The large yellow flowers of the narcissus, resembling trumpets, are among the first spring flowers. The bulbs to bloom in spring should be planted during the autumn. From the beginning of September to December is the right time for sowing spring bulbs, but the earlier the better. We plant the bulbs, in such a way that their tops are two centimeters below the rim of the pot, and then we fill the pot with soil. Then we store the pots in a dark and cool place, for six to eight weeks. When the roots begin to come out and the shoots grow, place the pots on a cool window. Bright lighting is necessary for their proper development. The temperature should not exceed 15 degrees Celsius.
