Farm Radio International offers helpful tips on planting and re-stocking the seed. You may find the information that they provide on planting and re-stocking seed to be very helpful:
NOTE: If more than half the seeds do not sprout then you must plant out your seed, and collect and save the seed from those plants. If more than half of the seeds sprout, you know that the seed is still healthy, and it isn't necessary yet to add more seed to your stock.
You can add more seed to your community seed bank by collecting and storing new seed or by planting out the original seed, allowing its plants to grow, and collecting and storing the second generation of seed.
If you decide to plant out your original seed remember to:
After planting out seeds, collect a large number of seeds from the plants, including seeds from plants that look strong and weak, tall and short, with or without fruit. And keep your seed stocks dry, cool, and safe from insects.
For more information about starting a community seed bank, or about collecting, drying and storing seeds, ask farmers for their ideas, or contact your local agricultural office or community organizations.
Keep protecting rare and local crops and useful plants. Remember they are the future of your farm and your family.
