Wheat Grass and Drowning Seeds

We've been making small strides in the garden. We have many seeds growing -- tomatoes, basil, carrots, pumpkin, squash, and flowers (don't even really know what kinds) -- yet very few seedlings. May have something to do with the fascinating water bottle spray... We also are trying to grow wheat grass. We'll see how that goes. Can't really go wrong when you're playing in dirt!
