To date, there are more than 400 varieties of tuberous begonia. This is a very beautiful plant that affects everyone with its unusual flowering. Some of the plants are quite lush, a bit like roses, and some differ in very modest small flowers, but with unusually beautiful foliage.
When is the best time to sow?
The popularity of tuberous begonia is growing more and more, and gardeners are trying to propagate it in different ways. This can be done with the help of cuttings, and using tubers. However, the most common variant of growing this plant from seeds. In this case, you can get a flower that will have all the "parental qualities."
Experts recommend planting tuber begonia seeds in the winter. The most favorable time is January or February.
If the owners plan to plant the grown beauties right in the garden, then sowing seeds is best in the last days of February. After all, if you do this earlier, then by May, when it will be possible to plant the plants in open ground, the seedlings will be too large. Sometimes such babies simply die after a transplant.
Those who plan to breed begonias in order to store them in greenhouse or room conditions need to know that they sprout quickly enough, so work with seeds is worth the beginning of December. This will help to get a healthier plant, and by the autumn it will form a powerful tuber, the diameter of which can grow up to 3 centimeters. If you sow the seeds at the end of winter, then the tuber formed by autumn will be very small, up to 1.5 centimeters. With it, the plant may simply not survive the winter.
If we talk about growing begonias from seeds, then this is quite a hard job, which requires a lot of attention from a person, as well as effort. Be sure to take care not only of the time of planting, but also prepare the planting material for sowing. In this case, all agrotechnical rules must be observed. Only in this case the grown seedlings will be healthy and beautiful.
Seeds can be bought at any flower shop or simply ordered online, where there are many offers to buy. However, some gardeners try to grow them themselves. So you can get a plant with those flowers that you liked the most.
The seeds of the tuber begonia are very small, and without a magnifying glass they are difficult to see. The fruit, where they are, is a completely small box. Its size does not exceed 2 centimeters, however, it contains approximately a thousand seeds.
In addition, you need to know that begonias, which have double flowers, can give seeds only as a result of artificial pollination. To implement it, it will be necessary to transfer pollen from female flowers to female flowers. She gathers from the stamens. Often in rather thick "terry wilds" it is not possible to find male flowers, since they turn completely into petals. This usually happens only with the very first inflorescences, all subsequent ones will have pollen on the inner edges. You can collect it using a regular brush for painting. Then the pollen must be carefully transferred to the female flowers. This should be done at least 3 times a day for 3 days.
If as a result of a job well done, pollination was obtained, then the seed box of begonia will not disappear, but will continue to form. Ripening seeds lasts for 1.5-2 months. In many respects, it depends on the temperature in the room or on the street, as well as on the length of the day. If the plant is outdoors, then with a cold snap the begonia must be brought into the room so that the seeds can ripen faster.
After the seed box changes color and becomes brown, it must be cut off and put into storage in paper. When the seeds are fully ripe, they can be used for their intended purpose.
If you want to get only terry beauties into your collection, then you do not need to plant them near plants with simple flowers. When planting a plant on the street, you need to know that begonias, next to simple flowers, produce a large amount of pollen. It can be carried not only by bees, but also by birds, which means that it can get on terry begonias, and as a result the plant will turn out to be ordinary.
Preparing for sowing seeds of tuber begonia, you must definitely think about the substrate for it. The soil should be slightly acidic, since these plants do not tolerate acidic soil at all. To date, in specialized stores you can purchase soil individually for each plant, so there will be no problems with this. However, if there is no possibility or time to go to the store, then you can make a substrate at home. To do this, you need to mix leafy humus, sand, perlite and turf in equal proportions.
Both purchased and home-made land must be decontaminated. Indeed, almost all begonias are susceptible to fungal diseases. To carry out this procedure, it is necessary to freeze the substrate. To do this, you need to hold it for some time in the cold. When it completely freezes, it will be ready for use.
In addition, some gardeners simply very carefully water the entire substrate with boiled water. This will help not only to disinfect it, but also to get rid of possible weeds.
