  • In the ornamental garden, mulch to prevent weeds. Cover the soil around shrub and perennial plants with a 5 to 10 cm layer of shredded bark or dead leaves. Pine bark is the most effective weed control material because its high tannic acid content blocks the germination of weed seeds. Renew your mulch regularly. Photo Fiskars

  • For your lawn, mow high and regularly. Set your mower to a cutting height of six to eight centimeters. A dense, tall lawn naturally smothers unwanted weeds. Mow weekly during the growing season to prevent the lawn from becoming exhausted. Avoid mowing too short: this weakens the grass and encourages the establishment of moss and weeds.

  • In the vegetable garden, sow green manures In the vegetable garden, after harvesting, do not leave the vegetable beds bare, because weeds have free rein and can multiply by reseeding themselves. It is preferable to sow green manures, most of which germinate quickly and form a dense plant cover. Lupins and other papilionaceae help loosen compacted soils and enrich them with nitrates.

  • Weed by hand regularly. In the vegetable garden, hoe once a week to loosen the surface soil. This reduces water evaporation from the soil and helps control weeds. At the seedling stage, unwanted plants are more fragile, and the moist soil makes them easier to pull out. Intervene early, before the weeds go to seed. Photo Fiskars
  • Brush the paths rather than weeding. To remove weeds from your paved paths, use a wire brush with a handle or a thermal weeder. In spring, work every two weeks to prevent weeds from taking root. Fill the gaps with sand or gravel to limit regrowth. Photo Ribiland

  • Cover crops with canvas. In the vegetable garden, place burlap or biodegradable woven tarps between the rows. This limits weed growth while allowing your crops to thrive. Secure the canvas with staples. This technique is suitable for slow-growing vegetables like carrots and makes them easier to maintain. Photo Depositphotos
  • In the vegetable garden, practice crop rotation. Change the location of your vegetables each year. This disrupts the cycles of specific weeds. Combine this rotation with permanent soil management: green manure, mulching, or successive crops. By diversifying your plantings, you reduce the ecological niches favorable to weeds.

Areas occupied by vegetables and ornamental plants also attract unwanted wild plants. By following a few tips, you can control weeds without chemicals.
