Native plantings for the river

Black-eyed Susans and other prairie plants by the river in Minneapolis

Birds, pollinators and other critters depend on native wildflowers and plants for habitat, and even the smallest yard's native plantings can make an impact. (Check out Habitat in the city: the power of the single yard to learn more.)

Many native plants help water quality too. To endure Minnesota's hot summers and deep-freeze winters, prairie grasses like big bluestem grow roots down to 8 feet to reach nutrients and water. These deep roots hold soil in place and allow the earth to absorb far more rain than turfgrass lawn can.

Whether you want to create a whole native garden or just add a few native plants, here are some helpful tips.

Preparing your site

Make sure the area you choose is weed-free. You can remove sod or plan to start fresh by smothering out weeds for a full growing season.

Once your plot is prepped, get plugs from local native plant suppliers. Choose grasses like little bluestem and wildflowers like milkweed that are beneficial to animals and the river alike. (See below for more recommendations.)

If you spent the last year prepping your plot, plant plugs in the spring and water them through any dry periods as they establish.

Fall is also a great time to plant native plants in well-drained, sunny plots. Your autumn planting window usually runs from September through October. Plugs will go dormant, then grow in spring. If you're working on a larger area, or in a less formal garden setting, consider dormant seeding your prepped plot in the late fall, and letting those seeds go through their natural freeze-thaw cycles before germinating in the spring. 

Gardening tips for fall, winter and early spring

Leave last year's leaves where they fall in the fall. Not only do old leaves help retain soil moisture, suppress weeds and provide nutrients, they also protect overwintering bumblebees, which need the insulating leaf layer.

If you're cutting back your garden, leave one to two feet of standing dead stalks to provide nesting cavities for pollinators and other insects. The remaining standing dead material will eventually be hidden by the plants' new growth. We know it's tempting, but don't start your garden work too early in the spring. Wait until night-time temperatures are in the 50s — usually early to mid-May — to allow insects to wake for the season." If you cut stalks, leave them in a stack for a few weeks to allow any nesting insects to emerge.
