Should we slope garden to aid drainage?
Sorry, another drainage question from me as we prepare for our lawn next month!
I paid a local gardener a one hour consultation fee for some ideas in turning our small, N facing back garden into an "oasis that makes me feel I'm not in inner city London" (my brief).
She suggested that when we have topsoil added, we slope the garden slightly towards the house. This would involve drilling holes at the base of the retaining wall to allow rainwater to run through and into the channel drains of the patio. She also said a slope as you look out of the kitchen window would help with privacy & a sense of cocooning because the garden will be higher at the back.
Is is she right? If so, what gradient would you make? Garden is 9m long. There are pics in my previous posts. Thanks! ????
