Growing tomatoes is a rewarding experience, but achieving large fruits and an abundant harvest can sometimes be challenging. One simple, cost-effective way to improve your tomato plants is by using eggshells. Here’s how eggshells can benefit your tomato plants and how to use them effectively.

Benefits of Using Eggshells

  1. Calcium Source: Eggshells are rich in calcium, an essential nutrient for tomato plants. Calcium helps prevent blossom end rot, a common issue in tomatoes where the bottom of the fruit turns black and rots.
  2. Soil Aeration: Crushed eggshells improve soil structure and aeration, allowing roots to grow more efficiently and absorb nutrients better.
  3. Pest Deterrent: Sharp eggshell pieces can deter soft-bodied pests like slugs and snails, protecting your plants from damage.
  4. Natural Fertilizer: As eggshells break down, they release essential minerals into the soil, acting as a slow-release fertilizer.

How to Prepare Eggshells for Your Garden

  1. Collect and Clean: Save eggshells from your kitchen. Rinse them thoroughly to remove any egg residue and let them dry completely.
  2. Crush: Once dried, crush the eggshells into small pieces. You can use your hands, a rolling pin, or a food processor for a finer consistency.
  3. Store: Store the crushed eggshells in a container until you’re ready to use them in your garden.

How to Use Eggshells in Your Tomato Garden

  1. Planting: When planting tomato seedlings, sprinkle a handful of crushed eggshells into each planting hole. This provides a direct source of calcium to the young plants.
  2. Top Dressing: Scatter crushed eggshells around the base of established tomato plants. As they decompose, they will slowly release calcium into the soil.
  3. Compost: Add eggshells to your compost pile. They will break down over time, enriching your compost with calcium and other minerals.
  4. Liquid Fertilizer: For a quick calcium boost, soak crushed eggshells in water for a few days to create a liquid fertilizer. Use this water to irrigate your tomato plants.

Tips for Using Eggshells

  • Consistent Application: Regularly apply eggshells throughout the growing season to maintain soil calcium levels.
  • Combine with Other Amendments: Eggshells work well with other organic amendments like compost and well-rotted manure.
  • Monitor Soil pH: While eggshells can help neutralize acidic soil, it’s essential to monitor your soil’s pH to ensure optimal growing conditions for tomatoes.


Using eggshells in your tomato garden is an easy and sustainable way to boost plant health and increase your yield. By providing a steady source of calcium and improving soil structure, eggshells help your tomato plants thrive. Give this simple technique a try and enjoy larger, healthier, and more abundant tomatoes this season!
