Fruits, Nuts & Perennial Crop CalendarsVineyard Calendar: Year-Round Tasks
A vineyard runs on the vine's growth stages, and each stage has its own work. This calendar follows the grapevine through the year so you can match tasks to what the vines are doing.
Key points
- Tie each task to a vine stage and your local frost dates.
- Bud break is the main frost risk period.
- Canopy management supports both fruit quality and disease control.
- Keep records of stage dates, weather and harvest numbers.
What are the main stages of the grapevine year?
The annual cycle runs from dormancy through bud break, shoot growth, bloom, fruit set, veraison and ripening, then leaf fall. The eXtension grape annual cycle page and several state publications describe each stage in order.
Vines respond to temperature, so the dates shift by region, variety and year. Anchor each task to a stage and your local frost dates, not to a fixed date.
Write down the date of each stage every year. After a few seasons you will know your own site's pattern, which is more reliable than any general schedule. For example, if bud break on your site tends to come when the last frost has only just passed, your frost watch should begin well before the first green shows.
What do you do during winter dormancy?
Dormant pruning is the major task. You decide how many buds to leave, based on vine size and your variety and training system, with guidance from your extension service. Prune after the worst cold has passed in cold regions, since buds can be damaged by hard winter freezes.
Winter is also the time to repair trellis posts and wires, service equipment, review last year's records and take soil or tissue samples as advised locally.
Order new vines and supplies now, so they arrive before spring planting.
- Prune after severe cold passes
- Repair trellis and irrigation
- Review records and plan the season
What happens at bud break and early shoot growth?
Bud break is the moment the vineyard is most exposed to late spring frost. Watch the forecast, know your site's cold spots and use frost protection methods only as local rules and your extension advice allow.
Shoot thinning, tying and early canopy management start now. Remove shoots in the wrong place and position the rest on the trellis.
Disease management begins early in many regions because the fungi that cause common vine diseases start with wet spring weather. Ask extension for current local guidance.
What is the work during bloom and fruit set?
Bloom is a sensitive period for weather and for disease. Rain and cool temperatures can reduce fruit set, and some diseases are of special concern at this time.
Canopy management continues. Leaf removal, shoot positioning and hedging help air flow and light reach the fruit zone, which affects both disease and fruit quality.
If you use any pesticide, read the label, follow pre-harvest intervals and protect pollinators. Applicator licensing rules vary by state, and restricted products may require a license.
What happens during veraison and ripening?
Veraison is when berries begin to change color and soften. After that, sugars rise and acids fall. Many growers start sampling berries to track ripeness and to plan harvest.
Bird and wildlife pressure can rise at this time, and netting or other exclusion is an option for some growers. Check local rules on wildlife control.
Keep irrigation matched to the vine and your soil, using local guidance, since too much water late can dilute fruit quality while too little can stress vines. Keep a few vines marked for sampling so you compare the same vines each week, and note weather alongside the numbers.
How do you decide when to harvest?
Harvest timing depends on the grape type and your goals. Growers use sugar, acidity, pH, taste and seed and skin maturity, and wineries and extension offices often provide testing help.
Pick dry if you can, handle fruit gently and move it to cooling or processing quickly. Plan crew, bins and transport before the first pick.
After harvest, keep records of yield, quality and weather. They are the basis of your next year's decisions. Wine grapes, table grapes and juice grapes each have different targets, so ask the buyer or your extension specialist what they want before you plan the pick.
What post-harvest work protects next year's crop?
After harvest, vines still need leaves to store energy. Keep canopy healthy for as long as weather allows and manage disease that could reduce reserves.
Fall is a good time for soil sampling, for planning any amendments from a soil test and for repairing equipment. Nutrient management rules vary by state, so check local requirements.
In cold regions, winter protection for tender varieties, such as hilling up or covering, depends on your extension guidance and your variety's hardiness. Write down what you learn each season, since your own records are the best guide to your site. Review them with your extension office before the next season.
