Snowball Viburnum

Posted on March 27, 2024 by Dallas Garden Buzz

March 27, 2024

A view of 3 Snowball Viburnums, looking thru my blackberry bushes. Eleagnus flanking the west side, hellebores underneath.

Spring comes and this is what I see every year out my south-facing windows. What a sight! I planted these 3 snowball viburnums 11 years ago. They have been the showiest, easiest plant choice I have ever made. The buds are chartreuse and and bloom into softball size white blossoms.

As you can see from my picture above, mine are now feet 15 tall and slightly crowded but I don’t mind. The winter honeysuckle that has gotten bigger than I ever expected is pushing one snowball to the East. It is going to be pruned!

Last year even with the unbearably hot temperatures, my viburnums bloomed a second time. There were’t as many blossoms but in that terrible summer heat it was nice to see a few snowballs.

Dallas County Master Gardener Japanese Maple Sale Coming Soon

Posted on January 22, 2021 by Dallas Garden Buzz

The Joy of Japanese Maples

You may have noticed the brilliant reds and golds of Japanese Maples around town in recent months. The foliage colors and textures were more reminiscent of an autumn drive through New England than fall in North Texas!

The Dallas County Master Gardeners are hosting a sale of Japanese Maples in March. Many of us are familiar with the variety “Bloodgood,” however the Maples we are offering are varieties not often available at local nurseries. This is your opportunity to purchase these trees in one- and two-gallon sizes.

There is a place in every garden for a Japanese Maple. They thrive in afternoon shade (the perfect understory tree!) and will make that special spot in your garden a focal point year-round.  

Watch for  the sign-up genius link and additional information including varieties available, pricing, and contactless pick-up details, in February.

Rising Sun Redbud Tree

Posted on October 6, 2020 by Dallas Garden Buzz

During the stay at home order, I found myself watching most of the Texas A&M AgriLife’s Water University online training classes.  The classes were great but one thing I particularly liked was that a lot of the classes are at 6 or 6:30 PM – HAPPY HOUR!!!  I would set up my laptop on the kitchen table, pour myself a glass of something and get out a bag of chips and salsa.  When I knew my friend Sarah Sanders was also watching the class, she would do the same and we would text back and forth about the plants we liked.  It was not the same as attending a meeting together but we are doing the best we can under these unusual circumstances.

We noticed one tree that was mentioned in almost every class.  It was the Rising Sun Redbud tree (Cercis canadensis).  The instructor, Daniel Cunningham (Horticulturist) said he has one planted outside his kitchen window.  Sarah and I were determined to find a spot for one in the courtyard at the Raincatcher’s Garden at Midway Hills Christian Church.  We have a large, square brick planter that was initially planted as an herb garden, which was a great idea since it was so close to the kitchen where we do all our cooking for the garden luncheons.  However, years passed and we now have a huge fabulous edible garden just a few steps away.   It seemed like a great time to repurpose the area for a beautiful view from the church windows.

Rising Sun Redbud Tree, so aptly named. Look at that foliage!

Here is what we love about this tree.  It’s a compact tree (10-12 feet tall with a 10-15 foot spread) and has multiple seasons of interest.  It blooms pink flowers in the spring and attracts birds and butterflies.  Then, the heart shaped leaves start out as yellow, orange and apricot and turn to lime green when it gets hot.  The very best part is that, at some point during the growing season, all of these colors are on the tree at the same time.  Then in the fall, the leaves turn orange.  I’ve also read that the bark is smooth and yellow, making it attractive in the winter months.  It almost seems too good to be true!

 

 

Since September is an ideal time to plant trees, Beverly Allen, Sarah Sanders and I strapped on our masks and headed to the courtyard with shovels and rakes in hand.  Eight bags of compost were added to the bed.  We dug a hole and hoisted a 15 gallon Rising Sun Redbud tree into the planter.

Jackie James, Sarah Sanders and Beverly Allen, the planters.

We are hoping we chose just the right tree to plant in just the right spot so it will be a beautiful and fun addition to the courtyard and also easily visible from the Fellowship Hall window.  Can’t wait until we can get together again to attend a monthly meeting or enjoy one of our delicious luncheons and have the added bonus of getting to look at this tree out the window. Thanks for the idea, Daniel!

As Jackie said, this is a great time to plant trees and here are two videos to help you:

Candlestick Tree

Posted on August 25, 2020 by Dallas Garden Buzz

Candlestick Tree

I should have realized that gardening was going to be an important part of my adult life as I stood in front of a candlestick tree as a child at the State Fair of Texas.  I stood staring at this beautiful, tropical-looking plant with a corn dog in one hand, cotton candy in another and a lizard on a string “leash” pinned to my shirt.  (As far as the lizard is concerned, I feel compelled to quote Maya Angelou:  “Do the best you can until you know better. Then when you know better, do better”!!!).

