morpheuspa...there is a clover that has grown over the entire hill for now, then the ugly thick weeds will start to grow. you are right about the mulch, nothing was stay unfortunately. I would not minding planting if nothing had grown already :) Thank you for your feedback.

Maybe clear the deck once with Round Up and then plant? There are certainly tons of other plants that will effectively hold soil on a slope, are attractive, and don't require maintenance. Pachysandra comes to mind, although it prefers shadier conditions and plenty of moisture. Daylily likes full sun and doesn't care about soil conditions or watering. Ajuga is much shorter, blooms prettily, is indifferent to soil quality or water, but can be a little invasive if not taken care of.

Some that are great, like yellow archangel, I don't recommend due to their invasive nature. Some states have them listed as a noxious weed.

The area is approx 40-50 ft by 100 ft.. planting bulbs is not an option for me.. lol I will look at the other flowers mentioned. :)

That is quite large! Daylilies are tubers, however, and spread quite nicely on their own. Not many are required, and you can let them spread while also using something else to temporarily dominate the area.

With an area that large, I might look into wildflower mix. It's in a handy can, so you can just shake and water and stand back. It would require re-doing yearly, I think, as I'm not sure how many of those are going to re-seed themselves spontaneously, and would require a cleanup at frost when the plants die back.

maybe cut and fill large strips of the landscape at intervals? Then you can plant small trees on the flat bits and would be safer for hubby to spray the slopes

While a natural vegetation is always best for steep slopes, have you considered a mulch mat? There is a nonwoven mat made from industrial hemp that is all natural, easy to install, and nice looking. Because it's a mat that is anchored down, it won't slide down the hill. It'll slowly biodegrade over time. Combining it with some plantings would be a cost effective solution; over time, as the mats degrade, the vegetation can take over. Like any mulch product, though, you have to like the looks of it. Here's the website:

Outside of the mulch, I'd agree with morpheuspa that a wildflower mix would walk the lines between aesthetics, effectiveness, and labor.

Asphalt or cement will require no maintenance and will not let ANY weeds sprout unless there are cracks. I'm considering this for part of my yard. :)

i need to get rid of all the Weeds on my Moms Steep Hill in her back yard Hill !!! They are a Pain for myself just to get up there & Pull out , plus i don't want to hurt my Back !! What would you Suggest , yes i pull the weeds but there are AFRICAN DAISEYS mixed in & they are Runners too. So any Advice !!! Thanks Lisa .

Spraying kills the roots that are holding your soil together. Do that, and you will have erosion and gullies....Clover is excellent....Plant evergreens at the top of the slope or put a fence, so you dont care whats behind it.

What about terracing?
