FAQs
When is the best time to sow 'Jerome' F1 cauliflower seeds?
For an early spring harvest (March-April), sow seeds in August. For an autumn harvest, sow from late spring to early summer (May-July).
How do I ensure the cauliflower heads stay white?
Once the curds start to form, carefully fold the large outer leaves over the developing head. This protects it from sunlight and frost, maintaining its pristine white color.
What is the significance of the RHS Award of Garden Merit?
This award signifies that the variety has been tested and proven to be outstanding for garden use, offering excellent performance, disease resistance, and quality.
Can I grow this variety in a container?
While possible, cauliflower prefers ample space for root development and leaf growth. For best results and head size, ground planting in well-prepared soil is recommended.
What kind of soil does 'Jerome' F1 need?
This variety thrives in fertile, well-drained soil rich in organic matter. Adding well-rotted compost or manure before planting is highly beneficial.
How much water does this cauliflower variety need?
Consistent moisture is crucial. Water regularly, especially during dry periods and when the curds are developing. Avoid waterlogged soil.
How many seeds are typically in a pack?
A pack contains approximately 30 seeds.
Troubleshooting
Seeds not germinating
Ensure seeds are fresh and stored correctly. Check that soil temperature is adequate for germination and that seeds are sown at the correct depth.
Plants are weak or stunted
Check soil fertility and consider adding compost or a balanced fertilizer. Ensure adequate sunlight and water.
Curds are small or discolored
Ensure consistent watering and adequate soil nutrients. Utilize the protective leaf-folding technique to maintain whiteness. Harvest promptly once curds reach desired size.
Pest infestation (e.g., aphids, caterpillars)
Inspect plants regularly. Remove pests manually, use insecticidal soap, or introduce beneficial insects. Netting can prevent egg-laying.
Plants bolting (flowering prematurely)
This is often caused by stress, such as sudden temperature changes or irregular watering. Ensure consistent conditions during growth.

Setup, Compatibility & Care
Sowing: Sow seeds indoors or in a seedbed from late spring to early summer (May to July) for an autumn or early spring harvest. For an early spring crop, sow in August. Transplant seedlings when they have 3-4 true leaves.
Location: Choose a sunny spot with well-drained, fertile soil. Brassicas benefit from crop rotation; avoid planting where other brassicas (cabbage, broccoli, kale) have grown in the last 2-3 years.
Soil Preparation: Dig in well-rotted compost or manure before planting to ensure good fertility and moisture retention.
Care: Water consistently, especially during dry spells and head formation. Mulching can help retain moisture and suppress weeds. Keep an eye out for common brassica pests like cabbage white butterflies and aphids. Consider using netting or organic pest control methods. As the curds begin to form, fold the protective leaves over them to maintain whiteness and protect from frost.
Compatibility: Generally compatible with most garden environments. As a brassica, companion planting with aromatic herbs like rosemary or thyme can help deter pests.
