Calabrese Marathon F1, this very prolific variety is a tasty, deep-green with a large, central flower head, followed by lots of smaller side shoots. It grows quickly and will mature three months from sowing in mid-spring for harvesting from summer until the frosts.
When growing Calabrese, choose a sheltered position in firm, rich fertile, well-drained soil in full sun. Prepare the soil in early spring by adding plenty of well-rotted farmyard manure to the soil to improve its structure and fertility. Take care when transplanting Calabrese as it resents root disturbance. Plant Calabrese at a distance of 22cm (9") apart, and cover with a protective netting or fleece to prevent attack from birds and insects. Water the plants thoroughly after planting.
Sow broccoli seeds in a well-prepared seed bed from March to June at a depth of 13mm (½") and spaced 30cm (12") apart. Transplant to their final positions around 5 weeks later when the seedlings have four or five leaves.

Cut the main crown when in tight bud. Side shoots will subsequently develop. Lower crop density gives a longer period of harvest, as more secondary heads are produced.
The heads must be cut whilst in tight bud; once per week in cool weather, and twice a week is essential in warm weather.
Suitable for the vegetable garden, allotments and containers.
Be prepared to water well and supplement feed with high-potash feed during season. Regular feeding is recommended.
