Fig Growing: Intermediate Techniques for Better Harvests

Introduction

You've grown fig trees successfully and want to improve your harvests, try new varieties, or expand your growing techniques. This intermediate guide covers variety selection in depth, training systems including espalier, comprehensive pest and disease management, and strategies for maximizing fruit production.

Advanced Variety Selection

Understanding Fig Classifications

Variety Selection by Climate

Hot, Dry Climates (Zones 9-11):

Humid Climates (Southeast US):

Cool Climates (Zones 6-7):

Breba vs. Main Crop

Training Systems

Open Center (Vase) Form

Best for: Most in-ground trees; maximum light

Structure:

• 3-5 main scaffold branches
• Open center for light penetration
• Height managed at 8-15 feet

Training steps:

1. First dormant season: Select 3-5 well-spaced scaffolds
2. Remove central leader
3. Head back scaffolds by 1/3
4. Years 2-3: Develop secondary branching
5. Maintain open center annually

Bush Form

Best for: Cold climates; dieback protection

Advantages:

• Multiple stems from base
• If some die back, others survive
• Lower fruit = easier harvest
• Self-renewing

Management:

• Allow 5-8 main stems
• Remove oldest stems every few years
• Maintain at 6-10 feet

Espalier

Best for: Small spaces; cold climates (wall heat)

Forms:

• Fan (most common for figs)
• Horizontal tiered
• Belgian fence

Setup:

1. Install support wires 18" apart
2. Train young branches to wires
3. Prune to maintain 2-dimensional form
4. Remove growth pointing away from wall

Advantages against walls:

• Extra warmth (microclimate)
• Protection from cold winds
• Easier winter protection
• Space efficient

Container Training

Size progression:

Pruning for containers:

• Keep compact (6-8 feet)
• Focus on productive wood
• Remove interior crossing branches
• Summer prune for size control

Integrated Pest Management

Disease Management

Fig Rust (Cerotelium fici)

Symptoms:

• Yellow-green spots on leaves (upper surface)
• Brown spores on leaf undersides
• Leaf yellowing and premature drop

Management:

Anthracnose (Colletotrichum gloeosporioides)

Symptoms:

• Sunken spots on fruit with pink spores
• Dark-edged spots on leaves
• Fruit drop and mummification

Management:

• Improve air circulation (pruning)
• Avoid overhead irrigation
• Remove infected fruit immediately
• Copper-based fungicide at early stages

Fig Mosaic Virus

Symptoms:

• Yellow mottling on leaves
• Spotted, stunted fruit
• Premature fruit drop

Management:

• No cure; remove infected trees
• Control fig mite vector (Aceria ficus)
• Use virus-free nursery stock
• Sanitize pruning tools

Pest Management

Dried Fruit Beetle

Problem: Carries souring organisms into fruit

Solution:

• Choose closed-eye varieties (Celeste, Alma)
• Harvest promptly when ripe
• Remove fallen fruit

Fig Beetle (Cotinis mutabilis)

Damage: Adults feed on ripe fruit

Management:

Spider Mites

Signs: Stippled leaves; fine webbing

Control:

• Spray with water to dislodge
• Horticultural oil
• Encourage predatory mites
• Avoid dusty conditions

Root-Knot Nematodes

Signs: Stunted growth; galled roots

Prevention:

• Resistant rootstocks where available
• Soil solarization before planting
• Marigold cover crop
• Avoid planting where known issue exists

Maximizing Fruit Production

Factors Affecting Yield

Improving Fruit Size

1. Thin fruit clusters if very heavy set
2. Adequate irrigation during cell expansion
3. Moderate nitrogen (not excessive)
4. Remove breba crop to boost main crop size

Extending the Harvest

Succession of varieties:

Propagation

Hardwood Cuttings (Easiest Method)

Timing: Late winter (dormant)

Process:

1. Select pencil-thick, 1-year-old wood
2. Cut 8-10" sections with 3-4 nodes
3. Make angled cut at top, flat at bottom
4. Dip in rooting hormone (optional but helpful)
5. Plant in well-draining medium
6. Keep moist but not wet
7. Roots in 4-8 weeks
8. Transplant when established

Success rate: 70-90%

Air Layering

Timing: Early summer

Process:

1. Select pencil-thick branch
2. Girdle bark (remove 1" ring)
3. Apply rooting hormone
4. Wrap with moist sphagnum moss
5. Cover with plastic wrap
6. Roots develop in 6-10 weeks
7. Cut below roots and pot up

Record Keeping

Track annually:

• Variety performance
• Harvest dates and yields
• Pest/disease observations
• Pruning dates
• Weather events (frost, heat waves)
• Winter protection (if used)
• Fertilization schedule

Conclusion

Successful intermediate fig growing requires understanding variety characteristics for your climate, implementing appropriate training systems, and maintaining proactive pest and disease management. The investment in proper variety selection and training pays dividends in consistent, high-quality harvests for decades.
