The Propagation of Rieger Begonia
Do you know about this? Here is some knowledge about the propagation of Rieger Begonia, specifically the methods of propagating Rieger Begonia:
The main methods of propagating Rieger Begonia are sowing and cutting, with a more professional method being tissue culture. However, for most amateur gardeners, the cutting propagation of Rieger Begonia is the most convenient and reliable, so this article will focus on the cutting propagation of Rieger Begonia.
In the late autumn and early winter, when pruning and shaping the plants, the newly cut branches can be used as cuttings. Rieger Begonia can be propagated by both stem and leaf cuttings. When using stem cuttings, the length of the branches should be moderate, and the lower part of the branch should be cut into a horseshoe shape with a blade; when using leaf cuttings, select vigorous leaves that are six parts mature, and cut the lower end of the petiole diagonally with a blade. The cutting medium should be either vermiculite or clean sand, and any contaminated medium should be sterilized before use. After inserting the cuttings, water thoroughly, but do not let water accumulate on the leaf surface. Cover them with plastic film, place them in a scattered light area, provide proper ventilation, and avoid high temperatures. In about 3 weeks, the cuttings will root. When new leaves appear, it indicates that they have rooted. Plants obtained by stem cuttings do not have underground tubers. After 3 weeks, the lower part of the petiole can also grow fine roots, but it will take another 1.5 months for adventitious buds to grow from the lower part of the petiole and gradually emerge from the soil.
Gardener's Case (Smoking Ear):
Method of Rieger Begonia cultivation: (Personal opinion, for reference only. Welcome to correct me!) Gardener's experience
1. Water sparingly but thoroughly, especially during the high-temperature dormant period in summer.
2.散射光照 is sufficient, direct sunlight in winter is okay, but not too strong, otherwise, the stems and leaves will turn red.
3. Place in a well-ventilated area, this is very important.
4. Try not to water the leaves.
5. Do not use organic fertilizers, except urea, as they can easily cause bacterial infections. Apply granular compound fertilizers to the soil surface without touching the rootstock, as contact will cause rotting.
6. Fertilize sparingly, using half the usual concentration.
7. Choose a well-draining soil for planting. (I use high-quality soil, which may sound like advertising!)
8. Disinfect the blade when pruning branches and leaves! (Very important)
9. To prevent root diseases, pour a 1:1000 potassium permanganate solution on the roots once every 1-2 months. Do not do it too frequently.
10. The suitable soil pH value for the growth of Rieger Begonia is between 5 and 6. Pour a mixture of 1:5:1000 sulfuric acid iron, white vinegar (without NaCl), and water on the roots twice a month. If the soil pH value is too high, the begonia will have various problems.
In summary, when cultivating Rieger Begonia, always pay attention to rotting and bacterial infections. Whether it grows well or not depends on water, pH value, fertilizer, soil, and light.
