This is a really easy way to test the viability of seeds at home
Materials needed: tissue paper, seeds, small plastic bag, water
1. Moisten tissue paper and place 25 seeds in a zigzag, 1cm from the top and 2cm from the sides
2. Fold the tissue over, bringing the bottom edge to the top
3. Roll into a sausage
4. Place in a small plastic bag and leave in a warm place for a week or two (depending on the seed)
5. Remove from plastic bag, unroll and unfold tissue. Count germinated seeds – multiply by four to get a percentage germination
