When the newest leaf on my giant bird of paradise started to unfurl, I (perhaps foolishly) decided to help it by pushing the edges past the obstacles created by the existing stems. Now the leaf is fully unfurled, but the stem is too short; instead of arching over the previous leaf, it sticks straight up and has hardly any space for another leaf to bud. I'm afraid I may have caused the stem to stop growing prematurely by causing the leaf to unfurl too soon, and I wonder if there's anything I can to remedy the situation. This is a plant I rescued a couple of years ago and I'd hate to think I ruined it out of stupidity. Any help would be very much appreciated.
