If you are going to plant a hedge or a massive amount of Lavender, make sure the ground is cleared of weeds. Solarization works to remove not only tenacious weeds, but also kills weed seeds. Small Lavender plants cannot compete with aggressive weeds, and weeding after they are planted can be a huge hassle. Weeding often becomes such a chore that Lavenders are overrun and eventually die in a neglected field.