Years went by and I didn’t give that fabulous plant a thought until I volunteered as a docent for one of the first Master Gardener fall garden tours.  I spent several hours at Kay Passmore’s garden that day and found myself staring at the candlestick tree again.  She had many in her yard and commented that they reseed freely.

For the past couple of years, we have been planting candlestick trees in the courtyard at Raincatcher’s Garden at Midway Hills Christian Church.  At this very moment, there is a big candlestick tree in the courtyard that just starting blooming.  Every time I work in the courtyard, I find myself standing and staring at this awesome plant, but without the corn dog (vegetarian now) and cotton candy (yikes!).  And, thank goodness, the only lizards in the vicinity are the ones running freely in our garden rather than pinned to my shirt (what were we thinking?)!!!

Our lopsided well loved Candlestick Tree in the Raincatcher’s courtyard

The candlestick tree (Cassia alata) is native to Central and South America.  It is an annual in Dallas and grows easily from seed.  It is best to soak the seeds in water overnight and then plant them directly in the ground in full sun after the danger of frost has passed.  It can grow from 6 to 15 feet in a season and it blooms late summer to fall.  It is a drought tolerant plant and it attracts pollinators to the garden.  Another fun fact about this plant is that the leaves fold up at night.

Next time you’re at the garden, take the time to check out this plant.  Or make a special trip to the courtyard just to see it – it will be worth your effort!

If you have never grown this plant, I strongly suggest you try one next spring.  Hopefully, we’ll have some seeds to share by then!

Desert Willow

Posted on August 15, 2020 by Dallas Garden Buzz

When you visit the Pollinator Garden at Raincatcher’s, please take a moment to walk in the garden and see how beautiful and large the desert willow has grown. Tom Wilten would be proud! He gave us this tree just last year, and it’s happily blooming away. I wonder how many trees owe their lives to Tom’s passion for propagating and teaching us how to do it, too? What a wonderful legacy.

Tornado Damage to Trees in Dallas

Posted on December 9, 2019 by Dallas Garden Buzz

Tornadoes ripped through Dallas, October 20, 2019. What a loss for our city when you count property destroyed and trees uprooted or damaged.

 

Many of our beautiful trees were destroyed.

Eric Larner, Dallas County Master Gardener and Citizen Forester and Steve Houser, also a Dallas County Master Gardener and President    of Arborilogical Services discuss what happened and what to expect in the paragraphs below. They also remind us-we have a lot of tree planting ahead!

Eric, do you have anything you would like to tell the readers of our blog about trees after the tornado?

Have there been any estimates of the loss in terms of trees? I wonder what percentage of our tree canopy in Dallas was destroyed?
 
 
What recommendations would you give?
 
 
Maybe we should have a class so people could come ask questions and see our tree selection.
 
Ann Lamb

From Eric Larner-Great questions – Of course, the damage a tornado (100+mph winds) against ANY tree is almost always 100% fatal to the survival of the tree no matter the size of the tree. But tornados take weird and strange paths(i.e. total destruction on one side of the street and very little damage on the other side).

I would refer you to Steve Houser on estimates of destruction to the city’s overall tree canopy. I do know that to replace the benefits of one very LARGE tree( 40-50” caliper) takes 150+ 3” trees planted and that would take around 25+ years to achieve. So you see, we will need to plant a lot of trees in our city.

A neighborhood class talking about medium – large shade trees  would probably focus on alternative choices to red oaks and live oaks in the metroplex.

Eric Larner

From Steve Houser-As Eric noted, the damage often follow unusual paths.  We had a storm in late June with 70 MPH winds that damaged properties in south Richardson all the way to downtown Dallas.  One of the ten recent tornados contained over 140 MPH winds that took out houses and most (or all) of the trees on a property.  Many huge Oaks were blown over and those that survived often had extensive damage.

Eric’s notes  are accurate calculations regarding how long it takes to replace the biomass (or foliage) of one large tree.  Although it replaces the biomass in 25 years, it does not replace a cool and old tree for around 100 years.

If you consider the losses from both the events noted above, a guess at the loss in canopy cover would be between 4 to 5%.  Although it does not sound extensive, it was easily over 100,000 trees lost or damaged.

Trees lost or damaged included up to 90% of the canopy coverage in specific areas with 140 MPH winds and less in areas with 60-100 MPH winds.

We have handouts on recommended species.  As Eric noted, Raincatcher’s Garden is a great demonstration garden for some of the choices.

