We've fertilized & verified watering but our lawn has been dying starting last summer & now all but gone now. Winter rye grew fabulously. What's going on?

You probably have a combination of bermuda and perennial rye grass. The bermuda greens up in April when the weather gets warm and then begins to go dormant in October when the weather cools. At that time the perennial rye will come out of its summer dormancy and remain green from October through April. Ryegrass usually needs to be reseeded every few years and sometimes bermuda needs a little boost, too. In general, overseed with rye in October and overseed with bermuda in April. At this point there's not much you can do to green up your lawn so why not take the opportunity to aerate your lawn and check to make sure you don't have an overabundance of thatch. A core aerator will take one inch by three inch long plugs out of the lawn. Leave the plugs to dissolve in rainwater or water from the sprinkler. After aerating, spread a thin layer of compost or sand over the lawn. This will work its way down into the holes and provide a place for water to collect and percolate down and will also provide healthy places for the roots of your turf to explore and grow into. Reducing compaction by aerating is one of the best ways to revive your lawn. Hope this information is helpful.
