/h3>/h3>In this Seed Saving class from the UC Cooperative Extension Master Gardeners of Stanislaus County, you'll learn:
- What types of seeds to save and the difference between heirlooms and hybrid seeds.
- How flowers are pollinated and how seeds develop.
- How far apart to plant varieties of vegetables to ensure seed purity.
- How to save seeds and how long saved seeds last.
During class, you'll have a hands-on experience of separating flower and vegetable seeds from "chaff,*" and labeling to take home to your garden. Please join us at one of our classes at a local Stanislaus County library near you.
We are also excited to announce that classes are starting this month at the Waterford Library branch!

*chaff is the extra stuff growing around the seed like the spent flowers, pods, etc.
- Seeds and plants saved become acclimated to our environment, climate
- There is a greater variety of vegetables to grow
- There may be more genetic diversity when growing old-time veggies
- It is can be cost effective due to higher seed prices
Hybrids vs. Heirlooms
There are two major types of seeds: Hybrid and Heirloom seeds
- Hybrid seeds have been cross pollinated from two different varieties in the same plant species. They are crossed to produce seeds that carry desired characteristics or appearances.
- Seeds saved from hybrid plants will revert back to their parent plants.
- Heirloom Seeds are non-Hybrid, and open pollinated.
- Heirloom Seeds are usually more than fifty years old and have been passed down from generation to generation
- If you plant an Heirloom seed that you have saved from an Heirloom plant, it will grow true to the parent plant.
Spacing plants to prevent cross-pollination
How long do seeds last?
This is dependent on the type of seed, but also on how they are taken care of after you save them. To ensure saved seeds will sprout in the future, store them in a cool, dry place away from moisture, heat, and light.
Common Beans
The seed is the mature bean. Allow the bean pod to dry on the vine. If growing more than one variety, isolate by at least 20 feet.
- Harvest the dried bean pods and place in a paper bag.
- Dry for a week or more before separating the bean from its pod.
- Grow and harvest from at least 10 plants of the same variety for diversity.
- Seeds can last up to 4 years.
Eggplant
Allow several fruits from at least 10 plants to ripen far past the edible stage. The skin will become a dark yellow or yellowish-brown color. If growing more than one variety, isolate by at least by 50 feet.
- Mash the pulp by hand as best as you can. The seeds are hard, smooth and plump and won't damage easily.
- Toss seeds and pulp into a bucket of water and stir until pulp separates from the seeds. Seeds will sink.
- Rinse until the water comes out clear. Pour seeds through a screen, spread them in a thin layer and dry for about 3 weeks.
- Seeds can last 3-6 years
Garlic
- After harvest, store garlic at room temperature to prevent premature sprouting.
- Plant from your crop every year.
Lettuce
Seeds are very easy to save. Allow a dozen plants to grow, unharvested, through the spring and summer. They will “bolt” (send up seed heads). Isolate by 20 feet if growing more than one variety. Once the seed heads are a yellowing-tan color and very dry, they are ready to save.
- Cut at the stem and place in a paper bag. Once dry, crush the heads and sift to separate the seeds from the chaff.
- Harvest from at least 10 plants of the same variety.
- Seeds can last 2-4 years.
Okra
Pods should be left on the plants until fully mature. Okra is self-pollinating but will cross via bees if two varieties are planted near each other. Plant one variety to ensure purity.
- Pick just as the seeds begin to split.
- Clip and store in paper bag for a few weeks.
- Seeds can last up to 3 years.
Peas
Peas are self-pollinating, however, keep favored plant 20 feet away if growing more than one variety.
- Allow pods to slightly dry on the vine before harvesting.
- When picked, place in a paper bag and allow to dry further for a week or two.
- Thresh them from the pod, and store in a jar or envelope.
- Seeds can last up to 5 years
Peppers
- Cut open the ripe fruit, scrape out the seeds and let dry on a paper plate for a week before storing in a jar.
- Seeds can last up to 2 years.
Tomatoes
Tomatoes are mostly self-pollinating, but to ensure purity, separate the favored plant by 10 feet. Allow the fruit to fully ripen on the stem before harvesting.
- Cut the tomato open and scoop out the seeds.
- Place the seeds in a jar of water and allow to ferment until a white mold forms on top of the water.
- During this process, cover the top of the jar with paper towel to keep flies out.
- Rinse the contents of the jar with water until it comes out clear.
- Allow seeds to settle between rinses. Good seeds will sink to the bottom each time.
- Spread seeds out on a paper plate and allow to dry for 3-4 days before storing in a paper envelope.
- Seeds can last up to 5 years.

Hopefully, these suggestions will inspire you to begin the exciting adventure of saving your own seeds from the crops you grow. Happy Gardening!!!

Record numbers of people are gardening this spring and victory gardens are rapidly sprouting across the nation. Now is a better time than ever to learn how to save seeds.
Some vegetables, like beans and peas, are self-pollinating. These are less likely to cross with other related varieties through insect pollination. Self-pollinating varieties are excellent choices for the beginning seed saver, as some pods can simply be left on the vine to dry out. Once completely dried, remove seeds from pods, place them in envelopes labeled with the variety and date and store them in an airtight container in a dry dark place. A mason jar placed in the refrigerator or freezer makes a good receptacle for seed packets. Properly stored bean and pea seeds should remain viable for three years.
Peppers cross easily due to pollination. You may notice your sweet bell peppers suddenly take on a spicy hot pepper quality if you don't separate pepper varieties by at least 100 feet or plant barrier crops in between varieties. But pepper seeds are some of the easiest to save; just remove seeds from the fruit and dry them for two to three days on a plate or paper towel. Properly stored pepper seeds remain viable for up to two years.
Some vegetables require much more care to ensure that seeds do not carry mixed or unexpected character traits. While corn is an American staple in the garden and whole cobs are easily dried, wind pollination leads to easy crossing between different varieties. If you want to save corn seed, grow only one variety in a large patch (or in patches of different varieties separated by 1,000 feet, if you have that much space). Members of the squash family within the same species readily cross and must be separated by a half mile or hand-pollinated to ensure a pure strain. Similarly, cole crops are all varieties of a single species, Brassica oleracea. Cauliflower, broccoli, Brussels sprouts, kale, cabbage, turnips, collard and bok choy will all cross with one another; therefore, growing only one variety at a time is recommended if you plan to save the seed.

A Daily Practice
A Precious Gift
Two years ago, we received 10 fava beans from our dear friends. The seeds originated from the Sacred Valley region of Peru where they were hand-selected for a distinct spiral pattern on the seed coat. Starting with just a few seeds, we decided to grow this plant out in our urban garden in Midtown Santa Cruz. After successful plantings, I gently gathered these the dried pods of the newly formed fava beans.
Selecting Seed Adapted to Our Bioregion
The spicy mustard greens that generously fed us over the late winter and spring season have also since gone to seed. I harvested the seed heads and set them to dry on a large repurposed bed sheet. When fully dry, I will gently stomp on these seedpods, and sift them through fine screens to separate the seed from the chaff. The plants that did particularly well in our bioregion are the ones that we save. Over time, seed that is hand-selected in a place can become well adapted to the environmental conditions of that specific location. There are many features to save seed for, including taste, size, texture, color, drought resistance, disease resistance and overall health.
How I Save my Seeds
When dry and ready, you can begin storing your seed. Seed is well kept in a glass jar. Be sure to label each jar with the name of the plant, the date in which you collected the seed, and the location the seed was collected from. Keep in mind that seeds are living! It is best to store your seeds in a cool, dry, dark/shady space away from sunlight.
