When we moved into our house (Vancouver-Kerrisdale), years ago, we had lots of lawn. Over the years I have gradually removed almost all of the lawn in the backyard. Only a small patch remains. That patch was seeded three years ago with rye grass. Now it is mostly moss and weeds. The area is poorly drained despite having had some work done to amend that before we seeded. It is also shaded for lots of the day by several large trees to the south. Lastly, it is our dog's loo. I don't want more patio or garden area to maintain. I want something lawn-like. I have read about camomile, but don't think that would work due to the damp. I have read about something called Eco-lawn but that doesn't talk about damp soils. Any suggestions would be welcomed.