You can also use a solution of manganese. To do this, pour the earth with a very weak mixture of manganese and put it on a water bath for several minutes so that it is steamed well.
However, there is an even simpler option for sowing seeds. To do this, it is enough to purchase special tablets from peat and sow begonia seeds in them.
How to properly land?
Not every gardener knows how to properly plant seeds at home. Begonia seeds are quite small, so in order to make your work a little easier, you need to mix them with sand. You can just sow them, or you can press each seed directly into the substrate, which is necessary to moisten first.
After this, the container with seeds must be covered with a thin glass or a dense film. Then it needs to be moved to a place warmer, for example, put near the battery. The temperature should be in the range of 21-25 degrees. When it is below this indicator, the seeds may not even hatch. After 20-25 days, the first sprouts will appear.
For those who decide to plant seeds for the first time, it is best to use granular seeds, which will be much easier to work with.
In addition, peat tablets can be purchased so that during the transplantation not to damage the root system of young seedlings. It is worth considering this process in more detail.
First, tablets should be put in a container of water so that they are filled with moisture. When they exceed their volume several times, you can put seeds in the resulting hole. Then the container with tablets should be covered with glass. After a certain time, the container must be opened and aired for some time. In addition, using granular seeds, you need to know that it will take a little longer to grow them, since you need to wait until the shell dissolves completely. You also need to consider that not all seeds can germinate, so you need to take a little more.
To grow healthy seedlings, it is equally important to provide sprouts and subsequent care. Literally in 2 or 3 weeks the first shoots will appear. They immediately need to provide a large amount of light so that they do not stretch upward. To do this, the container with the sprouts that have appeared should be placed closer to the window and slightly lower the temperature in the room, to about 17 degrees.
When young shoots appear 3 or 4 leaves, you can pick them in separate small pots, the volume of which should be no more than 50 milliliters. It can be ordinary plastic cups, at the bottom of which you need to make holes, or purchase small containers in flower shops. It is necessary to place a rather fertile substrate in them.
When the picking of the last plant ends, they all need to be placed back in an impromptu greenhouse. Accustoming to fresh air should be done gradually. In addition, at first they need to be protected a little from direct sunlight. When the leaves of young begonias begin to sink, the greenhouse should be covered immediately so that the plant does not completely disappear.
Pick-up can be carried out up to 3 times, however, this procedure must be done very carefully. After the seedlings are fully hardened, and the root system is well strengthened, they can be transplanted into flowerpots “for permanent residence”. Place them on the east side, but you need to protect the leaves from direct sunlight.
To grow a full, healthy plant, it is very important to fertilize begonia. The first top dressing is carried out only at the moment when the last pick is made and the plant is transplanted into separate flowerpots.
Fertilizer is most often applied in a complex, with an interval of 2 weeks. This will allow the plant to not only look healthy, but also significantly increase flowering.
It is best to apply fertilizers in which there will be both potassium and phosphorus. But making fertilizing with nitrogen fertilizers, you can only achieve leaf growth.
In addition to chemical fertilizers, you can try using folk remedies. For example, using conventional yeast for top dressing, you can achieve the same effect as when processing with phosphorus or nitrogen fertilizers. To do this, it is enough to dilute 1 gram of yeast in 1 liter of water and add 1 teaspoon of granulated sugar. When it is infused for 3 hours, it is diluted with water in a ratio of 1: 5 and watered begonia. Such top dressing is done no more than 5 times a year.
When germinating seedlings, the earth must be constantly moistened. However, zeal is still not worth it, because the roots can become rotten. If seedlings are grown in tablets, then watering should be carried out through a pan. Be sure to ensure that they do not dry out.
Subsequent watering is carried out depending on the time of year. So, in the summer you need to do it every other day, but in the winter it will be enough once a week. Water must be soft and warm.
To summarize, we can say that begonia from seeds can be grown even at home. The only thing she needs is good care.
