I'm needing some advise for my monstera. I got it as a Baby with 2 leaves and it's grown so beautifully. It just got it's 13th leaf. It's growing horizontal and I'm running out of room for it. I'd like it see if I can get it to go more vertical. Because it's already horizontal how do I get it to climb? The leaves are a good 1 to 1.5 feet outside the pot. Do I just tie it up? Or would that break it?

Second question is if I propagate it will it continue to grow where I cut it? All 13 leaves come from the same branch so if I cut the top one to propagate I just want to make sure It will continue to grow from where I cut it on the mother plant.

And 3rd question, can I plant my propagated leaves into the same pot to give it a more full appearance?

And lastly, how big of a lot does the plant need?

Thanks!
