You can easily grow this plant with seeds.

  • Plant seeds 4-6 weeks before the last average frost date in your region.
  • Sow seeds in a well-draining potting mix.  
  • When the seedlings grow up to 3-4 inches, transplant them to the garden or continue to grow them in a container that’s at least 10-12 inches wide.
  • Put the pot in a location that enjoys bright but indirect sunlight in an area.

Location / Light

For best growth and size, locate the plant where it gets at least 3-5 hours of bright and direct sunlight every day. Growing it in a shaded location will result in small broccoli.

If you live in a warm climate, protect it from the long exposure to harsh afternoon sun. This will help the plant avoid bolting. 

Soil

Romanesco Broccoli loves rich, loamy soil full of organic matter with good drainage. It will grow the best between a pH range of 6.0-6.8. The plant also requires a bit of acidity.
Adding a bit of leaf mold into the growing medium will do wonders for soil texture. 

Water

This plant likes evenly and consistently moist soil, but it should not be wet or soggy. Also, it is best to water the veggie from the base and not overhead to prevent root rot.
Add a layer of mulch to help retain moisture in the soil. Also, never let the growing medium go dry completely.

Fertilizer

Add compost to the soil before transplanting to improve the drainage and nutrient content. Also, side-dress with aged manure during the mid-growth.

Using a balanced liquid fertilizer, diluted to 1/2 of its strength, once in 2-3 weeks will be good enough as well.

Pruning

Typically, pruning is not necessary for this vegetable, but you should regularly get rid of any diseased or damaged plant parts before they can cause any harm to the whole plant. 

Pests and Diseases

Romanesco broccoli is prone to pests that affect cauliflower and broccoli. Keep an eye on pests like cutworms, cabbage loopers, and cabbage worms. If you see them, use a strong jet of water to get rid of them, or try insecticidal soap or neem oil as these are organic solutions.
In diseases, be on a lookout for clubroot and downy mildew. Pick disease-resistant varieties and provide proper air circulation between plants.
