3 Key Steps to Summer Lawn Care

Click on SUMMER LAWN CARE to learn about the three key steps to a beautiful lawn through the summer.
July Short Story:
Black Spot On Roses

If your roses are starting to look like the picture above, you are among a lot of folks that fight a common fungus disease for roses called "black spot." It occurs at times of high temperatures, high humidity and overhead watering in susceptible plants. Leaves will develop dark spots, turn yellow and fall from the plant. Branches may lose all their leaves, reducing flowering and eventually killing the plant.

The best practices are cultural. Remove and destroy infected leaves and branches. Avoid overhead watering. Drip irrigation works best. Plant roses in places with good sun, plenty of ventilation and good drainage.

Many general-purpose rose dusts and sprays are available that effectively control black spot, as well as powdery mildew, another common rose disease. Always read and follow label directions carefully.

If you prefer not to use chemicals, consider planting cultivars that are resistant to the disease. Your local nursery should have several varieties from which to choose. And, as always, you may call the OSU Extension Office to speak with a Tulsa Master Gardener for more information.
Monthly Pest Alert:
Spider Mites
 
There are two guarantees about the summers in Oklahoma: It will be hot, and there will be spider mites in the garden. 

There are many varieties of spider mites, but the main one in our neck of the woods is the Two-Spotted Mite,  However, it often goes by the name of Red Spider Mite because it is red much of the time. Over their life span, these guys actually range in color from red to green and are the size of the period at the end of this sentence. They thrive when it is hot, dry and dusty. When conditions are ideal, they may produce a new generation every five to six days.

To learn more about these pests that tend to do a lot of damage to our gardens, click on RED SPIDER MITES.
A Few Other Common Pests To Watch Out For This Time Of Year

  • Aphids
  • Army Worms in Turf
  • Bagworms
  • Grasshoppers
  • Squash Bugs, Squash Borers
  • Tomato Hornworms
  • Webworms - possible early generation

Xeriscape: A Low Maintenance Gardening Option
(Without It Looking Like A Desert)

And, once you realize how simple it is and begin implementing it in your landscape and gardens, you can use the term at social gatherings and on social media to astonish your less knowledgeable friends.

Container Gardening: The Options Are Unlimited
 
Planting in containers has transcended years of used metal coffee pots, old tires and wheel barrels. In fact, container planting provides garden enthusiasts an opportunity to take advantage of mirroring large scale landscapes using scaled down replicas. Aside from increased watering requirements over typical flower beds and large-scale maintenance hassles, container gardening presents more shapes, sizes, colors and makes available a mobile-friendly environment.

DID YOU KNOW?

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 Tulsa's Master Gardener programs are self-funded by its own fundraisers, from member donations, and from public donations.

The main Tulsa Master Gardener fundraiser is its Annual Spring Plant Sale that is held each April.  Other fundraisers include the Garden Tour and Garage Sale in June.  And, one of the most important income sources that sometimes gets overlooked are the personal and corporate donations.  These are so important in helping us to meet our financial obligations and we want you to know they are very much appreciated. 

MG Endowment Fund
 
Did you know that we have been around for over three decades, since 1983?  And, we plan to be around for many more decades.  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, the diversity and activity level of our community outreach programs, and our overall financial strength!  
 
So, we are pleased to announce, in partnership with the Tulsa Community Foundation, the Master Gardener Foundation has 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 as well as longer-term estate planning decisions.  Remember, all donations are fully tax deductible! 
 
If you wish to make a tax-deductible donation to help fund the long-term success of the program, click on   TULSA MASTER GARDENER ENDOWMENT FUND.
