How to propagate strawberries with ramets?

Propagation of mother plants by ramets is also called rhizome propagation or split-pier propagation. This method, first, is used in the old strawberry orchard that needs to be updated and replanted, and all the plants are dug out and sorted well; Second, it is used for some strawberry varieties that are not easy to crawl.

When the mother plant is used for propagation, it should be carried out after the fruit is harvested in the production garden. Before dividing plants, we should first strengthen the management of mother plants in the dividing plots, and timely carry out fertilization, irrigation, weeding, loosening soil and other work to promote the axillary buds of new stems to send out new branches. In July and August, when some new leaves are extracted from the aboveground part of the mother plant and new roots grow from the underground root system, the old plant is dug out, the black adventitious roots and aged rhizomes at the lower part are cut off, and the upper rhizomes of 1 ~ 2 years are selected to be separated one by one. Generally, these rhizomes have 5-6 stout leaves and 4-5 vigorous adventitious roots, and the length is less than 4 cm. The separated rhizome can be directly planted in the production garden. Water in time after planting, strengthen management and promote growth. In the second year, they can bear high-yield normal fruits. For rootstock seedlings with only leaves and no fibrous roots, 1 ~ 2 leaves can be kept, and the rest leaves are all cut off, then shaded cutting seedlings can be carried out to make them grow new roots, which can be planted in autumn after the new leaves grow, and fully nutritious seedlings can be cultivated before overwintering.

The propagation coefficient of ramet method is low. Generally, each three-year-old mother plant can only separate 8 ~ 14 vegetative seedlings suitable for planting standards. In addition, most new stem seedlings separated from wounds are susceptible to soil-borne pathogens. However, the ramet propagation method does not need a special propagation site, and it can save labor and reduce costs by removing redundant stolons and pressing soil on stolon nodes.
