"Gajumaru," with its plump trunk and unique aerial roots, is a captivating plant.
In Okinawa, it is said to be home to a spirit called "Kijimuna," and is cherished as the "Tree of Happiness."
Gajumaru is extremely vigorous and perfect for those new to houseplants.

Here, we will thoroughly explain the basics and tips for growing Gajumaru healthily and for a long time, while maintaining its distinctive form.

1. What kind of plant is Gajumaru?

Gajumaru is a plant of the mulberry family distributed in tropical and subtropical regions.
Its most striking feature is its "aerial roots" that grow from the middle of the trunk like octopus legs.
These roots burrow into the soil and possess enough vitality to break through asphalt.

2. Three basics for growing Gajumaru

The most important things for growing Gajumaru are "sunlight" and "balanced watering."

① Location (Sunlight)

Gajumaru loves sunlight.

• Best location: A windowsill where soft light comes through sheer curtains.

• Spring/Autumn: It grows well outdoors in sunny spots, but be careful as direct sunlight in midsummer can cause "leaf burn."

• Shade tolerance: It won't die in the shade, but lack of sunlight can cause "etiolation," where branches grow spindly and the trunk becomes thin.
  Place it in as bright a spot as possible.

② Temperature management

Being tropical, it dislikes cold.

• Wintering: Bring it indoors when the temperature drops below 10℃.

• Caution: Windowsills get cold at night, so it's safer to move it to the center of the room or a higher spot (e.g., on a shelf).
  Also, avoid places where air conditioner drafts hit it directly, as this can cause dryness and wilting.

③ Watering (Seasonal balance)

Water when the soil is dry. "Constantly moist" conditions can lead to root rot.

• Spring to Autumn (Growing season): When the soil surface turns whitish and dry, water thoroughly until water drains from the bottom of the pot.

• Winter (Dormancy): Growth slows down, so its ability to absorb water weakens.
  Water sparingly, 2 to 3 days after the soil surface has dried.

Point: Misting leaves. Misting the leaves with a spray bottle not only prevents dryness but is also very effective in preventing spider mites, a major enemy of Gajumaru.

3. Pruning to shape

Gajumaru grows rapidly, so if left unattended, its branches can become unruly and unbalanced.

Basic pruning (around May-September)

Cut back overgrown or crowded branches with pruning shears.

• Tip: Cutting just above a branch junction (node) encourages new shoots to emerge there.

• Beware of white sap: The white sap that comes out of the cut surface can cause a rash if touched, so wear gloves when working.

A bold move? "Bald" pruning

A unique Gajumaru technique is "bald" pruning, where all leaves are cut off, leaving only the branches.
This is done when the "shape has become disfigured" or if you "want to reset it and rebuild."
Because of its strong vitality, if done during the growing season (May-June), new shoots will sprout in about a month, resulting in a more compact tree shape.

4. When to repot

Gajumaru has vigorous root growth, so it needs to be repotted every 1-2 years.

【Repot if you see these signs!】

• Roots protruding from the bottom of the pot

• Water doesn't soak in when watering

• Leaves turn yellow and fall off (possible root bound)

Timing: Repot during the warm season from May to September. Use potting soil for houseplants and repot into a pot one size larger.

5. Common problems and solutions

Although Gajumaru is sturdy, it can show signs of stress due to environmental changes.

Leaves turn yellow and fall off

• Cause: "Lack of sunlight" or "sudden environmental changes (such as cold)" are possible.

• Solution: Don't move it suddenly; gradually shift it to a brighter location or a warmer spot and observe.

Trunk is soft and mushy

• Cause: Highly likely to be "root rot." Are you overwatering, or is water pooling in the saucer?

• Solution: Stop watering and let it dry out. In severe cases, you'll need to remove the rotten roots and repot it in fresh soil.

Pests (scale insects, spider mites)

• Solution: If you see small insects (spider mites) on the underside of the leaves, spray them off with a strong shower or apply pesticides. For white shell-like insects (scale insects), scrub them off with a toothbrush.

6. Gajumaru Feng Shui and Flower Language

Gajumaru is popular not only for its aesthetic appeal but also for its auspiciousness.

• Flower language: "Health," "Abundance of happiness"

• Feng Shui effects: Gajumaru, with its round leaves growing downwards, is believed to "calm energy" and have "relaxing effects."
  It is also famous as an item for improving financial luck.

• Recommended placement:

  • Bedroom: To calm negative energy and promote restful sleep.

  • Entrance/Living room: To enhance overall household luck and family harmony.

Summary: Live with Gajumaru

With its unique appearance, Gajumaru is charming just by being there.
As long as you follow the basics of "providing sunlight" and "watering when the soil dries," it will grow surprisingly vigorously.

Gajumaru allows for a healthy distance without constant attention, making it a kind plant for busy people.
