Pawpaw and banana trees.
What is bananas, over the past decade have learned all the inhabitants of Russia (many will gladly use them every day, especially the children); Banana - a thermophilic guest from Africa.
But the so-called banana tree - Pawpaw (Asimina triloba), or tri-Annona can grow in regions with relatively cold winters - not only as kadochnoe plant indoors, but in the open field; it successfully grown in the Crimea and the Caucasus. Pawpaw is also called Mexican banana or banana Nebraska; she got these names for an elongated (like a banana) shape of the fruit. It's not just fruit and ornamental plants; pawpaw seeds and leaves are used in medicine.
The birthplace of the Mexican banana are the southern United States. Currently, pawpaw is also common in Spain, France and Italy; in Russia it is imported in the last century. The fact that this plant is very hardy and can tolerate even severe winter frosts (up to -29 Â°). Flower buds of pawpaw, which appear in the beginning of April, thanks to a thin insulating shell completely free tolerate spring frosts.
Pawpaw - a deciduous tree reaching in favorable conditions, a few meters (at home about 12 meters); easily formed in a dwarf form. This is a very decorative plant with a broad pyramidal crown and a beautiful smooth bark; leaves are quite large (up to 30 cm long and 10 cm wide). Large drooping leaves pawpaw damaged in strong winds, it is necessary to take into account if it is grown it on the balcony or in the garden.
Pawpaw flowers red-purple, monoecious, large (up to 4 cm in diameter); calyx consists of three leaves, corolla - of six petals. Blossoms in the spring to deploy pawpaw leaves; bloom for a long period (about three weeks). This cross-pollinated plant; indoors need artificial pollination with a soft brush or cotton wool.
The fruits of pawpaw reach 12 cm in length and 5 cm in diameter, they are collected in the stems of eight or more fruits. Under the thin skin of the fruit is rich in fructose and sucrose flesh with a sweet flavor and a delicate pineapple-strawberry flavor. In fruit Pawpaw also contains all essential trace element, which are available in a tropical banana and persimmon. Pawpaw fruit pulp whitish-yellow, the consistency of butter.
When correct agricultural productivity of this crop is high (25 kg per tree and up). Thanks to a beautiful large leaves and flowers pawpaw very decorative. In the container, this plant grows well below its natural height. In the middle of the autumn leaves turn yellow and fall off pawpaw, and new leaves grow in late spring after flowering. Single flowers are the leaf axils of the previous years, in March-May.
Each flower pawpaw contains several pistils, which explains the ability of a single flower form about 9 fruits. Flowers bisexual, but not self-pollinating, so fruiting should be carried out cross-pollination (you need to have two trees). Pawpaw pollination carried out when it becomes brownish pollen and loose, and the tips of the pistils - glossy green and sticky. Pawpaw fruits ripen for 4 weeks; they contain 10-14 large brownish black seeds arranged in two rows.
Pawpaw light-requiring, but in the first two years of life requires a light shading from direct sun. Adult plants prefer full sunlight. Pawpaw seedlings develop slowly, but with an increase in the light of the day (16 hours), the growth rate increases: three months in a young tree can grow up to 1.5 meters in height. Pawpaw need watering from spring to fall regularly, constantly keeping the soil moist; but stagnant water should be avoided.
In Pawpaw fleshy brittle roots, so it is not transplanted, and rolled over. Do this in the spring when the plant start to grow. For good growth requires a deep pot as pawpaw develops a large root system.
Ground for pawpaw should be light, fertile and slightly acidic (pH 5-7), I recommend the following mixture: 2 parts rotted manure; 1 part humus sheet (from the oak or under birch); 1 piece of sod land; 0.25 parts fly ash; some sand.
During active growth Pawpaw fed by the following scheme (for example, take in June, but it should be done every month): 1 and June 15 - manure; June 8 - water-soluble fertilizer "Kemira -lyuks"; June 20 - ash from straw or potato tops (1 tsp ashes scattered on the soil surface and pour); June 25 - yl pond (150-200 g per liter of water).
In winter, a period of pawpaw deep rest, during which the plant requires a minimum of two weeks of cold and 160 days of cool content. Flowers and fruits in the pawpaw formed on old wood, so mature plants are cut annually for replacement. Before you start growing produce sanitary pruning.
Propagated pawpaw seeds and grafting. Pawpaw seeds for good germination must pass stratification at 0 Â° -4 Â° C for 90-120 days. Seeds germinate in 7 weeks; when planting in late fall to the ground, you can expect germination in July next year. Young sprouts pawpaw have sensitive root system, so they are not recommended to transplant.
Plants grown from seeds usually begin to bloom and bear fruit after 4-8 years, depending on the quality of seeds, varieties and conditions. Grafted tree may begin to bloom in 2-3 years, but it is very difficult to vaccinate pawpaw. The plant is resistant to pests.
