Backyard Grape Growing

Get started growing grapes at home with this Oregon State University Extension Publication. The guide will help you pick the right kind of grapes, how to prepare your yard, and inform you of the major pests that attack grapes.
Spotted Wing Drosophila is a new, invasive pest that attacks stone fruits and berries. Learn how you can keep the pest from spreading.

Canopy Management

Canopy management is critical for successful winegrape production. The canopy can be managed either directly or indirectly through vineyard practices.
Leaf area is a measure of canopy size and is one of the factors by which vine balance can be calculated. Like pruning weights, leaf area can be used to quantitatively describe areas of high or low vigor in your vineyard.
Since pruning is necessary every year to maintain vine structure, size, and yield potential it is easy to gather these data while conducting normal management practices.
Vine balance is a critical concept to understand in viticulture. Vineyard design and management methods used to obtain vine balance help sustain productive yields, achieve desired fruit quality, and preserve overall vine health. 
Protecting vines from low temperatures is of particular importance in colder regions. This guide describes the best methods for protecting vines from freezing tempartures.
eViticulture is the national online viticulture resource containing the latest science-based information for the commercial grape industry who need solid, tested, science-based information to improve their skills in the vineyard.
