In the far corner of my garden it is shady & wet (large trees behind garden,
no sunshine), the soil is clay and my lawn has died (due to the wet?) Has
anybody got any ideas how to help my grass to grow?

What if I where to plant some thirsty plants in the area, would this help?

By the way, I am not an accomplished garderner, but I think I am going to
give my garden a good go this year.

Thanx.
