In winter, nothing grows! We mustn't stop at our mental representations. Winter doesn't have to be a dead season for your vegetable garden. It can also be a period rich in harvests and surprises. As the cold sets in and nature goes to sleep, your garden can still offer you fresh vegetables.
Having a vegetable garden is a great way to get your kids excited, even in winter. It's like an open-air classroom. By watching plants grow, they discover the effect of the seasons on nature, learn to recognize life cycles and understand the importance of biodiversity.
Digging in the earth, sowing seeds and watching the first shoots appear allows them to explore the fascinating life of the soil, populated by earthworms, bacteria and fungi. It's also an introduction to biology, with every gesture becoming a lesson in the ecosystem. The vegetable garden awakens their curiosity, nurtures their respect for the environment and cultivates their patience. It creates a connection with nature.
Winter is not a season of inactivity for your vegetable garden. It's the ideal time to grow cold-hardy vegetables, which are used to cool temperatures and offer generous harvests even under the snow. Here are some suggestions on what to plant in winter and how to organize your seedlings.
Winter has its stars, those hardy vegetables that brave the frost. Among them, there are three main families:
Root vegetables: These winter garden staples thrive underground, sheltered from the cold. Carrots, slightly sweetened by frost, parsnips with their subtle flavor, crisp turnips and colorful beets are perfect for comforting soups or tasty gratins.
Leafy greens: Some plants don't mind the cold, and continue to grow despite the frost. Spinach, rich in nutrients, lamb's lettuce, tender and delicate, kale, with its generous leaves, and winter lettuces, such as escarole and chicory, are sure to liven up your salads and warm dishes.
Perennial vegetables: They make it through winter without a hitch. Leeks, with their slightly sweet taste, cabbages (head, Brussels or kale) and broccoli, which stand up well to low temperatures, enable harvests spread over several months.
To maximize your chances of success, choose hardy varieties specially adapted to winter conditions. Among the most popular are :
Tardif d'Angers' cabbage, which produces beautiful apples even in winter.
Crapaudine' beet, an old variety with intense flavor and firm flesh.
Verte de Cambrai' lamb's lettuce, cold-hardy and perfect for winter salads.
These varieties, selected for their hardiness, will guarantee you abundant, tasty harvests, even when the mercury drops.
To make a success of your winter vegetable garden, you need good planning. Here are a few guidelines to help you organize your planting:
Summer sowing: Slow-growing vegetables, such as carrots, cabbages or leeks, should be sown in the summer to give them time to develop before the cold weather sets in. These vegetables need several months to reach maturity, so plan ahead!
Autumn sowing: For fast-growing vegetables such as spinach or lamb's lettuce, early autumn sowing is sufficient. These plants take advantage of the last soft spells of autumn to establish themselves, and continue to grow slowly through the winter, offering harvests in the early months of the following year.
Winter can be harsh, but with the right techniques, your vegetables can not only survive, but thrive despite the cold. You need to protect your crops to ensure abundant, tasty harvests. Here's how to create a favorable environment for your plants during the colder months.
There are several ways to protect your crops from frost and bad weather, while maintaining optimum growth:
Mulching
A thick layer of mulch (straw, dead leaves, compost) is your first line of defense. It insulates the soil, retains heat and protects vegetable roots from frost. It also limits water evaporation and prevents weeds from taking hold.
Forcing sails
These light, permeable fabrics are ideal for protecting vegetables while letting in light and air. They create a barrier against the cold and icy winds, while allowing plants to breathe. Ideal for lettuces, spinach or seedlings.
Tunnels and frames
These simple structures made of plastic- or glass-covered hoops create a warm, humid microclimate. They are ideal for extending the growing season and protecting the most sensitive vegetables. Easy to install and move, they can be adapted to any size of vegetable garden.
Greenhouses
For the most ambitious gardeners, a greenhouse offers maximum protection. They enable you to grow vegetables all winter long, even in the coldest regions. By combining greenhouse and mulch, you can create the ideal environment for continuous harvests.
The location of your crops plays an important role in their resistance to the cold. Here are a few tips for finding the best location for your winter vegetable garden:
Take advantage of sunny areas: Place your crops in the sunniest parts of your garden. South or south-west exposure is ideal for capturing maximum light, even in winter.
