In the article we will tell you what types of royal begonias are, how to properly care for the plant at home, and what diseases and pests can affect the plant.
Botanical description, history of origin, how does it bloom?
Perennial shrub with hanging shoots. Asymmetrical leaves can reach 120 mm, have an elegant, but slightly oblong shape, the surface is smooth. On the one hand, the plant is red, and on the other, greenish with dark shades at the edges of the leaves. Coral-red flowers with a diameter of 1.5 cm are located only in groups, usually collected in a racemose inflorescence.
The flowers of the plant are unisexual. Blooms in the summer. Around 1956 in London at an auction among orchids, a new type of flower appears - the Royal Begonia. A little later, breeders bred dozens of different varieties. Since then, the plant has evolved into many hybrid species. The plant was crossed with Asian species. Why the royal begonia remained the progenitor of all common varieties.
Other names for the houseplant "Rex"
The classic name is Begonia Rex-hybrid or Begonia Rex Cultorum. Some of the well-known Rex begonias have become known in the world several centuries ago: Begonia rex 'Abel Carriere' was bred in 1878 and can grow safely in our apartments to this day. Over such a long time, more than a hundred varieties have appeared. Gradually, the Rex group began to include hybrids, the parent (wild) species begonia rex in whose genetics was not at all, which significantly distinguished this group.
Types and their photos
Ornamental begonia has no aerial stems at all, and pubescent leaves instantly grow from a branched root. This type of plant is able to amaze with its unusual beauty. Begonia leaves have different shapes and colors (read more about decorative deciduous begonias here). The leaves are painted in different colors:
Leaves can be monochromatic, multi-colored, speckled and with edges.
The royal snail begonia is a hybrid species. It has rounded leaves up to 300 mm long with small denticles at the edges. The color of the leaves is brown, purple, violet. They are painted with a pale green, white, silver border.

Where and how to plant it?
Royal begonia should be grown at home, requires special care. The first thing to consider is the normal room humidity. It is recommended to place plant pots on pallets with expanded clay or gravel. It is advised to place dishes with water next to the dishes, but or install a small fountain.
It is not recommended to spray the plant - in the areas where drops fall, white spots form, which leads to rotting. Therefore, you will have to wipe the dust with a damp cloth, and preferably a dry one.
Lighting and location
Maintenance usually involves watering frequently and abundantly. Do not overmoisten the soil, as the stems and root system can rot. At the time of leaving, you should take care of the lighting in the room - the plant needs bright and slightly diffused lighting, but you should not put them where direct sunlight falls.
It is better to place the begonia on the windowsill on the west side. In order for the plant to develop well, then with complex care, the temperature indicator should be monitored - it should be 18-25C. Do not place the plant near heaters.
The best mixture for royal begonia soil is leafy soil, humus, peat, sand. They should be connected in a ratio of 1: 0.5: 0.5: 0.5. Drainage should be sprinkled on the very bottom of the dishes. After that, it will be possible to add a mixture of peat and compost, which will help to replace the complex of potassium-phosphorus fertilizer.
Royal begonia is considered a rather delicate plant. Caring for him at home requires appropriate knowledge and experience.
But when caring for begonia, problems often arise:
- The plant refuses to bloom. A similar problem arises when an overdose of additional feeding, with a lack of light and moisture, a temperature regime uncomfortable for begonia, but also with drafts.
- Leaves turn yellow. This means the plant lacks nutrition and moisture. Change the watering time, fertilize constantly, you can try replanting the plant in a different soil. Often, yellowing of the leaves is caused by the presence of pests. And here the transplantation of begonia can help, but the procedure for treating the roots with a weak solution of potassium permanganate should be added.
- Leaves and cuttings begin to rot. In addition to the above reasons, where excess moisture or insignificant absorption of fertilizer play an important role, here you will have to eliminate the fungus that develops in a humid environment. A constant inspection should be carried out, if rot is found, it must be removed.

- Powdery mildew. It appears as a white bloom. It is necessary to treat with a solution of Topaz-type fungicide.

- Ring spots. It appears as a yellow-green spot. It is formed on the tubers of the plant, which is why the infectious begonia should be removed to another place so as not to infect healthy ones. Carriers can be aphids and thrips, which will have to neutralize all pests.
- Bacterial stains. Formed on the lower part of the leaves in the form of watery blisters, which turn brown and then affect the inflorescences, cuttings. The diseased plant will have to be destroyed, healthy begonias must be treated with copper oxychloride.
- Soft false shield. It affects the entire green mass of the plant. Formed in the form of a dark sugary discharge, sooty fungi may appear. The affected area of the plant instantly loses its original shape, while the leaves are affected. Should be treated with garlic tincture.
- Greenhouse whitefly. It usually lays eggs on top of the leaves of the plant, causing discolored areas to appear. You can remove the pest with a solution of laundry soap.
- Gall nematode. It appears as a microscopic worm that infects the root part of the plant. Growths form on the stems of begonia, where the larvae develop. The roots begin to rot, the plant stops growing after it dies. In this case, watered with a solution of heterophos.
- Spider mites and aphids. They can arise anywhere. The formation of traces should be removed. With constant care of the plant, aphids are not formed. You can remove the formation of pests with a weak soap solution. If this option does not help, then onion infusion should be used.
It is possible to propagate royal begonia at home both by seeds and cuttings. Although the plant gets along well from ordinary stems.
- At the time of transplanting begonias in the spring, their reproduction occurs at the expense of the root parts.
- Cuttings should be planted in light soil and at a temperature of 24C.
- The rooted stalk, meanwhile, is covered with a film for reproduction.
- It is allowed to carry out rooting in a bowl with water.
- At the beginning of summer, they propagate at the expense of part of the leaf.
- It is also placed on glass.
- Divide into several parts so that a vein passes through the upper part. All these parts are pressed into the sand.
- To make the cut correctly, you need to start from the bottom of the leaf along a large vein from the branching site.
- For a good touch with the ground, part is tingled with a toothpick in several areas.
- The dishes are covered with foil, then placed in a shade.
- In this case, the room should be constantly ventilated and the soil should be moistened.
- The method of propagation with the help of seeds is not always effective, since the degree of germination is rather low. And only depending on the creation of conditions, and proper care, the plant will live for 2-3 years. It lends itself well to grafting and will continue to exist in the new plant.
Within a month, the first shoots with roots will appear. The first sprouts will be green, the royal begonia receives bright shades only after reproduction as it grows.