  • It is always best to check with a consulting arborist and ask for a full assessment of all trees.  Keep in mind that it may take some time to get them out but they can help to detect trees that can fail structurally in the future and determine the best course of action for a damaged tree.
  • DCMG`s have already been taught about cabling/bracing, reducing end weight on long limbs and determining weak forks in trees, to help reduce future damage or losses.
  • If a tree lost 20-30% of its foliage, it may be salvageable and recover.
  • If a tree lost 40-60% of its foliage, it will never look the same again but may have a chance to survive.
  • If a tree lost 70-100% of its foliage, most arborists recommend removal and replacement.  However, if the primary branching structure is not severely damaged, they will not look good but some of them can be saved.  Some folks may leave the tree for a year or two to see if it grows back and how it looks.  In some cases, another tree or two will be planted nearby and to possibly replace the damaged tree at later date.

Steve Houser

The Raincatcher’s Garden will host a tree class in early 2020.

As Eric said, it will be about tree selection, and also care of trees.

We will announce the date of the class in January, 2020.

Dallas County Master Gardeners and Japanese Maples

Posted on October 1, 2019 by Dallas Garden Buzz

Everyone loves Japanese Maples! Dallas County Master Gardeners were able to learn about them from expert, Scott Hubble, at our September meeting last week.

Scott works at Metro Maples in Fort Worth  and shared a wealth of information about these trees which come in all shapes, sizes and many colors.

Our Texas sun is the most important factor to consider when picking a location for a Japanese Maple. Morning sun with shade in the afternoon is generally perfect.

Japanese Maples are well situated when they are under the canopy of larger trees receiving dappled light throughout the day.

Remember they do not like soggy roots so plant them in areas with drainage.

No more words, let’s gaze at these beauties.

Look carefully inside this Japanese Maple to see homeowner’s mailbox. This  25-30 year old tree grew around the mailbox.

Thank you Metro Maples for the presentation and pictures.

Ann Lamb

All Master Gardener meetings are  held the 4th Thursday of the month at varying locations are open to the public.

Tool Time and education for all Thursday, October 3rd at 10am at The Raincatcher’s Garden. Click here for details.

Don’t forget to visit the Red Maple Rill at the Dallas Arboretum with over 80 varieties of signature Red Maples.

When and Why To Plant Trees

Posted on February 4, 2019 by Dallas Garden Buzz

“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. http://texastreeplanting.tamu.edu/

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.

Trimming Vitex

Posted on October 17, 2017 by Dallas Garden Buzz

Hopefully, you have taken a moment to watch Evelyn  explain what our Vitex tree needed. Click here for the video if you missed it.

Vitex tree in need of a trim.
Here’s the before picture.

The dormant season is the recommended time for pruning, but sometimes your work force, needs, and timing come together in other seasons.  Evelyn  and Susan, experienced gardeners, took our large, unruly bush and gave it a comely shape.

Here’s the result:

The Strange, True and Unappreciated Story of Oak Galls

Posted on July 25, 2017 by Dallas Garden Buzz

Insects are as a group complicated and mysterious. Everyone loves dragonflies.  Butterflies have clubs and societies devoted to their protection.  Gardens are designed just to attract them.  There are t-shirts and even jewelry to honor them.  Why every sighting seems to cause joy and excitement.

Oak Galls are amazing and mysterious—but for some reason nothing seems to be done in their honor.

Handfull of Oak Galls

This is not fair–and this is why. Oak galls are made by tiny creatures almost all of these are cynipid wasps.  Just as there are different types of butterfly that will lay eggs on only a specific type of plant, different types of cynipid wasp that will only lay eggs on one type of oak.  The tiny egg produces chemicals that cause the tree to produce the strange growths called galls.  The galls are different for each type of tree.  The larvae hatch inside the gall where they eat and live until they are mature and able to hatch, fly mate and start the process all over again.

<Larvae Centered Inside Oak Gall, Cradled by Pink Fingernails

The galls are hard to see until they fall to the ground. If this happens before the creature is mature the gall can be cut open to reveal the little larvae.  Of course, then it will not become a wasp—but this might be ok—in the interest of science.

The larvae only eat inside the gall. They do not damage any more of the tree.  In fact the tree is almost never harmed by galls.  The adults are wasps, but they do not sting.  The galls themselves can be beautiful like the oak plum galls which do indeed look like little fruits.

Gall formation is unpredictable. Some years there are a lot of them, other years very few.

All in all these are simply little creatures that happen to have developed an amazing way of protecting themselves as they grow to be adults.

Have you ever heard of anyone planting oak trees in hopes of attracting cynipid wasps—it is doubtful. There seem to be no societies to appreciate and protect them.

This needs to change. Look around for oak galls.  Tell your children their wonderful and amazing life story.  Now surely someone could design a great t-shirt!!
