Grow tomatoes and eggplants together: the ultimate companion planting guide

Eggplants and tomatoes, two beloved nightshade vegetables, grace countless gardens and dinner plates. But can these two solanaceous plants coexist peacefully in the same growing space? The answer to the question “can eggplant grow with tomatoes” is a resounding yes, with certain considerations.

Benefits of Companion Planting

Companion planting, the practice of growing different species together for mutual benefit, offers several advantages when it comes to eggplants and tomatoes:

• Improved pollination: Eggplants attract pollinators that also benefit tomato flowers, enhancing fruit set.
• Pest deterrence: The strong scent of eggplants can deter certain pests, such as aphids, that may target tomatoes.
• Nutrient exchange: Eggplants and tomatoes have different root systems, allowing them to access nutrients from different soil depths.

Considerations for Companion Planting

While eggplants and tomatoes can grow together, it’s essential to consider the following factors:

• Spacing: Allow ample space between plants to prevent crowding and promote air circulation.
• Water: Both eggplants and tomatoes require regular watering, but avoid overwatering, which can lead to disease.
• Fertilization: Fertilize regularly with a balanced fertilizer to support plant growth and fruit production.
• Disease control: Rotate crops annually to minimize disease buildup and improve soil health.

Growth Habits and Requirements

Eggplants:

• Warm-season vegetables that thrive in temperatures between 65-85°F (18-29°C).
• Require well-drained, fertile soil with a pH of 6.0-6.8.
• Grow upright, reaching heights of 2-3 feet (0.6-0.9 meters).

Tomatoes:

• Warm-season vegetables that prefer temperatures between 70-85°F (21-29°C).
• Require well-drained, fertile soil with a pH of 6.0-6.8.
• Indeterminate varieties grow tall and require staking or trellising.

Planting and Care

• Start seeds indoors: 6-8 weeks before the last frost date.
• Transplant outdoors: When seedlings have 2-3 sets of true leaves.
• Space plants: 18-24 inches (45-60 cm) apart for eggplants, 2-3 feet (0.6-0.9 meters) apart for tomatoes.
• Water regularly: Keep soil moist but not soggy.
• Fertilize: Every 2-3 weeks with a balanced fertilizer.
• Mulch around plants: To retain moisture and suppress weeds.

Harvesting and Storage

• Eggplants: Harvest when fruits reach their desired size and color. Cut with a sharp knife.
• Tomatoes: Harvest when fruits are fully ripe and slightly soft to the touch.

Troubleshooting

• Yellowing leaves: Nutrient deficiency or overwatering.
• Blossom end rot: Calcium deficiency. Water regularly and apply calcium supplements.
• Aphids: Use insecticidal soap or neem oil.
• Spider mites: Spray with water or use horticultural oil.

Wrap-Up

With proper planning and care, eggplants and tomatoes can thrive as companion plants. By harnessing their symbiotic benefits and addressing their specific needs, you can enjoy a bountiful harvest of both these delicious and nutritious vegetables.
