Annual flowers are flower species that grow and reproduce each spring and summer, but then die in the winter. Normally, these flowers require repurchasing and replanting each year. This can become expensive and burdensome for a home gardener. However, with a little time and plenty of patience you can regrow your annuals year after year.
Watch your annuals for whenever the flowers begin to wilt and die.
Remove the seeds from the dead flowers.
Place the seeds into seed envelopes and store them in a cool place until the next planting season.
Review a garden seed packet to determine the recommended indoor germination period and best season for outdoor planting.
Plant your collected seeds indoors in small flower pots using a standard potting soil blend. Do not use soil from your yard, as it will contain bug eggs that may hatch in your warm home.
Place the seeds in a warm, safe place and keep the soil moist until the plants emerge.
Place the emerged plants near a sunny window and continue watering whenever the top 1/2 inch of the soil is dry.
Move the pots outdoors for progressively longer periods to begin acclimating the plants. Place them in the area you intend to transplant them so that the plants adjust to the natural conditions. When the plants are outside for the entire day, transplant them into their outdoor placements and continue care with consistent watering.
