Successfully maintaining a garden year-round requires measuring the gaps between what each season demands and what most gardeners actually practice. The Ifop barometer for Unep, published in March 2025, shows that the French are changing their gardening habits: collecting rainwater, choosing drought-resistant plants, creating habitats for biodiversity. These trends are reshaping maintenance priorities, season after season.
Water in the garden: comparing actual needs and common practices
Watering remains the area where the gap between theory and practice is the widest. The majority of gardeners water on a fixed schedule, without considering the growth stage or the week’s weather.
| Period | Water needs (trend) | Common practice | Observed gap |
|---|---|---|---|
| Spring | Moderate (root recovery) | Abundant watering at the first signs of heat | Overwatering, risk of seedling rot |
| Summer | High but variable depending on species | Daily surface watering | Water lost to evaporation, shallow roots |
| Autumn | Low to none (natural rainfall) | Watering maintained out of habit | Excess moisture, fungal diseases |
| Winter | Almost none | Watering stopped | Correct in most cases |
The table highlights a recurring pattern: summer surface watering wastes water without nourishing deep roots. Less frequent but prolonged watering, early in the morning, forces roots to go deeper in search of moisture.
Water restrictions complicate matters. The national framework distinguishes four levels (vigilance, alert, heightened alert, crisis), but the concrete measures vary from one municipality to another. Checking local zoning before installing a timer avoids unpleasant surprises. On bon-jardinier.fr, practical sheets detail watering techniques suited to each type of soil and climate.
Choosing plants and climate adaptation: what the AVEC program changes
The classic advice to “choose plants suited to your soil” is no longer sufficient. The AVEC program from ADEME, updated on July 23, 2025, evaluated tree, shrub, and climbing plant species based on two rarely combined criteria: their ability to withstand future climate stresses and their cooling potential.
This framework alters decision-making at planting time. A shrub that thrives today in clay soil in northern France may struggle in ten years if drought episodes increase.
Plants to prioritize based on expected stress
- For dry soils and long summers: Mediterranean shrubs (cistus, lavenders, rosemaries) that tolerate several weeks without water once established
- For urban gardens exposed to heat islands: climbing plants with high cooling power, capable of covering a wall or pergola in a few seasons
- For vegetable gardens: heirloom varieties of tomatoes or squash, selected from warm terroirs, which require less watering than common hybrids
- For hedges: local deciduous species rather than exotic evergreens, which better withstand freeze/drought alternations
The reflex to acquire: cross the nature of the soil with the climate projections for your region before any purchase at a garden center.
Soil and vegetable garden maintenance: the actions that really matter
The soil concentrates the majority of silent errors. Compacted soil from winter foot traffic or depleted by repeated crops without rotation produces mediocre results, regardless of plant quality.
Preparing the soil in spring without turning it
Turning the soil with a spade destroys the biological structure of the soil. Raking the top five centimeters, then mulching, preserves the organisms that decompose organic matter. Mulching reduces evaporation and limits weed growth without resorting to chemical weeding.
Green manures in autumn: a measurable investment
Sowing mustard, phacelia, or crimson clover between September and October occupies bare soil, fixes atmospheric nitrogen, and loosens the ground thanks to taproots. The following spring, it is enough to mow and superficially incorporate the plant mass.
This technique, still little practiced in private gardens, produces a visible effect from the first year: the soil becomes more pliable and retains water better after just one cycle of green manure.
Pruning and lawn care: adjusting the schedule to the garden’s signals
Pruning “at the right time” depends less on the calendar than on observation. A forsythia is pruned just after flowering, not on a fixed date. A remontant rose is pruned at the end of winter when the buds swell, not because March is marked on a schedule.
For the lawn, mowing high (seven to eight centimeters in summer) slows drying and encourages deeper rooting. Mowing short in high heat weakens the grass and leaves the field open to weeds.
Year-round garden maintenance relies on three measurable levers: managing water according to actual needs, choosing plants suited to the upcoming climate, and maintaining a living soil nourished by cover crops. The rest, pruning, mowing, fertilizing, stems from direct observation of the ground rather than a fixed calendar.
