Harvest & Use

Harvest when tops begin to fall over and turn brown, typically in late spring to early summer. Pull bulbs and cure in a warm, dry, well-ventilated area for 2-3 weeks until outer skins are papery. Texas 1015 onions are famous for their exceptional sweetness and mild flavor – perfect for slicing raw on burgers and sandwiches, grilling whole, caramelizing, or showcasing in onion rings. These sweet onions have higher water content, so they're best used fresh or stored for shorter periods (2-3 months).

Care Tips

Short-day onions require 10-12 hours of daylight to form bulbs, making them ideal for southern gardens. Plant in well-drained, fertile soil enriched with compost. Water consistently – these onions need about 1 inch of water per week for optimal sweetness and size. Side-dress with nitrogen fertilizer when plants reach 6-8 inches tall. Keep beds weed-free. Companion plant with carrots, lettuce, or beets for efficient garden space use.
