Harvesting Your Broccoli Seeds

To harvest your broccoli plant seeds pull the entire plant from the soil and allow the pods to dry on the stalk. You will need to be extra careful to get them out of the pod without destroying them. Broccoli seeds are very small; in fact, some people do not recognize them when they see them for the first time. Most people mistake them for tiny bits of dirt.

Your first task in harvesting your seeds is to save the pods. Allow your pods to dry, then pound them open to get the seeds out. Gently pound them, so you don’t crash the seeds. Besides pounding, you can twist open the pods and remove the seeds putting them on a clean sheet of paper. Though this process may take longer than pounding, it ensures that your seeds do not get damaged or broken.

To be able to see these seeds as they fall from the pods, you can lay them out on white paper or a white sheet to differentiate them from dirt.

Once you have your seeds out of the pot, dry them for several days, ensuring that the wind does not suit them away or the birds does not eat them. You now have ready seeds for your next planting season. How cool is that?

Storing Your Harvested Seeds

Once you have harvested your seeds, it is extremely important to preserve their viability by taking proper care.

How long do broccoli seeds last?  Broccoli seeds are best preserved by storing them in a cool, dry place where they should remain viable for up to 2 years. Seeds that are older than 2 years may not be viable; however, before throwing them out, you can test to see if they float in water, meaning they will not germinate. Seeds that sink are most likely viable and can do well when planted.

If you are not able to use all the seeds you harvest, you can share them with friends and family for planting the next season.

Store your seeds in paper packets to protect them from moisture or pest damage that can ruin them. Store the packets in a glass or plastic container, tightly sealing them with a lid to keep them safe until the next planting season.

Mark your pockets with a cultivar name and harvesting date before storing so that you know which ones to use first.
