Romanesco Broccoli Seeds For Planting (Brassica oleracea)

Sowing The Seed

Romanesco Broccoli is a cool weather crop that can be started indoors, or directly outdoors. If started indoors, sow in starter pots, 4 to 6 weeks prior to the last frost. If started outdoors in the Spring, sow just before the last frost, or in mid-summer, for a fall harvest. Till your sowing area, removing all unwanted plant life and weeds. Sow the seeds at a depth of 1/4” under, in rows measured about 10’ long.

Growing Conditions

Broccoli will grow in an area that receives full sunlight for at least 6 hours daily. The plants will bolt and go to seed if temperatures are too high. the soil should be fertile and rich in organic matter, but also well drained. To improve drainage, we recommend adding a light compost to areas containing hard, compact soil. Water daily to ensure that the seeds receive enough moisture to germinate properly.

Germination & Growth

Broccoli seeds typically germinate within 7 to 14 days after sowing. The plants will grow 2 to 3 feet tall, spreading about 12 inches wide. They can be spaced 18 to 24 inches apart from one another, in rows spaced 24 inches apart. Romanesco will produce 5 to 6 inch, spiraled, lime green heads that boast a better flavoring than most finer Broccoli’s available. They are ready for harvesting in roughly 75 to 100 days.

Harvesting Romanesco Broccoli

Romanesco Broccoli will be ready for harvesting in roughly 100 days. Cut the head from the base and store in the fridge or in a cool part of the home. You can save the florets by freezing as well.
