cycle of vine growth, how soils and climate affect grape growing, cultivars, rootstocks, clones, propagation,
training of vines, canopy management, mineral nutrition, soils and irrigation, pests and diseases, and methods to
improve winegrape quality.

Course Objectives:        Upon successful completion of the course, the student will be able to describe the
grapevine’s yearly cycle of growth, list winegrape varieties, rootstocks; describe trellis types, pruning, training
and canopy management techniques that are appropriate. The student will be able to identify common vineyard
problems and suggest remedies. The student will be able to describe the entire process of grape growing from
site feasibility determination, to planting and training a vineyard, to improvement of quality and harvesting fruit
for a Sonoma County vineyard.
