Growing Instructions for Cold Weather Gardeners
Calabrese Broccoli thrives in cooler weather, making it a perfect choice for gardeners in northern regions or those looking to extend their growing season into the cooler months. To get a head start, sow seeds indoors 6-8 weeks before your last expected frost. Use seed trays or biodegradable pots, planting the seeds ¼ inch deep in a well-draining seed-starting mix. Keep the soil evenly moist and place the trays in a sunny spot or under grow lights.
Once your seedlings have developed several true leaves and the outdoor temperature stays above 50°F, begin the hardening-off process by gradually introducing the plants to outdoor conditions. Transplant them into your garden or containers, spacing them 18-24 inches apart to allow room for their large, bushy growth. Choose a sunny location with well-draining, fertile soil. Adding organic compost before planting can help provide the nutrients Calabrese Broccoli needs to thrive.
Water regularly to keep the soil evenly moist, but avoid waterlogging. Mulching around the plants can help retain moisture and regulate soil temperature, especially in colder climates. As the heads form, check them regularly and harvest when they are tight and firm, cutting them from the plant. Side shoots will continue to grow after the main head is harvested, extending your broccoli harvest over several weeks.
Calabrese Broccoli is a rewarding, cold-hardy crop that offers both high nutritional value and delicious flavor. It’s a must-grow for gardeners who appreciate heritage varieties and robust, consistent yields.
