five ornamental trees, several hundred azaleas, a creek bed, walking trails, formal settings for entertaining, and secret gardens for solace.

Southern Botanical, inc.corporate campus courtyard

This large, Dallas-based company’s private courtyard, designed by Talley and Associates, is the result of a total renovation to create an inviting outdoor space for company employees.

The narrow courtyard is surrounded by windows on three sides, allowing machinery access on only one 25’ side. Two 12” caliper multi-trunk cedar elms were installed by heavy machinery after pouring concrete, yet before installing hardscape. Two fountains were built with black granite veneers and water weirs to properly meter water movement and sound. All plumbing had to be buried or routed to the exterior of the courtyard to muffle noise.

The landscape team served as plant consultants. Three uniquely designed irrigation areas provide zones in shade, full sun and overhang areas. Existing utility lines for the building exit 2’ to 16’ below ground, requiring special care during digging.

lamBert landScaPe comPanyregency Garden

Working within the confines of an estate that was originally platted nearly one hundred years ago, our firm was asked to design and build a garden in keeping with this stately

Regency-style residence. Our clients desired a series of garden rooms that responded to the site’s landscape features, spoke to the architecture of the home, and incorporated their design sensitivity, while providing adequate entertaining space for either impromptu family gatherings or charitable balls.

Early in the design process, we introduced the topic of sustainable design. Included within our master plan are an underground water-harvesting cistern, existing material transplants, and the relocation of seven mature trees.Challenges encountered include working with the Corps of Engineers in a floodplain, transplanting seven 18-26” caliper trees, and scheduling to work concurrently with the home’s general contractor and subcontractors. The finished project is a stunning setting true to the architectural style of this one-of-a-kind residence.

The homeowners envisioned the transformation of this rugged hillside into a relaxing, interactive, visually appealing, private retreat. Our firm was asked to create

a series of meandering streams with numerous waterfalls and multiple vantage points, such as the cantilevered deck, gazebo, and multiple sitting areas from which to enjoy the view. The project presented challenges that included slopes exceeding 45 degrees, large trees that restricted equipment use, and preserving existing trees. The final project ended with an 80-foot stream with more than 35 feet in elevation change, 300 square-foot deck, 144 square foot gazebo, and over 150 tons of stone.

cuStom GardenS, llcPrairie dog river ranch

This site, located on top of a canyon, and not occupied full time, posed some unique maintenance challenges. Temperatures exceed one hundred degrees in the

summer and drop below zero in the winter, with winds exceeding sixty miles per hour during both seasons. The wildlife is very diverse and the owners have feeders and water holes within two hundred yards to encourage the wildlife for viewing. They entertain guests and want the landscape to look good because they spend so much time outside looking at the canyon and its inhabitants.

KrauSe landScaPeriata Park

This once vacant office building needed a total hardscape and landscape makeover. One of the major challenges was to make the site safe and accessible for pedestrians as the

office was open during the construction phase. This renovation combined good design and functionality, resulting in a workplace that fulfills the client’s desire for an attractive, welcoming respite for employees and visitors. The project features a pergola, dual-function raised planters that host plants and serve as seat walls, a reconfigured 75’ long stairway, and ornamental trees and an abundance of seasonal color planting to keep the courtyards in constant color.

The property is lined with Boxwood, Holly and Ligustrum hedges requiring weekly pruning. Fig Ivy a-lines the walls of the house and needs to be trimmed

at least one to two times per month. When seasonal color is planted, the client requires no dirt to be showing. They want to see pot to pot planting for immediate results from the site’s many color beds. The irrigation system requires weekly monitoring, with the Zoysia turf being fertilized and treated for weeds 5–9 times per year. Two fountains on the property require a supervisor to check them at least twice weekly.

Silver AwardmcduGald- Steeleaustin hillside Garden

The client desired a design solution that possessed a lush, festive, somewhat tropical feel. The site was on a hillside falling 30+ feet from front to back, which required major

grading and drainage solutions. A large concrete retaining wall was formed to support the entire pool garden. The garden’s paving and planting was formed above existing grade using concrete bags as forms. The elevated nature of the pool garden created complications for access and material placement. Poor soil/ subgrade conditions in the Austin area do not provide ideal growing conditions for tropical plants; rock excavation and soil amendments were necessary.

