Small hill in backyard help #871159

Asked June 02, 2024, 2:06 PM EDT

Hi, we have a small but steep hill in the backyard near our property line. Currently, there is a mix of plants like hostas, small trees/shrubs, and grasses or other small plants with a solid layer of mulch. The previous owners would just get fresh mulch 1x/yr. We are interested in advice on how to improve this hill in a few ways: - erosion control - low maintenance (very difficult to climb up and down hill, such as clearing dead hosta leaves in fall or to weed / remove invasives) - hardy (we have a dog that often goes on the hill) - attractive - native plants and pollinator friendly - accessible ('steps' on the side are currently buried under dirt and mulch) - reduced risk of ticks (dog) Our current strategy has been to remove all invasives, remove old/moldy mulch, lay down black plastic to kill remaining weeds and invasives (cutting holes or leaving space for plants we want to keep), and then lay new soil and seeds for bee lawn this fall. Around the edge we were going to place mulch to keep a barrier from the fence in hopes of reducing ticks. We were also going to try to make a more established/firm path up the sides and on top (existing stone paths are buried)

Thank you for your question and pictures. You have a very attractive back yard area with the stone boulders and variety of plant material. I can answer your plant questions, but as far as stone paths and erosion control on a slope, you will need to contact a landscaping firm. It sounds like you are doing everything right in your plan to remove invasives, place black plastic down for weed control (called solarization), and plant a bee lawn. Here is a resource for planting a bee lawn from Extension:

You will want to plant natives and other plant material that survives on a hill.  Remember, there are many shrubs and small trees that attract pollinators. This excellent publication titled The Best Plants for 30 Tough Sites, from the U of MN, has a section about planting on steep slopes:

Wood ticks are generally found in wooded areas or in tall grasses. Mulching in the areas around the plants is your best solution for ticks and also for weeds that may take over your area. You are on your way to adding to and creating a nice backyard space.
