What Most Folks Get Wrong About Saving Seed (and Which Crops Cross)

Saving your own seed is one of the great economies and pleasures of gardening, but the whole thing turns on one distinction that catches almost every beginner: which crops breed true and which cross behind your back. Out here in the Willamette Valley our dry late summers make seed dry down clean, so this is the season to do it — but only if you save from the right crops. Beans, peas, tomatoes, peppers, and lettuce are self-pollinating: the flower pollinates itself before it even opens, so the seed comes up true to the parent. The brassicas — kale, broccoli, Brussels sprouts, cabbage, collards, mustard — are mostly the same species, insect-pollinated, and they cross readily, so the seed you save from them is a genetic surprise. In this one I show you how to tell the difference and how to harvest, dry, and store seed that's alive and true next spring. The single biggest seed-saving mistake — and I made it myself with a horticulture degree on the wall — is saving seed from an F1 hybrid and expecting it to come true. It won't. We cover open-pollinated versus hybrid, self-pollinated versus insect-pollinated, how to select and rogue for the best parents, the harvest cues (let pods dry on the plant, harvest lettuce when the seed coat is hard and dark, ferment your tomato seed), how to dry and winnow seed clean, and how to store it in sealed glass in a cool dark place with a desiccant and a label. If you've searched for how to save seeds, saving vegetable seeds, seed saving for beginners, do hybrid seeds come true, saving tomato seeds, saving bean seeds, or how to store saved seeds, this is the video for you. WHAT YOU'LL LEARN The difference between self-pollinated crops (breed true) and insect-pollinated crops (cross readily) The five easiest breed-true crops for beginners: beans, peas, tomatoes, peppers, lettuce Why you must save from open-pollinated varieties, not F1 hybrids Why the brassicas are mostly the same species and cross with each other How to select your best plants as parents and rogue out the off-types Harvest cues: dry pods on the plant, lettuce seed coat hard and dark, fermenting tomato seed How to dry seed crisp and winnow off the chaff before storage How to store seed in sealed glass, cool and dark, with a silica or powdered-milk desiccant Why you label every jar with the crop and the date, and how long different seeds keep SOURCES Oregon State University Extension Service — A step-by-step guide to saving seeds https://extension.oregonstate.edu/gar...

CONNECT Do you save your own seed, and what is the one variety you would never want to lose, the one you save every single year? Drop a comment and tell me where you garden — your state, your county, even just "outside Eugene" or "up Bellingham way" — because seed dries down clean in our dry Valley late summer, and it's a different proposition in a humid climate where you fight mold all through the harvest. I read every comment that comes through.
