Our annual vegetable, herb, and flower seeds can be grown almost anywhere in the world, you just have to plant them at the right time of year for your climate. Cool season crops are planted in spring and fall, while warm season crops are grown in summer. Gardeners in the northern tier have shorter seasons and may need to select early maturing or frost-tolerant varieties. Gardeners in the south have longer, more flexible planting windows and may want to look for heat-tolerant varieties. These are noted in the variety descriptions.
To plan your garden, the most important piece of information you need to know is your last spring frost date and first fall frost date. Ask an experienced gardener in your neighborhood, or inquire at a local plant nursery. You can also contact your local Cooperative Extension office. Our “Grow Guides” for each crop provide detailed information on when to plant based on your frost dates.
