More and more, customers are asking us to carry Organic Seed Potatoes at Mary's Heirloom Seeds. You might be asking yourself, "What's the difference between a Seed Potato and one I can get from the grocery store and sprout?"
First, Seed Potatoes are typically specific strains (varieties) of potatoes and are disease free. If you know about the Potato famine in Ireland or have experience blight or other plant diseases then you can appreciate disease free seeds.
Also, some store bought potatoes are sprayed/dipped/treated so that they won't sprout or "grow eyes."
Harvest dates will vary based on variety of potato. Generally, potatoes take 90-120 days to harvest.
- Under optimal conditions, you can expect to harvest 10–15 pounds of potatoes for every pound of seed potato planted.
Potatoes are not roots but specialized underground storage stems called “tubers.” Potatoes can be planted anytime the soil temperature is above 45 degrees and there is no danger of a hard freeze at least two weeks after planting. Maximum tuber formation occurs at soil temperatures between 60 and 70 degrees F.
This is a basic guide. Planting Potatoes should occur 2-3 weeks BEFORE your last frost date.
We are currently offering PRE-ORDERS of select varieties of
ORGANIC *Non-GMO* SEED POTATOES Depending on your location AND date of purchase, seed potatoes will be available to ship as early as January 1. *Price and availability subject to change*
