One thing pollinators have going for them is that most species can take advantage of habitat almost anywhere it is provided. This means that any landowner, whether they own a lot that can be measured in square feet or one that is many acres, can create habitat for pollinators.
The main characteristics a good pollinator garden needs to have are: 1) flowering plants in a 2) sunny spot that 3) bloom from Spring through Fall. We would also recommend, if possible, to consider using predominantly plant species that are native to Iowa. There are many species to choose from and they are adapted to Iowa’s environment. Most are perennials or good self-seeders (less maintenance!) and our native pollinators love them.
A pollinator garden can be as formal or as “wild” as you would like. If planting a smaller area that you want to look more formal, it is likely best to plant plugs of prairie species rather than trying to spread seed. If planting a larger area and a more natural look is okay, a mix diverse in flowering prairie species will be more economical, though it will take a bit longer (2-3 years) and a little more maintenance (mowing) before it starts looking its best.
The following pdf includes a more detailed description of how to create monarch and pollinator habitat, both large and small, and includes a species list and links to more resources.

For larger areas, if you'd like some assistance, landowners can contact the DNR Wildlife Bureau’s Private Lands biologists for advice and assistance. The DNR also has staff that can work with private landowners and you will find a great guide to shrubs and trees that are good for pollinators on their webpage.
