Harvest
Cauliflower ‘Jerome’ F1 is a top-performing hybrid variety, producing strong, uniform plants with impressive curds. Ready for harvest from March to April, it ensures a rewarding supply of fresh, homegrown cauliflowers when little else is cropping.
Recognised with the RHS Recommended: Award of Garden Merit, ‘Jerome’ is bred for reliability and quality, standing well through variable winter weather. Its protective leaf growth can also be folded over the curds to shield them from the elements, keeping the heads pristine and white.
With its vigour, resilience, and excellent flavour, ‘Jerome’ F1 is a superb choice for gardeners looking for a reliable winter-to-spring cauliflower variety.
How To Grow
Cauliflowers are a rewarding vegetable to grow, producing versatile heads that are delicious roasted, steamed, or added to soups. They thrive in nutrient-rich, well-drained soil with consistent moisture and firm ground to stop plants rocking in the wind, which can cause bolting and poor head formation. Start seeds indoors for strong early growth, then transplant into sunny spots with space for heads to develop. Protect young plants from slugs, caterpillars, and other pests.
Indoor Sowing Fill modular seed trays with fine seed compost and moisten before sowing. Place one seed per module to give space for roots to develop. Keep compost evenly moist using a gentle mist. Position trays in a warm, bright spot out of direct sunlight. Once Professional Grower Plugs develop true leaves or roots fill the modules, harden off before planting out.
Planting Out Harden Professional Grower Plugs over 7–14 days by gradually exposing them to outdoor conditions. Transplant into pots or directly into beds once acclimatised.
Outdoor Sowing Choose naturally disease-resistant varieties to avoid club root. Use brassica collars to deter root fly and netting to protect from insects and birds. Plant Professional Grower Plugs 1cm deep, spacing 45cm between plants and 45cm between rows.
