A Vineyard Chronology


The following is a scenario of what takes place in a Maryland vineyard during a typical year.

JANUARY
Pruning begins in large vineyards. Hybrid varieties can be pruned earlier, vinifera varieties should be allowed to harden off as long as possible.

FEBRUARY
Pruning continues. Pre-emergent herbicides, if used, applied.

MARCH
Pruning completed. Cuttings collected and disposed of. Repairs to trellis made. New or replacement vines planted.

APRIL
Buds for current crop begin to push. Maintenance on vineyard equipment (tractor, mower, sprayer, etc) performed.

MAY
Bud-break. Spraying for fungus diseases initiated.

JUNE
Flowering begins. Shoots grow vigorously and are tied to trellis wires. Excess growth removed. Weeds sprayed or cultivated.

JULY
Growth continues at a rapid rate. Shoot thinning and hedging applied where necessary. Spraying with fungicides continues. Leaf pulling begun to prevent shading of grape clusters.

AUGUST
Grapes begin to take on color. Vine and grounds maintenance continue.

SEPTEMBER
Bird control measures activated. Early grape varieties harvested.

OCTOBER
Harvest continues. Post-harvest spray applied if needed.

NOVEMBER & DECEMBER
Vine leaves drop, wood hardens, vine lapses into dormancy and pruning of hybrid vines begun after hard frost.
