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.
Lesson Summary. Plants can propagate using either sexual reproduction or asexual reproduction. The various types of vegetative propagation are examples of asexual reproduction. The offspring of the plants are clones of the original plant since no mixing of DNA occurs. The most common forms of vegetative propagation are grafting, cutting, layering, tuber, bulb or stolon formation, suckering and tissue culture.
