Concrete Block Retaining Wall
I have a very long concrete block retaining wall that goes from full sun to part shade back to full sun. Last year I planted sweet potato vines in every opening (I think there's over 120) which was kind of expensive even making cuttings and it just took too long to plant every block. It was very pretty though after they grew long enough to cover the wall. Of course, in the winter it's bare. This picture was taken May 4 and you can see it took forever to get the wall covered and this is a little less than half the total length.
Does anyone have any other ideas? Thanks.
