Decorative flowering tuberous begonias
All indoor begonias (Begonia) came to us from the tropics and subtropics of Asia, Africa and America. They can be divided into three groups: decorative-deciduous, bush and tuberous begonias. Tuberous begonias (Begonia tuberhybrida) breed with the help of tubers, as evidenced by their name. On sale you can find many varieties of this group of begonias. Their flowers are unusually bright and spectacular, in shape they resemble a rose.
Tuberous begonia flowers are non-double, semi-double and double; all kinds of shades of white, pink, orange, yellow and red. Tuberous begonias reach a height of 35-50 cm, their stalk is fleshy, the leaves are asymmetrical. Another type of tuberous begonia is the tuberous begonia (Begonia tuberhybrida pendula). This is an ampel plant that looks charming in a hanging planter or basket. The tuber begonia also includes the multi-flowered begonia (Begonia multiflora), which is characterized by a large number of small flowers.
Tuberous begonias are photophilous and tolerate only slight shading. In winter, they need a cool, at about 13 degrees, maintenance; in summer, the optimum temperature is about 20 degrees. Begonias require high humidity, it is better to place them on a pallet with wet pebbles or in a double pot with peat. When spraying should avoid getting water on the leaves, try to moisten the air around the plant.
In the store you can buy both an already flowering plant and tubers. It is better to buy tubers in the spring. Before planting, they must be soaked in a fungicide (for example, in “Vitaros”) and dried thoroughly to prevent the development of rot. After this, the tubers are planted in boxes with wet peat, which contain at a temperature of 15-20 degrees, when the sprouts become 5 cm long, the plants must be transplanted into separate pots.
As the soil, you can use the ready-made Begonia substrate, or a mixture of turf and leafy soil, humus, peat and sand in a ratio of 2: 1: 1: 1: 1. For prolonged and abundant flowering, tuberous begonias must be fed with complex fertilizer for flowering plants. Watering begonias during flowering should be plentiful, but the soil should not be waterlogged. After flowering is completed, watering is stopped, shoots are cut, tubers are taken from the ground, pickled, dried and stored in peat at a temperature of about 13 degrees.
Tuberous begonias are susceptible to fungal diseases. It is necessary to remove all diseased leaves and treat begonia with a non-specific fungicide. Brown spots on the leaves, on the surface of which a gray coating appears, are formed as a result of infection with gray rot. It is necessary to separate the diseased plant from the rest, remove the affected leaves and ventilate the room containing begonia well. A fungicide spray is also required.
Of the pests, begonias are affected by aphids and red spider mites. A number of problems arise with care errors. Dry leaf tips indicate low humidity; thin and poorly leafy stems - about a lack of light; dry and twisted leaves - about too high air temperature; yellow, withering and decaying leaves - about an excess of moisture in the soil. Falling buds can be caused by dry air or waterlogging of the earth. If the plant dies, inspect its tubers. They can be affected by nematodes, in this case there will be swellings on the roots, or a weevil, then you will find the passages eaten in the tuber. Rotten roots indicate excess watering.
All the problems in care are fully compensated by the spectacular appearance of flowering begonias, which will decorate any room and uplift their brightness and expressiveness.
