SELECTING A ROOTSTOCK FOR A WINEGRAPE VINEYARD

For over 130 years, rootstocks have been available to protect grapevines form soilborne pests. From the beginning, rootstocks have displayed varying influences on the composite grapevine created by grafting. These include influences on grapevine growth, fruit yield, and other viticulturally important vine attributes. During this time, researchers have chronicled many rootstock influences in field trials and controlled environments, and the published record of their findings is extensive (see selected works…

COMPARATIVE WINE GROWING CLIMATOLOGY

Climate is of paramount importance to winegrape growing. The seasonal pattern of sunlight, temperature, rainfall, and humidity influences both above ground and below ground vineyard environments. It sets the length of growing seasons and influences the likelihood of cold damage. Climate is the principle driver of seasonal vine growth and development, including fruit ripening and the development of sensory characteristics in grapes. Almost as important, climate affects the incidence, life…

WEATHER OUTLOOK and TOOLS

Long Range Outlook… Growers are probably wondering if this upcoming rainy season will be a benefit to the water picture for 2017. Present long range outlooks are calling for a weak La Nina to develop over the waters of the Equatorial Eastern Pacific this fall and remain in place at least through the winter months. These slightly cooler than normal conditions would be in sharp contrast to the moderate strength…

MAKING VINEYARD MANAGEMENT DECISIONS

At the most basic level, business management involves setting goals, planning, organizing, staffing, directing, and controlling.  Vineyard management, of course, is more complicated than this, especially given large amounts of borrowed capital, increasing regulations, rising investment per worker, intensifying needs for mechanization, the dynamics of the wine grape market, and the increasing sophistication of grape growing and expectations of grape buyers.  Also, unlike nonagricultural business endeavors, grape growers must positively…

Fruit Set Factors

Fruit set is the process in which flowers become fruit and potential fruit size is determined.  It occurs after pollen is released from male flower parts (anthers), lands on receptive female flower parts (stigmas), produces a tube that grows to the ovules, and fertilizes eggs contained in them.  Fertilized eggs form seeds, which induce surrounding (pericarp) tissues to grow and form a berry.  The size of the berry will be…

Rainfall, Frost, Weeds, Spring Diseases, Invasive Pests

ON THE NATURE OF VINEYARDS AND VINEYARD MANAGEMENT

  The wine grape industry, like all of agriculture, is under intensifying pressure from outside.  Increasingly, regulators, retailers, consumers, environmentalists, and others are weighing in on how we conduct our businesses.  While most are well intended, many are ignorant about the true nature, complexity, and requirements of our work and the risks involved.  At the same time, the demands of our work keep us so close to it and overwhelmed…
