Osmanthus bonsai is a common type of potted plant, loved by people for its rich fragrance and beautiful flowers. In winter, due to the drop in temperature and humidity, the growing environment for osmanthus bonsai changes, requiring special care methods to maintain its healthy growth.

Control Indoor Temperature
To ensure normal growth of osmanthus bonsai in winter, the indoor temperature should be kept above 10°C. If the temperature is too low, it can cause the plant to grow slowly or stop growing, and may even lead to death.
Increase Light Exposure
Winter days are shorter, so indoor light exposure needs to be increased to ensure the plant can photosynthesize normally. You can use artificial light sources or place the plant in areas like balconies or windows that receive more sunlight.

Water Appropriately
Due to lower humidity in winter, osmanthus bonsai is susceptible to dryness, but it should not be overwatered. Watering frequency should be increased appropriately while keeping the soil from becoming overly moist to prevent issues like root rot.
Maintain Ventilation
The indoor air is dry in winter, so windows should be opened frequently for ventilation to keep the air circulating. However, avoid strong winds that could affect the plant's growth.
Mist the Leaves
The leaves of osmanthus bonsai need to stay moist, so you can mist them appropriately. However, avoid misting at night to prevent the leaves from frost damage.

Fertilizing
Winter is the dormant period for osmanthus bonsai, so no fertilization is needed. Over-fertilizing can lead to pests and diseases.
Prune Timely
Winter is the pruning season for osmanthus bonsai. Timely pruning can promote normal growth and prevent branches from crossing, which affects the tree's aesthetic shape.
Pest and Disease Control
Low humidity in winter can lead to pests and diseases like aphids and powdery mildew. Organic or chemical pesticides can be used for control, but pay attention to the dosage and choice of product.
Repot Appropriately
Winter is a suitable time to repot osmanthus bonsai, but choose the right time and method to keep the roots healthy. Also, pay attention to post-repotting care to avoid harming the plant.
Control Air Humidity
The indoor air humidity is low in winter. You can use a humidifier or place plants with higher humidity requirements around it, such as ivy.
Insulate the Roots
The indoor floor temperature is lower in winter. You can add some insulating materials under the osmanthus bonsai pot, such as peat soil or dry straw, to protect the roots.
Prevent Frost Damage
As the temperature drops in winter, it's important to prevent the plant from frost damage. You can spread a layer of straw or other insulating materials around the plant.
Clean Up Fallen Leaves Promptly
Osmanthus bonsai will shed some leaves in winter. Cleaning them up promptly can prevent the spread of bacteria around the plant.
Choose Suitable Varieties
Different varieties of osmanthus bonsai have varying abilities to adapt to winter. Choosing a suitable variety can reduce the difficulty of winter care.
Scientific Care
The winter care for osmanthus bonsai needs to be scientific and reasonable. Adjustments should be made according to the plant's growth needs and environmental changes to ensure it grows healthy and strong.
Osmanthus bonsai is a common type of potted plant. In winter, its care requires attention to factors like temperature, light, watering, and ventilation to prevent the plant from being affected by environmental changes. Only with scientific and reasonable care methods can osmanthus bonsai thrive in winter.
