Starting your own seed collection is easy!

I gather most of my seeds in the fall and plant them indoors in late winter so I might have a longer growing season. It is best to wait until plants wither and dry up (since the nutrients in their seeds will be more concentrated). Be sure to air dry them well so they don't get moldy. Some seeds will only sprout after freezing temperatures during the winter. You can simulate this by placing them inside a breathable paper container. Tomatoes are a very temperamental seed since you need to soak them in water 3 days in order to dissolve the outer membrane of their seeds before you dry them. Label and store your seeds in paper envelopes and place those inside a large bug and rodent-proof container. I recommend searching the internet for detailed instructions about how each plant can be propogated.
