The church garden —
journey of a thousand miles|
It seemed like an impossible task for an overly ambitious men's senior Bible study group to accomplish. They decided to do something about the unappealing nine acre church grounds at Bannockburn Baptist in Austin.
The group's program started in 2000 with a prayer and a pledged monthly financial commitment from the senior men's class. Work commitments were scheduled within the group and I volunteered, as a retired farmer who knew something about plants, to help turn the ambition into reality. I, like so many retirees, was looking for something significant to pursue in my retirement. The garden challenge seemed to be made to order, although a bit of a stretch for someone 75 years old. But I had been a garden enthusiast all my life and had actively pursued gardening as a hobby for more than 50 years.
I knew that you did not direct a major landscape project of this magnitude without a great deal of knowledge and the Lord's blessing and direction. This is especially true in Texas, where harsh growing conditions are the norm and gardening can be very unrewarding at times.
As chairman of the group, I began an extensive study program during the next two years to gain the practical knowledge necessary to carry out the plan. I took advantage of training offered by the Lady Bird Johnson Wildflower Center, Zilker Botanical Gardens and other garden organizations. I also completed the Capitol Area Master Naturalist and Travis County Master Gardner programs in my quest to understand the complexities of central Texas gardening. I accumulated a considerable botanical library and spent hours each week learning how the how, when, and where of plants adapted to my area that would benefit wildlife, provide color and aesthetic appeal, and survive on acceptable maintenance regimes. Finally, after two years of preparations, the church grounds transformation began to take shape.
Members of my Bible study class, some in their 80s, were ready to go. Several discovered the rewards of gardening and experienced first hand that it is a lot easier for seniors to get down on one knee to pull weeds than to get up afterward. Nevertheless, teamwork and determination prevailed. The dedication of these seniors began to inspire younger volunteers and the work crew began to grow.
The gardens, after a slow start, began to develop momentum and suddenly the beauty, peace and serenity of a garden began to register with the members as a special and lovely addition to their church home. Soon other groups began to come on board. The Boy Scouts built a water garden. Community service and youth groups helped build rain water collection gardens. Master Gardeners and Master Naturalist trainees did garden specialty work.
As the gardens developed, support continued to build within the community. I was astounded two years ago when an older lady pulled up on the roadside where I was working and handed me a check made out to the church for a thousand dollars to help support the gardens. As I was attempting a sputtering thank you, she explained that she drove by every day and looked forward to seeing the seasonal changes in the roadside gardens. To the astonishment of many, the support has continued from this real life angel who lives somewhere down the road. Other folks joined her. Plants and materials poured in from many individuals and groups, sometimes overwhelming the volunteers. Organizations like the Master Gardeners Association and the Garden Club of Austin were more than willing to help in the creation of another public access garden for Austin.
The gardens have become very special to Bannockburn's members, who have the opportunity to invite friends to visit the "garden church" in southwest Austin. The grounds are becoming a local attraction, hosting garden tours featuring winding waterways, rose gardens, and more than 20 specialty gardens. Streams of commuters enjoy the roadside gardens, especially when the roses, larkspur, and bougainvilleas are in bloom.
Children at the Bannockburn School just have to step out of the classroom door to enjoy nature study. Winkey, the resident barred owl, stares the children down from its nest box in a tall red oak tree. Hummingbirds and butterflies abound, enjoying special plantings on their behalf. Frogs and fish thrive in the water gardens and pond. Rabbits, opossums and turtles make regular appearances to the delight of the children. Teachers are challenged to keep the children moving from one building to another due to the many garden distractions along the way. The children are especially enthusiastic about the vegetable gardens, and the race is on to see which class has the most tomatoes on their plants. A sixth grade class with 30 tomatoes won this year.
The gardens provide an oasis of habitat in an urban setting. Certified by Texas Parks and Wildlife as an official Texas Wildscape, they provide food, cover, and water for native birds, butterflies and other wildlife. Plant trial work for diverse groups such as Texas A&M University and the American Iris Society require careful observation and meticulous record keeping by the volunteers to ensure integrity of the plant trials. The senior group has begun a hands-on help program to assist other churches, schools, senior citizen centers, and extended care facilities. Three Master Gardeners are on call to assist others in starting similar garden programs.
The latest challenge will be working with other church members to develop a master landscape plan for the entire campus.
