In this article, we zero in on what goes wrong when your broccoli forms loose, bitter heads, and how to prevent this from happening.
Let’s start with a brief overview of the conditions necessary for successful cultivation.
Optimal Growing Conditions
This cruciferous veggie, that I often call a prima donna, needs the following conditions to thrive:
A full-sun location Organically-rich soil, with a neutral pH Spacing as per seed packet instructions Even moisture and excellent drainage Cool, even temperatures Time to fully mature in cool weather Adequate pest and disease control
These conditions are crucial. You can review the full details of each in our article about the essentials of broccoli head formation.
Let’s find out why heads are sometimes not as tight and sweet as we would like.
The Triggers of Trouble
When broccoli forms loose, separate florets, rather than a solid head, look to the essential growing conditions for answers.
Problems in four main areas are most likely to cause this type of head malformation. They are: nutrient imbalances, warm or fluctuating temperatures, uneven moisture, and poorly timed planting.
Each one by itself may have an adverse effect, and when all four occur, chances of a disappointing result are even greater.
