Getting ready for harvest in orchards and vineyards…

By Terence Bradshaw Mid-August is approaching, and that means that fruit are beginning the ripening process in Vermont orchards and vineyards. This is an important time to plan some final management practices before things get too busy. Foliar (apple) and petiole (grape) tissue sampling: Now is the time to collect plant tissue samples for nutrient […]

Midsummer vineyard management

By Terence Bradshaw July 9, 2017 Now that the July 4 holiday is past us, it’s time to really think about getting quality into those grapes on the vines. That doesn’t mean that the work that has gone into the 2017 crop hasn’t yet affected quality: the pruning, shoot adjustment, pest management, and other activities […]

Disease management still critical in grapes

By Terence Bradshaw June 26, 2017 No one needs me to tell them that this has been a wet spring and now early summer. Most grapes are approaching, in, or maybe just exiting bloom across the state, and disease pressure continues to be possibly the highest of the season. Fungicide coverage should be maintained on […]

Wild grape bloom starts the clock for grape berry moth management

By Terence Bradshaw June 12, 2017 There is a wild grape that overhangs the South Burlington bike path just east of the UVM Hort Farm that I run by several days per week. Last Friday, June 9, it went into bloom (it was not blooming on my run the day before). Why is this important? […]

Grape tumid gall maker- curiosity and management

By Terence Bradshaw June 8, 2017 One of the great things about growing grapes in Vermont is that, by and large (and compared to my other crop, apples), the pest management is relatively simple- four or so well-timed fungicides sprays, and an insecticide aimed at grape berry moth. There are other considerations for unique situations: […]

Vineyard management approaching bloom

By Terence Bradshaw Grapes are at 10-12” growth in most Vermont vineyards, and combined with the wet, cool, rainy weather, are at prime susceptibility for phomopsis, black rot, and anthracnose. Fungicide coverage should be maintained on 7-10 day intervals during this extended rainy stretch; if it dries out as expected at the end of the […]

Vineyard management: Diseases and shoot thinning

By Terence Bradshaw 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. Growers should consider applying a protective fungicide soon that has activity against […]

Disease management in Vermont grapes- the season begins

By Terence Bradshaw Grapes are moving fast in Vermont vineyards, with most cultivars in the UVM vineyard at about 2” shoot growth. Shoot thinning now will give best results before the vines waste energy on growth that you won’t keep. We typically aim for 4-6 well-spaced shoots per foot of canopy, selecting for the most […]
