Ah, the humble onion. Harvested and grown for centuries as a staple food, the onion has layers of history in cuisines around the world. While you can plant onions from transplants or sets, growing onions from seed offers the most cultivars and disease resistance. Mountain Valley Seeds carries a myriad of different varieties, ranging from bulb to bunching types. For beginners, bunching onions such as the Tokyo Long White or the Evergreen can be a good place to start. However, that is not to say that bulb onions are rocket science. Just make sure to select short day or long day varieties for the day length of your area. Long day varieties such as South Port Red Globe are great for Northern regions with long daylight during the summer. White Grano and Red burgundy shine as short day varieties in regions with mild winters and consistent daylight hours, while Walla Walla and Candy onions thrive in any region. Onion Seeds available up to bulk quantity at wholesale.

Onions are used in dishes for every meal of the day. No wonder so many gardeners have a few in their gardens. To choose which onion variety to plant depends on what you want to do with them and what climate you live in. If you are growing them for green onions choose a bunching onion like Tokyo Long white, or if you want to pickle them use Crystal white wax, the larger bulbed varieties are used for slicing. Short day onions such as Red Burgundy are more suited to Southern states where they are typically grown in the winter months. Long day onions such as Walla Walla are more suited to northern states where they are grown in the summer months.

Onions can be direct seeded in the early spring months or started a few months before the last frost date inside. A warm soil encourages faster germination so using a seedling heat mat is helpful. Onions are heavy feeders so amending the soil previous to planting and side dressing is helpful. Plant outside a few weeks before last frost . They can be planted in double rows 8 inches apart to conserve space. Onions will grow on top of the soil with only the very bottom and the roots in the soil.
