Growing flowers from seeds is the most economical way to add beauty to your landscape and garden. Not only are seeds inexpensive, but you can store them easily and plant them when you have the time, rather than trying to keep a seedling or young plant alive until you are ready to plant it. In addition, watching a flower grow from a small seed is a rewarding experience and a great educational lesson on plant life for children.
Choose the right seeds. If you are a beginning gardener, or you want to sow your seeds directly into the soil outdoors rather than starting them in pots indoors, choose flowers that have large, easily-germinating seeds such as sunflowers, marigolds, cosmos and nasturtiums.
Prepare the planting bed. Be sure to choose a location that gets the amount of sun your flowers will need. Wait until all danger of frost is past and the ground has thawed. Remove large rocks and plant debris from the soil.
Work organic mulch into the soil to a depth of 8 inches with a shovel. Rake the soil smooth, then water thoroughly and let the soil settle for a day.
Dig a shallow trench with a trowel and press the seeds gently into the soil. Some seeds may be planted so shallowly that you do not need to dig a trench at all. Be sure to read the seed packet to find out how far apart the seeds should be spaced and how deeply they should be planted. Cover with a layer of fine soil.
Water slowly with a fine mist so that the seeds are not washed away. Keep the soil moist until the seeds germinate and the flowers sprout. After that, water as directed by the instructions on the seed packet.
