Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

Title: Eradiacation of johnsongrass along roadways
Answered by: Nan Hampton

QUESTION:

What does latest research show on eradication of Johnsongrass along roadways?

ANSWER:

It seems that the prescribed methods of controlling Sorghum halepense (Johnsongrass) still include torching and burning, plowing or digging it out, mowing and grazing and/or herbicides. The Nature Conservancy Element Stewardship Abstract for Sorghum halepense offers more detail about timing and techniques of the treatment. The National Invasive Species Information Center (NISIC) page for Johnsongrass pulls together a list of publications and links to ongoing research dealing with the problem. This includes links to various states control plans and academic research programs. You can also see titles of research papers (from 1959 to the present) relating to the eradication of Johnsongrass in Sorghum halepense Article Citation Search - AGRICOLA Database from the USDA. Johnsongrass is still a problem and is still difficult to eradicate or control. No one has come up with an easy foolproof method so far.
