Growing tips:
Oriental knotweed requires a period of cold weather to germinate successfully. The germination process is slow but continuous and typically takes 21 to 60 days, depending on the prevailing temperatures. Indoor sowing is best done in a seed tray. Initially, a period of 2-4 weeks at a temperature of 18-22°C is recommended, followed by 4-6 weeks of cold weather, for example, in a refrigerator at around +4°C. Afterward, the seeds are gently warmed back to room temperature, which is particularly beneficial for the germination process.

Alternatively, sowing can be done in the garden in late summer or fall, with the plants simply left over winter. Germination then occurs in spring. Early sprouting often results in shorter, but more vigorously branched plants. It's important to pay attention to this specific germination process to ensure optimal conditions for growth.
