Mrs. Darling asked this question and I thought more of your advid gardeners would like to know this as well.
Mrs. Darling asked if we grow it in the open sun. She goes on to say that the only information she can find about says it is a cool weather crop and if grown in the summer you must make sure the soil stays cool. She would like more info on how we grow this crop.
Well, we grow all of our veggies except okra on raised beds, covered with plastic and irrigated underneath. The plants are watered daily, sometimes more. They get little water other than the irrigation. The foliage gets it's water from the rain. Their primary source is from irrigation (drip tape placed underneath each row.
All of the broccoli is usually harvested by the 10th or 15th of June. We have been picking it for a couple of weeks or so here. It has a very short growing season due to the heat. We had 92* weather here today and that is not good for cool weather crops (such as cauliflower, broccoli, Bok Choy, etc.), no matter how wet and cool the soil.
The picture above shows how the rows are laid out......I wish I had a better picture but I don't.
I hope this helps. Please feel free to ask any other questions. Blessings!!!
