Willowherb and bindweed are examples of common deep root weeds. Their root system can spread and plant tightly into the ground. To remove this type of weed, gardeners need to work with individual weeds. First, locate the puller at the base right above the soil line. Then, give the base a firm hold and twist it to loosen up the root.  Twisting also avoids breaking the root while the gardener is pulling the weed up. After each twist, pull the weed up steadily. Repeat the process until the entire root is pulled out. After each treatment session, use mulch to cover the garden. Mulch protects the garden by preventing weeds from getting sunlight.
