If there is enough seed for several years, then take further steps to ensure viability.<\/p>\n\n\n\n<p>A 10-year storage life can be achieved by drying seed to less than 8 percent moisture. To do so, dry seed at 100 degrees F for six hours. Obtain this temperature by spreading the seed out in direct sunlight. However, because sunlight is harsh and easily can exceed this temperature, drying in the shade is better.<\/p>\n\n\n\n<p>Never use a microwave oven. You may use a conventional oven if you keep the door open and the seed is not heated to more than 100 degrees. Package the seed in moisture-proof containers and store it in a refrigerator or deep freezer. A moisture-proof container is one that stores seed safely while submerged in water. Use sealed cans or jars, rather than plastic bags.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">SMB Regional Seed Library Information<\/h3>\n\n\n\n<p><strong>The SMB Regional Seed Library is restocked at the Norwood and Naturita Libraries!\u00a0<\/strong><\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a tabindex=\"0\" class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/extension.colostate.edu\/san-miguel\/offering\/san-miguel-basin-regional-seed-library\/\">Learn More<\/a><\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>A garden\u2019s success depends in part on the quality of seeds planted.
