How long does it take Osmunda japonica from planting to flowering?

Osmunda japonica takes 2-3 years to grow and blossom.

Lagerstroemia indica is usually sown in March-April, outdoors, and the seeds are evenly spread on the flat seedbed.

Sprinkle about 2-3 capsules every 3-4cm. After sowing, cover with fine soil about 2 cm thick. After about 10~ 14 days, most seeds germinated. Make sure the soil moisture after coming out. After the seedlings grow two pairs of true leaves, in order to ensure that the seedlings have enough growth space and nutrient area, we can choose to interplant the nursery after the rain, so that the air between the seedlings can circulate and the sunshine is sufficient. During the growing period, we should strengthen management, topdressing thin fertilizer 2-3 times in June-July, preventing drought in summer, watering frequently, and keeping the nursery moist, but remember not to overdo it. The height of seedlings can reach 50 ~ 70 cm in winter. Plants that grow well can bloom in the same year. After defoliation in winter, trim the side branches and open the flower branches in time. Transplanting in early spring of the following year.
