What are the cuttage methods and precautions for Rieger Begonia
Do you want to know what the cuttage methods and precautions for Rieger Begonia are and your experience in green plant maintenance? Let's learn about it.
As an indoor potted plant with high ornamental value, Rieger Begonia is the most commonly used method for horticulture enthusiasts. Understanding the correct cuttage techniques and precautions can significantly improve the survival rate and cultivate healthy and beautiful plants.
##The best cuttage time is the best cuttage time. The cuttage time of Rieger Begonia has a significant impact on the survival rate. Spring and autumn are the best choices, with specific times from March to May and September to October. During this period, the temperature is stable between 18-25℃, which will not cause cuttings to lose water too quickly due to high temperature, nor will it affect root development due to low temperature. During the high temperature season in summer (especially from July to August), water evaporates quickly and easily causes the cuttings to wilting, while too low temperature in winter will delay rooting and even cause the cuttings to rot. If cutting must be carried out in non-ideal seasons, it is recommended to create a suitable environment in a greenhouse or indoor, and control temperature and humidity to improve the success rate.## The selection and treatment of cuttings directly affect the success or failure of Rieger Begonia cuttage. A mother plant that is strong and has no pests and diseases should be selected, and 8-12 cm long shoots should be cut from the top as cuttings. An ideal cutting should have 3-4 internodes, retain 2-3 healthy leaves at the top (large leaves can be cut in half to reduce transpiration), and the base cut should be 0.5 cm below the nodes, where meristem is active and easier to take root. Use a sharp disinfection blade (which can be wiped with alcohol) to make a 45-degree bevel cut to increase the water absorption area. The next step of treatment should be carried out immediately after cutting to avoid water loss caused by long-term exposure.## Cutting substrate preparation of Rieger Begonia cutting substrate requires good air permeability, water retention and drainage properties. Commonly used formulas include mixing perlite and vermiculite in a ratio of 1:1; or mixing peat soil, perlite and river sand in a ratio of 2:1:1. The substrate should be thoroughly disinfected before use. High-temperature steam disinfection or spraying carbendazim solution (diluted 500 times) can be used. Some cuttagers lay clean river sand 0.5-1 cm thick on the surface of the substrate, which not only maintains humidity but also prevents the base from rotting. It is particularly noteworthy that garden soil is easily hardened and carries a large amount of bacteria directly used as a cutting substrate, which is not suitable for plants such as Rieger Begonia that require high air permeability.## Tips for using rooting promoters Appropriate use of rooting agents can significantly shorten the rooting time of Rieger Begonia. It is recommended to use ABT rooting powder or indole butyric acid (IBA) solution, and the concentration should be controlled at 500-800ppm. Specific operation method: Soak 2-3 centimeters of the base of the cuttings in the rooting agent solution for 10-15 seconds, dry slightly before cutting. It should be noted that high concentrations of rooting agents may inhibit growth and should be prepared strictly in accordance with the instructions. For novices to cuttage for the first time, you can also try natural rooting methods, such as treating the cuttings with willow branch extract (water after soaking fresh willow branches for 24 hours), which also has a certain rooting effect.## Specific cuttage operation steps After completing the preliminary preparation, proceed with cuttage according to the standard steps: first use bamboo sticks to punch holes in the substrate to a depth of about 1/3-1/2 of the length of the cutting (usually 3-4 cm), and then place the processed cutting. Gently insert the cutting, and gently press the surrounding substrate with your fingers to make it in close contact. The cutting density is based on the principle that the leaves do not overlap, and the interval is generally 5-8 cm. Pour thoroughly with water immediately after insertion, and use a fine-hole spray can to avoid scouring the substrate. To increase humidity, cover it with a transparent plastic film (leave ventilation holes) or place it in a professional nursery box. Experienced growers will place a 1-2 cm drainage layer (ceramite or gravel) on the bottom of the basin to prevent stagnant water and root rot.## Key points for post-insertion maintenance management: Post-insertion management of Rieger Begonia should focus on the following aspects: Light control needs to avoid direct sunlight and provide bright scattered light (The light intensity is about 5,000 - 10,000 lux); it is ideal to keep the temperature at 20-25 ° C, and below 15 ° C will delay rooting; the humidity should be maintained between 70%-80%, which can be adjusted by spraying or humidifier, but the leaves should not accumulate water for a long time; Ventilation 1-2 times a day, 10-15 minutes each time to prevent the growth of mold. The ventilation time and light intensity can be gradually increased after about 7-10 days. Under normal circumstances, new root systems can be seen in 2-3 weeks, and can gradually adapt to the normal maintenance environment after 4-6 weeks.## Common problems and solutions Common problems during the cuttage process include: wilting of cuttings (indicating that water loses too quickly, and environmental humidity should be strengthened); blackening and rotted at the base (mostly because the substrate is too wet or carries bacteria, the substrate needs to be replaced and disinfected); Leaves yellowing and falling off (may be due to too strong light or malnutrition), etc. In response to these problems, management measures should be adjusted in a timely manner. Special reminder that sometimes cuttings have not taken root, but new buds appear at the top. This may be a "fake living" phenomenon (they will still die after nutrients are consumed). Do not remove protective measures too early. In order to improve the success rate, it is recommended to reserve 20% of spare cuttings for each cutting in case of emergency needs.## Timing and techniques for transplanting and placing in pots should not be transplanted immediately after the Rieger Begonia cuttings take root, but should be replanted when the new roots have grown to 2-3 cm and have multiple lateral roots (usually 4-6 weeks after transplanting). Properly control water 1 day before transplanting to make the substrate slightly dry, so that it is easy to remove the pot without damaging the roots. The new pot should be 3-5 cm larger than the root area, and use culture soil with similar properties to the cutting substrate. After transplanting, place it in a cool place to slow seedlings for 1 week, gradually increasing the light. Avoid applying fertilizer for the first 2-3 weeks, and apply thin liquid fertilizer (balanced nitrogen, phosphorus and potassium, diluted to 1/2 of the regular concentration) after the new leaves are unfolded. This work is best carried out during the spring and autumn seasons to avoid extreme weather. After mastering the various technical points of Rieger Begonia cuttage, regularly checking the plant status and adjusting the maintenance methods according to the growth conditions. Mature plants with beautiful shapes can be cultivated in about 3-4 months. Cutting propagation can not only retain the excellent characteristics of female parent, but also greatly reduce the cost of purchasing seedlings. It is an economic and effective method to expand the collection of Rieger Begonia.
