 Yeah, to fertilize correctly. Right. In other words, you might not be giving it the stuff that it needs and it won't grow. Yeah, you're working blind. Now, the other thing to keep in mind is that the best time to do this is not the beginning of summer. The best time to do this is in the fall when it's a little cooler out because even if you did everything right and it started to grow, the intense heat that follows a month or two down the line will burn it out and kind of ruin all the good work that you did.
