Grape canopy management

By Terence Bradshaw High Summer is here, and this period from after July 4 through early August is the perfect time to apply some canopy management to the vineyard. By thinning and positioning shoots; removing unwanted clusters; and cleaning up trunks, we can significantly increase penetration of sunlight into the canopy and especially into the […]

Vineyard management at bloom

By Terence Bradshaw Many vineyards are in bloom across Vermont, and inflorescence looks good and bodes well for a promising year. As I’ve been saying all along, be sure to maintain spray coverage for the next couple of weeks; to remove any diseased tissue as you find it; and to do your best to maintain […]

July 9 UVM Grape Canopy Management Workshop

By Terence Bradshaw Summer canopy management is one of the most important tasks for producing high-quality winegrapes, especially in cool/cold regions where ripening can be impacted by low heat unit accumulation. The tasks taken to open and manage canopies aren’t necessarily intuitive, and are often overlooked by beginning fruit growers. Join the UVM Fruit Program […]

Grape pest management, June 19

By Terence Bradshaw June 19, 2019 It’s always impressive to me how fast grapevines can go from zero to full foliage in a matter of a couple of weeks. Vines at the UVM Horticulture Research & Education Center are generally at 16-24” shoot growth. We’re not quite at “Immediate Pre-Bloom” stage, but not far off, […]

Grape disease management and shoot thinning

By Terence Bradshaw I’m probably a tad late on getting this out for some growers. The growing season continues to be cool and wet, and grapevines at the UVM Horticulture Research & Education Center are showing about four to five inches of shoot growth. We are beginning to enter a critical time for disease management. […]

Early vineyard management

By Terence Bradshaw Buds have broken in most Vermont vineyards and many vines are at 1-3” shoot growth. This brings up a few pest management considerations for your vineyards. Most cold-climate cultivars will not need disease protection until 5-8” of shoot growth, but any vineyards with heavy disease pressure last year may wish to begin […]

Grape flea beetle, weed management

By Terence Bradshaw May 5, 2019 Buds are swelling in Vermont orchards. I haven’t looked at our vines in South Burlington since Friday, and they were fully swelled then, but I cleaned up my vines at home (1500’ elevation, Washington county) today and they were quite swelled up. I expect bud break any day now. […]

Beginning the 2019 viticulture season

By Terence Bradshaw After a long winter, spring is here and bud break is approaching. Plan on wrapping up pruning in the coming weeks and removing brush from the rive alleys to the burn pile (and burn it, too, to reduce overwintering insects and disease inoculum). This is a good time to review your previous […]

2019 New England Wine and Grape Growers Survey

By Terence Bradshaw I am working with an Lizzy Holiman, an undergraduate UVM student who is studying viticulture and wine making practices in relation to climate change adaptation in New England. If you have a couple of minutes to complete this survey that will guide her research question, we would really appreciate it. Please feel […]

VBFG Pruning workshops

By Terence Bradshaw This winter, the UVM Fruit Program will hold a number of apple and grape pruning workshops around the state as part of the Vermont Beginning Fruit Grower (VBFG) project. Each workshop will be limited to twelve people so that we may provide time and attention to each participant. The first workshop will […]
