Tuberous begonias are planted in pots and outdoors. In order for a decorative culture to please the eye with beautiful flowers, it is important to plant it correctly and provide competent care. All this will require knowledge of certain subtleties from the gardener. This will help you understand the following questions: when and under what conditions you need to transplant a tuberous begon, how to properly plant a flower in open ground and in a pot, why begonias need a transplant and how it is carried out, as well as what care a plant planted at home or in a garden requires.

Conditions and time

To plant a crop in open ground, you need to wait for warm, stable weather in late May or early June. The night temperature should not drop below +12 degrees. When choosing a place for begonias in the garden, two factors are guided: practical and aesthetic. Plants are planted in a visible, bright area, well protected from wind and direct sunlight. Bright lighting causes leaf burns.

Ideal for planting begonias next to bushy plants that will cast shade. If there is no such place in the garden, arrange artificial shading - put a canopy from a fine mesh.

Attention! Begonias are very demanding on the soil.

The soil on the site should be with a low level of acidity, fertile, loose. Shouldn't be nearby:

  • Willow or oak. Trees saturate the ground with tannins, which have a detrimental effect on the development of begonias.
  • Big stones.
  • Dense soil layer.

If the land is "poor", add humus, bird droppings or other organic matter. You can prepare the soil by mixing 2 parts of peat and leafy soil and part of coarse sand. After a week, you can plant the plants. Tuberous begonias begin to be planted in pots in late February, early March.

How to plant correctly?

Potted room

Flower containers are suitable from any materials: plastic, glass, ceramics... The containers should not be deep because begonias have a shallow root system. For planting, you can buy a ready-made substrate or prepare it yourself by mixing 2 parts of leaf humus with a part of peat and sand.

You should work with the planting material carefully: do not drop or press on the tubers.

Potting scheme:

  1. Place the dishes on a tray.
  2. Be sure to lay drainage on the bottom of the tank: expanded clay, broken brick or clay shards.
  3. Add soil. The surface should be 3-4 cm below the edge of the pot.
  4. Make a depression in the center and plant the tuber.
  5. The planting material is placed in the ground with the convex side. The third that is on top should remain on the surface.
  6. Sprinkle with earth only after the first shoots appear. The place for the growth of begonias should be bright, but protected from direct UV rays and drafts. Temperature range - from 15 to 17 degrees Celsius.

For flower beds in open ground

From the end of February, you can purchase planting material for growing in the garden. Tubers should be dense and even, brown in color, free of mold and plaque. They are stored in a cool place until planting.

Before planting, the dead roots are cut off from the tubers and placed 3/4 in warm water with the addition of a fungicide for half an hour.

Algorithm for planting tuberous begonia in a flower garden:

  1. Prepare grooves for planting material, based on the size of the tubers. For massive, the optimal distance is 30 cm, for medium - 20 cm, for small - 15 cm.
  2. Pour ash and humus into the pits.
  3. Moisten the soil slightly.
  4. Place the tubers in the holes and cover to the base of the shoot.
  5. Planting is mulched with a mixture of ash and humus.

Subtleties of transplant

When is it needed and when is it carried out?

When the rhizomes begin to look out of the drainage holes, the plant must be urgently transplanted into another container. Begonias are transplanted in other cases as well.:

  • The leaves turned yellow.
  • There are signs of the disease.
  • The earth turned sour.
  • The dishes have gone bad.
  • The flower is flooded.

Attention! The transplant is carried out in the middle of spring.

What to do?


  1. The flower is carefully removed from the pot.
  2. Rhizomes are cleared of earth.
  3. The root system is immersed in a weak solution of potassium permanganate for 20 minutes.
  4. All rotten roots are cut off and the cuts are treated with charcoal.
  5. A new substrate is poured into a container larger in size than the previous one and a plant is planted.

After transplanting, the culture will hurt for a while.... In a new pot, it will take root only after 2 weeks.

How to care?

At home

Containers with plants are placed in a bright place, avoiding direct sunlight. The optimal location is window sills on the east or west side. The windows are hung from the strong sun.

Rules for watering begonias after planting in a pot:

  • Humidification with warm boiled or settled water.
  • Water at room temperature 3 times a week. In the heat - every day.
  • Avoid getting moisture on the leaves.
  • Make sure the ground is dry before wetting.
  • After flowering, gradually reduce watering.

Attention! Watering should be moderately moist.

The optimum temperature is at least + 20-22 degrees. In winter, at least + 15 (you can find out how to properly preserve tuberous begonia in winter here). Begonias need complex nutrition. Once every 2 weeks, they are fed with mineral fertilizers, alternating with organic matter.

When budding ends, the ground part is cut off, the pot with tubers is placed in a cool place until spring and stored at a temperature of plus 10 degrees.

In the garden

Features of caring for tuberous begonia on the street:

  • Systematic watering after drying of the soil with settled water.
  • Weed weeding.
  • Fertilization with potassium-phosphorus compounds, ash, humus every 2 weeks from May to October. From August, fertilizers are stopped so that the plants are prepared for winter.
  • Pinching the top of the stem after reaching a length of 12 cm to stimulate the development of lateral shoots.
  • Outdoor begonias need abundant watering, especially in hot weather. Water stagnation should not be allowed. Watering is best in the morning. It is not desirable that moisture gets on the stems, leaves and flowers. The sun's rays can cause burns.

    Excessive moisture leads to rotting of the root system and the death of the culture (read about why tuberous begonia does not bloom and what to do, as well as what diseases can destroy plants, read here). Description, prevention and treatment of plant diseases.

  • The shoots of plants are very brittle, so they are tied to a support. It is advisable to remove wilted flowers from the bushes.
  • When the herbaceous culture grows rapidly, shoots and foliage are pruned. When the stems are stretched to 8 m, the shape is corrected: excess shoots are removed from the sides to give the bush the desired appearance.

    Do not use garden shears for pruning as begonia is a very delicate plant. For work, only a sharp knife is suitable.

  • After pruning, it is recommended to sprinkle the damaged areas with charcoal for quick recovery.
  • With the onset of autumn, watering is gradually reduced. Rhizomes are dug out before the onset of the first frost. The green mass is removed, the roots are trimmed, disinfected with a fungicide. It is dried, placed in peat and stored until spring in a cold place.

Thus, tuberous begonias are planted in open ground with the onset of heat. At home, no later than March. It is important for plants to ensure regular watering without waterlogging. Feed constantly - from the moment of planting until the end of flowering.
