Weeds?

Do not leave bare soil:

• mulches (bark, plant fibres, leaves, crushed straw, etc.) inhibits the growth of weeds and prevents soil compaction and drying,
• cover crops at the foot of hedges, trees and roses, crowd out weeds while providing a non-invasive decor.

Manually uproot weeds before they become too invasive.

Use boiling water on paving and gravel.

Lawns:

• dethatch, anti-moss products are useless because they do not tackle the causes, and sometimes even exacerbate them (iron sulphate),
• mowing longer, 5 or 6 cm in height, keeps the grass in good condition above the rosettes of the large invasive plants – plantains, dandelion – and keeps the flowers – daisies, violets, speedwell – which are pretty and favourable to insects.
   

Vegetable patches:

• plant in rows, not on the fly,
• do not use cutting tools (spade, garden tractor) in order not to split the roots and promote the dispersion of invasive plants (couch grass, nettles, bindweed, etc.), use a toothed spade or a fork.
