Collecting and Saving Lettuce Seeds

Most varieties of lettuce are grown all year round however some varieties are easier to grow and collect seeds from than others.

Cos lettuce is one of the hardiest varieties which grows well in a wide variety of conditions. It has a high nutrient value and germinates easily from seed sown direct in the garden.

Saving Lettuce Seeds

To improve your crop from year to year always save seeds from a disease-free plant with a good growth rate, size and taste. Simply taste one of the leaves from each healthy plant before deciding on which plant to let flower.

  3. Leave to Dry

    Place upside down in a bag with the flowers at the bottom. Leave in an area with good air circulation to completely dry leaving the top of the bag open.

  4. Discard the Stems

    Once dry shake the stem to release any remaining seeds then discard. Pour the contents of the bag onto a plate. There will be a mix of seeds and dried flowers.

    Shake the plate back and forth so the seeds settle to the bottom then gently blow the dried flowers off the top. Blow too hard and you will blow the seeds off the plate too.
