I. Introduction to Cissus sicyoides:

1. What does Cissus sicyoides look like?

The vines of Cissus sicyoides grow about 10 to 15 m long and are climbing stems. It has simple leaves arranged alternately. The leaves are dark green and broadly ovate, with slightly pointed tips and serrated margins. Each node produces aerial roots, and the short aerial roots bear many lateral roots, growing vertically downward. The newly grown roots are purplish red and feel smooth and tender. When they mature, the roots turn yellow-green and feel tough and strong. The flowers are white-green, and the fruits are round with needle-like protrusions at the top.

2. Where does Cissus sicyoides originate?

II. What are the potted planting methods for Cissus sicyoides?

1. Light requirements: Can it be exposed to full sun?

Cissus sicyoides is native to the tropics and is a light-loving plant, but it is not tolerant of strong sunlight exposure, so it should be given enough light in spring, autumn, and winter, and appropriately shaded in summer.

2. Temperature requirements: What temperature is best for growth?

Cissus sicyoides grows best at 22 to 30 degrees, and in winter it grows best when the temperature is above 10 degrees, so in winter it should be moved indoors in time and the room temperature should be kept above 10 degrees to avoid stagnation of growth.

3. Pruning and shaping: When is the best time to prune?

When the winter cold wave is about to arrive, diseased branches, weak branches, withered branches, and other branches unfavorable to the plant's growth should be cut off to help it overwinter safely.

4. Fertilizer requirements: What are the fertilizer requirements?

Potted Cissus sicyoides does not have high fertilizer requirements, but poor nutrition can occur depending on the size of the pot, so a base fertilizer should be applied every one or two months to ensure sufficient nutrients.

III. What should be done if black spots appear on Cissus sicyoides leaves?

Cause 1: Lack of ventilation. Cissus sicyoides grows quickly and will produce various branches, so in addition to pruning, it also needs timely ventilation to improve a humid and stuffy indoor environment. If it is not ventilated for a long time, black spots will appear on the leaves and affect its ornamental value.

Solution: Place it in a place with good ventilation, such as a balcony, especially in winter. If you are worried that the plant will be harmed by the cold, you can open a small ventilation opening appropriately.

Cause 2: No pruning. Cissus sicyoides grows quickly and will produce diseased branches, weak branches, dead branches, and other branches unfavorable to the plant's growth, so these branches should be cut off according to the actual situation. If they are not cut, black spots will form on the leaves.

Solution: Regularly cut off all diseased branches, dead branches, weak branches, and so on, then place the plant in a ventilated place for a period of cultivation, and the leaves will recover.

Cause 3: Too much watering. Cissus sicyoides has relatively high water requirements, but that does not mean the more the better. If watered too much, the potting soil will become too wet and breed various diseases, causing the leaves to turn black.

Solution: Move the plant to a ventilated place and let some of the water evaporate appropriately. At the same time, when watering later, if the soil is not dry, there is no need to water.

The above is a detailed introduction to the potted planting methods for Cissus sicyoides and the solutions to the problem of blackening leaves. I hope it is helpful to everyone.
