Mowing the Lawn
Lawns across Iowa have turned a beautiful, dark green in the last few weeks. Proper mowing practices over the next several months will help keep the lawn attractive and healthy.
Emerald Ash Borer Treatment Times
Emerald ash borer (EAB) the destructive, invasive insect pest that attacks and kills ash trees has been confirmed in 45 of Iowa's counties. Iowans who want to protect their ash trees from attack can use one of several insecticide application techniques to put specially-formulated insecticides into the tree to kill EAB adults and larvae. Treatment is warranted only to valuable and healthy ash trees within 15 miles of a known infestation of EAB.
Container Gardening
A traditional home garden is a popular way to grow vegetables, but it’s far from the only way. Growing vegetable plants in containers can also produce a bountiful crop, although care must be taken to ensure meaningful growth.
