in established vineyards where only a few vines need to be replaced within a row (such as vine lost to machine damage or disease), a new vine can be propagated by bending a cane from a neighboring vine into the ground and covering it with dirt. this segment of vine will soon begin sprouting its own independent root system while still being nourished by the connecting vine. eventually, the connection between the two vines is severed, allowing each vine to grow independently.
