Is there a contest for terrariums? if so, how do I enter?
We do not sponsor a contest specifically for terrariums. However, each year in the competitive class entries at the PHS Philadelphia Flower Show, there are terrariums that are entered in competition. Please go to this page on the Flower Show website:
Please read the information on this page, especially the Exhibitor's Guide, which you can download. In going through the guide, I noticed that terrarium classes were there -- see pp. 44-45.
After reading the guide, and if you have additional questions, please contact firstname.lastname@example.org
The 2015 Flower Show will be held February 28 - March 8 at the Pennsylvania Convention Center in Philadelphia.
Hope this helps. Good luck!
