Winter of 2010 Report Here in west central Illinois the low temperature dropped to minus - 12 F in mid January and remained there for several days. We have not observed any damage to either the buds or the wood. One good aspect of this sub zero cold period was that it occurred when it was supposed to, when the vines were their most dormant and it was preceded by a gradual cooling period with no unseasonably warm weather. Freeze and Frost Update 2007 Good News !!! In both our vineyards in central Missouri and Ilinois we experienced minimal damage on DVR vines due to the spring frost of 17 degree F. One reason for this was that the DVRs budded out later than all the other vines, including Norton. On neighboring vineyards there was extensive damage on Chardonel, Vidal and other French Hybrids and in many cases it looked as if the trunks will have to be renewed. On the DVRs the combination of late budding and excellent winter hardiness seems to have spared the vines, and the crop. The pictures below are of Crimson Cab as of May 8, 2007. |
