Proper Tuberous Begonia Growing Guide for Beginners

A beautifully flowering house plant, tuber begonia (Begonia tuberhybrida) is a member of the Begonia family. It was bred by crossing, and at least seven species were involved.

 This plant is represented by both simple and terry varieties, while the color of the flowers varies from bright red to snow-white. Allocate both ampelous and bush forms of tuberous begonia.

The dormant period of such a flower is pronounced. Moreover, when the bush is at rest, there is a complete dying off of its parts located above the ground.

 In mid-July, begonia blooms actively. On one bush, both female and male flowers are formed. The life span of one flower is from 10 to 15 days.

 If you care for the flower correctly and create suitable conditions for it, then it will bloom for a very long time and without interruption throughout the entire growing season.

This perennial needs regular rejuvenation. It is distinguished by its rapid growth: within a year, the bush can become 3 times larger. Flowering is observed throughout the year, except for the winter months, when the plant is resting.

    Brief description of cultivation

    1. Temperature conditions . Best of all, such a flower feels at an air temperature of 20 to 25 degrees.
    2. Air humidity . Needs regular moistening from a spray bottle.
    3. Illumination . A large amount of bright light is needed, which must be diffused. Need protection from direct sunlight.
    4. Watering . Moisten the potting soil abundantly after the top layer dries.
    5. Substrate . It should be moisture-consuming, loose and nutritious.
    6. Fertilizer . During that time, while the bush is blooming, it is fed with a mineral complex for flowering crops.
    7. Transplant . It is carried out once a year at the end of the dormant period.
    8. Reproduction . Cuttings, seeds and dividing tubers.
    9. Features of care . If the bush feels an acute lack of moisture and nutrients, then instead of double flowers, simple ones can form.

    How do you take care of tuberous begonias?

    To ensure proper development of tuberous begonias and lush flowering, you need to try to create optimal conditions for growth and avoid mistakes in care.

    The flowering of such a spectacular plant in indoor conditions lasts until the last days of October. Moreover, it depends on the growth conditions what the male flowers will be: double or simple. 

    Double flowers either do not have stamens at all, or there are very few of them. This can cause pollination problems.

    To harvest the seed, the parent shrub should be planted in a substrate with a minimum of nutrients. Thanks to this, simple flowers will form on the begonias, the anthers and stamens of which will be excellently developed.


    In order for the development of the bush to occur within normal limits, it is necessary to provide it with a constant moderate air temperature in the room: 22-25 degrees. On hot days in summer, the plant begins to bloom less abundantly, while it grows more slowly.

     This is due to the fact that the bush is under stress. At this time, it is recommended to move it to the garden if possible and choose a place for it in the shade of a tree.

    Air humidity

    If high humidity is maintained in the room, then thanks to this, the bush will grow more quickly and bloom more luxuriantly. However, it is forbidden to moisten the plant itself from the sprayer. If water droplets fall on flowers and foliage, brown specks will appear in these places. To safely and effectively increase the humidity of the air, it is recommended to place an open vessel filled with water next to the flower.


    For tuberous begonias growing in indoor culture, it is important to provide plenty of bright, diffused light. In this case, the direct rays of the sun should not fall on the flower. A southwest or southeast window sill is best suited for it. At noon, the bushes must be protected from the bright sun. If you neglect this rule, then sunburn may appear on the foliage.


    It is necessary to moisten the soil mixture in a pot with begonia abundantly. However, make sure that no liquid stagnates in the roots. Even if the substrate is waterlogged once, this can cause rot on the base of the stems or tubers. The bush should be watered with well-settled water, the temperature of which is slightly higher than room temperature.

    For the cultivation of such begonias, a loose, moisture-consuming and fertile soil mixture is suitable. To prepare the substrate with your own hands, you need to mix river sand, humus and rotted leafy soil (1: 1: 4). If you wish, you can buy a soil mixture in a specialized store, which is intended for the cultivation of begonias.

    Top dressing

    To improve growth and flowering, the bush must be systematically fed: during the growing season, fertilizer should be applied to the substrate only two or three times. For this, a complete mineral fertilizer for flowering crops is suitable.

    Tuberous begonia transplant

    Proper Tuberous Begonia Growing Guide for Beginners

    Tuberous begonia is transplanted in the last days of February. At this time, the tubers are still hibernating. Carefully remove the tubers from the soil mixture and trim off any remaining roots. Then they are planted in a new substrate.


    Since the last days of October, there has been a gradual dying off of the part of the bush located above the ground. When all the leaf plates fall off, the potting medium is no longer watered. 

    Completely dried stems must be cut off, and then the container with tubers is rearranged in a place where it is always cool and dry. They will stay in this place until the end of winter.

    How to propagate tuberous beginia from cuttings 


    Proper Tuberous Begonia Growing Guide for Beginners

    Tuberous begonia can be propagated by cuttings. Well-developed lateral shoots are suitable for this. For rooting, they are planted in a substrate or placed in a glass of water. When planting in a soil mixture, the segments are deepened by 20–30 mm.

     In order to prevent the appearance of rot on the cuttings, the surface of the soil mixture is sprinkled with a thin layer of river sand, which must be pre-calcined.

    The planted sections from above must be covered with a plastic bag or a glass jar. The first roots should appear after 15–20 days. It is best to cut begonia in spring and early June.

     Tuberous begonia growing from seeds

    Proper Tuberous Begonia Growing Guide for Beginners

    To grow such a crop from seeds, they should be sown in February – March. The substrate is used moisture-consuming and loose. Spread the seed material over the surface of the soil mixture and then moisten it from the sprayer.

     From above, the crops should be covered with a transparent film or glass. Until the first seedlings appear, the crops are provided with constant heat (from 24 to 27 degrees).

    Provide crops with systematic moistening from a sprayer with warm water and ventilation. As a rule, the first seedlings appear after 1.5–2 weeks. As soon as this happens, the crops are harvested in a cooler place (from 18 to 20 degrees). Plants are picked twice. 

    When the second leaf plate appears, the bushes dive for the first time. And this procedure is repeated after 20-30 days. After the bushes have a height of about 10 centimeters, they are transplanted into individual small containers.

     The beginning of active growth of tubers near seedlings occurs in the first autumn weeks. If everything is done correctly, the tubers by the beginning of the dormant period will have a size of about 15 mm.

    Possible problems

    Proper Tuberous Begonia Growing Guide for Beginners

    1. Falling foliage . The room is too cold.
    2. Withering of leaf plates . Tuberous begonia is experiencing an acute moisture deficit.
    3. The bush blooms poorly . The plant lacks nutrients and may be too dark. Apply fertilizer to the substrate and transfer the bush to a more suitable location.
    4. The foliage dries up and loses its turgor . The excessively low air humidity and heat in the room are to blame for this.
    5. Yellowing of the leaf plates . The room has high humidity and is too cold.
    6. There are small whitish spots on the foliage . This is a sign of powdery mildew development.
    7. There are specks of brown and black on the foliage . The bush is affected by a bacterial disease. It must be sprayed with a solution of a fungicidal preparation.
    8. The foliage is rotting . This is due to the stagnation of moisture in the substrate and the ingress of water droplets onto the leaf plates.
    9. Pests . Most often, aphids, spider mites and whiteflies settle on such a flower. To destroy them, you will need insecticide treatment.
