Winter Gardening Tips: Expert Advice on Storing Potatoes and Testing Seeds for Spring Success

Gardeners eager for spring can keep busy during winter by tackling a few essential tasks, according to Kansas State University horticulture expert Cynthia Domenghini.

One priority is checking potato storage conditions. Potatoes store best in a cool garage or basement with 90% relative humidity and temperatures between 40-45°F. While temperatures below 40°F extend storage time, they can cause starches to convert to sugars, altering the flavor. To restore the taste, potatoes should sit at room temperature for 2-3 days before use. Prolonged exposure to temperatures above 45°F can cause sprouting, while low humidity can make potatoes soft and shriveled. Using perforated plastic bags helps maintain optimal humidity.

Winter is also an ideal time to test the viability of old garden seeds for spring planting. Most seeds remain usable for about three years when stored in cool, dark, and dry conditions. However, some seeds, like those from the carrot family, including carrots, parsnips, and parsley, have a shorter lifespan of just 1-2 years. Preparing now ensures a successful start to the gardening season.
