Saving Tomato Seeds

May 2, 2020

The year 2020 can easily be called the year of the “Big Vegetable Gardening Revival”. Worldwide, millions of people discover the joy and comfort that growing our own food can give us. If you too want to learn how to grow your own fresh food at home, let’s start at the very beginning: the seed!

What’s the learning?

This lesson is about “seed saving”. That means we collect the seeds from this season’s crop to prepare for next season’s harvest. It is about thinking ahead. Local seed saving is important because we get the seeds from plants that are well adapted to our local climate. Doing this supports genetic diversity and resilience in food crops, and reduces food miles. Saving seeds from tomatoes is easy and fun. Check out the video to see how to do it!

What you need:

  • The yummiest, juiciest, ripest tomato you can find, preferably locally grown
  • Toilet paper
  • A knife
  • A pen
  • An envelope

What to do:

  1. Cut your tomato in half.
  2. Scoop out seeds individually and place them on the tissue paper about 2cm apart in a 4 by 4 square. 
  3. Write on the toilet paper the name of the seeds and the date.
  4. Leave to dry in a warm place for three days.
  5. Place the seed paper in an envelope, folding if necessary. Write on the envelope which seeds they are and the date again.
  6. Store in a dry, cool, darkish place.
  7. Enjoy the rest of the tomato.

The following spring:

  1. Fill a planting pot with seedling mix.
  2. Cut the toilet paper to size if necessary.
  3. Place your seed paper in the pot seeds up.
  4. Cover with 5mm of seedling mix.
  5. Water.
  6. Place in a warm sunny spot, for most people that would be a sunny window sill, keeping it moist. 
  7. You will then have the next year’s seedlings.
