agree with Berghill....make sure all grass weeds are eradicated
I think your idea is great. I love growing grasses
for stipas of all types, fescues, helictotrichon, hordeums and elymus no preparation is necessary on your warm slope. Sharp drainage and sun is perfect. A word for stipa gigantea.....a real stunner all summer. Outdoes most everything else esp with late sunshine behind the flowers
other grasses need more prep....miscanthus and calamagrostis need decent soil so add compost to the soil mix. So too with pennisetums
deschampsias, carex, uncinias, hackonechloas and bowles golden grass need extra water holding material in your site.
the addition of coloured foliage plants like heucheras can add a great deal to a grass border as will verbena bonariensis there.
Will look great nige55
p.s. For winter arrhenatherum bulbosum is wonderful. White foliage brightens a shady garden as well as a sunny one.
