How can I effectively protect my garden from weeds and pests using a plant tarp?

To effectively protect your garden from weeds and pests using a plant tarp, you can lay the tarp over the soil before planting to prevent weed growth. Make sure to secure the edges of the tarp to keep it in place. Additionally, you can use the tarp to cover plants at night to protect them from pests. Regularly check under the tarp for any signs of pests or weeds and address them promptly.
