In winter, the cold climate puts many plants into a dormant state, and bonsai are no exception. Not all bonsai are cold-resistant; some are easily damaged by frost in the cold winter. Which bonsai fear the cold? This article will introduce you in detail.
Which bonsai fear the cold?1. foliage bonsai
Foliage bonsai such as five-needle pines, podocarpus macrophyllus, and black pines are sensitive to temperature and not cold-resistant. In winter, when the temperature drops below 5°C, these bonsai may show symptoms such as yellowing and shedding of leaves.
2. fruit-viewing bonsai
Fruit-viewing bonsai such as golden berry, pomegranate, and wolfberry have higher temperature requirements in winter. When the temperature drops below 0°C, the fruits of these bonsai are easily damaged by frost, affecting their ornamental value.
3. Aquatic bonsai
Aquatic bonsai such as lotus and water lilies have higher temperature requirements and are not cold-resistant. In winter, when the temperature drops below 5°C, the roots of these bonsai are easily damaged by frost, leading to plant death.
4. succulents
Succulents such as Crassulaceae and cacti are sensitive to temperature and not cold-resistant. When the temperature drops below 0°C, these bonsai may show symptoms such as leaf frostbite and rot.
Winter care guide for cold-sensitive bonsai1. Reasonable placement
Place cold-sensitive bonsai in warm indoor areas, avoiding direct exposure to cold winds. If possible, place the bonsai near a heater to maintain a room temperature above 5°C.
2. Proper shading
In winter, the sunlight is weaker, but the UV radiation is strong, which can easily damage the bonsai. Proper shading should be provided to avoid strong sunlight exposure.
3. Control watering
In winter, the temperature is low, and the evaporation of the bonsai is reduced, so the watering frequency should be reduced accordingly. Keep the soil slightly moist and avoid excessive watering that can lead to root rot.
4. Strengthen insulation
For cold-sensitive bonsai, the following insulation measures can be taken:
(1) Cover the bonsai with materials such as plastic film and cotton blankets to provide insulation;
(2) Place the bonsai indoors, using the warm indoor environment to protect the bonsai;
(3) Place a heater around the bonsai to increase the surrounding temperature.
Which bonsai fear the cold? This article introduces several cold-sensitive bonsai such as foliage, fruit-viewing, aquatic, and succulents. In winter, we should pay attention to the proper care of these bonsai to ensure they survive the winter safely. I hope this article is helpful to you.
