Origin and botanical description
Homeland of naked begonia - tropics of Central and South America... It grows on moss-covered tree trunks on rocks. This representative of the flora easily adapts to local climatic conditions, is unpretentious.
The length of the shoots reaches 50 cm. The leaves are shiny, glabrous, oval. Pointed at the apex, serrated at the edges. Leaves grow on both sides of the stem in the same plane.
Appearance and features
Naked begonia is characterized by creeping bare shootsthat take root at the nodes. Leaves are light green, growing on short stalks (2cm). The length of the leaf plate is 9 cm, the width is 7 cm. Features of the plant:
- Small white flowers.
- Male flowers have 4 petals, female flowers have 5.
- The inflorescences are drooping, multi-flowered, racemose.
- Reddish petioles.
- The bare peduncle is 8-10 cm long.
Reference! Male flowers in naked begonia are much smaller than female ones.
Naked begonia blooms from January to April.
Such a beautiful and unpretentious plant is decorative deciduous, tuberous, flowering or bushy. A huge number of varieties and types of begonias are actively used by flower growers for growing, both at home and in the garden. Read about such varieties - Diadem, Sizolistnaya, Mix, Bauer or Tiger, Collar, Coral, Fista, Mason, as well as terry, with yellow flowers or bright red leaves.
Where and how to plant?
Lighting and location
When cultivating in the open field, light areas are selected, well protected from direct sunlight.
Scorching rays of the sun are contraindicated for begonia - their delicate leaves are susceptible to burns.
When growing bare begonias as a houseplant at home, the windows are shaded from ultraviolet fluxes.
Indoor flowers feel comfortable on the western and eastern windowsills, where the sun is not as bright as on the southern windows, but also lighter than on the northern ones.
Begonias need light, fertile soil... There are ready-made substrates on sale, which include perlite and peat. You can make your own potting mix. To do this, mix:
- sand 1.5 part;
- turf 1 part;
- leafy ground 2 parts;
- peat 0.5 parts.
The acidity level of the soil is not more than 6pH.
Begonia seedlings are placed on the garden plot no earlier than the beginning of June.... Before planting in open ground (6-7 days), the planting material is hardened. It is placed in a bright room, observing the temperature regime: during the day + 23-27 degrees, at night up to +15 degrees.
- Make holes for each plant at 20-35 cm intervals (based on the size of the seedling).
- Carefully place the bushes in the planting holes.
- Sprinkle the base of the stem with earth.
- Top up with ash.
Important! Before planting, it is recommended to apply potash-phosphorus fertilizer to the soil.
If begonias are planted at home in pots, then they should be with drainage holes. Before use, the containers are washed, disinfected with potassium permanganate, rinsed and dried. Then the following actions are performed:
- A drainage layer is laid on the bottom of the pot: broken brick, expanded clay or pebbles. The drainage should take up a third or a quarter of the pot.
- Pour the substrate on top.
- Place a seedling and fill the free space with earth.
For begonias, use wide, but shallow pots.
How to care?
The herbaceous culture that grows at home loves consistency. Containers with flowers should not be rearranged.... It is better to immediately identify a comfortable place. In order for the bush to form correctly, it is periodically turned.
Temperature and humidity
Begonias feel good at temperatures from +18 to 20 degrees. Higher temperatures are also tolerated in summer. In winter, the thermometer should be at least +15 degrees.
Begonias need to maintain constant humidity.... Only the air around the flower is irrigated, but not the leaves. You can install a tray with a pot on a tray with wet moss or expanded clay.
In winter, the hot radiators are covered with a wet towel. This increases the humidity in the air.
How to water?
Indoor plants prefer measured watering. You need to focus on the state of the soil layer. If it has shrunk by 15 cm, it means that the begonias need moisture.
- Moisturize at least 2 times a week in the phase of active growth and flowering.
- In the fall, the intervals between waterings are increased.
- In winter, moisture is reduced.
Water for begonias should be at room temperature, clean and soft.
Tap liquid cannot be used immediately.... It must be filtered or boiled, and left to stand for at least a day.
It is advisable to loosen the topsoil by 1 cm after watering, when the earth dries up.
Naked begonia during the growth period is fed twice a month with sodium humate, formulations with a high nitrogen content. As development progresses, mineral fertilizers are applied once a month. From the moment of flowering, the culture is fertilized with potassium-phosphorus mixtures. This will positively increase the number of buds and prolong flowering.
- Garden begonia is watered regularly and abundantly, especially in dry weather.
- Fertilizers are made by alternating mineral and organic fertilizers.
- They fight weeds, loosen the soil.
- With the onset of frost, the deciduous crop is dug up, planted in a pot and kept in room conditions.
Common diseases and pests
As a result of excessive watering and humid air, lack of moisture, begonias develop various diseases:
- Gray rot... White spots with a gray bloom appear on the leaves and tops of the shoots. Treatment: treatment with 1% solution of Bordeaux liquid.
- Powdery mildew... The leaf plates are covered with a white coating. Treatment: spraying with fungicide.
- Bacterial spot... Watery spots form on the underside of the leaf. The disease cannot be cured. The affected specimen is destroyed.
Begonias can be attacked by aphids, a false shield, or a spider mite. For pest control, drugs are used: Karbofos, Atellik, Derris, Decis.
Naked begonias can be easily propagated by stem cuttings in soil or water, as well as by leaves. Cutting is the most reliable way to grow a new flower.
- Cut a strong, healthy stem 8 to 12 cm long.
- The stalk is divided into parts if you need to get several plants. Each fragment should have at least 2-3 buds.
- Leaves, buds and flowers are removed from the shoot. 1 or 2 leaves are left at the top.
- The planting material is placed in water for rooting.
The cuttings are placed in a place protected from direct sunlight with a temperature regime of + 20-22 degrees. After the appearance of roots 1-2 cm in length, the shoots are planted in a specially prepared substrate.
Several new begonias are grown from one leaf.
- The largest leaf is found on the mother flower. It is cut off with a razor blade or sharp knife.
- On a horizontal surface, the sheet is divided into segments. Each must contain at least one vein.
- River sand is poured into a box or pot and watered.
- Fragments of sheets are laid out on the surface of the sand.
- The container with the planting material is covered with polyethylene and placed in a bright place.
- To prevent the soil from drying out, it is periodically moistened with a spray bottle.
- Young plants are planted in pots after 3 months.
Decorative deciduous begonias are grown from seeds.
Planting material can be sown one by one into peat tablets.
- Planting is carried out at the end of February in prepared soil.
- Seeds are not sprinkled with earth.
- A greenhouse is created on top: covered with foil or glass and placed on a lighted windowsill.
- The land with seedlings is periodically sprayed.
- When the seeds germinate, the cover is removed to harden the seedlings. Over time, the greenhouse is removed.
- After the appearance of 2-3 young leaves, the seedlings are transplanted into a large container.
- After 2 months, begonias dive into pots or flowerpots.
- In spring, when transplanting, a large bush can be divided into 2 parts and planted in pots.
In order for naked begonia to grow and develop well, you need to follow simple rules of care, ensure comfortable conditions of detention: do not put in the scorching sun and in a heavily shaded place, take measures to combat diseases and pests.
