Grow and Graze, Lecture and Lunch March 19

March 19, 2019

Tatsoi seeds were sown in January. Look at it now!

Have you ever grown Tatsoi? If not, you may want to give it a try. Our Salad Gardens class on March 19th will introduce you to this sassy little Asian green that delivers a unique flavor experience. Following the class, join us for lunch at the salad garden buffet where Tatsoi will be one of our “featured” greens.

After lunch, take a stroll through our edible landscape where you’ll find Tatsoi growing in abundance around the bay laurel tree. Our volunteers have become big fans of this small, spoon-shaped green that can be succession planted from spring through fall. We’re now referring to it as one of our edible garden “super stars”.

The sign up deadline for our Grow and Graze lunch on March 19 has been extended to March 15th. Please sign up here on eventbrite. We have 10 or so reservations for the lunch available but will need all reservations by March 15.

2019 Raincatcher’s Classes

Grapes growing at The Raincatcher’s Garden


We have three more events scheduled and more coming:

Saturday,February 16th, 10am-noon Grape Pruning and Growing class with Michael Cook, Viticulture Extension Program Specialist for North Texas, Texas A&M AgriLife Extension Service

Michael Cook, Viticulture Program Specialist – North Texas, Texas A&M AgriLife Extension Service, has been consulting with Raincatcher’s to maximize production on our two grape varieties in the vineyard. We planted ‘Carlos’ Muscadine (Vitis rotundifolia) and Champanel, (Vitis champini X Worden), an American hybrid, almost four years ago. All that hard work paid off last summer, when we harvested well over 50 lbs of grapes. Michael will demonstrating proper pruning and training techniques for the backyard grower and provide advice on how to care for grapevines throughout the growing season for a successful crop. The class is free and open to all! Raincatcher’s Garden of Midway Hills is a demonstration garden and project of Texas A&M AgriLife Extension Service and Dallas County Master Gardeners located on the campus of Midway Hills Christian Church. To find the class, please park in the west or north parking lots and come to the shade pavilion in the north garden.

Tuesday, March 26th,  10:30 am Growing vegetables in the home garden, Jeff Raska.

Thursday, April 25th – Plant sale and DCMGA monthly meeting

Details will follow and we hope to add more classes to the list soon.

All of the above classes qualify for CEU credits for Master Garderners.

All members of the public are invited.

When and Why To Plant Trees

“The best time to plant a tree was 20 years ago, and second best time is now.” ​ A Chinese Proverb

We live within an urban forest in Dallas County that comes from the natural topography and citizens who have planted trees around neighborhoods. Our urban forest is very important to our well-being and environmental health. Pavement and buildings cause a “heat island effect” which increases radiant heat within the city. Trees provides shade that helps mitigate this effect by reducing temperatures as well as absorbing pollution and decrease storm water run-off.

According to a University of Washington study, one tree that is 32 feet high can catch up to 327 gallons of water, and smog levels are reduced up to 6%. Oncor provides a tree-planting guide for selecting the right tree for the right location. Even though it is heart-breaking to see so many trees cut down or sculpted, we do understand the need for safety and our own need for reliable electrical service. Click here for the free guide.

Dallas County Master Gardeners have planted a border at Raincatcher’s Garden of Midway Hills, 11001 Midway, that we call the Under-the-Power-Lines garden. We planted tree specimens that fall into the “low” category, staying under 20 feet tall. If you’re considering a low tree for a location near power lines, check out our border to see how the trees might look in your own landscape. Most of ours were planted around 3.5 years ago, including Mexican Plum, Possumhaw Holly, Texas Mountain Laurel, Mexican Buckeye and Royal Purple Smoke Tree (a favorite of ours that isn’t on Oncor’s list). Vitex is another good option, and we have a specimen near our Shade Pavilion. It blooms in summer with big purple spikes and can grow as a large shrub or small tree.


You can find this garden border on the north side of the Midway Hills Christian Church campus along the parking lot. The Dallas County Master Gardeners program is run by Texas A&M AgriLife Extension Service Dallas County Master Gardeners encourage our citizens to plant a tree. Go to the following link which will help you select the right tree for your space, and planting instructions.

