|Our lawn has many ruts and bumps from moles. I heard that can be helped by using a roller. We have a lot of clay in our dirt so it gets quite hard. I also heard Gypsum helps break that up. In what order should we roll, aerate, fertilize, put on weed killer and re-seed? Help!

|Sounds as though you have your spring gardening chores all lined up. I'd start by aerating the lawn. A core aerator will remove one inch by three inch plugs from the lawn. Leave the plugs on the lawn and they will dissolve in rain or water from the sprinklers. After aerating spread a thin layer of sand or compost over the area and water it in well. The sand or compost plus the soil from the plugs will work their way down into the holes left by the plugs. You can then overseed your entire lawn. After you have mowed the lawn 2-3 times you can feed or use a weed and feed product to address the weeds. You'll probably not need to use gypsum after you've aerated and spread compost or sand. Your soil will drain much better after aerating. Best wishes with your lawn!
