Please help me! My husband and I recently moved into a (new to us) home. The lawn is terrible. It is covered in thistle, clover and various other assorted weeds. I'm not even sure where to start !!! It's not a huge yard, but the backyard is in close proximity to our pool, so I want to make sure that any chemicals I use won't somehow make it into the pool water. I really don't want to hire a lawn care service, and I'm not sure whether or not I should wait until next spring or start tackling the problem now. Any advice?
