Application of pesticides is forbidden at all times on residential land throughout the territory.

Encourage biodiversity in your lawn by using a variety of grasses and plants and be tolerant of insects, which are mostly useful.

For an ecological lawn

  • Rake and aerate (spring and fall) when the soil is dry.
  • Spread compost (less than 1 cm) and use a rake, upside-down, to make it penetrate.
  • Sow some dwarf white clover, which helps grasses to absorb nitrogen.
  • Mow, with a mower set at a height of 8 to 10 cm (5 cm earlier in spring and late in fall) and leave the short clipping on the lawn. They provide nutrition and better heat resistance, as well as supporting the lawn against dandelions and white grubs.
  • Remove intrusive weeds (by digging up the roots) as required. Sow the denuded ground immediately with a mixture of grasses and compost.
  • Plant shrubs and trees. The forest absorbs about 90% of rainwater; the lawn, however, absorbs barely 50%, with the rest ending up, complete with its contaminants, in our lakes and rivers. A tree will absorb about 250 kg of carbon dioxide in its lifetime and will give off part of the oxygen necessary to our lives.
