The main part of the vineyards of Lanzarote is situated in the valley of La Geria, which is significant for its covered by a thick layer of ash. Grape seedlings are planted in specially dug pits or trenches up to several meters wide. This is done first to make it easier to get to the roots to the topsoil, and secondly, to ensure the grapes with moisture. There are virtually no rainfall, irrigation is also not practical, the plants are fed with dew, which condenses on the walls of "funnels". Saturated soil with ash, in turn, tends to hold a long moisture.
