What is the best way to stabalise a very dry free draining bank. is it better to use ground cover plants or shrubs

We advise digging plenty of  Levington Organic Blend Farmyard Manure to aid moisture retention and plant with spreading shrubs that will root into the ground as they spread such as Cotoneaster Coral Beauty, C dammeri or Vinca minor or major.

Water well after planting and keep moist until the plants are established.
