The annual Tulsa Master Gardener Garden Tour is back on for 2021. We have five outstanding homes on display plus the Demonstration Garden around the Tulsa County Extension Office. In part because we were not able to have this event last year, Master Gardeners have been working extra hard to make this year's event better than ever.

The event will be held the first weekend in June, on Saturday June 5th from 9-5 and on Sunday June 6th from 11-5. Our organization is self-funded and this event represents a major fundraiser for the Tulsa Master Gardeners. Master Gardeners will be on hand to answer all of your questions at all locations. So, plan on coming out to support us and see some very beautiful landscape displays. A great way to get some new design ideas!

This month’s article completes our discussion of compost tea.

As you may already know, brewing compost tea is not a new idea. Researchers have found evidence that early Roman, Greek, and Egyptian farmers were making tea using brewing methods that probably involved a bucket, compost or manure, water, and occasional stirring. Such methods, unfortunately, create a high probability of anaerobic conditions developing. Therefore, these methods are discouraged and brewing Actively Aerated Compost Tea (AACT) that uses fully decomposed hot compost, as well as an aeration system, is recommended. This is the method described in last month’s article.

While there are any number of enthusiasts painting compost tea as a panacea for all your garden ills, there are many (including university and extension center) websites that paint a different picture. Who’s right is up for debate. We report - you decide . . . by clicking on COMPOST TEA: GOOD OR BAD?

Want to learn more about composting? Here are a few suggestions:

During spring, when nighttime temperatures remain a consistent 60 degrees Fahrenheit or higher, it is safe to transition your houseplants outdoors. As you make the transition, start by placing your plants next to the house in a shaded area and gradually move them to brighter locations, over the course of five to seven days, to avoid shock. 
But, that's just the beginning. Click on MOVING PLANTS OUTDOORS to learn more best practices of moving those treasured indoor plants out to nature.
Lace bugs attack azaleas, some rhododendrons, and many ornamental shrubs. They feed mainly on the undersides of the leaves, leaving the top of the leaf with white to yellow stippling or flecking. Heavy lace bug feeding on azaleas can reduce plant vigor and flowering and affects the overall look of the plant.

Because most lacebugs overwinter as eggs and hatch in the early spring, that is a good time to control them before they do hatch. Click on LACE BUGS to find out more about identifying, monitoring, and controlling these pesky little bugs.
Spring is officially here and the Bermudagrass is starting to green up in spite of the unseasonably cold weather that we have had lately. If you are seeing dead, brown patches amongst the lovely spring green of your Bermudagrass lawn, you may have a case of Spring Dead Spot. It usually appears in overly fertilized lawns, so the “more is not better” rule of fertilizer rule definitely applies here.

For more information on the causes of it, how to be proactive in avoiding it, and how to manage it once it appears, click on SPRING DEAD SPOT.
DESIGNING: In February we featured Part One of a four-part series on Designing, Building, Planting, and Maintaining a vegetable / herb garden. It focused on the planning and designing phase. If you missed it or would like to review such, click on PART 1.

BUILDING: In March, we covered the building phase of a new vegetable garden, including in-ground, forms of raised bed and container layouts, as well as soil types and preparation for the new garden. If you missed it or would like to review such, click on PART 2.

PLANTING: Last month we covered the planting phase of a new vegetable garden, including temperature and frost tolerance, planting times for your chosen vegetables, arranging plants in the garden, and other planting tips. If you missed it, or would like to review such, click on PART 3.

Part 4 is just below the pictures.

So, welcome to the fourth installment of our four-part vegetable gardening series. Now that your project garden is planted, be ready to enjoy the next phase of nurturing and maintaining by clicking on MAINTAINING THAT GARDEN to learn about some best practices to stay ahead of problems and issues. We hope this series has helped get some folks out and digging. Happy gardening!
Think that you have to have a large space to grow vegetables? Think again . . . you do not. You may be amazed how much you can grow in a small space, called Square Foot Gardening, if proper planning is done ahead of time.

Popularized by Mel Bartholomew on PBS Television, Square foot gardening is a technique for growing a variety of flowers, vegetables and herbs in a small space. Click on SQUARE FOOT GARDENING to learn how to properly do this unique gardening. 

Clearly, we had one of the coldest winters in many years. It will have killed many newly established plantings but also some of the more mature shrubs and trees as well. While it's too late to do anything about it now, here are some tips you can employ in the future to protect your landscape from cold winter damage:

  • Avoid late season (summer) fertilization as it stimulates late season growth that is most susceptible to freeze kill

  • Mulch well to conserve moisture and to insulate roots

  • Water shrubs and trees extremely well in the fall to prepare them for winter

  • Erect screens or other wind blocks around shrubs and trees in the most windy areas
By far, tomatoes are almost everyone's favorite vegetable (actually, it's a fruit). We love to eat them but, given our sometimes corky weather patterns in Oklahoma, problems do occur. One of the most common problems is one called Blossom End Rot.

It is due to a lack of calcium but it may not be a soil nutrient issue. Click on BLOSSOM END ROT to learn more about this disease and ways to potentially prevent it.

Since 1983, the Tulsa Master Gardeners have been serving the public by offering research-based horticultural information to residents of Tulsa and the surrounding area. 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
The Tulsa Master Gardeners have been around for over three decades and we plan to be around for many more decades. Furthermore, we are considered one of the top five Master Gardener county programs in the entire nation. We are because of the size of our Foundation membership, the number, diversity and activity level of our various 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!
