Calabrese broccoli, also known as Italian green sprouting broccoli, is a popular variety that can grow to be quite large. The tight heads of this broccoli can reach up to 8 inches in diameter, making them a substantial addition to your garden.
One of the great things about Calabrese broccoli is that even after you harvest the central head, the plant continues to produce side shoots. These side shoots can be harvested as well, allowing you to enjoy fresh broccoli right up until the first frost.
In my personal experience, I have found that Calabrese broccoli plants can actually vary in size. While 8 inches is the maximum diameter, some heads may be slightly smaller, around 6 or 7 inches. However, this still provides a generous amount of broccoli to enjoy.
When growing Calabrese broccoli, it is important to provide the plants with adequate space to grow. Plant them at least 18-24 inches apart to allow for proper air circulation and to prevent overcrowding. This will help ensure that the heads can develop to their full size.
Additionally, providing the plants with well-draining soil that is rich in organic matter can also contribute to their overall growth and size. Broccoli plants are heavy feeders, so adding compost or well-rotted manure to the soil before planting can provide them with the nutrients they need to thrive.
Regular watering is essential for Calabrese broccoli plants, as consistent moisture helps support their growth. However, be careful not to overwater, as this can lead to root rot and other issues. Aim for about 1-1.5 inches of water per week, either through rainfall or irrigation.
Pruning and harvesting the central head of the Calabrese broccoli plant is a simple process. Once the head reaches the desired size, you can cut it off using a sharp knife or shears, making sure to leave a few inches of stem attached. This will allow for the development of side shoots.
After the central head is harvested, you can continue to enjoy fresh broccoli by harvesting the side shoots as they mature. These shoots will continue to produce until the weather becomes too cold, making Calabrese broccoli a long-lasting addition to your garden.
Calabrese broccoli can grow up to 8 inches in diameter, providing a substantial harvest for your garden. By providing the plants with proper spacing, nutrient-rich soil, and regular watering, you can help support their growth and maximize their size. Harvesting the central head and then enjoying the side shoots ensures a continuous supply of fresh broccoli until the first frost.
