Hello, I have a new house and have finally decided to decorate the backyard. I noticed that when it rains, water usually does not drain very well and I have a feeling that in that situation my plants may not do that well. I do have some grass growing there thought I think its mostly Crab grass. The options I have been presented with are as follows: A) Level the yard with Top soil and then sprinkle grass seeds or lay pre-grown grass. B) Make a small ditch like drain that run out of the yard to the street and have paver sand on the base of it with river pebbles on the top C) My parents favorite choice, dont do anything! Any suggestion on which one to go with?
