Product Information

Calabrese seeds are widely available from garden centres and online gardening retailers (although, confusingly, they are sometimes sold as broccoli). This should give reliable results, as seedlings are protected from harsh weather and pests such as slugs, however calabrese doesn’t like root disturbance, so take great care when transplanting. To grow well, plants need a wide range of nutrients in various amounts, depending on the individual plant and its stage of growth. If your soil is very acidic, apply lime the previous winter to raise the pH and deter clubroot disease.

Begin by charring the peppers in a smoking hot griddle pan or directly over a gas hob flame, rotating as the skin blackens.Calabrese and broccoli are two different crops, but they are often muddled up, with both plants widely referred to as broccoli. Larger varieties and those in exposed sites should be given additional support – insert a sturdy cane and tie in the main stem to hold it secure. Calabrese should be grown in the same bed as its other cabbage relatives in crop rotations, to avoid any build-up of pests and diseases in the soil. Calabrese is mainly sown in spring, either indoors or outside, and is ready to harvest in three or four months, from July to October, depending on the variety and sowing time.

Gardeners can add nutrients by applying fertilisers (either artificial or naturally derived) to boost plant growth and improve flowering and fruiting. If you have clubroot disease in your soil, sow calabrese indoors so it can develop a good root system before being moved into the ground. From our delicious hand-stretched, stone baked pizzas, to our classic pastas, gluten free options and bundles, we’ve got you covered! Regular harvesting encourages plants to produce further small heads, extending the cropping season for up to a couple of months.Covering the crop with fine-mesh netting, supported on a framework, will keep several pests at bay, including cabbage caterpillars and pigeons. Once they have a good root system, they should only need watering during dry spells, to avoid any check in their growth, which could cause them to bolt (flower prematurely). The previous autumn, dig in two bucketfuls of well-rotted manure or garden compost per square metre/yard, to allow the ground time to settle over winter. For the most reliable calabrese varieties, look for those with an RHS Award of Garden Merit (AGM), which shows they performed exceptionally well in trials – see our list of AGM fruit and veg for recommended varieties of calabrese and many other crops. Packed with seasonal flavours, our hand stretched classic tomato base is topped with slices of roasted aubergine, creamy Burrata and sun-blushed tomatoes.

A popular and tasty crop, calabrese produces large domed green heads up to 15cm (6in) across, for harvesting in summer and autumn. Calabrese seeds are generally sown between February and June – indoors from late winter into mid-spring, then outdoors from mid-spring to early summer. You’ll find a wide selection of calabrese varieties available as seed, offering variations in sowing/harvesting times, plant size, and resistance to bolting, clubroot and other diseases.Calabrese should be used straight after harvesting if possible, when packed with flavour and nutrients, but can be kept in the fridge for a few days or frozen for later use. Plant young calabrese deeper than they were previously growing, with the lowest leaves level with the surface, so they root in securely.

Keep plants fully covered with fine-mesh netting to protect them from cabbage butterflies and pigeons. After you harvest the main head, further small heads will develop on side-shoots, which can be picked regularly over the following weeks.If sowing in their final position, sow three seeds every 30cm (1ft) along the drill, then thin out each cluster of seedlings to leave just one at each point.
