Last year was the first year. The forum moderators helped and we had topics and dates arranged for the entire year (2013) by Oct of 2012. While the membership knew we were featuring one plant per month, they didn't know which plants were scheduled for each month. It was a surprise to everyone except the moderators. We were also hoping to not be copied on different sites
This year (2014), we asked our members for recommendations and we scheduled out the whole year by Nov of 2013.
We also published the schedule for everyone to see what was coming up.

The weeks that were repeated from previous years (roses, daylilies)- the topic was a repeat, but the information was new. In other words, different information/articles/ideas were given.
The Plant Weeks have been a lot of fun!
