Cutting from a tree

I took a cutting from a tree about March time (not from my garden) to see if I could do it. And I planted it in a pot and then put a plastic drinks bottle which I cut in half on top of it. It's starting to grow new growth (leaves) is this a good sign or would this happen anyway? (Even if it wasn't going to grow roots).

I hope it grows roots!

 

Update: It has roots!! First attempt, as well.

 

Nice one, out of interest what tree was it?, normally trees are propergated by hardwood cuttings in the winter :thumb:

 

No idea! I'll take a picture of it later.

 

Congratulations Kyle, it's a great feeling when the smallest of challenges pay off!
