This classic heirloom onion is prized for its exceptional size, beautiful golden-straw skin, and deliciously mild, sweet white flesh. Perfect for fresh slicing, salads, sandwiches, and everyday cooking, Ailsa Craig is a favourite among gardeners who appreciate large, flavourful homegrown onions.\u003c\/p\u003e\n\n\u003cp\u003eThese productive plants develop substantial, rounded bulbs when provided with a long growing season and favourable conditions. Start seeds indoors during late winter to give plants a strong head start before transplanting outdoors in spring. Well suited to Canada's long summer daylight hours, Ailsa Craig is a rewarding choice for gardeners looking to grow impressive, sweet onions from seed.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Grow Ailsa Craig Onions?\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eImpressive, large, globe-shaped bulbs with beautiful golden-straw skin\u003c\/li\u003e\n  \u003cli\u003eDeliciously mild, sweet flavour ideal for fresh slicing\u003c\/li\u003e\n  \u003cli\u003eProductive plants capable of developing exceptionally large bulbs\u003c\/li\u003e\n  \u003cli\u003eClassic open-pollinated heirloom onion variety\u003c\/li\u003e\n  \u003cli\u003eLong-day variety well suited to many Canadian growing regions\u003c\/li\u003e\n  \u003cli\u003eApproximately 100–110 days to maturity from transplanting\u003c\/li\u003e\n  \u003cli\u003eGrows best in full sun\u003c\/li\u003e\n  \u003cli\u003eApproximately 120–130 seeds per packet\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to Grow Ailsa Craig Onions from Seed\u003c\/h2\u003e\n\n\u003cp\u003eStart onion seeds indoors approximately 10–12 weeks before your last expected spring frost. Sow seeds in flats or trays filled with a well-draining seed-starting mix, covering them lightly with approximately 6 mm (¼ inch) of soil.\u003c\/p\u003e\n\n\u003cp\u003eKeep the growing mix consistently moist during germination. Once seedlings emerge, provide 14–16 hours of bright light daily to encourage healthy growth. Onion seedlings naturally develop long, slender leaves, so occasional bending is normal. Trimming is generally unnecessary; focus on providing adequate light, moisture, and airflow.\u003c\/p\u003e\n\n\u003cp\u003eGradually harden off seedlings over 7–10 days before transplanting outdoors in early spring, once the soil can be worked and conditions are suitable. Choose a location with full sun and fertile, well-drained soil. Space plants approximately 10–15 cm (4–6 inches) apart, setting them at approximately their original growing depth without burying the developing bulb area too deeply.\u003c\/p\u003e\n\n\u003cp\u003eWater consistently throughout active growth and bulb development, keeping the soil evenly moist without waterlogging. As bulbs approach maturity and the tops begin naturally yellowing and falling over, reduce watering to encourage proper maturation and curing.\u003c\/p\u003e\n\n\u003ch2\u003eGrowing Onions in Canada\u003c\/h2\u003e\n\n\u003cp\u003eAilsa Craig onions are well suited to Canadian gardens when started early indoors. As a long-day onion variety, Ailsa Craig benefits from Canada's extended summer daylight hours, which encourage bulb formation after the plants have developed healthy foliage.\u003c\/p\u003e\n\n\u003cp\u003eFor the largest possible bulbs, provide fertile soil, consistent moisture, sufficient spacing, and a weed-free growing area. Onions have relatively shallow root systems and compete poorly with weeds for water and nutrients.\u003c\/p\u003e\n\n\u003cp\u003eAilsa Craig is primarily valued as a large, mild, sweet onion for fresh use. Unlike varieties specifically bred for long-term winter storage, its high-moisture bulbs are best enjoyed relatively soon after harvest.\u003c\/p\u003e\n\n\u003cp\u003eFor detailed instructions covering seed starting, spacing, watering, fertilizing, harvesting, curing, and pest management, read our \u003cstrong\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1105\/1214\/files\/How_to_Grow_Onions_-_Complete_Growing_Guide.pdf?v=1791519335\" title=\"How to Grow Onions in Canada | Complete Growing Guide\" target=\"_blank\" rel=\"noopener\"\u003eHow to Grow Onions in Canada | Complete Growing Guide\u003c\/a\u003e\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eAilsa Craig Onion Growing Information\u003c\/h2\u003e\n\n\u003ctable style=\"width: 100%;
