put it in a cold greenhouse if temperatures drop below -5°C for days.

Annual calendar

• January-February: Structural pruning, cut protection.
• March-April: Repotting, start fertilizing.
• May: Pruning, pest control.
• June: Defoliation (to shrink leaves), wire.
• July-August: Abundant watering, fruit ripening.
• September-October: Fall fertilization (PK), remove wire.
• November-December: Leaf fall, rest.

Useful products for this bonsai

• Hanagokoro Organic Fertilizer (Basic nutrition)
• Healing Mastic (Mandatory for hollow pith)
• Oblique pith cutter (For clean cuts)
• Coppered aluminum wire (For setting)
• Earthworm humus (To support fruiting)

Frequently Asked Questions about the Fig Tree

Is white latex poisonous?
It is irritating and phototoxic. If it gets on your skin and then you expose yourself to the sun, it can cause burning or staining. Wash your hands well after touching the latex and be careful of your eyes.

How do I get small leaves?
Three rules: 1) Full sun. 2) Small pot (constricts roots). 3) Total defoliation in June. If you grow the fig in a large pot and in the shade, the leaves will always remain huge.

Why do figs fall before they ripen?
Often it is water shortage. The syconium (the fruit) is full of water; if the plant is thirsty, it "drinks" water from the fruit causing it to shrivel and fall. Water more when the fruit is there.
