Save seeds from your garden

Seeds from heirloom tomato bought in store

Saving seeds has been the foundation of farming since it began thousands of years ago.  Seed saving is easy and saves you money.  Always save the seed from the best vegetable you grew! Or the tastiest you buy at the farmers market or store.  

Pick the fruit or plant that has the characteristics you want to grow again.  The one that was the biggest or had the best taste or produced the most or produced the longest or gave you harvests the earliest or was the most drought or pest resistant.  Whatever characteristic that you want to have in your garden next year is the plant's seeds you want to save from this year.

One caveat, you cannot get "true to parent" plants from hybrids.  If they grow, they will often be totally different than the parent or could get weaker with each generation.  You need “open pollinated” or heirloom vegetables for the seed to for sure produce a baby like the parent.  You can always save seed from hybrids to try as an experiment, but don't be surprised if it is very different from the parent plant.

What do the terms GMO, natural, heirloom, organic, hybrid really mean?

It doesn't cost a thing to save seeds from store bought veggies or fruits you like and you can end up with some great plants for your garden!  To be sure that the seeds you save will come back true to the parent, heirloom is a sure bet.  One of my favorite paste tomatoes is one I saved the seed from a tomato bought from the store.

For garlic, you save the best, biggest cloves.  You divide up the garlic head into individual cloves and plant them in the fall when it cools off.  Typically, sometime in October or November.  Most store bought garlic has been treated to prevent them from sprouting so you may or may not have luck using the ones from the grocery store.  Organic garlic is not treated.  Your farmers market is also a great place to get garlic well suited for your area.  October is prime time to plant garlic

In our garden, seeds can be saved from tomatoes, peppers, cucumbers, zucchini, lettuce, broccoli, cilantro, dill, celery, borage, salad burnet, garlic, okra, Egyptian walking onions (bulblets), basil.  I have many zinnia, amaranth, chervil, garlic chives, marigold and basil "volunteers" in the garden every year from seeds dropped by the plant last fall.

Do not save seeds from any diseased plant as the disease can be in the seed itself and passed to the new plant.  You wouldn't want to save seed from a plant that is susceptible to disease any way.  You want to save seeds from plants that thrive in your garden conditions.

For peppers, squash and tomatoes, just scoop out the seeds, lay them on a paper towel on a plate and let them dry completely.  Some suggest for tomato seed to put them in water and let them ferment a bit.  The ones that sink are the ones you want to keep for planting, not the ones that float.  After drying, I put in plastic baggies and keep in the frig to prolong seed life.  Don't forget to label the variety and date saved.

I have finally found/grown two kinds of sweet peppers that produce well.  I'll keep saving the seed and growing them out.  They are now a mainstay for my garden.  This year I had great luck with California bell peppers so I will try these again next season.  Peppers are for every taste and garden

Many greens, like chard, parsley, lettuce, broccoli, will shoot a large stalk up then flower.  This is called "bolting."  The easiest thing to do is to let the seeds form, cut the stalk, then put the stalks with seed heads attached into a paper bag.  Let them dry thoroughly, then shake the seeds out.  Some may require that you roll the seed heads between your fingers to free the seed.  

You can actually re-sow seeds from cool season crops like lettuce, cilantro, parsley, chard, chives and get a second fall/winter harvest!  I re-sow seeding about every other week starting the first of September.  In about two weeks, you will have sprouting greens.  When they have grown a bit more, I will separate and transplant into pots and the garden.  I like starting seeds in long narrow pots what are self-watering to be able to move easily to the best growing conditions.  Can also move under the portable greenhouse when it gets cold.

I put my dried seeds in labelled ziplock bags and store them in the crisper, include the seed type, descriptor and date.  A picture of the plant can be helpful to remember the plant the seed belongs to.  Fun gift to give, too.  The seeds last for years this way!

This year, I have saved seeds from the best tasting butternut squash I have grown ever, Giant Blue Feather lettuce, Egyptian walking onions, garlic, orange Cactus and California Giant zinnias, cockscomb, Turkish Orange and Antigua eggplant, my bushiest sweet basil and Cardinal basil, Purple Yard Long and Blauhilde pole beans, Christmas Speckles lima beans, and Jigsaw pepper seeds.  I have left my celery, Red Malabar spinach, and some Giant Blue Feather lettuce plants go to seed for volunteers in the spring.

Our local Master Gardener group is looking to start a seed library (basically a seed swap station) in our local library.  I'll have plenty to use for my garden and give to the seed library.
