1. Collect seed pods or mature fruits

collect seed pods or mature fruits
Collect mature seed from seedheads or ripe fruit, preferably from plants that are healthy and vigorous. It is all about the correct timing - seeds must be collected before they open and shed their content, but should not be harvested when immature as they will not produce viable seed. Ripe seedheads are often indicated by a change in colour from green to black, brown or red. Tip: Pick seedheads from non-fruiting plants on a dry day to speed up the drying process.

2. Extract the seeds

When the seedheads have dried, extract seeds from the pod, cone or capsule by gently shaking, or crushing it. Scoop out seeds from fleshy fruits using a spoon.

3. Clean the seeds

Remove any material (chaff) attached to the seed as this material is prone to rotting or moulding and could potentially harbour pests and diseases. If you are extracting seeds from fleshy fruits, rinse away the pulp in cold water and leave the seeds out to dry on a paper towel.

4. Place in an airtight container

place in an airtight container
When the seeds have dried and there is no sign of excess moisture, place the seeds in an airtight container. Excess humidity can cause the seed to deteriorate or die due to fungal disease or rotting so, to remove any excess moisture, store the seeds with cinnamon (a natural desiccant).

5. Label it

Label the container with the plant name date of harvest.

6. Store it

Place the container in a cool, dark location. Use the seeds in the following season - every year the seed quality will deteriorate and fewer plants will grow from those seeds. Happy saving!
