Poison Ivy and Poison Oak - A Refresher Course

                      Poison Ivy Vine                                                  Poison Oak

Both Poison Ivy and Poison Oak are commonly found in Oklahoma.  Each of these plants contains a toxic compound called "Urushiol" which acts as an irritant to the skin and mucus membrane (eyes, nose, and mouth).  This toxin is found in all parts of the plant, roots, leaves, and stem and is present even in winter.

Fall Garden Planning in July?      Yes, It Is Time To Do So!

For those of us who love the taste of fresh fruits and vegetables, gardening is a  year-round activity.  The fall gardening season, which begins around July 15th, can actually produce some of the tastiest garden vegetables in Northeast Oklahoma, as we typically have warm sunny days followed by cool nights later in the season.  Under these very favorable growing conditions, plant metabolism slows down which helps them produce high quality and tasty vegetables.   Click  HERE  to read more about Fall Gardening.


The Tulsa Master Gardener Foundation is a 501 (c) (3) organization.  As such, it receives no city, state or federal funding for its Tulsa community outreach programs. In fact, the majority of Tulsa's Master Gardener programs are self-funded by its members. We need your help..

Tulsa Master Gardener's own fundraisers make up most of the income to cover expenses. More specifically, a significant portion comes from the Tulsa Master Gardener Annual Spring Plant Sale that is held each April. Other fundraisers include the Garden Tour (June) and "Garage Sales" that occur from time to time. Finally, one of the most important income sources that sometimes gets overlooked are the personal and corporate donations.  These are so important in helping to meet our financial obligations and we want you to know they are very much appreciated. 

Donations for this month include:
