Begonia, also known as begonia, begonia, begonia, glass begonia, etc., is a perennial herb native to Brazil.
soil
Begonia is suitable for growing in fertile, loose and well-drained sandy loam soils. Potted begonia can be a 2:2:1 mixture of garden soil, saprophyll soil and sand.
illumination
The growth period of begonia in all seasons should ensure sufficient light, otherwise it will cause weak and slender plant growth. But at the same time, begonia in all seasons is afraid of strong light, so in the hot summer should pay attention to avoid direct sunlight, move the plant to a ventilated and cool place, otherwise it will cause the leaves to shrink and the edges to scorch.
temperature
Begonia loves warm, humid and semi-shaded environments. Not cold tolerant, avoid high temperature, the suitable growth temperature is 15~25 °C. In winter, plants should be placed on a closed south balcony or indoor light, south-facing window sill, the room temperature should be kept above 10 °C, and the potting soil should be kept moist and dry. If the temperature is lower than 6 °C, the plant is easy to freeze to death. If the temperature can be maintained at about 15°C, the plant can grow and bloom normally.
watering
Begonia is afraid of drying and stagnant water, so it is usually not allowed to water too much, so that the potting soil is too wet for a long time, otherwise it will hinder root respiration, cause rotten roots, cause plant growth to weaken, and the leaf color becomes yellow and white and dull. If rotten roots appear, the light ones can move the pot to a cool place, control the watering, and after a period of time, it can return to normal; In severe cases, the upper part of the plant is cut off to encourage the emergence of new branches.
fertilize
During the growing period, apply well-rotted thin cake fertilizer water every 10 days or so. After the buds are formed, apply phosphate fertilizer every 15 days or so.
