Winter care of round-leaf arrowroot

Round-leafed arrowroot is susceptible to low temperature damage

Low temperature damage can cause frostbite on the leaves, and in severe cases the entire plant can be frozen to death. In this case, it is difficult for the plant to survive. Another type of frost damage is caused when the night temperature in winter remains below 18°C, especially when the temperature drops to 10-15°C, which is not conducive to the survival of round-leaf arrowroot. It is very common indoors in the north in winter.

The damage caused by the latter to the arrowroot is not immediately apparent, but it is severe and acute in nature, with dark spots on the lower leaves and oily spots on the edges of the leaves.

Round-leaved arrowroot is susceptible to anthracnose

Due to poor ventilation, poor light transmittance, low temperature and high humidity in the greenhouse in winter, it is very easy to cause the plants to grow slowly and grow poorly, which will reduce the disease resistance of the round-leaf arrowroot plants and easily induce anthracnose and other diseases.

Winter care methods for round-leaf arrowroot

1. Strengthen the control of room temperature. The most suitable temperature is 18℃ at night, and it should reach 20-22℃ during the day.

2. Proper ventilation should be provided at noon to maintain optimal planting humidity.

3. Observe and maintain, pay attention to the occurrence of diseases, and do not water too much.

4. Cut off the diseased leaves in time and isolate the diseased and damaged plants.

5. Strengthen the management of fertilizer and water, water gently and slowly, not too fast, to prevent the spray from splashing onto the leaves.
