Description
The 'Marathon' F1 Broccoli is a hybrid variety that produces blue-green heads with a fine texture. This broccoli has good tolerance to bacterial rots. It can be prepared in various ways: quickly sautéed, gratin, quiche, mashed, soup, etc. The plants of this variety can be planted from April to September for a harvest from June to November.
Broccoli, is a vegetable whose flowers are consumed just before they bloom. It offers beautiful firm heads, mostly green but sometimes purplish or white. Broccoli belongs to the large family of Brassicaceae (formerly Cruciferae), like Cabbages: Cauliflower, Brussels Sprouts, Smooth-leafed Cabbage (or Drumhead Cabbage), Savoy Cabbage (or Milan Cabbage), Green Cabbage or Kale, Kohlrabi, Chinese Cabbage, etc. Broccoli's Latin name is Brassica oleracea italica.
Although introduced to France by Catherine de Medici, under the name Italian Asparagus, Broccoli has only been cultivated on a large scale in France since the 1980s.
Originally from southern Italy, this broccoli with a mild flavour is now highly appreciated because it lends itself to many preparations. Steamed, it can be prepared in various ways: quickly sautéed, gratin, quiche, mashed, soup, etc. It is a low-calorie vegetable and rich in vitamin C.
Like almost all cabbages (except Brussels sprouts), Broccoli is a demanding vegetable. It requires excellent organic matter and regular moisture.
Harvest: Broccoli is harvested in two stages: first the main head and then the side shoots, by cutting with a knife. The harvest of this variety takes place from June to November.
Storage: It is best to consume Broccoli quickly after harvest as it does not keep well, only a few days in the refrigerator. You can also freeze it after blanching for 3 minutes in salted boiling water.
Gardener's tip: In recent years, the Cabbage Midge (Contarinia nasturtii), a small winged and sucking fly, has been causing damage to Broccoli in certain regions such as Brittany. We recommend opting for prevention by installing insect-proof netting tightly on market garden hoops throughout the flight period, from mid-May to mid-July. These nets are easy to set up and reusable to protect, for example, your carrot and leek crops.

Planting and care
The Broccoli is a greedy vegetable that requires a well-manured soil, rich in nitrogen and potassium. It is advisable, preferably in autumn, to generously add mature compost (about 3/4 kg per m2) by raking it to a depth of 5 cm (2in), after having, as for any vegetable crop, loosened the soil.
Planting: Plants of this variety can be planted from April to September for a harvest from June to November.
First, let the plug plants grow by transplanting them into trays or pots with a diameter of 8 to 13 cm (3 to 5in), filled with potting soil. Place them in a warm and bright location. Water regularly.
For planting in open ground, choose a sunny location (or partial shade if your summers are very hot). Space the plants 65 cm (26in) apart in all directions. Soak the root ball in water for a few moments before planting. Dig a hole, place the plant and cover with fine soil. Water thoroughly.
At the beginning of cultivation, it is advisable to mound soil around the base of the Cabbages to allow for better anchoring in the soil and root development.
Then, to reduce watering, we recommend mulching the soil with thin successive layers of grass clippings, if possible mixed with dead leaves.
During cultivation, water moderately but regularly.
The Broccoli, like all cabbages, is quite susceptible to diseases such as Clubroot and pests (Cabbage White, Cabbage Fly, Flea Beetle, Leaf Miner etc.). It is very important, for this crop, to pay attention to crop rotations.
It is beneficial to associate it with many vegetables such as tomato, or lettuce. However, avoid planting it near other Brassicas as well as zucchini, fennel, lamb's lettuce, leek and strawberry.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
