The last few days have been very cold across Spain and many landscapes and vineyards, including Viña Lanciano, have been blanketed with snow. Contrary to what many people think, heavy snowfall actually has a positive affect on vine growth and health.
During the winter, the vines are in a period of vegetative dormancy. A situation that insects and fungi can take advantage of by infecting the bark of the vine and damaging the plant. But the snow gets rid of them, freeing the plant from unwelcome guests, closing up wounds and allowing it to reach spring in a healthy condition.
The snow and the cold make it possible for any pruning cuts made to the plant to heal quickly. And without this healing, the vineyards could pick up diseases that could pose a threat.
Precipitation in form of snow entails considerable water reserves, as when the flakes fall gradually, they soak the ground and provide nutrients.
Although, of course, it’s not all good, after heavy snowfall, the plant could be exposed to extreme frost over a series of nights. Although in this regard, the geographic location of Viña Lanciano – elevated over a meander in the River Ebro – serves as natural insulation against these frosts.
As we know, popular sayings always contain a grain of truth and this is also the case with the proverb: “A year of snow, a year of plenty”.
