How can I effectively use a solarization tarp to control weeds in my garden?

To effectively use a solarization tarp to control weeds in your garden, first, clear the area of any existing vegetation. Then, spread the tarp over the soil and secure it in place. Leave the tarp in place for 4-6 weeks during the hottest part of the year. The heat from the sun will raise the temperature of the soil, killing weed seeds and roots. After solarization, remove the tarp and plant your desired crops.
