THE ARBOR DOCTOR

Arbor Doctor Ron Rothhaas will be speaking this year at the Dayton, OH Home and Garden Show at the Dayton, OH Convention Center.   

Ron will be speaking on the subject of “What does bad weather do to your plants?”, a timely topic with the heat waves and droughts of recent years.  Many of our trees are suffering, and understanding how weather interacts with other environmental factors can help you to do a better job managing the health of your landscape. 

Ron’s presentation will take place on Stage 2 at 3:00 PM, March 22, 2013.

Arbor Doctor Ron Rothhaas is scheduled to appear this Saturday, March 2, 2013, on In The Garden with Ron Wilson on 550 AM, WKRC radio.  Ron will appear from 6:30 AM to 9:00 AM as a member of a panel of experts including host Ron Wilson; Steve Foltz, Director of Horticulture at the Cincinnati Zoo & Botanical Garden; and respected horticulturist Liz Jacobs from Natorp’s, Inc.

In advance of the show, Ron Wilson remarked, “I thought it would be a great idea to have a panel discussion about trees, and of course the three of you came to mind.  You all three represent different aspects of the industry, and I value (highly) all three of your opinions and expertise!”

Ron Rothhaas remarked, “It is an honor to be asked to appear with such highly credentialed colleagues.  Hopefully, I can avoid my daughter’s flu bug and be able to be present on Saturday!”  Ron is a 1988 graduate of The Ohio State University,  a 1985 graduate of Cincinnati Technical and Community College, an ISA Certified Arborist and member of the American Society of Consulting Arborists.  He has worked in the horticultural field for three decades.

About 90% of the time, an arborist trained in tree risk assessment could foresee damage such as that seen in this video.  To be clear, without having seen this tree one cannot comment on its pre-failure condition:  https://www.youtube.com/watch?feature=player_embedded&v=NnIodcwdPM0

Myths such as this tie our present to the distant past when nature did, indeed, influence our lives. It is the day that the Groundhog comes out of his hole after a long winter sleep to look for his shadow.  Read the article here>>>

Evidence is increasing from multiple scientific fields that exposure to the natural environment can improve human health.  Read more here>>>
