Spring is on its way, but is not here yet so don’t be too eager to get your lawn growing. Trying to force growth in lawns by applying fertilizer too early often results in disease problems and cold damage. Instead of fertilization, the big focus for lawns in early spring is weed control. Now is the time to treat lawns to kill weeds like henbit (left), whose bright purple flowers are just staring to open, and burrweed, whose sharp, prickly seedpods ripen later in spring, causing pain for pets and people. Many products are currently available in garden centers for weed control, but they should be used carefully. Some will hurt your lawn more than they will help it.
