How to Grow Broccoli in Biggsville, Illinois, United States of America

About broccoli: Broccoli is said to have originated in the Mediterranean, where it still grows wild today along the Mediterranean coast. Broccoli has been cultivated for thousands of years, and believed to have specifically originated in Italy in ancient Roman times. 

Broccoli is a member of the cabbage family, much like cauliflower, bok choy, garden cress, brussels sprouts and kale. The name "broccoli" comes from the Latin word brachium, meaning "branch" or "arm". The seeds which started the U.S. broccoli industry came from Messina, Italy, brought to the US by two Italian immigrant brothers, Stefano and Andrea D'Arrigo, and were planted in 1923 near San Jose, California. Today, broccoli is grown in nearly every state, including Alaska and Hawaii. 

U.S. per capita fresh broccoli consumption has increased over the last two decades with per capita consumption of fresh broccoli increasing to 4.5 pounds – consumption of fresh broccoli has quadrupled in North America since 1980. Unlike previous generations broccoli is no longer “taboo” with children in US households, in fact, quite the opposite. Broccoli is popular in US gardens despite its relative difficulty in growing and the space that it consumes in the garden. T

The broccoli is a cool-weather crop, thriving in moderate to cool climates, and does poorly in very hot climates. It is mostly grown from seed, directly sown in the ground. Broccoli is rich in calories, vitamin K and C. It also has manganese, and low carbohydrates, fat, proteins and dietary fibers' content.

Broccoli Germination Guide

(Stage 1: Germination)

Germination is the process by which a plant grows from a seed. It is the first stage of the plant growing process and it begins when the seed is sown and ends when the radicale emerges out of the seed.

All seeds require proper soil temperature, moisture, air and light conditions to germinate successfully. However, during the germination stage the seeds require more soil warmth and moisture than light exposure.

Seeds respire just like any other living organism, requiring oxygen and producing carbon dioxide (CO2), so it is crucial to use a soil media that is sufficiently aerated so that the seeds do not “suffocate”.

100% of our growing experts recommend to directly sow broccoli seeds into the ground. What is direct sowing and why do I care about it?

Broccoli Growing Guide

(Stages 2-5: Growth)

Once seed has germinated and radicale has emerged the second stage of the plant growing process begins, developing from radicale to cotyledon -the embryonic first leaves of the seed forming a young seedling.

During the third stage of plant development cotyledon develops to 3-4 true leaves, stem begins to grow, becoming a mature seedling.

In the fourth stage the mature seedling develops to a young plant, ready for transplanting.

The fifth stage of plant development the plant is fully mature bearing fruit and/or flower.

The following guidelines apply to all of the broccoli plants’ needs during stages 2-5 from radicale emergence to full maturity. During these stages sunlight becomes a more active participant in plant growth and development than in the germination phase.

Soil pH is an important factor during these stages as well. What is pH and why is it important?

How difficult is it to grow broccoli?

Growing broccoli, or any other vegetable for that matter, is not hard, however some plants require more attention and care than others depending on the following factors:

 

Are you starting to grow your plant from seed? seedling? young plant? Depending on what stage plant you choose to plant will impact growing difficulty and patience.

The length of the growing season for your exact garden location.

Whether you direct sow in the garden or start in trays and then transplant also affects the level of difficulty

Growing difficulty level - 0

Growing patience level - 0
