Growing strawberries on ridges covered in weed matting is easy we've also grown them in grow bags on top of bales, both ways work very well. Cover them in either straw or fleece through the winter to stop them getting frosted. Its always at the end of the season you can take cuttings from the side shoots, just cut them of near the plant and set the new shoots in a pot compost. Cuttings can stay outside over winter, this will allow you to triple your strawberry plants year on year. In the summer moths you can harvest your beautiful tasty strawberries :-)
