To ensure healthy growth and maximize your yield, it is crucial to give broccoli plants enough space to develop properly. Crowding them can lead to stunted growth, reduced airflow, increased susceptibility to pests and diseases, and ultimately lower yields. 

The following guidelines will help you determine the ideal spacing for your broccoli plants:

  1. Row Spacing: Broccoli plants are typically grown in rows. For efficient spacing, leave approximately 18 to 24 inches of space between each row. This allows ample room for plants to spread their foliage and facilitates easy access for maintenance tasks such as weeding and harvesting.
  2. Plant Spacing: Within each row, it is recommended to space broccoli plants 12 to 18 inches apart. This broccoli plant spacing ensures adequate airflow between the plants, reducing the risk of diseases that thrive in moist, crowded conditions. It also allows each plant to receive ample sunlight for optimal growth and head development.
  3. Square Foot Gardening: If you practice square foot gardening, which is a popular method for maximizing yield in small spaces, you can grow a single broccoli plant per square foot. In this approach, the plants are spaced 12 inches apart in all directions, allowing each plant to utilize the entire square foot for growth.

Adhering to these spacing guidelines will help you create a healthy and productive broccoli garden. However, keep in mind that the specific recommendations may vary slightly depending on the variety you choose to grow.

How Many Broccoli Plants Per Square Foot?

On average, it is recommended to plant broccoli at a spacing of 18 to 24 inches apart in rows, with rows spaced 30 to 36 inches apart. This spacing allows sufficient room for each plant to develop a healthy root system and ensures adequate airflow between the plants, reducing the risk of diseases. Based on this spacing, you can calculate the number of plants per square foot.

If we assume a spacing of 18 inches between plants within a row and 30 inches between rows, each broccoli plant would occupy approximately 1.25 square feet of space. The area that the plant itself occupies as well as the distance between rows are both taken into account in this calculation. Therefore, in a square foot area, you could typically accommodate around 0.8 to 1 broccoli plant.

However, it’s worth noting that some gardeners prefer to grow broccoli more intensively, especially in raised beds or containers where space is limited. In such cases, you may opt for closer spacing between plants, such as 12 inches apart in rows, which would allow for approximately 1.8 to 2 plants per square foot. This approach requires careful monitoring of nutrient levels and moisture levels to ensure each plant receives adequate resources for optimal growth.

Keep in mind that overcrowding the plants can lead to competition for resources, stunted growth, and an increased risk of pests and diseases. Conversely, providing ample space allows each broccoli plant to develop a robust root system, access nutrients and water efficiently, and receive adequate sunlight for photosynthesis.
