Griffith's begonia belongs to the ornamental-deciduous type. The culture is distinguished by its spectacular appearance - leaves of an unusual shape, a unique color of flowers.
To make the flower feel comfortable at home, it is provided with proper care and prevention of diseases and pests.
How this plant looks and how exactly to care for it so that it pleases with its appearance will be described in detail in this article. It also talks about what diseases of this begonia can be encountered and what to do with it.
Botanical description and origins
The Latin name of the plant is Begonia Griffithii. Begonia Griffith is characterized by an adjacent short stem up to 45 cm in length. Leaves are oval, slightly wavy at the ends, growing on long petioles. The color of the leaf plates is unusual: a reddish middle with a light green zone, a wide silvery edge along the edges. The flowers are large, pinkish-pale.
Begonias were discovered by the French botanist and monk Plumier. He gave the name to these plants in honor of M. Begon, the organizer of the expedition. Much time has passed since then. During this period, scientists have discovered many species, including the Griffith begonia. The birthplace of the flower is the Eastern Himalayas.
Appearance and features
The height of an ornamental leafy culture reaches 30-50 cm... Stems are recumbent, short and thick. Characteristic features of the Griffith begonia houseplant:
- The edges of the leaf plate are wavy or crenate.
- The lower part of the leaves and stems are covered with hairs.
- On the pedicels there are male and female flowers.
- In female flowers, a triangular seed capsule is formed above the petals.
The leaves are velvety and dense, ovoid, asymmetrical, covered with purple-red hairs.
Decorative deciduous begonias are grown at home.
Lighting and location
It is necessary to arrange flowers in a moderately warm, sunny room.... Begonia Griffith loves rich, diffused light, but it can also be in partial shade. Containers with plants are placed on the southern or western windowsills. It is not advisable to put on the northern windows. The culture should be protected from direct ultraviolet rays so that the leaves do not get burned. The windows are covered with curtains or cardboard is installed, reflective film is glued on.
What should be the soil?
Begonias are planted in loose and fertile soil. with weak or neutral acidity. To prepare a good substrate, mix one part at a time:
- Turf and leafy ground.
To make the soil moisture and air permeable, add perlite, coconut fiber and other leavening agents. To reduce acidity, charcoal is poured into the soil.
The container should be wide, but not deep... The material does not matter: plastic, glass or ceramics. At the bottom of the pot, drainage holes must be made to provide air access to the roots and to drain excess liquid.
Drainage (fine gravel, expanded clay) is poured at the bottom of the pot, 2-3 cm of charcoal is poured on top. The seedling is placed in a bowl and sprinkled with the prepared substrate. So that voids do not form, the soil is lightly tamped.
How to care?
Since Griffith's begonia is native to the Himalayas, it prefers a humid microclimate. When the air is dry, a humid atmosphere is created by spraying the area around the plant. To increase the humidity of the air, another method is used:
- Place expanded clay or pebbles on a pallet.
- Place the pot on top.
- Add water periodically.
Attention! Do not sprinkle the leaves with water.
Begonia Griffith loves warmth, but does not tolerate strong temperature changes... The optimal thermal regime for decorative deciduous culture in summer is + 22-25 degrees. In winter, at least +20 degrees.
The plant does not tolerate stagnation of moisture in the pot - the root system will begin to rot. Too dry soil is also not acceptable. Watering rules for Griffith begonias:
- Systematic moistening 3-4 times a week as the soil layer dries up.
- In the heat, the frequency of watering is increased.
- In the autumn-spring period, moisture is reduced.
- Water for irrigation is used only boiled or filtered. You can acidify a little.
The liquid should be at room temperature.
Begonia Griffith does not need additional feeding... The main condition for the supply of nutrients is planting and transplanting into fertile soil, consisting of leafy soil, turf, peat and with the addition of needles and sand.
Specificity of care
Begonia Griffith needs to be transplanted every year (in the spring) into a larger container. In a small pot, the culture loses its decorative appearance: the leaves begin to fade. Transplanted carefully, keeping the root ball.
After transplanting, pruning is carried out with a sharp knife (but not with pruning shears) to correct the shape of the bush. Due to insufficient light and low humidity, the Griffith begonia is transferred to a dormant state from October to February.
As a result of improper care, the culture can get sick... Keeping begonias on the balcony is risky. Open air gives access to diseases and harmful insects. During the growth period of deciduous begonias, the following problems arise:
- Yellowing of leaf plates due to excessive or insufficient moisture.
- The appearance on the leaves of a gray bloom or brown spots. Solution: pruning the affected area and treating it with a fungicide. Preventive measures: adherence to the ventilation regime, control of air humidification.
- Falling leaves due to lack of lighting.
- Leaves develop brown tips due to low humidity.
Important! Leaf diseases can provoke the death of a plant if action is not taken in a timely manner.
The most common diseases of begonias are:
- Gray rot... At the top of the plant, the leaves appear gray watery spots. In the future, this leads to rotting and breaking of the stem. Treatment: processing the flower with Bordeaux liquid or copper-soap composition.
- Powdery mildew... Round spots with a white coating are formed on the sheets. To eliminate the problem, use Fundazole solution.
- Bacterial and ring spot... Yellow-green lines or spots appear on the plant.
Spot treatment is not possible. It is recommended that the infected plant be destroyed to prevent others from getting sick.
Begonias are affected by insects: greenhouse aphids, soft pseudo-scale insects, greenhouse thrips and others. To control pests, they use two methods: mechanical and chemical. The first is to collect insects when there are not very many of them. The second consists in the use of various decoctions and preparations for the destruction of harmful insects. Effective pest control agents are:
Plants are treated with chemicals in a well-ventilated non-residential area or in the open air.
Griffith's begonia is bred in several ways: by seeds, by separating bushes or rhizomes, by cuttings, by leaves or parts thereof.
Seeds are sown at the end of February in special soil... The planting material is pressed into the ground, but not sprinkled. Moisten with a spray bottle and cover with glass or film. Seedling boxes are placed on the windowsills. The room is kept at a temperature of at least 20 degrees Celsius. After 6 weeks, the sprouts are dived into separate pots and kept in a lighted place.
Splitting the bush:
- The plant is removed from the vessel.
- Overgrown stems, large leaves and peduncles are cut off.
- The roots are washed from the ground.
- With a knife, a bush or root is divided into fragments so that there is a sprout or bud on each part.
- Sprinkle the cut with coal.
- Place the planting material in a pot.
For propagation by cuttings, a cut of 10 cm is cut, the slices are dried. A hole is made in a container with a substrate and a cutting is placed, deepening to the leaves.
To grow begonia from a leaf, choose a large, healthy leaf. and cut it into several pieces. Each piece should have a streak. Parts of the leaves are placed in a bowl with sand or soil. Cover with a plastic lid or foil. The planting material is periodically moistened.
Thus, even a novice florist is able to grow Griffith's begonia. When all the rules of care, light and heat conditions are observed, deciduous culture pleases with its luxurious appearance.
