Growing Broccoli

Romanesco Broccoli.
Latest Update 27th August 2017.

Broccoli (Calabrese)
  • Waltham broccoli produces a firm tasty head followed by smaller floret side shoots extending harvest beyond a month, and Romanesco broccoli produces a large spiraling cone shaped lime green head.
  • Broccoli is a healthy vegetable containing lots of dietary fibre, minerals and vitamins.
  • We don't grow many in our garden as its a seasonal vegetable and occupies a lot of limited Ecobed space.  Normally I would grow just 2 Waltham and 2 Romanesco each year.
  • I have frozen surplus broccoli in the past, but we prefer it fresh and steamed for 10 minutes with a nice dressing of a herb and vegetable based sauce.

Maintaining Ecobed Productivity. 

  • Check out my blogpage which explains how I maintain productivity in my Ecobeds.  It describes how soil is prepared prior to planting, the importance of rainwater in Ecobeds, how to regulate the sun's intensity and how to feed plants through their leaves.
Propagating Seedlings. 

  • Check out my blogpage which explains how I propagate seeds.

Growing Instructions.
  • Sow Broccoli seeds an EcoPropagator and when the seedlings are big enough, plant them in their jiffy pots into the prepared bed at 750mm centres along rows 500mm apart.
  • Expose a small area of soil by pushing the mulch out of the way and burying the pots deeply covering most of the plant's stem to maximise its stability in high winds.
  • Water in generously and return the mulch so that all the soil is covered.
Harvesting and Storage.
  • Harvest broccoli from June onwards.
  • Waltham broccoli produces a large firm head, which should be harvested before it starts to flower.
  • Allow the broccoli to continue growing and it will reward you with a succession of edible side shoots.  Harvest them regularly before they flower and they will continue to produce for several months in a warm temperate climate.
