The runners produced by strawberry plants are an ideal way to propagate plates. Remove runners after the final harvest to avoid strawberry beds turning into a thicket of poorly fruiting plants.
To propage sink runners into a 3 1/2 inch (9cm) pot, ensuring teh roots are in contact with the growing medium. Don’t let the pots dry out. Once rooted sever the young plants from the parent. Plant out by the end of August for fruiting next year.
Perpetual strawberries produce few runners and it is best to buy new, certified disease-free plants every 2-3 years.
