How to Grow Flowers from Seed

1. 
   1
   Choose a container. There are a variety of inexpensive options available. Germinating flats are cheap and specifically created for the purpose of germinating seeds. Plastic drinking cups and recycled egg cartons are other inexpensive options, however. Small flower pots will also work.

   Make sure your container provides enough room for your seeds to develop.The best containers are 4 or more inches deep. This allows the flower's root system to develop.

   Sterilize the container. If using an old plastic pot or tray, soak it in a solution containing one part bleach and nine parts water, and rinse thoroughly. If using a new container, sterilization may not be necessary.

   Provide adequate drainage. Most plastic pots and germination trays already have holes in the bottom for water to drain out. If using a plastic cup, egg carton, or another container without any holes, punch a small hole in the bottom of the container before filling it with soil.
