Fitosporin will help you protect the begonia tubers from decay, and Actellik - from various pests. Instead of phytosporin, a solution of potassium permanganate can be used .
The tuberous method of reproduction today is widely used for decorative flowering tuberous species of begonias. Begonia tubers are planted in March, and the tuber should be planted in the sand at half height or a mixture of the same parts of peat, sand and sheet land. Germination should occur at a temperature of about 20 ° C, be sure to regularly water it with warm water. The shoots arising on the tuber should be removed in such a way that at least one leaf remains on the trimmed shoot, otherwise the tuber may well die. Then the cuttings must be planted for rooting. Water them regularly, also monitor the humidity of the earth and air, protect from the rays of the sun. About a month later they are allowed to be transplanted to a permanent place.
So that the places where the shoots were cut off do not decay, be sure to sprinkle them with charcoal powder and dry for 24 hours; then plant the tuber in a pot, however, only the lower part should be sprinkled with earth. When the sprout reaches 5 cm, it must be completely covered with earth.
If the begonia tuber is large and there are several points of renewal, then it is allowed to divide it into two or four lobes. The places of cuts should also be sprinkled for disinfection with crushed coal or greased with brilliant green.
Begonia tubers are planted in a small flower pot, its height should be about 10 cm. Drain from expanded clay should be poured on the bottom of the pot - a layer of about 2 cm. Note that tuber begonia does not like lime, in this regard, it is better to use slightly acidic for planting tubers ready soil "Senpolia".
Begonia tubers can also be planted in a wooden box, which is half filled with a substrate of peat and leaf humus in a ratio of 1: 2, to which a small amount of wood ash is added. The earth needs to be compacted and moistened with a solution of mineral fertilizer. Tubers that are cleaned from the ground are disinfected by putting potassium permanganate in a weak solution for 1 hour, and then placed in a box, between them there should be a distance of 5-7 cm. The box with planted tubers should be kept at a temperature of about + 20 ° C, light, sometimes moistening the soil. Shoots begin to appear after 2 weeks. Planting of begonia tubers in the ground should not occur earlier than the beginning of June, when the danger of frost is already gone.
Planting begonia tubers implies a burial of the tuber no more than 2/3. As the begonia grows, the tuber should only be sprinkled a little. You can simply make a small depression in the ground and put a tuber in it. Now you know how to plant a begonia tuber, but this is not all the subtleties.
Begonia should be watered gently along the walls. For watering, it is better to use melt water. It is also recommended to use lemon juice or a grain of citric acid or table vinegar to soften the water.
You can also say that immediately after planting, when there are still no leaves on the tuber, the substrate remains wet for a long time, and therefore, daily spraying is allowed to be used instead of watering.
