Blooming begonias are prized for the beauty and abundance of their flowers. Among them there are evergreens that can be kept at home throughout the year, for example, evergreen begonia.

Some of the most spectacular blooming begonias are tuberous begonias, which are potted crops such as, for example, the Lorrain begonia hybrids and the Elatior begonia hybrids. These plants, after flowering, finish their growing period and are usually thrown away. Tuberous begonias bloom in summer and autumn (with good care from spring to December), in winter they lose their leaves.

In the fall, when tuberous begonias begin to go into a dormant state, watering is reduced, and after the leaves fall off, they stop altogether. The tubers are freed from the ground and stored in boxes in the sand, in a cool room. During the wintering of tubers in a room, in pots, they are watered from time to time, but not allowing dampness.

At home, both species of begonias are grown: Begonia coccinea, Begonia glaucophylla, etc., and hybrids obtained by crossing two or more types of begonias, and many of them have very beautiful leaves and at the same time bloom beautifully and profusely.

Species flowering begonias

Bright red begonia Begonia coccinea is a large, little branching bushy plant with erect stems, on average, the height of the bush is 1.5 m, but it can be higher, while the shoots begin to droop from their own weight, require support. Part of old tub plants, the stems are bare at the bottom. The leaves are oblong-ovoid, with a wavy edge about 12 cm long on shortened petioles. The surface of the leaf is smooth and shiny, light green in color, without spots, the reverse side and edge of the leaf have a reddish tint. Bright red or pink flowers are collected in panicle inflorescences.

Gray-leaved begonia Begonia glaucophylla is a bushy, well-branching plant, reaches 1 m in height. Shoots are erect at first, then drooping. Over time, the plant takes on an ampelous shape and is grown in hanging pots. Leaves are ovoid, pointed at the end, with a slightly wavy edge, up to 12 cm long, on short petioles. The leaf surface is smooth, bright green in color, without spots. Red (coral and red-pink) flowers, about 1.5 cm in diameter, collected in a raceme inflorescence. Synonyms: Begonia limmingheana (limmingheiana), Begonia radicans, Begonia procumbens. It blooms willingly and easily if the soil is sufficiently nutritious, flowering is long, mainly in the summer months.

The ever-flowering begonia Begonia semperflorens is a small bushy plant, the shoots are about 60 cm long. In a young bush, they are erect, then droop, and an adult plant has a semi-ampel or ampel form. Leaves are rounded, slightly pubescent along the edge, up to 6 cm long. The leaf surface is light green, but it can be dark green and with a reddish tint. Flowers are collected in a loose panicle on a short peduncle. Flowers can be simple or double up to 2.5 cm in diameter, white, pink or red. Differs in long flowering, the inflorescences themselves are short-lived, they bloom faster in hot weather, but to replace the wilted ones, new buds immediately bloom. Flowering peaks in the summer and autumn months. May continue to bloom in winter, especially if there is enough light and nutrients.

Flowering begonias hybrids

These begonias are quite diverse, differ in the size and shape of the bush, the shape of the inflorescences, there are differences in care. Flowering begonias hybrids are combined into separate groups:

Coral begonia Begonia x 'Corallina de Lucerna' - mushroom begonia obtained from crossing Begonia teuscheri x Begonia coccinea.

Large bushy plant with erect stems. Leaves are oblong-ovoid, pointed at the end, with a serrated edge, up to 15 cm long. The surface of the leaf is green with white blotches or specks, the reverse side with a reddish tint. Bright pink flowers are collected in multi-flowered inflorescences raceme. This hybrid usually refers to decorative leafy begonias, but sometimes it blooms so profusely and for a long time that it would be more correct to attribute it to both groups, including decorative flowering ones.

Begonia Lorrain
Begonia Lorrain

Begonia Lorrain

The begonias of the Lorrain group Begonia x Lorrain (Begonia hybrida Gloire de Lorraine) are a group of hybrids.

Plants form small bushes up to 50 cm tall, with thin, slightly drooping stems. Leaves are rounded, wavy along the edge, up to 10 cm in diameter. The leaf surface is green or dark green. Flowers about 2.5 cm in diameter, on short peduncles in loose panicles, simple (not double), usually pink with various shades and white. The main flowering occurs in autumn - early winter. They often bloom for the New Year and Christmas.

Begonia Elatior

Begonias of the Elatior group Begonia x Elatior is a group of hybrids.

Plants form small bushes up to 35 cm tall. Leaves are rounded (pointed in some varieties), serrated along the edge, up to 10 cm in diameter on reddish thin stems. The leaf surface is green. The species is similar to the previous one, but the flowers are larger, about 5 cm in diameter, on short peduncles in loose panicles. The flower shape is often double or semi-double. In some flowers, the edges of the petals are even, in others - serrated, in others - slightly serrated. Any color is widespread: white, pink, coral, scarlet, peach, yellow, orange, etc. Flowering - at any time of the year.

Tuberous begonia

Tuberous begonia Begonia x tuberhybrida is a group of complex hybrids that includes several subgroups.

