Four-season Begonia is a perennial herbaceous shrub from Brazil. It has a strong reproductive ability and can be propagated using branches or leaves, with soil or water as the growing medium. There are many varieties of Four-season Begonia, with double and single petals, flower colors including red, white, and pink, and leaf colors including green, copper purple, and dark brown. It is a common绿化 plant and many gardening enthusiasts cultivate it at home. Below, I will introduce the cutting method for Four-season Begonia.
Ⅰ. Cutting Time
Spring and autumn are generally suitable, and cuttings can also survive in winter. The optimal growth temperature for Four-season Begonia is between 15 and 24°C. In the southern regions, the warm and humid conditions in April and May are most suitable for cutting. Cuttings are more likely to root and survive at a temperature of around 20°C. If the temperature is too high, the cuttings are prone to rot, especially in the summer when the soil humidity is high, so it is not suitable to cut in the summer.
Ⅱ. Preparing Cuttings
Select a healthy two-year-old branch with two buds, with 3 or 4 internodes. Use a disinfected sharp knife to cut a 10 cm long branch from 1 cm below the last internode at an oblique angle as the cutting.
Remove the top tender bud of the cutting. If there are flower buds on the cutting, cut them off. Reduce the number of leaves, retaining only 3 or 4, and place them in a shady place for 2 days until the cut surface turns slightly white before cutting. Reduce the watering of the mother plant by 15 days in advance to slow down the growth, so that the cuttings are not too thin and fragile, making it easier for them to survive. Also, the leaves of Four-season Begonia can also be used for propagation by cutting.
Ⅲ. Growing Methods
1. Direct Soil Culture
Select soil with good drainage and aeration. Clean fine river sand or soft sandy soil can be used as the growing medium. The soil medium should be disinfected and sterilized. Do not use nutrient-rich soil or leaf mold for cuttings, as excessive fertilizer or too much organic matter can make it difficult for cuttings to root and prone to rot.
Select the number of cuttings based on the size of the pot. The pot diameter should be slightly larger than the size of one plant. If multiple cuttings are planted in a large pot, the spacing between plants should be 3 cm. Use a stick to make several holes in the soil, with a depth of one-third the length of the cutting.
When cutting, place the cutting in the hole and slightly press the soil around the base, then place it in a shaded environment with indirect light to recover.
Do not water immediately after cutting to allow the cut to heal. Water thoroughly 3 to 5 days later and then do not water again, keeping the soil slightly moist. After about 10 days, the plant can grow 3 to 4 cm of roots, at which point it can be moved to a location with direct sunlight, and after another 6 to 7 days, it can be transplanted into a pot.
If the seedlings are first grown in a cutting bed, they need to wait until the new roots of the cuttings have aged before transplanting them into a pot.
2. Water Culture First, Then Potting
Water culture has a high survival rate. You can first do water culture cutting and then transplant it into potting soil. Culture the cuttings in clear water in a glass bottle, submerge the cutting part in water, and place it in a semi-shaded and well-ventilated area. When 3 fibrous roots have grown at the bottom, after about 20 days, it can be transplanted into the pot for planting.
