What are the propagation methods for tuberous begonias?

Propagation methods for tuberous begonias: for growing tuberous begonias at home, use the cutting method. From June to July, cut off a healthy stem tip with a terminal bud, about 10 cm long, remove the lower leaves, let it dry slightly, then insert it into a large flowerpot filled with plain sand; spray with water from a watering can, then cover with a layer of plastic film to retain moisture;

Then place it in a cool spot with good indirect light; maintain a suitable temperature of around 20-25°C, open the plastic film once a day to let it ventilate and breathe, and mist it again; after 20 days it will heal and take root, and after one month it can be divided and potted up.

To encourage several stem tips to bloom at the same time, you can pinch off the most vigorous few shoot tips of the whole plant; once apical dominance is broken, more lateral shoots will sprout from below them; wait until the wounds have dried over before spraying water and applying a dilute liquid fertilizer.

Because it is a long-day flower, it should be given a longer period of indirect light each day, and the potted plant should be loosened regularly; water should be misted more and poured less, avoiding both overly dry and overly wet potting soil, while also spraying water around the plant to increase humidity and lower temperature; during the growing season, apply or spray a mixture of 0.2% monopotassium phosphate and 0.1% urea once every 10 days, which can help the leaves become greener, the number of flowers increase, and the flower colors become more vivid. That concludes the introduction to the propagation methods for tuberous begonias.

Light and temperature

Temperature and light: tuberous begonias like a warm and fairly humid growing environment, dislike the intense heat of summer, and cannot withstand the severe cold of winter; partial shade is best. The most suitable temperature for tuberous begonia growth is 16°C-21°C. If the temperature is above 30°C, the flower stems and branches and leaves are very likely to wither, and in worse cases the underground stem may even die. The minimum growing temperature should not be below 10°C, and care should be taken to keep it warm when overwintering. In addition, tuberous begonias also love light; good long-day sunlight is the basic guarantee for vivid blooming. In summer, ensure sufficient light while also making sure strong direct sunlight does not hit them. In winter, when sunlight is scarce, pay even more attention to providing enough sun.

Soil

The soil for planting tuberous begonias also needs attention: it should be nutrient-rich, loose, airy, and rich in humus; slightly acidic soil is also acceptable. Generally, we can add river sand to garden soil, or mix up leaf mold. In addition, adding some base fertilizer to the pot can increase fertility.

Watering

Tuberous begonias like a moist growing environment, but they are also afraid of waterlogging, so it is best not to let water accumulate. In summer, when the weather is dry, increase air humidity by misting and other methods; in autumn and winter, during the dormant period, reduce watering, and also reduce watering during the sprouting period and flowering period of tuberous begonias.

Fertilizing

Tuberous begonias relatively like water and fertilizer; when fertilizing, apply dilute fertilizer frequently. During the plant's growing period, apply some fully decomposed dilute fertilizer solution every ten days. During the flowering period, apply some fertilizer that promotes blooming. In winter and summer, be especially careful not to fertilize.
