Cartier Onion demands consistent, generous watering to develop properly formed bulbs, as onions are photoperiodic plants that regulate their growth stages through day length. The 2-inch plant spacing combined with 12-inch row spacing allows for efficient garden use while supporting healthy bulb development. Its 103-day timeline positions it as a solid mid-to-late season crop, giving gardeners flexibility in timing successive plantings.
As a bulbing onion, Cartier works in any kitchen application where storage onions are valued: raw in salads and salsas, caramelized for soups and French onion soup, roasted as a side dish, or cooked down into savory sauces and condiments. The variety's extended maturity suggests good keeping qualities typical of full-season bulbing onions.

Sow up to 10 to 12 seeds in a 4 to 6 inch pot. If seedling tops reach over 5 inches before transplanting, cut them back to 3 inches to strengthen the plants.
When transplanting, carefully separate the seedlings and place them in a shallow trench. Fill the trench around the seedlings and water in well.
Direct sow and thin to the strongest plant when seedlings reach 4 to 5 inches tall.
Cartier Onion is ready to harvest approximately 103 days after direct seeding. Begin monitoring when about half the tops have fallen over naturally; at that point, push over any remaining upright tops and wait roughly one week before pulling the bulbs. Harvest when the necks have dried and the outer papery skin has fully formed, which indicates the bulb is ready for curing and storage.
