The Secret Triwizard Challenge

You cut open the apple with a small Diffindo spell and take out the seeds. Then, you dig a hole at the bank of the pool, place the seeds in, and cover the hole with dirt, giving it a loving pat.
Nothing happens. The seeds don't appear to be magical, and you don't remember the charm to grow plants quicker. All you have now is a very violated apple. You go to pick another one.
As soon as the apple snaps from the branch, the ground beneath you rumbles. Roots from the trees burst from the ground, wrap around you, and force you to the ground. You must have taken more than you need. You should have obeyed the sign!
Your wand slips out of your hand. You are truly and thoroughly stuck.
------
You can find no way out. The next morning, the professors check on their challenges within the maze and find you, tired and dehydrated, in the clutches of the tree. They get you out, but are furious that you went into the maze. Frankly, you'll probably be expelled. But that's nothing in comparison to the fact that you lost the race. YOU LOSE!
