Sweet William, belonging to the Dianthus genus in the Caryophyllaceae family, is a perennial herbaceous plant with dwarf stature and multiple branches. It comes in various colors such as deep red, purple-red, pink, yellow, and white, making it highly ornamental. Let's delve into the propagation time and methods of Sweet William.
1. Propagation Time
Sweet William is best propagated by cuttings in mid-March during the spring season when the temperature and humidity are suitable for its growth, increasing the chances of successful propagation. However, it can also be propagated at other times by controlling the temperature between 15°C and 20°C.
2. Selection of Cuttings
Both the terminal buds and axillary buds of Sweet William have the ability to root, with high survival rates. Select healthy terminal or axillary buds from vigorously growing and disease-resistant Sweet William plants. Use sterilized scissors to cut them, apply fungicide to the wounds, soak them in rooting water for 5-10 minutes, then remove and air dry them in a cool place.
3. Soil Preparation
Sweet William prefers loose and fertile soil with good air permeability and drainage, which increases the chances of successful propagation. River sand, washed with clean water and dried in the sun, can be used as the substrate for propagating Sweet William.
4. Propagation Method
Prepare suitable containers and fill them with plain sand. Insert the Sweet William cuttings into the soil, slightly burying the surrounding soil. Keep the soil moist by spraying water, and place the containers in a cool, shaded area. Maintain a temperature of around 15°C and spray water into the substrate 2-3 times a day. Rooting and survival usually occur within approximately 20 days.
5. Post-Propagation Care
After new leaves emerge, relocate the plants to a partially shaded area for care. Water regularly to keep the soil moist, avoiding waterlogging. Apply diluted liquid fertilizer every 15-20 days. Once the new leaves have grown 2-3 pairs, they can be transplanted. When the plants reach a height of around 20 centimeters, transfer them to large pots for further cultivation.
Sweet William prefers sunlight and mild climates, with an optimal growth temperature between 10°C and 25°C. It is sensitive to heat and cold, so proper care is essential.
