 Book Signing        Pro Tips  

We post Speakers' Pro Tips every evening by 9 pm after the show closes for the day. If you would like to access the SPEAKER PRO TIPS just click on the pink paper icon on the seminar schedule to download and print their Pro Tips, or go to the dropdown menu for a listing of all Speaker Pro Tips. We keep the schedule up for months after the show, so you can access all the Pro Tips as you get back out into the garden.

If you do not see paper symbol, it means that the Speaker didn’t provide a Pro Tips for that seminar.

No ticket refunds in the event of Speaker cancellations.
