SEED QUALITY AND SEED SAVING Melanie Hernandez High Mowing

High Mowing Organic Seeds Who are we and how do we know all this stuff about seed saving and quality? We are producers and sellers of 100% certified organic hybrid and open-pollinated seeds Our 2014 Catalog will contain 700 varieties of organic seed

High Mowing Organic Seeds We breed and license exclusive varieties on our own farm and in collaboration with other universities We trial 1000 varieties/yr.

Our Amaizing Corn Organic hybrid sweet corn variety My Fair Lady F1 Hybrid

Breaking New Ground High Tunnel Seed Production in Vermont

WHAT DOES A SEED NEED TO SUCCEED? 1. Dry-seeded crops need dry weather around harvest to avoid fungal diseases (e.g. salad greens, radish) 2. Wet-seeded crops need only ample moisture, but often yield better with more heat (e.g. tomatoes, peppers, squash) 3. Certain crops need cool weather to MAKE seed (e.g. spinach, beets, chard, cole crops) 4. Certain crops need heat for seed to FINISH (e.g. beans and peas)

WHAT DO WE MEAN BY QUALITY SEED? Germinates at or above a defined minimum germination usually 80% for vegetable seed, 70% for flowers and herbs Germinates quickly with strong vigor and full set of seedling parts The higher the initial quality, the longer it will hold that quality

WHAT ENSURES GOOD SEED? Fully mature at harvest = finished Moved quickly from wet to dry during harvest processing Dried down to ~10% moisture or lower Not allowed to get too hot during drying Stored in cool, dry conditions

HOW DO I KNOW IF MY SEED WILL GERMINATE?

How do I know my seed is PURE? ISOLATION ISOLATION ISOLATION

WHICH CROPS REQUIRE ISOLATION? 1. Read seed catalogs or go online to determine the SPECIES of your crop 2. Figure out which species are INSECT or WIND pollinated (e.g. Squash, melon,crucifers, corn) These REQUIRE ISOLATION

WHICH CROPS DO NOT REQUIRE ISOLATION? All SELF-POLLINATED crops do NOT require isolation Tomatoes, lettuce, beans, peas

Resources to Consider: 1. Seed to Seed by Suzanne Ashworth (for isolation requirements and seed specifications) 2. The Garden Seed Inventory by the Seed Savers Exchange (for finding varieties) 3. On-Line www.howtosaveseeds.com

SAVING YOUR SEED: SQUASHES/CUCUMBERS/MELONS SQUASHES, CUCUMBERS: - easy to grow for seed - need ISOLATION of ~1 mile MELONS, WATERMELONS: - often require plastic and row cover to get enough heat - need ISOLATION of ~1 mile

SQUASH/CUCUMBER MELON SEED HARVESTING I 1. Select your best fruit to harvest nothing rotten 2. Harvest squash/cucumber/melon seed by first cutting fruit and scooping out seed

SQUASH/CUCUMBER MELON SEED HARVESTING II WASH seed in a strainer or by fermentation and rinsing make sure to pick out flesh and get it very clean

SQUASH/CUCUMBER MELON SEED HARVESTING III DRY seed flat on a paper towel or screen -- make sure it s dry enough to snap in half when you bend it

SAVING YOUR SEED: TOMATOES/PEPPERS/EGGPLANT TOMATOES: - easy to grow for seed - NO ISOLATION required (or just 50 ft) PEPPERS/EGGPLANT: - often require plastic and row cover to get enough heat - need isolation of ~500 feet

TOMATO SEED HARVESTING I 1. Select your best fruit to harvest nothing rotten 2. Harvest tomato seed by crushing fruit and allowing to ferment for 24-48 hours Fermentation is needed for tomato seeds (in order to remove a germination-inhibiting gel),

FERMENTING TOMATO SEED

TOMATO SEED HARVESTING II WASH seed after fermentation by rinsing to remove all flesh

RINSING TOMATO SEED

TOMATO SEED HARVESTING III DRY seed after rinsing by spreading on a towel or screen

DRYING TOMATO SEED

SAVING YOUR SEED: Beans and Corn BEANS DRY BEANS work well GARDEN BEANS and PEAS can work, but are prone to disease due to sugar in the pods Edible soybeans (EDAMAME) can work, but are difficult due to long season for maturity CORN - FLINT CORN works well - SWEET CORN can do well, but more prone to mold have to be harvested before dry

SEED STORAGE DRY + COOL GOALS = 1.keep seed from molding 2.keep seed alive as long as possible

SEED STORAGE SEALED jars, ziploc bags, or bins (For DRY seed) If any doubt, use PAPER envelopes or bags (to avoid mold)
