Growing plants in containers has rapidly increased in popularity in the last 15 to 20 years. There are a number of reasons for growing annuals and vegetables in containers. Container gardens are an excellent way to grow vegetables when suitable garden sites are unavailable. Container gardening allows individuals to beautify patios, porches, balconies, the front steps, and other areas around the home. Container gardens also provide individuals with physical limitations an opportunity to grow flowers and vegetables.

Four, short years ago we announced we were watching the spread of another invasive into the state of Iowa. The European paper wasp, Polistes dominula, was first reported in the US in 1978 near Boston, but it was slow to gain our attention until this decade. In August, 2012 we reported it as relatively new to the state. Now, in July, 2016, it seems to be everywhere and in some areas it is the only wasp seen around the house.
