1. Preparing the Ground

Calabrese is a lovely vegetable to grow, and it thrives in firm, fertile, well-drained soil that gets plenty of sunlight or light shade. It’s always best to prepare your growing site in advance, ideally in the autumn before planting. You can add two bucketfuls of well-rotted manureor garden compost per square meter/yard and let it settle over winter.

Alternatively, if you are planting closer to the time, you can firm the soil by treading it down and raking it smoothly. It’s worth noting that if your soil is very acidic, you should apply lime the previous winter to raise pH and prevent clubroot disease. The ideal pH for Calabrese broccoli is at least 6.8, which you can test using a pH testing kit from your local garden centre or online. Once you have checked your soil pH, you can rake in a high-potassium general fertilizer, such as Vitax Q4. Use one and a half handfuls per square meter/yard or three handfuls if you haven’t added any manure or garden compost to the soil. With these simple steps, you will be on your way to growing delicious Calabrese in your own backyard.

2. Sowing Seeds Indoors

While growing indoors, it’s a good idea to sow the seeds in March-April and start the modules under cover. However, keep in mind that Calabrese does not like any root disturbance, so try to minimize this as much as possible during growth. Fill the modules with compostand sow two seeds per module, then cover lightly with more compost and gently water.

Keep them on a windowsillor in a greenhouse, making sure they have plenty of light and not too much heat. Water sparingly to encourage the roots to search for water in the compost. Once your seedlings are around 8cm tall with a few true leaves, they are ready to be planted outside to avoid root congestion, which usually happens after five or six weeks.

3. Directly Sowing Seeds Outdoors

To get the best results for your calabrese broccoli, direct sowing in late spring can work great. It’s important to be prepared and protect the young plants from frost by using a clocheor cold frame if needed. There are two options available while direct sowing. The first is to sow in a seed bed for transplanting later, and the second is to sow in situ. When direct sowing in situ, sow in rows that are 18-25 inches (40-50cm) apart.

Sow two or three seeds every 10-12 inches (25-30cm) along the row, and then cover them with soil at a depth of 3-4 inches (2cm). Seedlings should emerge in about two weeks. Once they are large enough to handle, thin them to one plant every 12 inches (25cm). If you are transplanting, do so after five weeks of sowing or once the plants have four or five leaves, spacing them 20-24 inches (50-60cm) apart. With this method, you will have a healthy crop of Calabrese Broccoli.

4. Planting Process of Broccoli ‘Calabrese’

When growing calabrese seedlings indoors, it’s important to harden them off for 1-2 weeks. You acclimatize the seedlings by gradually increasing the amount of time they spend outside each day. Once they are about 6 inches tall, pick a dull day or evening to plant them out. Spacing is important, with 20-25 inches for large varieties and 15 inches for more compact ones. Secondary harvests can also be achieved with proper spacing. Plant the seedlings carefully, making sure the base is secure and not over-watering. If planted in June-July in a well-dug veg bed or large containers, they should be ready to harvest from August-October.

How to Harvest Broccoli ‘Calabrese’

Calabrese is best harvested in late Summer and Autumn when the main head is 10-15 cm (4-6 inches) across and still in bud. It’s important to harvest it promptly to prevent the flowers from opening. After the main head is harvested, small heads will develop on side shoots which can be regularly picked over the following weeks; the young leaves are also edible. To ensure continuous harvesting, it’s important to check plants every few weeks.

Calabresebroccoli is delicious when lightly steamed, sautéed, or stir-fried, but be careful not to overcook it. It should be used right after harvesting to get the most flavour; nutrients like nitrogen, phosphorus, and potassium are important for plant growth and can be added through fertilizers. Other vital soil nutrients include magnesium, calcium, and sulfur. Calabrese can be kept in the fridge for a few days or frozen for later use.

Caring Tips for Broccoli ‘Calabrese’

Calabrese, like other brassicas, is susceptible to common plant diseases. So always look out for signs of cabbage root fly, which causes blue-tinged leaves that wilt in sunny weather. Usually, young plants are most vulnerable to this pest, so protect them with cabbage collars or mesh. Cabbage caterpillars can also be a problem, laying clusters of yellow eggs under leaves which hatch into destructive caterpillars. Check the underside of the leaves periodically to brush off the eggs, and use insect mesh to preserve butterflies from laying eggs.

Leatherjackets and cutworms can cut stems at ground level, killing seedlings. Use nematode-based natural insecticides to control them. Additionally, pigeons are attracted to emerging heads and leaves of Calabrese, so protect young plants with mesh netting or fleece. Flea beetles may also make small holes in leaves in April and May, but you can prevent them by using nitrogen-rich fertilizer and grease-covered cardboard traps.
