Hi,

Just want a spot of advice.
My soil is very heavy clay and waterlogs readily in certain areas of the garden.
My plan is to grow some climbers (clematis/jasmine) up a trellis on my shed (south/west facing). Unfortunately the area is an aforementioned soggy one (the subsoil was like muddy clay). I have dug down about a foot and replaced with compost and topsoil but this hasne helped.
So I figure the best way, is to go upwards.
I intend to create a small raised border/bed for my climbers and some annuals/trailing plants etc. Ill raise it about 9, anything higher will put too much soil against the shed.

Do I need to do anything else to my muddy subsoil, or will this be sufficient for plants such as clematis (armandi and a late flowering one)
I know they like free drainage.

Also is it worth lining the shed side of the bed.

Cheers

Ed
