Sample Collection & Preparation for Perennial Fruit Crops

Managing excessive vine vigor is one the greatest battles in Eastern viticulture and this problem is exacerbated in seasons with high rainfall and warm spring temperatures. Many vigorous varieties and variety/rootstock combinations are quickly beginning to increase in shoot length.

The annual goal in the established vineyard is to have the vines fill their allotted trellis space, top out vegetative growth just above the top wire at veraison, and produce a crop that is in balance with the vegetative vigor.

Spring frost is a significant production hazard in nearly all locations in the MidAtlantic however (luckily!) most areas of Maryland do no experience damage frequently compared to other areas. As with most issues in viticulture, prevention or avoidance through excellent attention to site selection is the best option to reduce risk. With that said, the following is some information on what to do when an event has occurred.
