If you live in a mild climate, then set your strawberry containers on a south-facing porch or patio.
Make sure you choose a strawberry pot that is light in color to reflect some of the sunlight.
In terms of soil, fill the pots with loamy potting soil that will hold moisture without getting boggy.
Starting strawberries from seed is a long, difficult process and not recommended unless you are a very patient person.
Water frequently enough through the spring to keep the soil moist without overdoing it.
If you are growing strawberries as ornamental plants, then by all means let the runners drape over the sides of the container.
