Cubanelle peppers need a head start in regions with cool springs. Begin seeds indoors 8â10 weeks before the last expected frost. Use a bright window or grow lights for best results.
- Seed Depth: 1/4 inch in seed starting mix
- Temperature: 70â85°F for germination
- Light: 14â16 hours/day from fluorescent or LED grow lights
- Watering: Keep soil slightly moist, not soggy
- Transplant Time: Harden off 1â2 weeks before planting outside
Transplanting Outdoors
- Location: Full sun (minimum 6 hours direct sunlight)
- Spacing: At least 18â24 inches between plants
- Soil: Fertile, well-draining loam, amended with compost
- Temperature: Soil at least 65°F; donât rush transplanting
Container Growing
- Pot Size: Minimum 5 gallons, with drainage holes
- Soil: High-quality potting mix enriched with organic material
- Advantages: Easier to move; great for patios; allows control over soil and moisture
Care and Maintenance
Sun and Temperature
- Sunlight: Give plants all-day sun for optimal growth and fruit production
- Temperature: Optimal daytime 70â85°F; protect from frost
Watering
- Regular Watering: Keep the soil evenly moist, avoid waterlogging
- Mulch: Use organic mulch to retain moisture and suppress weeds
- Deep Watering: Water deeply to encourage deep root growth

Fertilizing
- Initial Soil Prep: Work compost or a tomato/pepper fertilizer into soil before planting
- Feed During Growth: Fertilize every 4â6 weeks during the growing season; products like Espoma Tomato-tone are effective
Pruning and Training
- Minimal Pruning: Remove leaves that touch the ground to prevent disease
- Avoid Topping: Especially in short growing seasons, topping slows fruit production
- Support: Cage or stake taller plants to prevent stems from bending under fruit weight
Pest and Disease Management
Common Pests
- Aphids: These sap-suckers can cause leaf curling; hose off, introduce ladybugs, or use insecticidal soap
- Whiteflies: Tiny, fluttering pestsâyellow sticky traps can help
- Pepper Weevil: Tiny beetles that burrow into fruit; remove and destroy infested peppers
Common Diseases
- Blossom-End Rot: Brown black spots on fruit baseâconsistent watering and calcium-rich soil helps prevent
- Root Rot: Caused by overwatering/poor drainageâensure well-drained soil and containers
- Tobacco Mosaic Virus: Distorted, mottled leavesâavoid handling tobacco, rotate crops, remove infected plants
Growth Cycle: From Seed to Harvest
- Germination: 7â14 days after sowing
- Transplant: 8â10 weeks after sowing, once danger of frost has passed
- Flowering: 1â2 weeks after transplant
- Fruit Set: Initial fruit appear 2â3 weeks after flowers
- Maturity: 60â75 days from transplanting, depending on variety and conditions
