HOW SHOULD I CARE FOR MAY GRAPEVINES?

Vines are normally planted bare root from January to March and spaced 7 to 8 feet apart in rows 10 to 12 feet apart. Vertical stakes or posts with 1 or 2 wires on the side, or with “T” tops with wire are desirable supports for grapevines. Cane prune Thompson seedless and Concord. Spur prune other varieties. Frost (31oF) damages new shoots and fruit clusters in April or May, so plant where the frost is minimized. Spraying or dusting sulfur for mildew is necessary on wine and table grapes, but rarely needed with American types. (From http://ucce.ucdavis.edu/files/filelibrary/40/935.pdf )
