The daughter plants become mother plants and soon send out their own daughter plants, and so on and so on. Because of their tendency to spread, gardeners have developed several systems for growing and containing strawberries. The matted-row system is one popular way to grow strawberries. Plants are spaced 18 inches apart in rows four feet apart. The hill system is another popular way to grow strawberries.
Space plants one foot apart in rows with two or three feet between the rows.
You can just plant whatever and however you want, and you'll always get strawberries. After three or four years, your mother plants' production will begin to decline, and at that point it's best to dig them up and start all over again. In the meantime, make sure to give your strawberry plants all the attention they need, including vigilant weed control, regular watering, monthly applications of balanced fertilizer, and protection from freezing and thawing cycles during the winter with mulch. Straw is the best mulching material for strawberries.
