The flowering method of a string of red seasons

1. Sowing by stages: the florescence of a string of saffron varies with the time of sowing. Generally, most of the seeds are sown in the open field from April to May, and the natural flowering period is from September to October. It takes 6 to 8 months from sowing to flowering. It varies slightly with the time of season and varieties, and the sowing time can be counted back according to the flowering time.

2. Cutting propagation: the use of cutting propagation to shorten the seedling stage can make the flowering period 2-3 months ahead of time. According to the time of flowering, cuttings can be cut at the right time. First, twigs about 10 cm long are cut and inserted into substrates such as plain sandy soil or perlite. The cutting depth is 2-3 cm, and water should be sprayed after cutting. Then keep the room temperature at 20-25 degrees. After about 25 days, it can take root. After 40 days, it can be planted in a flowerpot with a diameter of 15 cm, and some quick-acting fertilizer can be applied properly after slow seedling, while keeping the soil moist, and it will blossom after 2 months.

3. Pick the heart many times: generally, when the seedling grows to 5 leaves, leave 2 leaves to pick the heart, and when the lateral branch grows another 5 leaves, you can pick the heart again. This can be carried out repeatedly, on the one hand, the plant can be greatly dwarfed, on the other hand, the flowering date can be relatively delayed, in addition, all the buds of the whole plant can be removed at one time, and the sequel can still bloom. In this way, the flowering time can be relatively delayed by about 1 month.
