    Adrienne, Good Morning :) I have a few weblinks for you to peruse that are informative and, I hope, useful to you. As one of the links says, you want to make sure you anchor the soil (since havey clay is prone to slippage when it gets wet), and the best way to do that is with warious plants that send their roots down to differing depths in the soil. Heavy clay needs to be amended somewhat in order for it to be a bit easier for plants to get their roots deep into the soil and hold on to it. One of the links below lists a long line of plants and the zones they grow well in, plus gives a link to a site about that plant.

    I see the news on television where there are fires and floods and mudslides and each time I see these things I pray for all the people living in those areas.

    I do pray that you and those you love are kept safe, and that this information is helpful to you, and to anyone who read it. Thanks for using Hometalk :)

    Have you ever considered a rain garden or two to help slow the water running downhill by catching it in its basin and allowing the plants in the rain garden to utilize some of the water while it is being absorbed and distributed into the ground? I think it would be something to seriously consider :

    I have seen ground cover roses on sloped places like yours. They were hybridized with slopes and easy care in mind. Just amend the soil in the hole where you plant anything as clay is tough for plants to grow in. A wonderful ground cover is kikinkakik; the star creepers (white star or blue), and Angelina are lovely too.


    All of the above will hold the soil from slipping. And require very low maintainence. You have a great start alread, it looks great!

    I too have heavy clay soil plus I needed something very cheap. I planted spider plants that I started in good soil to get the roots growing. Asking for 'babies' from neighbors and friends plants I had enough to plant mine about10 inches apart in a diamond pattern. It's been a year and I have my whole hillside filled in just by tucking new starts into the blank areas. I watered pretty well the first year but have cut back over the summer (I'm in So. California) and everyone is happy. We had some real down pours and no soil erosion.

    Terracing would look amazing. Use rocks to define layers and add trailing plants that spill over the rocks.

    Try Gooseneck. It spreads root to help stop erosion. It grows quickly and I have never seen anywhere it won't grow

    For erosion control,try perennial vinca (evergreen),creeping Jenny,liriope,and grasses. Our master gardener class helped with these plants next to a creek that was eroding.

    You might ask your county's cooperative extension on what would work well.
