Basic information about broccoli

  • Crop group: cabbage crop.
  • Crop family: Cruciferous family.
  • Height: approximately 45–75 cm.
  • Root system: 45–90 cm deep.
  • Frost resistance: not really frost hardy; light cold is possible, but avoid prolonged or severe frost.
  • Preferred soil: Well-drained, nutritious soil with pH 6.2–7.2.
  • Fertilization: start with a nitrogen-rich fertilizer (e.g. nettle manure, cow manure), then switch to potassium-rich foods such as comfrey manure. Too much nitrogen produces lots of leaves and few flowers.

Introduction

(Full Latin name: Brassica oleracea var. italica)


Broccoli is a nutritious vegetable that can be used in a variety of ways. You can eat it fresh, lightly sauté it, or use it in stir-fries, soups, pasta, or rice dishes. If you follow a few simple broccoli growing tips, growing your own broccoli isn't difficult at all. Read all the tips about growing broccoli, from sowing to harvesting, here :)

Broccoli is a green vegetable that vaguely resembles a miniature tree. It is closely related to cabbage, Brussels sprouts, kale, and cauliflower—all edible plants belonging to the cruciferous family. Broccoli differs from other brassicas in that it is primarily grown for its flower buds, while other brassicas, such as cauliflower, Brussels sprouts, and kohlrabi, have other edible parts. The compatibility and differences between broccoli and other brassicas are important when planning crops, for example, for cross-pollination and optimal growing conditions.


There are three main varieties of broccoli:


  • Calabrian broccoli
  • Sprouting broccoli
  • Purple cauliflower - despite its name, a type of broccoli

My name is Tom and I am co-owner of Plukkers.com. I am the father of two beautiful daughters and I have a wonderful wife. When I turned a bare spot in the lawn into a herb garden in 2014, I got a very special feeling inside. I immediately felt that it was not a whim but the start of an irresistible and fiery passion. I wanted to know everything and also wrote down what I learned on my website Moestuinweetjes, which is now called Plukkers.com. I also want to inspire other people to grow their own food. At my house in Wielsbeke is my dream garden with a greenhouse, vegetable garden and a hobby vineyard with 333 vines. In addition to wine, I also make delicious beer at home to occasionally celebrate life in moderation. I toast with you to an exciting, richly filled life under the motto: "Make it yourself!"