The Bannockburn gardens became a reality because a group of seniors saw a need and decided to act. If opportunity for service begins at retirement, than as the Chinese saying goes, "A journey of a thousand miles begins with but a single step."

'PET' project could
reduce East Texas cities' water woes|
By Robert Burns
The National Oceanic and Atmospheric Administration's long range forecast is for below-average precipitation for East Texas in coming months.
But even if the prediction proves false, being water conscious when irrigating lawns still makes sense, both economically and environmentally, said a research associate with the Texas Agricultural Experiment Station.
"And it's almost a no-brainer, now that we have the right tools," said Indre Pemberton, who is based at the Texas A&M University Agricultural Research and Extension Center at Overton.
Pemberton maintains the center's automated weather station and the associated Web site at http://etweather.tamu.edu/. Part of the Web site is dedicated to help irrigators calculate potential evapotranspiration.
The term is a mouthful, and usually abbreviated as "PET," she said. The concept is straight-forward, though.
"PET is an estimation of the combined loss of water through a plant's vascular system combined with evaporation of water from the soil surface," Pemberton said.
Both factors are influenced by temperature, humidity, sunlight and wind, all of which are measured every 15 seconds, 24 hours a day, by the center's weather station. The data are averaged to calculate the potential evapotranspiration.
Though the formulas behind the PET indexes are complex, using the information to determine how much water to put on home landscapes takes only two simple steps, Pemberton said.
First, take an audit of your irrigation system. Set out some flat-bottom containers around the yard and irrigate for 10 minutes. The more cans, the better, but a half dozen will do. Use a ruler to measure the amount of water in the containers.
"Write the numbers down on a piece of paper, add them up and divide the sum by the number of cans you had — to get an average number," Pemberton said. "This lets you know how much water was delivered in 10 minutes. Multiply by six, and this gives you the amount of water delivered in one hour."
After determining the amount of water supplied by your irrigation system in an hour, go to Pemberton's Web site and click on "PET." The evapotranspiration data are calculated and posted daily. To figure how much water to apply, simply add up the numbers, using either the Overton or the TxEt column for all the days of the month since the last irrigation was applied.
For example, if you're watering on April 7, and the last time you watered was on April 1, add up the numbers April 1 through April 6. The total is the amount of water you need to apply.
"That's for people who irrigate once a week. Some people irrigate every other day, so they would add up the PET numbers for the two previous days," Pemberton said.
To simplify things further, Pemberton has supplied an online calculator at the Web site.
Why two different calculation columns?
"It's just two different ways of calculating PET," Pemberton said. "We provide both for comparison. Either one should be fine for home landscapes."
Pemberton noted that for homeowners, the difference in the two calculations are fractions of an inch — small enough not to worry about.
"Also, if it rains, subtract the amount of the rainfall from your PET value," she said. "Because the rain has replaced that amount of water for you."
On the average, most householders over-water 30 percent to 50 percent, said Dr. Jim McAfee, Texas Cooperative Extension turfgrass specialist. Not only does over-watering waste resources, it also promotes many turfgrass diseases, he said.
"I was talking to a professional lawn care business owner in Tyler, and he said they're already seeing brown patch," said McAfee, who is based in Dallas.
McAfee noted that brown patch is associated with cooler temperatures as well as over-watering.
For more information on brown patch in home lawns, see http://aggieturf.tamu.edu/answers4you/disease/brownpatch.html.
McAfee said there a number of ways being considered by the Texas legislature to deal with the problem. One way might be to mandate the installation of automated home irrigation controls that use sensors to record local temperature and humidity. Microprocessors in the devices calculate potential evapotranspiration for the home lawn, then disperse water accordingly.
"They're amazingly accurate, giving results that are with 90 percent of those by the (professional) PET stations," he said.
Until those units are commercially available, homeowners' best bet is to take advantage of PET data like that supplied by Pemberton, he said.
"Take cuttings to make grass plugs for lawn repair before mowing St. Augustine lawns," writes Beverly Nord. "Cut the 'runner' just below the node and stick the cutting into potting soil. When rooted, plant in those bare spots and water well."

Many people think that moon gardening works because all water is affected by the movement of the moon and plants are mostly water. Both the sun and moon affect water through their magnetic pull but the moon is much closer to the earth hence its influence is stronger.
