Vineyard

What looks like an unpromising site for a vineyard in Valle do la Geria in Lanzarote in the Canary Islands. The farmers dig holes in the volcanic soil and fill them with volcanic ash. A smaller hole is dug in the centre of the pit for the roots of a vine. The vine relies on the moisture retained by the porous ash from night time humidity and morning dews. Crescent shaped stone walls called zocos are built to shelter the plant from the northern prevailing winds.
