How to propagate四季 crabapple (Begonia semperflorens)
Today, I will explain in detail how to propagate 四季 crabapple and the knowledge of the timing and methods of propagation, which is very useful. It's recommended to save this information for future reference!
Seasonal begonias are often planted in urban flower beds. They belong to the family Begoniaceae, genus Begonia, and are perennial evergreen herbs. The plants are low-growing, only 15-30 cm tall, with round leaves and bright green color. The flowers come in red, pink, white, and other colors. As a perennial evergreen herb with low-growing plants, they are suitable for flower beds or indoor potted plants. Seasonal begonias have a long blooming period, with small, bright, and beautiful flowers.
1. Propagation Time
Seasonal begonias can be propagated throughout the year, but ideally, it should be done in spring, around April to May. The mild climate of spring makes it easier for the cuttings to root, greatly increasing the survival rate.
2. Cutting Preparation
Select branches that are strong, have good germination ability, and have no buds as cuttings. Each cutting should be about 5 cm long, with two buds at the top, and the leaves should be cut in half to reduce transpiration.
3. Soil Preparation
Seasonal begonias grow well in loose and well-ventilated soil. A mixture of three parts peat soil and one part perlite can be used to prepare the propagation medium. Prepare a seedbed, plug tray, or seedling pot and place the soil accordingly.
4. Propagation Method
Make a diagonal cut at the bottom of the seasonal begonia cutting, dip it in rooting powder, and then insert it directly into the medium. Press the soil around it firmly and spray water. Maintain a temperature of 18-20°C, enhance ventilation, and the cuttings will root quickly.
5. Pruning in Seedling Stage
When seasonal begonias are in the seedling stage, it's common to pinch the tips to inhibit apical dominance, promote root growth, and make the plant fuller with more flowers.
6. Pruning after Transplanting
After transplanting seasonal begonias, observe the growth of the plants and consider pruning only after they have resumed growth. Avoid pruning too early. Mainly remove weak branches and leave 3-5 strong ones to allow nutrients to be concentrated.
7. Pruning during Growth Period
During the growing period, mainly prune weak, dense, diseased, frail, and yellowing branches to reduce nutrient consumption and increase light penetration in the plant.
8. Pruning after Flowering
After seasonal begonias bloom, it's appropriate to prune them by removing the残花 (spent flowers) and weak branches to prevent decay that could affect growth. After pruning, enhance care by applying a compound fertilizer twice a month to promote growth and flowering.
The above is a comprehensive explanation of how to propagate seasonal begonias and the timing and methods of propagation. I hope it helps you.
