Growing tomatoes and eggplants together can be a surprising and productive gardening approach. Both belong to the same plant family (Solanaceae) and have similar growing requirements. Here’s a step-by-step guide on how to grow tomatoes and eggplants together:

Materials Needed:

  1. Tomato and eggplant seeds or seedlings
  2. Large containers or garden beds
  3. High-quality potting mix or well-draining garden soil
  4. Support structures (stakes or cages)
  5. Organic fertilizer
  6. Mulch (optional)
  7. Watering can or hose
  8. Full-sun location


  1. Selecting Varieties:
    • Choose tomato and eggplant varieties that are suitable for your climate and space. Compact or determinate varieties work well for containers.
  2. Preparing Containers or Garden Beds:
    • Use large containers or prepare garden beds with well-draining soil. Ensure there is enough space for both tomatoes and eggplants to grow.
  3. Planting Seeds or Seedlings:
    • If using seeds, start them indoors several weeks before the last frost. Transplant seedlings outdoors once they are robust.
    • If using seedlings, transplant them into the containers or garden beds according to the recommended spacing.
  4. Adding Support Structures:
    • Install stakes or cages for both tomatoes and eggplants to provide support as they grow. This helps prevent sprawling and keeps the fruits off the ground.
  5. Fertilizing:
    • Mix organic fertilizer into the soil before planting and provide additional fertilizer throughout the growing season according to package instructions.
  6. Mulching (Optional):
    • Mulch around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature. This is especially helpful in containers.
  7. Watering:
    • Keep the soil consistently moist. Water deeply and regularly, especially during dry periods. Avoid watering the foliage to reduce the risk of diseases.
  8. Sunlight:
    • Place the containers or garden beds in a location that receives at least 6-8 hours of direct sunlight per day.
  9. Pruning (Optional):
    • Optionally, prune the lower leaves of both tomatoes and eggplants as they grow to improve air circulation and reduce the risk of diseases.
  10. Harvesting:
    • Harvest tomatoes when they reach the desired size and color. For eggplants, harvest when the fruits are glossy and firm. Regular harvesting encourages more production.
  11. Pest and Disease Management:
    • Keep an eye out for common pests and diseases that affect tomatoes and eggplants. Treat any issues promptly with organic methods or appropriate remedies.

Growing tomatoes and eggplants together not only maximizes your gardening space but can also create a visually appealing and bountiful harvest. Just ensure that both plants receive the care they need, and you’ll enjoy the rewards of homegrown tomatoes and eggplants.
