 It doesn't spread. It doesn't go everywhere. And then on top of that, if you have it outside, I want you to keep it where it's going to have bright, indirect sunlight. Don't place it in a shady, shady spot because we want the sun but not too direct. So obviously we're looking for a bit of shade. I'm talking don't leave it in the shade all day. That's not something we want to do here.
