Propagate new strawberry plants from transplanted nursery berry plants by moving the strawberry's runners to open spaces in the bed. Typical plantings space plants 18 to 30 in. apart in rows 3 to 4 ft. apart.
There are four main types of plant propagation depending on the type of plant. Propagation methods include taking cuttings, dividing roots, sowing seeds and air layering. Which type of plant propagation method you use will depend on the type of plant you are trying to increase. Some plants can be propagated fairly easily in more than one way, eg strawberries which can be grown from seed also produce plantlets at the end of runners after the fruiting period.
