Here is a link to a website with a native plant database maintained by the state to help people find plants that match their conditions. If you want trees on the slope, I would choose hearty natives rather than ornamental trees like Japanese maple. Also, the existing seed bank of weed seeds will get covered by decaying wood chips and will be denied the light they need to germinate. As the soil changes character, it will become unfavorable to many weeds, and it will be easy to kill any that get a foothold. As the wood chips decay into the soil, keep replacing them because the decayed wood will bring in earthworms and other soil microbes. This will deny light to the weed seeds and make it difficult for weeds to take hold. To suppress the weeds, I recommend you cut down what is there and put a layer of mulch 4-6 inches thick of undyed wood chips. Even our native hay scented ferns which grow matted roots and release chemicals to suppress other plants are invaded by goldenrod and wild morning glory to name a few. The soil is full of weed seeds that have blown in or come from weeds that have gone to seed. If you would like some photos of the area I can take some after work someday.Īnything you plant on your slope will still need weeding and maintenance.
I need some ideas on how to kill the weeds at first, then need ideas on what to plant or place on the slope to keep the weeds from coming back.Īny help that you can give me would be appreciated. We have planted a few trees on the hillside which have established themselves pretty good but the weeds are just out of control. At least once a summer I have to take a weekend or two just to weed the hillside which has many different weeds including poison ivy which I am highly reactive to.
The majority of our soil is either shale or clay so the sloped area has no ground cover. The remaining earth was used to flatten the area around the leech bed and pushed towards the neighbors property which created the slope. I'm told by the neighbor that when the house was in construction the contractor cut into the existing native slope for the house foundation and installed a septic system and leech bed next to the house. The slope is about 50-60 degrees at its steepest. Approximately 150' long and 10' high at the highest point. I have a steep slope on one side of my yard.
