A family of grapes. Homeland tropical sometimes subtropical regions of America, Australia, Asia. About 350 species are widespread in nature. These are evergreen vines that can be grown as an ampelous plant or tied to a support. Cissus looks spectacular if, twisting around a tube with moss, it grows up. Cissus are rather fast growing.
Cissus rhomboid Cissus rhombifolia is a herbaceous vine. The leaves are alternately arranged, ternary, diamond-shaped, with a rarely toothed edge, dark green in color. It forms antennae, which themselves seek support and curl around it. Stems and petioles densely pubescent with fine hairs. In nature, it blooms with small greenish flowers, collected in racemose inflorescences. After flowering, forms red edible berries. Does not bloom in indoor conditions. This species is the most unpretentious to grow. Often in culture you can find a variety of cissus rhomboid - variety 'Helen Danika'.
Antarctic Cissus Cissus antarctica is a herbaceous vine. The leaves are alternately arranged, ovoid, up to 10 cm long, with a sparsely toothed edge, dark green. Stems and petioles, and antennae densely pubescent with brown hairs. The flowers are greenish, collected in corymbose inflorescences.
Cissus discolor Cissus discolor is a rather demanding plant. The leaves are alternately arranged, ovoid (almost arrow-shaped), with a heart-shaped base and a finely toothed margin. The leaf surface is velvety green or olive, with silvery spots between the veins. The underside of the leaf, petioles and stems are purple.
Temperature: Normal in summer, room temperature, in winter it is cooler about 15-18 ° C, at least in winter 10-12 ° C (multicolored cissus is more thermophilic, for it the winter minimum is 16 ° C). Cissus is an unpretentious plant, but still does not like two extremes - drafts in the cold season, and heat in summer - the leaves dry and fall off.
Lighting: Bright diffused light, light partial shade. To get a lush, beautiful bush, you need direct sun in the morning or evening. This is the sill of the east window or northwest window. In a room with a south or west window, the cissus should be placed in the immediate vicinity of the windowsill, but under shade. Cissus Antarctic is more shade-tolerant, grows well on northern windows.
Watering: Abundant from spring to autumn. In winter (from October to February), watering is moderate. Cissus does not tolerate complete overdrying of an earthen coma (the leaves at the base of the stems dry and fall off), but excess water, long drying of the soil, can lead to decay of the roots and death of the plant.
Fertilizing: Cissus is a fast growing plant, it intensively consumes nutrients from the soil, therefore it is fed every two weeks from April to September using liquid fertilizer for decorative foliage plants.
Air humidity: Cissus responds well to regular spraying, and if it is in a room with central heating, then frequent spraying - morning and evening - becomes a necessity. With the end of the dormant period - in the spring, after transplanting, it would be nice to give the cissus a warm shower in order to wash off the accumulated dust and encourage the plant. Cissus multicolored does not tolerate dry air, the leaves become like parchment, it is better to place it on a tray with wet sphagnum moss.
Transfer: Soil - 1 part of sod, 1 part of leaf (or peat) land, 1 part of humus, 1 part of sand. Young plants are transplanted annually, and plants older than 5-6 years after a year, but feeding is carried out every year. For greater bushiness, you can pinch the apical shoot bud from the cissus.
Reproduction: Cuttings in spring and summer, to do this, cut off several apical cuttings, and after rooting, they are planted in one pot. It is better to root cuttings in spring or summer, but it is possible at other times of the year, if it is light, cissus cuttings root easily in water.
Yellowing of leaves - may be due to lack of watering, if the soil is too depleted, or saline soil from watering with very hard water. Also, the leaves turn yellow when kept in a warm room with dry air during the heating season.
The leaves become pale - if the light is too bright, burns form on the leaves in direct sunlight. It should be noted that in poor lighting conditions, cissus plants are strongly exposed in the lower part of the stems, the plant slows down its growth and loses its decorative attractiveness. Moreover, it was noticed that the variety of cissus rhomboid "Helen Danica" is more light-loving than the usual rhomboid cissus.
Brown leaf tips are most likely due to dry air, possibly due to insufficient watering, exposure to cold air, or touching cold glass in winter.
Brown spots on the leaves (not on the tips, but on the sides) - with waterlogging of the soil or a sharp drop in temperature. If at the same time the tops of the shoots begin to droop, the plant must be urgently removed from the pot and transplanted into dry soil.
