Nyssa

The genus Nyssa contains about 10 species of hardy deciduous trees. Regular ovate and pointed leaves with a whole edge in autumn acquire a very bright color. The bark is light brown with deep cracks. The most common of them is Nyssa sylvatica. The young plant initially has a columnar shape, but over time it becomes more sprawling. Growth is rather slow, with numerous horizontal branches extending from the trunk, starting deep under the bark. In autumn, the green leaves turn scarlet or slightly orange. It's dioecious plant (male and female flowers are formed on different specimens). In June, nondescript greenish-yellow flowers bloom. Ovate blue-black drupe-shaped fruits with calyx remnants appear only on female plants. In the form of "Hanging" branches drooping, directed down. Other types are much less common. Water nyssa (N. aquatica) - a tree with oval-oblong leaves, covered with pubescence on the underside; young shoots are also pubescent. In nature, it grows in swampy forests. Nyssa chinensis (N. sinensis) grows both as a shrub and as a tree. Young shoots are red in color. Narrow egg-shaped leaves also acquire different shades of the red spectrum in autumn.

Cultivation

Water nyssa and forest nyssa are grown in the open ground in single plantings in parks and gardens as ornamental crops. They do not tolerate environmental pollution well, and it is not recommended to plant them in the city. These plants clearly prefer well-moistened soils, do not tolerate calcareous, alkaline ones. When planting, it is recommended to apply organic fertilizers at the rate of 4-5 kg per plant. In the period from May to August (only in the initial stage of development), once every 20-30 days, a complex mineral fertilizer is diluted in water for irrigation, top dressing is carried out. Pruning is reduced to removing dry and damaged branches.

Location

Plants of the genus Nyssa are suitable for both open sunny and semi-shaded (but in this case there will be a less intense autumn color of the foliage) place.

Temperature

These plants are resistant to fluctuations in air temperature.

Watering

It is required in times of drought, especially for young plants.

Reproduction

Most often, they resort to sowing seeds in October. Use seed soil (2/3 peat and 1/3 fertile land), keep in a closed, unheated room. When the seedlings grow up in late spring, they should be planted singly in pots filled with similar soil, to which a complex fertilizer is added at the rate of 30 g per bucket. Planted in a permanent place after 4-5 years. Propagate also layers. In October, long branches are buried near the base of the plant, after making incisions on them from the underside. After the formation of roots (this process can take 2-3 years), new plants are separated from the mother plant and immediately planted in the ground. Nyssa is well propagated by rhizomatous offspring.

Diseases

Most of the problems are related to inappropriate cultivation conditions, such as too dry land or air pollution. The first leads to a slowdown in plant growth, the second, since plants of the genus Nyssa are sensitive to sulfur dioxide and other air pollutants, manifests itself in the form of spots and discolored foliage, followed by its fall. These problems are solved only by preventive measures.

Acquisition

Nyssa can be found in specialized nurseries and horticultural centers offering the widest range of crops. Choose small specimens grown in containers or with a lump of earth, they are easier to tolerate the shock of transplanting.
