  Hundreds of flowering bedding plants to be showcased at upcoming Horticultural Field Day

By Robert Burns

On June 28, nursery growers, greenhouse managers and gardening enthusiasts can view field tests of flowering bedding plant varieties at the annual Overton Horticultural Field Day.

"We have over 800 varieties this year and that includes 180 varieties in the container trials," said Dr. Brent Pemberton, horticulturist with the Texas Agricultural Experiment Station.

The field day will begin at 8:30 a.m. at the Texas A&M University System's Agricultural and Research Center's North Farm site. The tour will continue at the North Farm site until about 10:30 a.m., then move to the Overton Center's headquarters building where a demonstration garden is located. Lunch will be served at about 11:30 a.m.

Pemberton began trials of bedding plants at the Overton center to serve the commercial greenhouse and bedding plant industry. In recent years, the industry has had a $500 million annual economic impact on the region, according to the Texas Agricultural Statistics Service.

Before Pemberton began his trials, there were few if any tests under East Texas conditions of the many new varieties released by seed companies each year, he said.

Since the first field day with less than 100 varieties, the event has grown to include vinca, ornamental peppers, trailing petunias, verbenas, begonias, portulaca, zinnias, geraniums and ageratum. This year, there will be an emphasis on impatiens, including regular impatiens, New Guinea varieties and some miniature types, Pemberton said.

"There's also a good selection this year of angelonia and cuphea," he said.

The field performance trials are now replicated at the Texas A&M University Dallas Center.

"We also coordinate trial results with the Dallas Arboretum," Pemberton said. "Over 5 million consumers in the northeast Texas region now have the opportunity to see how promising new plants from all over the world perform in our climate."

Preparation for the trial has also become a way for local Master Gardeners to fulfill their requirement for community service. Moreover, with the ever-increasing number of entries by seed companies, the trials could not have grown to be so all inclusive without the volunteers, Pemberton said.

"The Smith County Master Gardeners Association is an integral part of these trials," he said. "They provide hundreds of hours of labor every year. They are how we get these things planted and how we get this done."

Registration is free and will include a lunch. The Overton center is located 1 mile north of downtown Overton on State Highway 3053.

The North Farm site is about 4 miles north of the center on State Highway 3053. For an online map, go to http://overton.tamu.edu/flowers/fieldday.htm.


  Strawberry jars forever

By Michael Bettler
Lucia’s Garden

If you are a casual gardener I do not recommend those "pots with pockets," also known as "strawberry jars," unless you have time and patience to carefully make the initial planting. Once planted, they are low maintenance.

A. Purchase a TERRA COTTA (flower pot material) strawberry jar.

B. Choose your plants carefully: mints, thyme, oregano, prostrate rosemary, or any small perennial flowering plant varieties. Line them up in the order in which you want them to be planted in the strawberry jar, bottom to top. The choices are yours to make. If you want to plant annuals (Globe Basil, stivia, chives), you can plant two to four on the top, to finish the jar. Planting them on the top assures the plants in the pockets that they will remain undisturbed.

C. Prepare your soil mix as 1/3 playground sand; 1/3 potting soil (without the water-saving crystals); 1/3 fine compost. Mix thoroughly.

D. Make some ice tea or have a lot of your beverage of choice ready as planting will take some time!

E. To properly plant a "strawberry jar":

(1) Cut a piece of 1" to 2" wide PVC pipe the interior height of the strawberry jar; drill 1/4" holes in it every 2" to 3" along its length. Cap one end of it. This will be the "bottom end."

 (2) Soak the pot in water for at least 15 minutes. Totally soak the pot...deep bucket...kitchen sink...bath tub. This is to assure that the pot does not absorb water from the soil on the initial planting and dry out the root system. (CAUTION: be certain you are planting the strawberry jar outside, near the garden, because it can get very messy, especially the first couple of times. It is also a good idea to place the strawberry jar where you want it to remain [deck, patio, porch, walkway] as it will get heavy, depending on the size.)

(3) Place a layer of gravel on the bottom of the pot with a pot-shard over the drain hole to assure that the pot drains and breathes properly.

(4) Stuff a few pieces of paper toweling in the "top end" of the PVC pipe to form a temporary plug.

(5) Stand the capped PVC pipe on top of the pot shard ("bottom end" down) and begin to place soil into the pot. (The paper towel is to keep soil from entering the PVC pipe.)

(6) Fill the strawberry jar with soil until you reach the level of the first (lowest) pocket.

