After sowing, cover with a fine layer of sieved compost or vermiculite, then move them to a heated propagator or pop them on a warm, sunny windowsill at 10 to 15 degrees C. And a couple of weeks later, the seedlings will appear.
播种后,覆盖一层细筛的堆肥或蛭石,然后

移至加热的育苗器中,或者放置在温度为10至15摄氏度的温暖阳光
的窗台上。几周之后,幼苗就会萌发。 当然,为了保持湿度和水分, 用塑料袋覆盖花盆也是一个好主意。
