The rose bushes that you see at the end of vineyard rows are not just for good looks. Giulian at Enoteca di Piazza in Montalcino explained to me that roses, being the sensitive plants they are, actually help gauge overall vineyard health. Roses can reflect potential damage of over- or under-watering, fertilizer applications or weather damage. Carefully observing the rose bushes can help winemakers make important decisions regarding changes that may need to be made in the vineyard or in the specific row. The roses are like a vineyard signal, showing damage first. And give the winemaker a little time to alter treatments or irrigation schedules. If the roses are thriving, the vineyard is thriving, too.
