Growing tomatoes and kohlrabi together can be an interesting and productive gardening endeavor. Here, I’ll provide you with a guide on how to grow tomatoes at home, and you can adapt the principles to integrate kohlrabi or other companion plants as appropriate.

Growing Tomatoes:

Materials Needed:

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


  1. Selecting Tomato Varieties:
    • Choose tomato varieties based on your preferences and the available space. Determinate varieties are more compact and may be suitable for containers.
  2. Choosing Containers or Garden Beds:
    • If growing in containers, select large containers with good drainage. If growing in the ground, prepare well-draining garden beds.
  3. Preparing the Soil:
    • Use a well-draining potting mix for containers or amend garden soil with compost to improve fertility and drainage.
  4. Planting Seeds or Seedlings:
    • If starting from seeds, start them indoors 6-8 weeks before the last frost. Transplant seedlings into containers or garden beds once they have a few sets of true leaves.
    • If using seedlings, plant them at the recommended spacing, ensuring good air circulation between plants.
  5. Providing Support:
    • Install tomato cages or stakes at the time of planting to provide support as the tomato plants grow. This helps prevent sprawling and keeps the fruit off the ground.
  6. Fertilizing:
    • Mix organic fertilizer into the soil before planting and provide additional fertilizer throughout the growing season according to package instructions.
  7. Watering:
    • Keep the soil consistently moist, especially during dry periods. Water at the base of the plants to avoid wetting the foliage, which can reduce the risk of diseases.
  8. Mulching (Optional):
    • Mulch around the base of the tomato plants to retain moisture, suppress weeds, and regulate soil temperature.
  9. Sunlight:
    • Place the containers or garden beds in a location that receives at least 6-8 hours of direct sunlight per day. Tomatoes thrive in full sun.
  10. Pruning (Optional):
    • Optionally, prune the lower leaves of the tomato plants to improve airflow and reduce the risk of diseases. Indeterminate varieties may also benefit from pruning to manage growth.
  11. Harvesting:
    • Harvest tomatoes when they reach the desired size and color. Use a sharp knife or scissors to cut them from the plant.

Companion Planting with Kohlrabi:

If you want to grow kohlrabi alongside tomatoes, consider these additional steps:

  1. Selecting Kohlrabi Varieties:
    • Choose kohlrabi varieties suitable for your climate and space. Kohlrabi has a compact growth habit and can be grown in proximity to tomatoes.
  2. Interplanting:
    • Plant kohlrabi seeds or seedlings around the base of the tomato plants. Ensure proper spacing to avoid overcrowding.
  3. Caring for Kohlrabi:
    • Kohlrabi prefers cool weather. Water regularly and provide shade during hot periods if needed.
  4. Harvesting Kohlrabi:
    • Harvest kohlrabi bulbs when they reach the size of a tennis ball. Cut them at ground level.

Remember to monitor both tomatoes and kohlrabi for pests and diseases, and take appropriate measures to address any issues promptly. By combining tomatoes and kohlrabi, you can create a diverse and productive garden.
