Dormancy
November-MarchCanes are woody and leafless; vines rest after harvest through late winter
Prune during dormancy to remove old wood and shape the vine. Apply dormant oil spray in late winter to control overwintering pests.
Budbreak & Shoot Growth
March-MayBuds swell and shoot forth new green growth with emerging leaves
Apply pre-bloom fungicide sprays. Install trellising or support structure. Begin training shoots to canes. Ensure adequate water.
Flowering & Fruit Set
May-JuneTiny flowers appear in clusters; after pollination, small green berries form
Avoid over-fertilizing with nitrogen. Thin fruit clusters by removing damaged or small berries to increase remaining grape size. Maintain consistent watering.
Fruit Development & Veraison
June-AugustGrapes enlarge and change color from green to deep red; sugar content builds
Reduce watering slightly to concentrate sugars. Remove excess leaves to expose fruit to sunlight without sunburning. Monitor for pests and disease.
Harvest Readiness
August-SeptemberBerries reach full size and deep red color with maximum sugar and flavor
Test sugar content with a refractometer (aim for 15-17 Brix). Harvest clusters carefully. Store at 32-35°F with high humidity for extended shelf life.
