If you see flowers growing on your broccoli plant, it’s a sign that the plant is about to bolt. Bolting is when a plant produces flowers and then seeds, which can negatively impact the quality and taste of the vegetable. When broccoli bolts, the stems become woody, the leaves become bitter, and the broccoli heads become smaller and less flavourful.

To prevent your broccoli from bolting, there are a few things you can do:
Harvest Your Broccoli Early
Broccoli is a cool-weather crop, and it’s best to harvest it before the temperatures start to rise. If you wait too long to harvest your broccoli, the plant may bolt. Be sure to harvest the broccoli head when it is still firm and tight.
Provide Adequate Water
Broccoli plants need consistent moisture to grow and thrive. If the soil becomes too dry, the plant may bolt. Make sure to water your broccoli regularly and keep the soil evenly moist.
Provide Adequate Nutrients
Broccoli plants need adequate nutrients to grow and produce healthy heads. If the plant is nutrient deficient, it may bolt. Make sure to provide your broccoli with a balanced fertiliser and follow the instructions for application.
Provide Adequate Light
Broccoli plants need at least six hours of direct sunlight per day to grow and produce healthy heads. If the plant is receiving inadequate light, it might bolt. Ensure that the indoor broccoli are provided with a bright, sunny location or use grow lights to supplement natural light.
If your broccoli plant has already bolted and is producing purple flowers, unfortunately, there’s not much you can do to save the broccoli head. However, you can still harvest the leaves and stems and use them in salads or stir-fries. You can also allow the plant to produce seeds, which you can save and use to grow more broccoli in the future.
Preventing your broccoli plant from bolting is key to producing healthy and flavorful broccoli heads. By providing your plant with adequate water, nutrients, and light, and harvesting the broccoli head early, you can avoid the problem of purple flowers and enjoy delicious, home-grown broccoli all season long.
