How to Grow Broccoli (Calabrese)

Calabrese require an open unshaded site with free draining but moisture retentive soil with plenty of organic matter.Nitrogen requirements are high so an addition of farmyard manure the previous Autumn is ideal.Like most brassicas Calabrese is best sown in a modular seedling tray as the plants don't like root disturbance.Cover the seeds with another layer of compost then scrape across the top of the tray with a stick to remove excess.You can make a makeshift light box by placing a sheet of reflective tinfoil on the room side of the seedlng tray.You do need to be careful, however, not to let the compost plug completely dry out or it will form a crust on top and won't absorb the moisture the next time you water.You can leave the cloche off the plants on dry frost free days and replace at night.Gradually increase the time with the cloche removed until the end of the week when you leave it off day and night.Wide spacing of 45cm in rows 60cm apart will produce very large heads to impress your neighbours while the more common spacing for medium sized heads is 40cm between plants in rows 40cm apart.To plant your seedling make a hole in the soil the approximate size of the seedling 'plug'.A light sprinkle of seaweed/poultry manure around the planting hole will help your calabrese get off to a good start.Recent transplants are most vulnerable and will die, when plants are lifted you will find small white maggots around the roots.Use cabbage collars fixed around the plant stems or cover the crop with protective mesh or fleece.To prevent butterflies laying eggs protect the plants a fine insect mesh.Leatherjackets and Cutworms are a similar grey/brown colour and live below the surface of the soil where the emerge from at night.Initially a central dome will form, after this is harvested the plant will produce numerous smaller side shoots.Watch our Calabrese Broccoli video with Andrew Davidson and professional organic grower Klaus Laitenberger.All our videos are filmed over a full season so you can see the sowing, planting, crop care and harvesting stages. .
