Dormancy & Bud Break
December-AprilVine appears leafless and dormant in winter. In spring, buds swell and break, revealing tender shoots and small leaves.
Prune in late winter while dormant. Remove dead or diseased canes. Apply dormant oil spray if needed. Avoid pruning after sap flow begins to prevent 'bleeding.'
Vegetative Growth
April-JuneShoots elongate rapidly, leaves expand, tendrils develop. Vine grows vigorously with new canes reaching their full length.
Provide sturdy trellis or stake support. Train main shoots along support structure. Remove excessive shoots to maintain shape. Water consistently. Apply balanced fertilizer monthly.
Flowering & Fruit Set
June-JulySmall, inconspicuous greenish flowers appear in clusters. After pollination, tiny hard fruits begin to form and slowly enlarge.
Maintain consistent watering; irregular watering causes fruit drop. Avoid excessive nitrogen, which promotes leaves over fruit. Thin excessive fruit clusters if desired for larger berries. Ensure good air circulation.
Fruit Development & Ripening
July-SeptemberFruits grow steadily, gradually changing color from green to deep purple-black. Grapes become sweeter as they ripen.
Reduce nitrogen fertilization. Water deeply but less frequently. Remove some leaves shading fruit clusters to increase sun exposure and sugar accumulation. Monitor for pests and diseases.
Harvest
September-OctoberGrapes reach full dark purple color and maximum sweetness. Clusters are heavy with ripe fruit ready for picking.
Harvest when fully colored and tasting sweet; grapes don't ripen further after picking. Use pruning shears to cut clusters. Store in cool location. Begin reduced watering post-harvest.

Harvest Tips
Grapes are ready to harvest in late September through October when fully dark purple and sweet to taste. Taste a grape or two to confirm ripeness before harvesting the entire cluster. Use clean pruning shears to cut clusters at the stem, leaving a small portion of stem attached. Handle gently to avoid bruising. Harvest in dry conditions for best storage. Grapes do not ripen further after picking, so timing is important. Can be harvested for fresh eating, juice, or jam production.
