F1 Marathon

The F1 Marathon Calabrese is one of the most reliable summer broccoli varieties, producing medium-sized, dense, deep green heads on sturdy plants that thrive in almost any soil. Slow to bolt and resistant to disease, it offers a long cropping season with consistently high-quality harvests.

Harvest
June to October

Growing Instructions

Planting: Space plants 30cm apart in well-drained soil, ideally in partial shade.

Watering: Keep well-watered until established and during dry weather.

Protection: Guard against cabbage white butterflies in summer with netting or organic methods.

Top Tips

• Steam rather than boil to preserve the rich color and vitamins.

• Leaves can also be cooked and enjoyed as a nutritious winter green.

• Calabrese vs. Broccoli: Calabrese are smaller plants grown from spring to early summer, producing large green heads the same year. Broccoli (or sprouting broccoli) is usually an overwintering type with larger plants and many small florets, harvested from late winter through spring.
