Growing Guide: Carlos Grape

Our trellised Carlos Grape Vines are shipped in our X-Large (3 gallon) recyclable nursery pots or plantable burlap pots when possible. Plantable pots can be planted directly in the soil, promoting strong root growth and ensuring an eco-friendly start.

Climate and Soil Requirements

  • Climate: Carlos Grapes thrive in warm, humid climates typical of the southeastern United States. They are best suited for USDA hardiness zones 7-9. The vines require a long growing season with hot, humid summers and mild winters.
  • Soil: Prefers well-draining, sandy or loamy soil with a slightly acidic to neutral pH (5.5-7.0). Amend the soil with organic matter to improve fertility and drainage if necessary.

Planting

  1. Location: Choose a sunny location that receives at least 6-8 hours of direct sunlight daily. Ensure the site has good air circulation to prevent fungal diseases.
  2. Soil Preparation: Prepare the soil by tilling and adding compost or organic matter to enhance fertility and drainage.
  3. Planting Time: Plant young vines in the spring after the last frost or in the fall in milder climates. Space plants 10-15 feet apart to allow adequate room for growth and air circulation.
  4. Trellis System: Install a trellis or arbor to support the vigorous growth of the vines. This will help improve air circulation and sunlight exposure, reducing the risk of disease.

Watering

  • Establishment Phase: Water regularly to keep the soil consistently moist but not waterlogged during the first year. Consistent moisture is crucial for young plants.
  • Mature Plants: Once established, Carlos Grapes are somewhat drought-tolerant. Water deeply and less frequently, allowing the top inch of soil to dry out between waterings.

Sunlight

  • Full Sun: Ensure the vines receive at least 6-8 hours of direct sunlight daily for optimal growth and fruit production.

Fertilizing

  • Growing Season: Apply a balanced, slow-release fertilizer in early spring as new growth begins. Supplement with a high-potassium fertilizer during the fruiting period to enhance fruit development.
  • Frequency: Fertilize every 4-6 weeks during the growing season. Reduce feeding in the fall and avoid fertilizing in winter.

Pruning and Maintenance

  • Routine Pruning: Prune in late winter or early spring before new growth begins. Remove dead, diseased, or weak branches to maintain the vine's shape and improve air circulation.
  • Fruit Production: Regular pruning helps encourage new growth and increased fruit production. Proper training and pruning are essential for managing the vine's vigor and maximizing yield.

Pest and Disease Management

  • Common Pests: Monitor for pests such as grape berry moths, Japanese beetles, and aphids. Use insecticidal soap or neem oil to control infestations. Encouraging beneficial insects can also help manage pests.
  • Diseases: Watch for signs of fungal diseases such as powdery mildew and black rot. Ensure proper spacing, good air circulation, and avoid overhead watering to reduce disease risk. Apply fungicides if necessary.

Harvesting Fruit

  • When to Harvest: Grapes are ready to harvest when they reach full color and are slightly soft to the touch. Taste test for sweetness before harvesting.
  • How to Harvest: Use pruning shears to cut the clusters from the vine, taking care not to damage the plant. Handle the grapes gently to avoid bruising.