Shelter from the wind: Cold winds can damage plants and accentuate the effects of frost. Use hedges, fences or walls to create sheltered areas. Low walls, in particular, store heat during the day and release it at night.
Use existing walls and structures: The walls of your house, garage or even garden sheds can act as natural heat reserves. By placing your crops close to these structures, you benefit from the heat they store.

Winter is a season of rest for nature, but not for the gardener! Even if activity in the vegetable garden slows down, a few maintenance gestures are essential to preserve the health of your crops and prepare the ground for spring. Here's how to care for your vegetable garden during the cold months.
In winter, your plants' need for water diminishes considerably, but that doesn't mean you should neglect them. Here are a few watering tips.
Limit watering: In the open ground, winter rainfall is generally enough to keep crops hydrated. But in greenhouses and tunnels, moderate watering is essential. Keep the soil slightly moist, but not excessively so.
Water in the morning: Water early in the day to allow water to soak in before temperatures drop in the evening. This prevents the water from freezing around the roots, which could damage the plants.
While there are fewer pests in winter, some remain active and can threaten your crops. Here's how to keep them at bay:
Watch out for rodents: field mice and voles, fond of roots, can cause serious damage. Protect your vegetables with buried fences or environmentally-friendly traps.
Slugs: Even in winter, slugs can attack young shoots. Use natural barriers (ash, crushed eggshells) or beer traps to keep them away.
Regular monitoring will enable you to intervene quickly and preserve your crops.
Winter is the ideal time to think about the organization of your vegetable garden and prepare the soil for future crops. Crop rotation is an essential practice for maintaining soil fertility and avoiding nutrient depletion.
Alternate vegetable families: Don't plant the same vegetables in the same place from one year to the next. For example, after root vegetables (carrots, turnips), opt for leafy vegetables (spinach, lettuce) or legumes (peas, beans), which enrich the soil with nitrogen.
Prepare the soil for spring: Take advantage of winter to enrich the soil with compost or green manures. This will nourish the soil and make it more fertile for future planting.
What if you could grow vegetables all year round, even in the dead of winter, without the need for heating? That's the challenge of the semi-underground greenhouse, a technique inspired by the Bolivian Walipini model. By exploiting the thermal inertia of the soil, this greenhouse maintains a stable temperature conducive to plant growth, even when the mercury drops outside.
The principle is simple but ingenious: by partially burying the greenhouse, we take advantage of the soil's capacity to store heat. During the day, the earth absorbs the sun's heat and slowly releases it at night, creating a warm, constant microclimate. This thermal inertia prevents sudden temperature variations, providing an ideal environment for crops, even in winter.
Year-round cultivation: Thanks to this technique, you can harvest vegetables in winter and even grow tropical plants, without the need for expensive heating systems.
Energy savings: By using the natural heat of the soil, you reduce your energy consumption while protecting the environment.
Protection from the elements: Partially buried, the greenhouse is less exposed to wind and cold, making it a robust and efficient structure.
To optimize your greenhouse's performance, there are a few rules to follow:
Exposure to the sun: orient the greenhouse towards the south to maximize sunlight in winter.
Depth: Bury the greenhouse 2 to 2.5 meters deep for optimum thermal inertia.
Transparent roof: Use a sloping plastic or glass roof to catch the sun's rays while avoiding overheating in summer.
Drainage and ventilation: Ensure good drainage to avoid water infiltration, and install a ventilation system to regulate temperature in summer.
The semi-underground greenhouse is a sustainable, low-cost alternative to traditional greenhouses. Whether you're a home gardener or a permaculture enthusiast, this technique will enable you to prolong your harvests and grow fresh vegetables even in the coldest months.
The climate where you live is obviously a crucial factor for vegetable gardening. If temperatures are too cold, the soil will be so hard that it will be impossible to do anything. Conversely, if you live in a region with a Mediterranean climate, you'll have plenty of opportunities.

Does It Work to Encourage Behaviors in Education?
In 2008, the specialist Richard Thaler explained the concept of behavioural incentives. The idea is to subtly influence a person to adopt a desired behaviour. In marketing, this often leads to a purchase. But it can be used in other areas, including education. Does gently encouraging students to study better work? It can when it is well thought out.
