Nicotiana

The genus Tobacco (Nicotiana) contains 70 species of herbaceous annuals and perennials, from resistant to tender, grown as annuals. Winged tobacco (Nicotiana alata) - a species up to 1.5 m tall with oblong leaves and fragrant flowers, white on the outside and greenish-yellow inside, blooming on summer nights. Many hybrids with flowers of yellow, pink, crimson, but not white color is obtained from it. Winged multi-flowered tobacco is widely grown (n. alata var. grandiflora) is a perennial used as an annexe. Forget Tobacco (n. forgetiana) - a species with oblong pubescent leaves and purple-red bell-shaped flowers collected in panicles. Erect branching shrub 80-150 cm tall. The leaves are large, elongated, covered, like the stems, with glandular hairs. The flowers are fragrant cleavage-petals (5 petals fused at the base into a long tube), collected at the end of the shoot in a paniculate inflorescence. The flowers are closed for the day. Glaucous tobacco (N. glauca) is a root-springing species with a height of 80-100 cm, with lower elongated-spatulate leaves; the leaves located higher on the stem are ovate-lanceolate. The flowers are drooping greenish-purple, white inside, bloom in late summer and early autumn, open only at night. Sander's tobacco (n. x sanderae) is a garden hybrid of winged tobacco and Forget tobacco, from which many cultivars of various colors and heights (from 40 to 80 cm) are obtained. The Nikki and Formanan hybrid groups have red flowers. Sander's tobacco is a shrub 60-100 cm high; the flowers are red, white and other colors, odorless, do not close for a day. Real tobacco (n. tabacum) is a species over 100 cm tall with pink, red and dark red flowers. This is the most common type, because smoking tobacco is obtained from its leaves. Among the newly developed tobacco varieties, the most famous is the Havana group. The plants included in it are compact, with many flowers that can be painted in various colors. They are particularly well suited for planting in flower beds.

Cultivation

Decorative tobacco is grown in the open ground in flower beds, in borders or pots on balconies and terraces. Plants are planted permanently in spring, preferably in loamy, organic-rich soil. Basic application of full mineral fertilizer (30 g / m2) - when landing. Plants are planted at a distance of 30-80 cm from each other, depending on their development. Potted soil should consist of 50% garden land, 25% peat and 25% sand. When growing in pots in spring and summer, once every 20 days, a complex mineral fertilizer is added to the water for irrigation in the amount of 10-20 g per bucket.

Location

All species and hybrids require a sunny place, you can shade. But in summer, potted specimens are sheltered from direct sunlight.

Temperature

These plants are thermophilic, resistant to high air temperatures.

Watering

When growing tobacco in the open ground, keep the soil moist at all times. Potted plants should be watered regularly and abundantly.

Reproduction

Propagate by sowing seeds in the ground or in greenhouses. Seeds are not embedded in the soil, do not cover with earth. Seedlings are unpicked in pots, containers or flower beds.

Diseases

Plants are afraid of aphids, which cause yellowing of leaves, weakening of plants, and are also carriers of viral diseases (as a result-dwarfism, deformation of stems and leaves, change in leaf color). They get rid of them with the help of drugs against these insects.
