Using grass clippings as mulch in vegetable beds can be safe and even effective if certain guidelines are followed.
First, make sure that the grass clippings have not been treated with pesticides or herbicides that harm plants.
Using chemical-free grass clippings is generally safe for your garden beds or lawn.
Secondly, grass clippings may contain weed seeds or other plants that can interfere with vegetable growth.
Allow grass clippings to dry before use to reduce the chance of weed seeds germinating.
Third, freshly cut grass can contain a lot of nitrogen, which will cause a nitrogen imbalance in the soil.
To avoid this, mix the grass clippings with other organic matter.
Also, mown grass can form a dense mat when it decomposes, which can prevent water and air from reaching the soil. Therefore, loosening is useful.
In general, using grass clippings as mulch in vegetable beds is safe as long as you take precautions.
