Is the cake layers all the same? I did a flower pot, you can see it in my pics, but pay no attention to the flowers please A little different than yours tho. I had my top layer bigger than the bottoms so that it stuck out just a bit to make that top ring. Fill free to PM me if you need to. I am definately not an expert, but I learn alot with it.
I just started wilton class 5 last night and we made a flower pot and the top is a lot larger than the bottom like a upside down cone.Then the top rim goes above the end of the top cake edge to hold all of your dirt in.Good luck
I would use a bigger top cake or you could carve it to make the flower pot shape.
I think you did a very good job, but my personal opinion is that for as big (wide) as it is, it should be quite a bit taller. I also agree with the others in making the top layer a little bigger the others to create the lip around the top of the pot.
I tried making the top one a bigger around layer the first time I did a flower pot but the top layer just fell apart. Do you put a support just under that top layer then?
Yes you could have the top layer on a cardboard cake circle cut to size.
My only flower pot experience is reading the article here, which I'm sure you've seen but on some extreme off-chance that you hadn't.... http://www.cakecentral.com/article46-Step-By-Step-3D-Cake-Sculpting-Baby-in-a-Flower-Pot.html
If you fondant cover the cake upside down like that, how long do you let it dry? I tried that one of the first times too, maybe I didn't let it dry long enough but once I flipped it over, it kept peeling away. Lol, that was a fun night.
