Hi Alex. As your Scheff grows taller, it should sprout out more branches. If is seems like it won't branch, you can always pinch the top main trunk. Good luck, Toni

Thanks Toni!

Also, if I wanted the plant to get aerial roots, would a plastic bag over it help retain humidity and promote aerial rooting?

Hi Alex, Sorry I haven't been here until today..Aerial roots develop with age..If you were to grow your Scheff as a bonsai, they (might) grow faster than if grown in a large container..Do you plan on growing your Scheff as a bonsai? Toni

Oh its fine dont worry about it.. your the only person who actually responded in the first place so thank you for that.

I didnt plan as growing it as a bonsai, but maybe I will. Its still in a weird pomegranate juice container where I rooted it, but when I pot it up should I maybe get a really shallow dish to put it in to promote the aerial rooting?

Thanks Again

Alex, check out www.wikipedia.com In the search box, type in 'aerial root' The second pic is of a bonsai scheff arbor/w/aerial roots.
To grow as a bonsai, it should be kept in a small container..as plant matures transfer to a bonsai pot. Toni