Tree Selection and Planting Class

Tuesday, February 5th
10am until noon
Raincatcher’s Garden of Midway Hills, 11001 Midway Rd, Dallas, TX

Community Hall and North Garden

Winter is a good time to establish new trees in your landscape. Tom Wilten will speak on selecting the right tree for the right location here in North Texas and teach how to plant and care for your tree with the confidence that it will provide many years of enjoyment.  Following the class in the Community Hall, you’re invited out to the north garden for an optional tour to see the Raincatcher’s tree demonstrations, including both shade trees and ornamental trees appropriate (and recommended by Oncor) for planting under power lines. The class is free and all are welcome!

Speaker, Tom Wilten, is a Dallas County Master Gardener and practicing general dentist who has maintained a long time interest in plants and horticulture. He loves to watch plants grow, and many of the trees in his large home landscape were propagated from cuttings. He has served as a past president of First Men’s Garden Club of Dallas, Texas, and as a national director and regional president in the parent organization. His original articles on various aspects of horticulture have been published in a national club’s magazine. Always an informative and entertaining speaker, Raincatcher’s is pleased to welcome Tom to the garden.

Raincatcher’s Garden of Midway Hills is a demonstration garden and project of Texas A&M AgriLife Extension Service and Dallas County Master Gardeners located on the campus of Midway Hills Christian Church. To find the class, please park in the west parking lot and come through the courtyard to the south building.  

Seed Starting Indoors

Garden Betty’s blog has been an inspiration to me. The name Betty resonates deeply because of my Mom, Betty Haughton, who was a Master Gardener, class of 2008 and then there’s the fantastic organic practical horticultural information you will want to absorb.

Click here for The No Brainer Guide To Starting Seeds Indoors by Garden Betty and then listen up to what Jim Dempsey, our seed starter says:


Last year’s zinnias and peppers started indoors and then moved to the greenhouse.

 “I use a grow light because I have no sunny location in the house. Our pepper seedlings (slow to come up and slow to grow) are just now coming up. I plan on planting the tomatoes mid- February (in the past I have started too soon)  and our flower seeds shortly after that. Weather permitting, we would like to plant the seedlings (4″ pots) by first part of April.”

Step by Step—How to Build Decomposed Granite Flooring and Paths

The Raincatcher’s Garden has a new look.  We are starting 2019 with durable, *ADA compliant, paths and a floor  beneath our shade structure.  The work has been done by a team of Master Gardeners led by Jon Maxwell who is one of the co-chairpersons of our garden.

Shade structure before!

Jon, we are thrilled with this accomplishment. Hearty thanks to you, Ed Wolfgang, Tig Thompson, Hans Wildburger, Joe LaBay, and Jim Miller (2019 MG Student).

Finished product. Read below for the how-to directions.

Please tell us about the process.

What other options were considered? Why did Master Gardeners choose decomposed granite?

We considered several different alternatives, including installing a concrete pad, putting down a 4” layer of hardwood mulch, gravel and decomposed granite(DG). We ruled out concrete as too expensive and with our Houston clay soils to likely to crack and become uneven. The mulch would too quickly decompose and thus require monthly additions to the pad in order to maintain a comfortable level, and most importantly would not have been ADA compliant. Pea gravel was also considered but again is not ADA compliant nor is it particularly stable for volunteers or visitors to walk on – not to mention the accompanying dust that would coat the tables and benches. Decomposed granite on the other hand, while initially expensive, would provide an ADA compliant surface when a stabilizer is incorporated or applied. The DG floor will over time require some maintenance to maintain an even surface degraded from traffic and/or rain run-off.

You started with bare compacted soil. Would you mine giving us the process from stage 1 to completion step-by-step?

a. Evaluate the soil, its condition, and its grade. We were fortunate that the lay of the land under the shade pavilion was somewhat level and had about a 5 degree slope from the north to the south that allowed for run-off and that it had become hard packed from use and being sheltered from the elements for the past year or so.

You must start with a firm base, the ground may need to be machine compacted or rolled prior to the laying down of the first strata of sub-surface materials. During the compacting process, if necessary, you should add soil to level out the proposed DG site and fix the grade, (slope), of the pad or walkway. If you have a project that is subject to rain water floods, ie downspouts, you should modify the downspouts by either incorporating a rain-harvesting process or by modifying the drainage system.

