NEW!  Tulsa Master Gardener Endowment Fund

The Tulsa Master Gardener Foundation is a 501(c)(3) organization.  Not only are we non-profit, we are also completely self funded.  We do not receive any funding from federal, state, or local authorities . . .nor from OSU.   Essentially, all of our funding comes from a combination of three sources:

1) Our own Master Gardener fundraiser programs (Spring Plant Sale, June Garden Tour, etc.)
2) Our generous public corporate and private donations
3) Our own generous Master Gardener donations

These donations keep our multitude of Master Gardener Outreach Programs funded and functioning year to year.  We sincerely thank you for your previous donations and hope that you remember us in the future.

Did you know that we have been around for over three decades , since 1983?  And, we plan to be around for many more decades to come.   Did you know that we are one of the top five Master Gardener county programs in the entire nation?   We are, indeed, because of the size of our Foundation membership as well as the diversity and activity level of our outreach programs!  

So, we are pleased to announce, in partnership with the Tulsa Community Foundation, the Master Gardener Foundation has now established an Endowment Fund to ensure our long-term financial strength.  Our plans are to build this fund for many years before making any withdrawals from it.  Please consider us as you make your annual gift giving and estate planning decisions.  Remember, all donations are fully tax deductible! 

If you wish to make a tax-deductible donation to help the long-term success of the program, click on TULSA MASTER GARDENER ENDOWMENT FUND.

If you wish to make a tax-deductible donation to help fund our annual expenses, click on TULSA MASTER GARDENER AGENCY FUND.

We thank you for having been such faithful contributors both in the past and in advance for your future consideration and participation!

Fall Fescue Lawns

You may have noticed that lawns in general are doing better this year than last year, especially fescue lawns. Ambient temperature and moisture levels have a lot to do with this.  To find out more about why and how to make your lawn the best it can be, click  HERE .
Fall Gardening - What to do NOW!
Some of the best quality garden vegetables in Oklahoma are produced and harvested during the fall season when warm, sunny days are followed by cool, humid nights.  Under these conditions, plant soil metabolism is low.  Therefore, more of the food manufactured by the plant becomes a high quality vegetable product.  For more information on how to make your fall garden a big success, click  HERE.
Mushrooms - They're Everywhere!  Why?

We have certainly had our share of mushroom and Fairy Ring outbreak this year.  Left unattended, not only are they unsightly but can be damaging to an otherwise nice lawn.   Click  HERE to read further about what causes mushrooms and Fairy Rings to appear and what to do about them before they damage your turf.
Dividing Iris's - Let's Do It Now!

Iris's, like a lot of perennials, should be divided every few years to enhance their looks and prevent overcrowding.  They should be divided opposite of their flowering season.  Divide spring-flowering perennials in the fall; Divide fall-flowering perennials in the spring.  How to tell when your plants need to be divided and how to do so,  READ ON.

"The Dirt On Soil"
What To Do About Challenging Soil Conditions

Some call it dirt, some call it soil . . . and some have other unmentionable names for that stuff beneath our feet, especially here in Oklahoma.  So, what exactly is soil, why is it so important, and how can challenging soils be improved so that our plants will grow and thrive?  If you wish to know more, you can access a brief document on the subject followed by a host of OSU fact sheets and other reference materials.  J ust  CLICK HERE. 

Rainwater Harvesting and
How To Make A Rain Barrel

Rainwater harvesting is the process of capturing, channeling, and storing rainwater for later use. Methods of harvesting rain date back more than 4,000 years.  Today, rainwater harvesting systems can be implemented at home by almost anyone with a little bit of planning and effort.  To find out more about these systems and how to make a rain barrel, CLICK HERE.


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:
