Broccoli is a common dish served at dinner time among American households. Despite this, it can be difficult to grow in the garden. Many gardeners end up frustrated as their broccoli plants grow tall and healthy, but fail to produce the lush, dark green heads that are cooked up and served for consumption.
So why is my broccoli growing so tall? Broccoli plants grow tall as a result of stress. These plants require specific temperatures and nutrients to form a head of broccoli and without them; the broccoli plants will bolt upwards in an attempt to reproduce before it dies off.
So what kinds of stress are these plants receiving? As we talked about earlier, broccoli is somewhat of a tricky crop to grow. It requires specific growing conditions to produce a large, healthy head of broccoli. Many factors go into creating the right environment for your broccoli plants to thrive.
Broccoli is a crop that grows better in cold weather. But contrary to popular belief, the growth of broccoli is not affected by hot weather. Rather, it is affected by the temperature of the soil. Broccoli grows exceptionally well in soils that have temperatures that range between 65 F and 75 F.
Whenever the soil becomes warmer, the broccoli bolts up and begins to flower. If “why is my broccoli growing tall” is a question you have asked before, you now have an answer: bolting.
Bolting is when the cool weather plants such as broccoli begin to grow rapidly. Hence, the transition from the leaf phase to the flowering phase and then to the seed phase occurring very fast. In essence, bolting is a survival mechanism for the plant.
