If the seeds harvested in spring are sown in autumn, the germination rate will be halved. Therefore, the harvested seeds should be dried and refrigerated to reduce their metabolic activity and prolong their life. Sowing time should be determined according to the required flowering time, winter flowering can sow in late spring, spring flowering can sow in early autumn. Sowing seedlings in late spring will soon enter the hot summer, it is necessary to do a good job in cooling, otherwise the seedlings are very easy to die in the extremely hot weather. A small amount of planting can be sowed in April, and when summer comes, the seedlings have grown up and have strong heat resistance, so they can spend the summer safely in a shady and ventilated place.
