This geographical diversity results in varying temperatures and precipitation levels across the state.

When to Plant Calabrese Broccoli in Tennessee
The optimal time to plant Calabrese broccoli in Tennessee is in early spring or fall, depending on your hardiness zone. It’s recommended to start seeds indoors about 6-8 weeks before the last frost date in your area. The pre-grown seedlings can be transplanted outdoors once the soil temperature reaches around 50°F (10°C).
If you prefer to sow seeds directly in the garden, wait until the soil has warmed up to around 60°F (15°C) in the spring. In fall, you can sow seeds approximately 85-100 days before the first expected frost date, ensuring enough time for the crop to mature before winter.
Broccoli, a member of the cabbage family, is a cool-season crop that thrives in the moderate temperatures of spring and fall. It is rich in vitamins and minerals, making it a nutritious addition to your diet. Calabrese broccoli, specifically, is known for its large, blue-green heads and tender stalks, making it a popular choice among gardeners.
Step-by-Step Guide to Planting Calabrese Broccoli:
- Choose a location that receives full sun (at least 6-8 hours of direct sunlight daily) and has well-draining soil.
- Prepare the soil by adding organic matter, such as compost, to improve its fertility and drainage.
- Sow the seeds about ¼ to ½ inch deep and space them 18-24 inches apart.
- Water the seeds gently but thoroughly after planting.
- Maintain consistent soil moisture throughout the growing season, especially during dry spells.
- Keep an eye out for pests and diseases, such as cabbage worms, aphids, and powdery mildew. Use organic pest control methods when needed according to the instructions provided by agricultural authorities.
Broccoli plants are heavy feeders and will benefit from a side-dressing of compost or a balanced fertilizer halfway through the growing season. This will provide them with the necessary nutrients to develop strong, healthy heads. Additionally, mulching around the plants can help retain soil moisture, regulate temperature, and suppress weed growth.
Harvest your Calabrese broccoli when the heads are tight and compact, typically around 60-90 days after transplanting. Cut the main head at an angle, leaving some stem attached to encourage side shoots to develop for a continued harvest. Enjoy your homegrown broccoli steamed, roasted, or added to your favorite dishes for a fresh and flavorful culinary experience.
When to Harvest or Pick Calabrese Broccoli in Tennessee
Knowing when to harvest Calabrese broccoli is crucial to ensure you harvest the crop at its peak flavor and nutritional content. The average time from planting to harvest is around 60-90 days, depending on the variety and growing conditions.
Calabrese broccoli is typically ready to harvest when the main head reaches a diameter of around 4-6 inches and is firm to the touch. The buds should be tightly closed and dark green. If they start to separate or turn yellow, it’s a sign that the head is overripe and might have a bitter taste.
Harvest the main head by cutting it with a sharp knife about 5-6 inches below the head. This will encourage side shoots to develop, providing you with additional smaller broccolis to enjoy.

Step-by-Step Guide to Harvesting Calabrese Broccoli:
- Inspect the main head to ensure it has reached the desired size and quality.
- Using a clean and sharp knife, make a clean cut about 5-6 inches below the head, avoiding any damage to neighboring branches.
- Remove any leaves or debris from the harvested broccoli.
- Store the freshly harvested broccoli in a cool place or refrigerate it immediately to maintain its freshness and nutritional value.
- If you’re harvesting side shoots, continue to regularly inspect the plant and harvest them as they reach an appropriate size.
