Oats and field peas make a very interesting combination, as they both grow very quickly and are quite cold-hardy. This mixture provides excellent ground cover, making weed growth virtually impossible. As with oats, this mixture is ideally used for a period of two months, either before or after a main crop.

• Oats and peas grow in all types of soil. Germination takes between 5 and 14 days.
• They can be sown as soon as the soil can be worked in April and until the beginning of September in soil between 1 and 24 °C.
• They are sown broadcast and the plants are turned back into the soil as green manure after 30 to 65 days.

• Compared to oats, the root mass of peas is very small, but its ability to fix nitrogen in the soil is almost double.

• This mixture is well suited to cold conditions, but will not survive the winter.

• Seeding rate: 2 kg/100 ^m² – 4 lb/1000 sq ^ft

Although this technique dates back more than 2500 years, contemporary agronomists have only recently discovered its immense potential. In our opinion, biochar is nothing less than the missing (and now found!) link in living soils .

Optimal ratio to be achieved gradually (1 to 5 years), according to several application methods: 1 kg/1 m2 of soil (consult the application guide ).

Fine particle size is more easily introduced into small or narrow containers (in multi-cell trays, for example) and is recommended for "living mixtures" (biochar + compost).

Buckwheat is very well adapted to poor soils and is renowned for its excellent weed-suppressing properties. Its rapid growth makes it a perfect choice for use before or after the main crop, as it can be plowed into the soil after only 30 to 40 days, which coincides with the start of its flowering.

• Buckwheat, used as a green manure, takes 30 to 65 days to grow. Its well-branched root system allows for good structuring of the top few centimeters of soil.
• This plant is a phosphorus extractor that purifies the soil.
• The most effective green manure for smothering weeds.
• Very sensitive to cold, buckwheat must be sown once the risk of frost has passed (from the beginning of June to the end of July in soil at 15-25 °C).
• The seeds germinate in 2 to 6 days and the plants are returned to the soil as green manure after 30 to 65 days.
• Although its flowers attract many beneficial insects, it is best to bury them when they appear to prevent them from making seeds.
• Seeding rate: 2 kg/100 ^m² – 4 lb/1000 sq ^ft

Tansy-leaved phacelia is a very versatile herbaceous annual used as an ornamental and bee-friendly plant, but also as a green manure, cover crop, or forage crop! Highly adaptable, it grows in semi-arid to humid climates, by the sea as well as inland and in the mountains. It prefers light and rather dry soils, but tolerates different soil types.

• Its extensive root system helps to improve soil structure, particularly in the case of compacted soils (unstable, rather silty soils and compacted clay soils whose surface cracks when drying).
• Early sowings yield up to 4.5 t/ha of vegetative biomass, while late sowings yield only about 1.25 t/ha.
• It is sown from the end of April to the beginning of June, depending on the region, because the soil temperature must be maintained between 13 and 18 °C for good germination.
• Phacelia is sown at a rate of 10-15 kg/ha at a depth of 0.5 cm. A good seedbed is prepared and then covered with soil. Small plots can be broadcast and then covered with a layer of soil, but for larger plots, it is better to use a vegetable seed drill.
• Especially in dry weather, rolling the plot after sowing is strongly recommended.
• Phacelia can also be sown in association with buckwheat at a rate of 8 kg/ha of phacelia to 40 kg/ha of buckwheat.
• Because of its ability to attract beneficial insects and improve soil health, phacelia can help reduce the incidence of certain diseases and pests.

Passed down from generation to generation, the Sainte-Anne shallot is a prolific perennial deeply rooted in Quebec's horticultural heritage. Cultivated for over 70 years in Sainte-Aurélie, in the Chaudière-Appalaches region, it is distinguished by its hardiness and its ability to return year after year, faithfully following the seasons.

Traditionally planted around July 26th, Saint Anne's Day, it embodies a living link between collective memory and farming practices. Each bulb buried in suitable soil can produce up to ten offshoots the following season, forming upright and vigorous clumps that require little but yield much. Not invasive, it encourages patient and rhythmic cultivation, where the annual division of the bulbs ensures vitality and abundance.

In a supportive vegetable garden, it naturally settles in quiet corners, in the shade of attentive gestures, highlighting the continuity of an inhabited garden.

The Jerusalem artichoke ( Helianthus tuberosus ), a hardy relative of the sunflower, originated in North America, where its tubers nourished Indigenous peoples long before its arrival in Europe. The Red Spindle variety is distinguished by its elongated, reddish-skinned tubers, which are more uniform than those of wild types, making it a valued companion in edible gardens.

In favorable soil, its tall, upright, leafy stems form a living screen that accompanies the entire cycle of seasons. Its late flowering, with small yellow flower heads reminiscent of miniature sunflowers, brings a touch of brightness to the garden in late summer. Underground, the tubers develop patiently and, in autumn, offer a generous harvest for cooking, while also allowing the gardener the freedom to leave some for the following season.

Hardy and adaptable, the Red Spindle variety integrates naturally into a harmonious garden, where simplicity of care is valued as much as rich soil and biodiversity. It is a reliable plant, ideal for establishing a respectful and long-term approach to gardening.

Native to the wetlands of North America, Apios americana , often called string bead or tuberous wisteria, weaves its supple stems through the vegetation, as if recalling the ancient bonds between people and their food plants. Its tubers form along underground stolons, in more or less spaced strings, and constitute a valuable energy reserve for burrowing fauna and, where it is known, for curious gardeners.

This climbing perennial from the Fabaceae family thrives in moist to wet soils and in sunny to partially shaded locations. Its reddish-brown to purple flowers, arranged in dense clusters, bring a discreet yet distinctive presence to the heart of the living garden. Far removed from rushed cultivation, Apios establishes itself deeply and requires time: it readily integrates into a perennial, nourishing space, where the slow development of its tubers can be observed over the seasons.

A cousin of the broad bean, the fava bean originates from ancient Egypt, where it was among the first cultivated plant species. The Greek philosopher Pythagoras and his followers forbade themselves from consuming its beans, considering them to be of the same substance used to create human beings. It was said that the beans served as a place of transmigration for souls and that eating them was tantamount to feeding on the dead. Legend has it that Pythagoras was overtaken and killed by his enemies because he refused to flee through a field of fava beans!

• The broad bean is very resistant to cold and tolerates poor or clay soils and high levels of mineral salts.
• Its pea-like pods have been part of the human diet for millennia, as a vegetable or as flour.
• They are also valued in animal feed, but the plant itself is a champion at enriching the soil with nitrogen.
• It can be sown as soon as the soil can be worked in April and until the beginning of September, in soil between 1 and 24 °C.
• The seeds germinate in just 3 to 6 days.

• It is sown in furrows 2-3 cm deep, leaving ± 10 cm between plants.
• The plants are returned to the soil as green manure after 30 to 65 days.
