How to grow dahlia from seed

Those looking to learn how to grow dahlia from seed will find the process remarkably simple. Growing from seed allows you to produce a wide variety of flowers in a large array of colors. Not to mention the overall pleasant feeling of accomplishment that growing a flower from seed gives you.

Germinating Dahlia Seeds

Begin by preparing the soil. Soil for seeding can be purchased from any home or garden store. Spread the soil mix evenly in a low potting tray. Sprinkle the seed mix evenly over the top of the soil and then lightly cover the seeds with more potting soil. At this point, you should dampen the soil, but it is important not to overwater. Place in a well-lit area or under grow lights. Continue to water the soil lightly for 7-10 days. By this time, the seeds should have sprouted.

Transplant into Plugs

Once the sprouts have reached a height of three inches or more it is time to transplant them into plugs. Plugs are small cells that are designed to hold one plant. Fill these plugs with a two parts potting soil to one part sand mixture. Continue to lightly water on a daily basis for five weeks.

Transplanting Dahlias

At five weeks, your dahlias are ready to be transplanted to the garden or flower bed. Begin this process by hardening the plants off for 7-10 days. This is accomplished by taking the dahlias outside during the day but bringing them inside at night. This will prevent the plants from going into shock when they are permanently moved into the garden. Choose a sunny area of the garden and plant your seedlings. Do not be afraid to plant them deeply. The deeper they are the stronger their roots will be. Water twice a week until their root system is established.
