Evaluating Vine Stress in the Vineyard

“Every week we measure shoot lengths because you want to know how rapidly the grape vines are growing. You want to know when the growth starts to slow down. And you want to know when they come under water stress to make the decision on when to start irrigating. If you feel the sun leaves […]
