Cauliflower Seeds FAQs

Here are some frequently asked questions from customers looking to buy Cauliflower Seeds in the UK. For more information, feel free to contact our Customer Service Team or browse our general FAQs.

When to plant Cauliflower Seeds
Cauliflower seeds should be started indoors in early spring (February to March) for an early summer harvest or in late summer (July to August) for a late autumn harvest. Sow the seeds 6-8 weeks before the last expected frost date. Once the seedlings are strong enough and the outdoor conditions are suitable, transplant them outside after the danger of frost has passed, usually in late spring or early autumn.

How to Plant Cauliflower Seeds


Sow cauliflower seeds in seed trays or small pots filled with seed compost, about 1-2 cm deep. Keep the trays in a warm, bright location at a temperature of around 18°C. Ensure the compost stays moist but not waterlogged. When the seedlings have developed a few leaves and the outdoor temperatures are warm enough, transplant them into the garden or raised beds, spacing the plants about 45-60 cm apart. Ensure the soil is fertile and well-drained, and keep the plants consistently watered.

How long do Cauliflower Seeds take to grow?


Cauliflower seeds typically germinate in 7-10 days under warm conditions. After transplanting outdoors, you can expect the plants to mature in about 12-16 weeks, depending on the variety and growing conditions. Cauliflower is a cool-season crop, and the heads are usually ready to harvest in mid to late summer or early autumn, depending on when you planted the seeds.

Why should I plant Cauliflower Seeds?


Cauliflower is a nutritious, versatile vegetable, rich in vitamins and fiber, and can be used in a variety of dishes, from roasts to stir-fries. Growing cauliflower from seed ensures a fresh supply of this delicious vegetable, and there are many varieties to choose from, including early, mid, and late-season types. If you enjoy growing your own vegetables, cauliflower can be a rewarding crop, although it does require some attention and care.

Where can I plant Cauliflower Seeds?


Cauliflower grows best in well-drained, fertile soil in a sunny location. It thrives in cooler temperatures, making it perfect for early spring or late summer planting. If planting outdoors, space the plants about 45-60 cm apart to allow for proper air circulation. Cauliflower also benefits from a good amount of water, so ensure the soil remains moist throughout the growing season. Raised beds, traditional garden plots, or even large containers work well for growing cauliflower.
