Flowering usually happens about 4 to 6 weeks after bud break, depending on weather. This can be a stressful time, as this stage will determine the amount of berries on each grape cluster, and the delicate grape flowers are vulnerable to damage from wind, rain, or even late frost.
Precautions can be taken – the use of giant fans to circulate the air, or sprinkling the vines with water to shield them in ice (yes, really!). Fortunately, frost is rarely an issue for us here in beautiful Dry Creek Valley.
On April 14th, we noticed the very first signs of flowering in the Zinfandel Vineyard this year. No, bees aren’t needed here, as the grape vines take care of the pollinating process on their own!