(7) Un-pot the plant you want to go into that pocket and place it into the hole by reaching into the mouth of the jar and placing the leaves OUTSIDE the pocket, leaving the root ball inside the jar, roots facing the PVC pipe. COVER THE ROOT BALL with soil, but DO NOT PACK THE SOIL DOWN. (Is it getting crowded in the pot?)

(8) Unplug the PVC pipe briefly to add some water and start the "internal irrigation" system. (DO NOT WATER HEAVILY as you will be watering again and again with each successive pocket.)

(9) Let the soil around the roots settle, replug the PVC pipe and prepare for the next pocket.

(10) Plant that second pocket and fill that side of the jar to cover the roots, unplug the PVC pipe, water it and replug the PVC pipe. Then work on the next pocket, then the next pocket and the next pocket working your way to the top with plant - soil - unplug - water - replug - plant - soil - unplug -water - replug - plant - soil - unplug - water - replug (etc.) until you have filled the top-most pocket.

(11) Bring your soil line up to about 1" below the top of the strawberry jar/PVC pipe level, withdraw the paper towel plug at the top and give it one more watering.

(12) Now replug the top of the PVC pipe and plant the top level of the pot, careful not to get any soil in the PVC pipe.

(13) Sprinkle the top planting and add a layer of course sand (contractor sand) or pebble gravel to just below the level of the PVC pipe.

(14) Unplug the PVC pipe and give it another light filling of water and then just let it sit. Take a picture so you can show it to your friends while the plants are small; they'll grow into their environment.

You are done. Sit back and enjoy the results of your labor. And in a few days, the appreciative plants will respond to your care and you'll have a pot that you can be proud of for a long time to come.

NO HEAVY WATERING! (You could "wash-out the pockets.") When it looks a bit dry (remember the roots are in the middle of the pot), give the pot a "drink" (or two) down the PCV pipe, with a good "sprinkle" to the plants on the top.

You can also "cap" the top of the PVC pipe to keeps snails, slugs, dead leaves and dirt from falling into it, but try not to have it stick up too high above the gravel line. And remember that the plants on top will fill in their space, so the ugly pipe won't show too long.


  Foxtail barley
Hordeum jubatum l. (Grass Family)

By Robert Dailey
Freelance Writer

Foxtail barley is possibly one of the most beautiful "weeds" in existence, if not the most beautiful, particularly in its younger stages.

Susceptible to any breeze, its soft green or purplish plumage sways gently. Stronger breezes ripple the tops, while bending the stalks. It is truly a dramatic perennial as well.

Although classified as a weed — see Weeds of the West (Western Society of Weed Science) — the flowering and mature plant is simply majestic.

Plant it in your garden, as an accent piece, and you’ll never regret it. There may be volunteers, and you may want to replant these in specific areas.

Foxtail barley thrives in low-to-mid-elevation areas but it also has populated subalpine areas (such as the Colorado Plateau). It likes poor soil, particularly saline and alkaline soils, and can often be found in poorly drained areas, such as the edges of animal ponds, ditches, and draw-down reservoirs.

The plant flowers from June to August, depending on when the seeds germinate. During that period, until the seedhead forms, the plant is great food for cattle, mule deer and elk, and even moderately for sheep.

However, when the seedhead forms, the sharp, jointed spikes of the seeds can stick in the noses and mouths of browsing animals. The seedheads also get into the wool of sheep and can dramatically reduce the value of the wool.

Most browsing animals will avoid the plant after the seedhead forms.

Growing Foxtail Barley

The plant reproduces readily by seed, although some nurseries do offer mature plants.

They like poorly-drained soil, high in alkaline and/or saline content, so should do very well in the caliche (adobe) soil, and alkaline soils of western and southern Texas.

"I enjoyed the bit on Water from Stone ("A Hill Country nature-western")," writes Beverly Nord. "If you haven't visited Selah, I suggest that you do. It is amazing what Mr. Bamberger has done and is continuing to do there. Fortunately Bamberger likes to tell the story, and never tires of questions."


  Gardening tips

"Planning a vacation this summer but can’t find a neighbor to water your valuable plants?" asks Jimmy Johnson. "Just add extra mulch to your vegetables and flowers and water well before you leave. Move container plants temporarily into the shade and set them in pans of shallow water."

  Did you know...

One bat can find and devour more than 500 mosquitoes an hour. So if you are looking for an organic mosquito control product or technique, the best one we can think of is to install a bat house to encourage bats to work your landscape at night while you sleep.
