UPDATE: July 2019 –
The new 2020 TPDDL calendar will be out soon. We plan to bring some of those for distribution to the Texas Nursery & Landscape Association EXPO in San Antonio, TX (August 8-10, 2019). There should be some available at the TX A&M AgriLife Extension booth at the Texas State Fair in Dallas this fall.
As for more information of the ailment/symptoms on the calendar, please come back on January 1, 2020 when those factoids will be posted.
