Cussonia

Family. Araliaceae.

Origin. South Africa.

Description. Cussonia is an evergreen, small, branched tree that grows up to 4 m in height in its natural environment. The root system is very strong, with thick and powerful roots. The trunk is thin, covered with light brown bark, often has a thickening at the base - caudex, which stores moisture. This species is especially attractive due to its spectacular green or gray-green leaves - large and deeply dissected into 7 - 9 segments, on long petioles. In spring, small greenish-yellow flowers may appear on the tops of the stems.

Height. Young trees grow quickly and can add 70 cm per year, adult specimens grow much more slowly. In culture, the height usually does not exceed 100 - 150 cm. With proper pruning, you can form a small bonsai.

Temperature conditions

Keep at a temperature of about 20° C during the growing season; in winter, provide a cool rest period - from 5 to 10° C.

Lighting

Cussonia loves brightly lit places without direct sunlight during the daytime. With a lack of light, the plant stretches out and becomes lanky and looks sickly.

Substrate

Nutritious soil with a high content of organic matter in the form of peat and leaf humus. River sand is added to improve drainage.

Feeding

During the growth period, feed 2 times a month. In autumn, stop feeding and let the tree rest.

Purpose

This species is often used in bonsai culture, and is planted in such a way that its powerful root system is visible.

Flowering time

Rarely blooms in cultivation.

Air humidity

Tolerates dry air from heated rooms, but it is better to spray the leaves periodically.

Soil moisture

Mature specimens become drought-resistant, while young seedlings require regular watering, especially in spring and summer. In winter, the soil should not dry out completely.

Transplant

Young cussonias are replanted annually in spring, adults need replanting on average every 2-3 years. When grown in the bonsai style, the root system is trimmed during replanting.

Reproduction

The best method of propagation is considered to be seed. Only fresh seeds are used for sowing, as long-term storage affects germination. The germination period takes 1 - 1.5 months. Seeds are sown in deep containers in spring and summer, as this allows for the formation of thick roots. Cussonia can be propagated by cuttings, but specimens obtained in this way may not develop attractive roots and caudex.

Pests and diseases

Rotting due to waterlogging.

Among the harmful insects, spider mites sometimes appear.