Differs in the presence of a fleshy underground tuber-rhizome. The height of the bush varies in some subgroups about 30 cm, in others 80-90 cm. Subgroups of tuberous begonias are classified by size and flower shape: small flowers, medium, large, simple flowers, semi-double and double. The shape of the leaves is also slightly different, but they are all on short petioles, asymmetrical, pointed at the end, as a rule, with a jagged edge. But this group of real blooming begonias, all the charm of this group is in abundant and beautiful flowering. The color of flowers can be any - white, pink, salmon, red, purple, orange, yellow, etc., except for purple and blue shades.

How to care for begonia

Care features: when growing begonias for their flowers, it is necessary to regularly cut out small female flowers that appear next to spectacular male flowers. Constantly picking old wilting flowers. Inspect the plants periodically to prevent pests and diseases and ventilate the area without creating cold drafts.

Temperature

Moderate temperatures above 26-28 ° C are undesirable for these begonias. Winter temperatures are around 17-18 ° C, but not lower than 15 ° C.

Lighting

Bright lighting, with obligatory protection from direct sunlight during hot times of the day (from 12:00 to 16:00). East, south-east, west, north-west windows are suitable. During flowering, begonias should stand on the windows not crowded, so that one flower does not obstruct the other. To maintain proper growth, they are periodically turned.

Watering

Abundant in spring and summer, but do not flood. begonias do not like stagnant water, as well as the complete drying out of an earthen coma. The water should be soft, settled. If water flows into the sump, it must be drained. All begonias are very sensitive to overflow, and contrary to stereotypes about tropical plants, it is easier to tolerate a delay in watering than too frequent waterlogging. Tuberous potted begonias are not watered in winter, they are stored in a dry peat substrate.

Air humidity

Begonias love high humidity, but do not tolerate spraying. Practice has shown that almost all types of begonias react to the ingress of moisture on the leaves with the appearance of brown spots. Therefore, in hot, dry weather, you can place begonias pots on a tray or box of wet peat or moss.

Transfer

In early spring, the tubers are planted in fresh soil. Rhizome begonias are transplanted as needed, when the pot is already cramped. Nutrient soil - a mixture of humus, leaf and sod land with the addition of a small amount of coniferous soil and river sand. In this case, the earth is not filled up to the top, so that later, when additional roots are formed, it would be possible to fill up the earth. It is absolutely necessary to pour drainage on the bottom of the pot, because begonia roots are very sensitive to stagnant water.

Fertilizer

It is useful to fertilize decorative flowering begonias from the moment of flower buds formation with liquid complex fertilizer for flowering indoor plants once every two weeks. Do not use nitrogenous fertilizers on ornamental foliage plants, as this will lead to leaf growth and suppression of flowering.

Reproduction

Propagated by stem cuttings and seeds. Tuberous begonias also multiply by dividing sprouted tubers. The tuber is cut in half, so that each part has sprouts and roots, the cuts on the tuber are sprinkled with charcoal or sulfur. The nodules are planted so that its top would rise slightly above the soil level.

Problems of growing begonias

The leaves turn yellow or discolored, the flowers lose their color - with insufficient watering or lack of nutrients in the soil. The same symptoms can be with a lack of light or too bright sunlight in shade-tolerant begonias.

Brown dry tips of the leaves - too dry indoor air, insufficient watering, lack of potassium in flowering begonias.

The leaves are pale, sluggish, on the petioles there are areas of softening - excessive watering, causing stem rot.

Falling leaves and flowers - cold drafts, watering with cold water, a strong lack of light, excess moisture in the soil, too high or too low room temperature.

Diseases of Begonias

Powdery mildew. Fungal disease - white or grayish bloom appears on leaves, flowers, buds, shoots, as if covered with dust. Gradually, the affected parts of the plant turn brown and die off.

Control measures. Begonias should be sprayed with a fungicide solution, such as topaz solution. The infection is contagious; all flowers in the room (on the balcony) should be treated. Repeat the treatment after 10 days.

Gray rot. Brownish translucent spots appear on the leaves or stems. Over time, a gray bloom appears on them, the spores of the fungus become noticeable. If left untreated, the plant will die.

Control measures. Begonias are sprayed with 0.2% foundationol solution (2 ml per liter of water) or 0.1% topsin solution (1 ml per liter of water). Repeat spraying after three weeks until complete recovery.

Spots on begonias. Sometimes spots of various shapes and colors appear on the leaves and stems of begonias, dark brown or glassy-oily. They can be of bacterial or fungal origin, when the infection penetrates the soil or the spores are carried in the air. And sometimes spots are caused by a banal violation of care - excessive watering, thickening of plants on the windowsill, poor soil aeration.

Control measures. First, remove all the affected parts of the plant, cut off dry shoots, leaves with spots. Then check the soil with your finger at depth. Is it too raw? Adjust watering, loosen potted soil, make sure it is not too cold or dark. If the conditions of care have returned to normal, and there is no improvement with the begonia, new spots appear, it is worth trying the treatment with fungicides, you can apply 'Bona Forte' or 'Topaz'.
