Germination period: 7-10 days
Hours of sunlight required: Broccoli requires full sun exposure (at least 6 hours per day) to grow and develop properly.
Watering: Broccoli requires regular watering to maintain soil moisture, but it is sensitive to overwatering. Water deeply once or twice a week, depending on the weather and soil conditions.
Companion crops: Broccoli grows well with other cool-season crops, such as cauliflower, cabbage, and Brussels sprouts.
