In the Vineyard
Consistent winter hardiness over many years, although injured at Zone 4a and 3b sites during the 2014 Polar Vortex winter and again after the -38F cold event in January, 2019. A good choice for Zone 4b sites and on good sites in Zone 4a. Good early winter hardiness. Was not injured by the November, 2014 sub-zero (-12F) cold snap, nor the mid-December 2016 cold event (-22F on 17 Dec. in Hugo, MN). Excellent late winter hardiness. No injury after the February, 2021 cold spell that culminated with a low of -32F on 15 February in Hugo, MN. Also, holds dormancy well during late winter warm spells, such as the record warm spell + freeze in March, 2012 that caused trunk injury to many varieties. Late budbreak in spring allows it to escape late spring freezes; very fruitful secondary buds. Widely adaptable to different soil types and alkalinity, from 6.0-8.0. Moderate drooping growth habit with few laterals. Low maintenance. Disease Resistance Petite Pearl is quite resistant to Downy and Powdery Mildew. Some susceptibility to Black Rot in more humid regions like the Northeast, Mid-Atlantic and parts of the Midwest. A nominal well-timed spray program (two pre- and two post-bloom sprays), provides good Black Rot control on Petite Pearl. Petite Pearl has, occasionally, shown symptoms of Phomopsis under very wet conditions. It is preventable with well-timed pre-bloom sprays. |
