Things to note about Star Begonia

Seasonal watering precautions

When the room temperature is below 15℃ in winter, watering should be strictly controlled, or spraying should be used instead of watering. The suitable temperature for growth is 18-21℃. Too high temperature can easily cause leaf scorch.

During hot seasons, pay attention to the surrounding air humidity and spray 2 to 3 times a day.

Overwintering

The wintering temperature should not be lower than 8℃. In winter, the plants should be placed in a shed where they can see sunlight in the morning and evening. Stop applying fertilizer and control watering. The leaves can be washed once a week with water close to room temperature.

How to propagate star begonia

Seed propagation

It can be done in early spring. Sow the mature seeds in a breeding pot filled with humus, maintain around 16℃ and a certain humidity, and they will take root. When the seedlings have 2 to 3 true leaves, they can be transplanted into pots.

Cutting propagation

The best effect is from May to June. Select the tender branches at the top of the plant as cuttings, about 10 to 15 cm long, and insert them into the culture sand bed. Spray the sand bed every day. Generally, roots will take shape 2 to 3 weeks after planting.

Propagation by division

Clumping varieties can also be propagated by division. Divide the roots of the plant that fills the pot into several clumps, avoiding damaging the roots, and then plant them in pots separately.

Disease and Pest Control of Star-spot Begonia

If root-knot worms harm the root system, it will affect the root absorption, causing the plant to be short and lose its green color. Nematicides such as kexiandan can be buried around the root system for prevention and control.

In addition, gray mold is prone to occur when the air humidity is too high and ventilation is poor, so ventilation should be strengthened and medication should be used.
