Throw the Blossombs wherever you want flowers to grow! Blossombs do not have to be buried, but you can press lightly into the earth if necessary. Then simply just wait for the rain or sprinkle with a watering can. Soon they should 'burst' open, and you will see small plants appear. The best sowing time is March to September. If planted after this time, the bulbs should blossom the following spring.
