Pot up the strawberry bareroots into individual pots so that the crown of the plant is just poking above the surface. Avoid planting them too deeply as this may cause them to rot. The compost should be kept moist but care should be taken not to let them get too wet as this will also rot them.
Strawberries are perfectly hardy so the pots can be stood outside in a sunny spot of the garden as a temporary measure until they are ready to be planted. Alternatively, if there is plenty of space, put them in the greenhouse and let them root into their pots over winter, before planting them out in spring when they have developed a good root system. Either way, they will need potting up until they are ready to be planted.
