Film canisters are a great place to store pollen in. You can save pollen in a canister for the next harvest. Pollen can be stored in the freezer for around 18 months. The odds of having pollen keep though are slim. Pollen is best used up to 6 months. The pollen can be extracted from the male flower as soon as the flowers are ready to open. You will see the male flower open out from its pod. It is best to gather pollen after it falls from the pod onto the leaves. Simply shake the pollen onto the female flowers to pollinate them.
