SEED SAVING GUIDE
The Organic Seed Alliance have developed a comprehensive guide to seed saving, which outlines the basic knowledge needed for seed production, relevant to farmers and home gardeners alike. Click here to download the pdf.

CLIMATE & DAYLIGHT
The Organic Seed Alliance have a helpful document here, with guidelines for seed production in adverse weather conditions. The guidelines are aimed at the Northwest region of the USA, which has a fairly similar climate to the UK.
Daylight hours is another important factor when saving seed and growing certain crops. Light and therefore latitude makes a difference to the crop’s ability to flower and produce seed. Johnny’s Seeds has a good explanation on their website here. High Mowing Organic Seeds also have a good article on the effect of daylight hours, also called “photoperiodism”, here, with a useful table showing Long Day, Short Day and Neutral Plants.
SEED ECONOMICS FOR GROWERS
Growing for seed brings diversity to the garden. It not only produces beautiful flowers, but these flowers attract more biodiversity and provide for the many pollinators. This is more than enough reason to grow for seed. But it can also be an added income to a farm business and in many cases can be very profitable.
Here are some videos and examples of seed producers from the US and Canada on the business side of seed production…
