        100 Seeds Pack    

The Red Onion of Amposta, also known as Morada de Amposta, Bronze D'Amposta, or Bronze of Amposta, is a large, sweet onion variety originating from the small Spanish town of Amposta. With its reddish to copper-toned skin, this heritage onion produces attractive red-bronze bulbs. Its dense, juicy interior is marked by distinct red and white rings, offering a pleasant, exceptionally sweet flavour. Semi-early in nature, it is best sown in early spring and matures around 115 days after planting. These beautiful, large globes typically weigh between 200 to 250 grams.

    PLANTING & GROWING

Soaking needs to be done at least a few hours before planting, and preferably overnight. To prevent damping off when starting seeds indoors, it’s essential that you disinfect all of your pots, plastic grow trays, seed cells, and seedling tray covers before you reuse them. 

Sow onion seeds under cloches in February or directly outdoors from March to April, with harvest typically occurring 24 weeks later. In colder climates or for exhibition bulbs, start sowing indoors under glass in January, harden off in March, and transplant outdoors in April.

Sow seeds thinly in 1.2 cm (½ inch) deep drills, leaving 25 to 30 cm (10 to 12 inches) between rows. Thin spring-sown seedlings first to 2.5 cm (1 inch), then once they have straightened up, space them 5 to 10 cm (2 to 4 inches) apart. Autumn-sown seedlings should be thinned to 2.5 cm (1 inch) in the fall, with further thinning to 5 to 10 cm (2 to 4 inches) in spring. Seedlings raised under glass should be transplanted 10 cm (4 inches) apart, leaving 23 cm (9 inches) between rows. Ensure the roots fall vertically into the planting hole, with the bulb base about 1 cm (½ inch) below the surface.

Onions are insect-pollinated and require a 1–3 mile isolation distance from other onion varieties to prevent cross-pollination.

Onions are excellent companion plants, as they repel pests like cabbage worms, cabbage loopers, Japanese beetles, and cabbage maggots. They also benefit brassicas such as broccoli, kale, cauliflower, turnips, kohlrabi, and Brussels sprouts when planted nearby. However, avoid planting onions next to peas, beans, sage, or asparagus.

It's crucial to not plant onions in the same location for more than three consecutive years.