We have done both, the east side downspouts flow pattern was modified to run underground through a 4” pipe and flow up through a pop-up drain outside of the DG pad, which allows for that rain water to run out into the contiguous parking lot. For the west downspouts we are capturing that rain water into rain barrels, which we plan to use for homeowner demonstrations on rain harvesting and as another water source for our composting station.

b. In order to contain the DG you must use some type of border edging material. You can purchase metal edging from the box stores but it typically is not strong enough to prevent getting waves in it while the DG is being compacted. We selected a 3/16” thick by 5” tall metal edging from Collier Metal Specialties LTD, “COL-MET”, which is located in Garland. Various other edging materials are available in different sizes, thicknesses and colors. The edging needs to be installed about 2” deep into the ground. On the 5” edging that will leave 3” above grade for the sub-surface material and the finishing surface material. The sturdier edging is harder to work with as it requires a saw to cut the sections to fit the desired space. We chose to use 90 degree corners for all of our turns, so this worked out quite well for the pad installation. We used 30 10’ sections, 15 90 degree corners, and 275’ of rubber cap. If you are concerned about weeds, then before laying down the sub-surface material, lay down a fabric weed barrier but this is optional.

c. Add the first layer of sub-surface material. We used crushed concrete purchased from the same source for the decomposed granite, Lowry Sand and Gravel, to establish at least a 1” base. It is far cheaper than any other material that might be used and provides a non-decomposable base. Some projects use only the DG without a sub-surface base but that is considerably more expensive and it does not help to “fix” in position the surface as well. Do not roll or pack the sub-surface material.

d. After the sub-surface base is completed, add the first layer of DG, at least 1.5” is required. Lightly moisten the material and then roll or mechanically compact that layer. The 1.5” layer will compact down to about 1” actual. The initial layer should sit for at least 8 – 12 hours before applying the second and final layer. Once applied, the final layer will again need to be rolled or mechanically compacted as well.

Jim Miller ready to roll!

e. After compacting the final layer of DG you should determine if there are any uneven spots in your pad or walkway. We used a simple method of stretching a string line, both parallel and perpendicular, and eyeing it. If there are uneven spots, level with additional DG, lightly rake to level, lightly moisten and then compact those areas.

f. In order for the pad or walkway to be ADA compliant a stabilizer must be added to the DG. It can be ordered with the stabilizer incorporated, which increases the cost dramatically, or you can purchase stabilizer used as a drench to help make the surface harder. In either case, the addition of stabilizer increases the cost of the project substantially.

g. For safety consideration, since we are open to the public and provide tours to school children as well as adults, we are adding a rubber cap onto the metal edging to reduce the effects of someone falling and hitting the edge of the metal. Also available from COL-MET.

Thanks guys, for putting the metal edging in place and for the rubber caps that will be put on top of it for safety.

How many cubic yards of materials were used and at what cost?

Our project required 8 cubic yards of crushed concrete, about $40/yard delivered, and 20 cubic yards of decomposed granite, about $70/yard delivered. Fortunately, one of our supporters, Arrow Lift Rentals, provided equipment to move and compact the materials.

What was the total cost of the project for this 2200 square foot area?

Total cost of this portion of the shade pavilion project was less than $2,000.00.

Up close and personal with our decomposed granite! Fait accompli!

Now that it is finished so beautifully, what upkeep will be needed?

Fortunately, very little; just an occasional addition of DG in areas of heavy traffic or water run-off. That is one of the benefits of a decomposed granite pad and walkways.

Thank you, Jon.

Arrow Lift employees and machines like this mechanical compactor placed us on solid ground.

More thank you’s to  COL-MET, Abbe Bolich and Arrow Lift Rentals. Arrow Lift helped us get in under the $2,000 line with their labor and equipment at reduced cost. Community partners are so important to the ongoing work of our garden.

*We will be ADA compliant when stabilizer is applied at a later date.

News From the Winter Vegetable Patch at Raincatcher’s

Lovely looking lettuce but guess what Syann told me-it took 3 sowings to get that lovely lettuce because the rain kept washing the seeds away.
