When to Plant Grape Vines in Michigan?

Michigan's climate and fertile, well-drained soils warrant the inclusion of grapes in a productive home fruit garden. Choose a wind-protected site that receives at least eight hours of direct sunshine daily for the healthiest plant growth and fruiting.
  1. Time Frame

    • Plant grape vines as early as possible in spring when the soil is workable, according to horticulturist Thomas Zabadal of the Michigan State University Extension website. Plants ideally are still dormant with no leaf buds swelling or already open, revealing leaves.

    Geography

    • Michigan endures cold winters, so choose grape vine varieties known to be winter hardy in your part of the state. Generally speaking, a dormant grape needs to survive temperatures -5 to -15 degrees F to be reliable and worthwhile to grow in Michigan. Upper Michigan is in U.S. Department of Agriculture Hardiness Zones 3, 4 and 5, while Lower Michigan in Zones 4, 5 and 6.

    Expert Insight

    • Zabadal mentions that roots of grapes need to be spread out evenly and widely in the planting hole. Do not cram roots into tiny holes or in soil that isn't amended and tilled with organic matter. Once planted, water to keep roots moist but never waterlogged, and keep weeds at bay with mulch or regular hand weeding.
