The best thing about cauliflower seeds is just how much usable veg you can get from directly sowing in your garden. Cauliflowers can grow to huge sizes, and larger heads mean thicker, firmer florets that are perfect for roasting, steaming, or adding to your favourite meals. Learning how to grow cauliflower from seed means you can use homegrown vegetables from your garden that are packed with vitamins and minerals and taste better than supermarket produce.
When to Sow Cauliflower Seeds
For the best results, sow your cauliflower seeds just as summer turns to autumn, giving them as much cool weather as possible to germinate in. They need plenty of time to mature, so sowing at this time gives you the optimal time to grow fresh, homegrown cauliflower for when the weather cools down. Cauliflower can be grown all year round, but the summer sun encourages more foliage growth and smaller heads.
How Long to Grow Cauliflower From Seed
Cauliflower seeds take between 12 and 16 weeks to mature from seed. To ensure healthy growth that sticks to this timeline, sow your cauliflower seeds 5mm deep in seed trays or small pots, using a quality seed-raising mix. Keep them in a warm spot and make sure they’re well-watered but not soggy.
After about six weeks, harden them off and transplant them into a sunny, well-drained spot in your garden. Cauliflower seedlings love a nutrient-dense environment, so enrich the soil with compost. Warm weather can cause them to bolt or deform, so keep them in a cool place in the garden.
