Summer maintenance methods of Rieger Begonia

Rieger Begonia will cause dead leaves and leaves due to changes in transportation and environment, which are often unavoidable. The hot summer is the dormancy period of Rieger Begonia, so conservation needs more attention, otherwise, it is easy to lead to the death of Rieger Begonia.

Rieger Begonia

Management and conservation become more critical as summer progresses. First of all, we should cut off the dead leaves of the flowers (but do not have to cut off the branches), move the potted flowers from the balcony to the cooler windowsill indoors, and strictly control watering, which is the key to safe summer. Many people think that the dead leaves are caused by water shortage, but in fact, it is because the temperature rises, the root water absorption cannot meet the needs of leaf water evaporation, the water supply and demand imbalance, the plant has to protect itself, produce leaves, enter dormancy or semi-dormancy, in order to reduce the demand for water.

At this time, such as increasing the amount of watering, so that too much water in the pot soil, the base of the branches is easy to breed bacteria and rot, and then the tuber inside, the whole plant will die, so at this time must strictly control watering. For example, a flowerpot with a diameter of 15 cm and a height of 13 cm can be infiltrated with 30 ml of water from the bottom of the pot every 10 days or so, so that the pot soil is in a slightly damp state, so that the stem segment of the plant does not rot or partially rot and does not develop downward. As long as the edges of the leaves are withered, but there are still a few young leaves growing slowly, the tuber is not in trouble and the base of the stem is intact.

Four Seasons Maintenance Method of Rieger Begonia

Summer Maintenance of Rieger Begonia

In summer, when temperatures are very high, Rieger Begonia plants are in a state of growth arrest, going into dormancy or semi-dormancy.

In summer, we should cut off the dead flowers and leaves of Rieger Begonia and shade them in time. In addition, it is necessary to control watering to avoid standing water in the flowerpot and causing rotten roots. Fertilization should also stop.

Autumn and winter maintenance of Rieger Begonia

After summer comes autumn, when the temperature begins to drop and the plants begin to sprout new branches. When Rieger Begonia grows to a certain height, it can be pruned and the old branches cut off. When the new branches grow to a certain height, keep 3 branches, and the rest of the branches can be cut off, so that the nutrients can be more concentrated.

As October approaches, Rieger Begonia plants grow faster, keeping the soil moist and applying liquid fertilizer every half month is needed.

When entering winter, it is necessary to ensure that Rieger Begonia has sufficient light, and the temperature of maintenance should be kept above 10℃.

Key Points for Conservation of Rieger Begonia in Various Stages

When breeding Rieger Begonia, it should be noted that in the vegetative growth period of Rieger Begonia, the light needs to be kept at more than 14 hours, while the light time is less than 10 hours during flower bud differentiation, which is conducive to flower bud differentiation. When the plant is growing, it can be picked when it has 4 leaves.

Culture method of summer Rieger begonia

Rieger Begonia is a plant that likes shade. It grows very slowly in the high temperature of summer and is in a dormant or semi-dormant state. Summer is coming soon, how can we care for it? Let's learn about the summer management methods of Rieger Begonia. Friends who love it don't miss it.

Rieger Begonia likes wet, semi-cloudy environment, avoid strong light, in the sun exposure and dry air, stems and leaves easy to wither off, so summer should cover 50%-60% of the sun. Rieger begonia likes ventilated, cold environment, avoid high temperature, the optimum temperature for growth is between l5℃-20℃, so summer should be placed in a cool and ventilated place, otherwise the rhizome is easy to rot. Avoid ponding and big fat begonia for fleshy stems, summer should be properly controlled water and fertilizer, generally keep the pot soil moist, monthly application of thin fertilizer can be. Otherwise, too much fertilizer, easy to cause root rot. Avoid spraying water directly on leaves. Under high temperature, leaves cannot evaporate in time after being stained with water, which is easy to cause decay. Spray water near the basin and surrounding environment to maintain local air humidity and adjust temperature. The temperature suitable for the growth of Rieger Begonia is 15 ° C to 22 ° C, below 10 ° C the plant will stop growing, and more than 28 ° C will grow slowly. In order to reach the best growth state, the night temperature should be maintained at about 20℃, and the plants are easy to grow when the temperature exceeds 24℃.

Light: Rieger Begonia likes scattered light, avoid direct light, different growth stages of light requirements are different. At seedling stage, the light should be 15,000 lux, and then gradually increased to 25,000 lux. Producers can adjust light intensity according to flowering conditions.

Moisture: Water supply is important for the fleshy rootstock Rieger Begonia. Low water supply will affect plant growth; excessive supply will lead to rhizome disease, stem softening and other problems. Watering should adhere to the principle of seeing dry and wet, and do not wet the leaves when watering. Humidity: The early growth of Rieger Begonia requires higher humidity, and the relative humidity should be 80% to 85%; after the formation of buds, the relative humidity should be gradually reduced to maintain 50% to 60%. When the relative humidity is between 70% and 80%, attention should be paid to air circulation to avoid powdery mildew and gray mold. Pests and diseases: Domestic Rieger Begonia has fewer pests and diseases, but some fungicides should be sprayed regularly to prevent bacterial soft rot and powdery mildew. Agricultural streptomycin 200ug/g of 1000 times solution can be used for spraying. However, at home, ginger juice can be prepared with water and sprayed at a ratio of 1:25, which can prevent soft rot and germination of other pathogenic spores, which is very green and environmentally friendly. Rieger Begonia is a quantitative short-day plant. This means that plants do not necessarily require true short days to flower, but flower once a certain number of leaves are reached. But this flowering is irregular, and the number of flowers is small, the cultivation time will be longer and it will be more difficult to plan production. After summer, Rieger Begonia can be placed indoors or outdoors. It is an excellent garden and flower bed plant. It has a full bloom of 6 to 8 weeks. The Bacos strain is considered the most suitable for outdoor cultivation.
