1. Understand how to grow I'itoi Onions
I’itoi onions are a multiplier onion (allium cepa var. Aggregatum). The onions do not produce seeds but are grown from bulbs planted in the ground. The planted bulb multiplies and is propagated by division of bulbs. This easy-to-grow onion rarely (if ever) sends up flower stalks and bolts. I’itoi onions tolerate and even thrive in the Sonoran Desert’s difficult growing conditions. One bulb becomes 8 or 10 bulbs, which in turn become more bulbs. You will be amazed how quickly these bulbs multiply.
2. Plant I’itoi onions correctly
In the low deserts of Arizona, plant I’itoi onions in the fall. Obtain bulbs from Native Seed Search or other growers. In cooler areas, plant I’itoi onions in the spring. Plant each bulb about an inch deep, 8-12 inches apart. I’itoi onions tolerate native soil well and do not require additional feeding. However, richer soil will produce larger bulbs and shoots. I’itoi onions also tolerate dry conditions and will respond to monsoons and other rains with growth. Just as with amendments to the soil, regular watering produces larger bulbs and shoots.
3. Plant I’itoi onions as companion plants
Because I’itoi onions are easy to grow, it is simple to plant them throughout the garden. Onions are excellent companion plants for brassicas, beets, strawberries and tomatoes. Simply plant one bulb near the plant and the I’itoi onions will grow and divide, and provide the benefits of companion planting. Do not plant near peas and beans as plants in the onion family may impede their growth. For more information on preventing pests organically, read this post.
4. Use all parts of the I’itoi onion
As green shoots develop, they can be harvested and used like chives in recipes. The greens have a mild flavor and work well in most recipes that call for chives. You can also harvest bulbs as needed throughout the growing season. To use bulb, wash well and peel back skin to remove it. The bulbs have a mild peppery flavor similar to shallots. They are delicious sautéed and in recipes that call for shallots or onions.
5. Gather and share your harvest
When the greens die down, the bulbs are ready to harvest and divide. Pull up clumps of onions and allow to cure in a shady dry location for several days. Remove dried up shoots and divide onions. Store in a cool dry location.
Pinch yourself when you realize that your few planted bulbs multiplied many, many times! Each time you harvest I’itoi onions, save some to plant and share some with others. Teach others how to grow I’itoi onions, and share what you’ve learned!