Silver AwardmcduGald-Steelea city View/lake Side Garden

The client asked us to design and build a front garden that would expand their entertaining space. We created cut limestone terraces, seating areas, a detailed fountain,

and a redesigned spa, and enhanced the pool with mosaic tile to present a monolithic deep ocean blue aesthetic. Additional care was taken to protect and nurture the existing trees. The intricacy of the fountains limestone and tile mosaic demanded precision craftsmanship. These improvements added to the garden’s lake view perspective and greatly enhanced the environment for visitors and owner alike.

In 2012, the Hipolito Garcia Federal Courthouse underwent a LEED accredited renovation that included creating an expansive second floor green roof. Our firm assisted the

design team and general contractor with plant selection, installation technique and logistics. Challenges were getting 6,80 modular trays weighing 80 pounds each to the project site and making informed horticultural plans, as a two-story section of the building is surrounded by six-floor wings on all four sides, creating a recessed, viewable rooftop with shade areas created by the building’s own shadow. This project was accomplished by careful planning, expert installation crews, and excellent project management.

Entries

quALity And vAriety The quality and variety of your photos are central to the evaluation process. Scrutinize the composition of each photo and make sure it tells the story of your project. Your photo descriptions are read aloud to the judges as they examine the photos, so use descriptions to direct attention to the extraordinary features of your project. Take pictures specifically for the judges, don’t just use photos you already happened to have. Make sure the photos show what you want to describe; take a picture to define your description, not the other way around.

professionAL photographerHire a professional photographer or use a high quality camera that gives high resolution images. If you only

capture 20 photos to submit 15, there isn’t much room to weed out the weakest ones. If you capture 300 images, there are more options. We suggest taking about 20 shots for each photo you plan to enter.

overaLL shotProviding an overall shot gives the judges a sense of context; the subsequent detailed shots will make more sense if judges have a sense of the space. For installation entries, “before” shots are just as important as “after” shots. Take photos at each phase in the process— before, during, and after. Take photos from the same angles, particularly for wide shots, to show a sense of the transformation that has occurred. For a design entry, take photos when flowers are in bloom, and/or in different seasons to show variety in color. For a maintenance

entry, take photographs 2-3 days after mowing, when it still looks pristine but not as “scorched” as immediately afterward.

time of dAyTime of day matters; photos look different at different times. They also look different if you take them on sunny versus cloudy days. Typically, the best times are early morning or just before sunset on overcast days, but use your judgment and pick the time that makes your project look the best.

projeCt storyRemember that you are telling the story of your project through 15 photographs and photo descriptions. Each image is an opportunity to show how your project meets the judging criteria, and each image description is a chance to explain to the judges what you’ve accomplished.

The Texas Excellence in Landscaping Awards judging panel is composed of Texas judges who are experts in regional conditions and landscaping feats meriting distinction, thus elevating the criteria for winning submissions to a standard higher than many other awards programs. Judging is done in the blind and entries are judged on their own merits. Texas Nursery & Landscape Association has compiled tips and comments from judges over the years to provide easy, do-able actions for this elite awards program.

The Economy

Green Industryand Texas’

The horticulture industry, often referred to as the “Green Industry,” is a significant force in the Texas Economy. It includes growers, greenhouse nurseries, sod producers, herb producers, cut-flowers, retail

garden centers, florists, and landscape and tree services.

This report was made possible by a grant from the Texas Nursery & Landscape Association. The Data was obtained from the Texas Comptrollers of Public Accounts (TCPA), Baseline data from the Green Industry Research Consortium National Nursery Survey. Others who contributed with this report include Carmen Guajardo (TCPA), Dan Hanselka, Dean McCorkle, (Texas A&M AgriLife Extension Service) and Alan Hodges (University of Florida). This report complies with the terms of the TNLA contract. The authors welcome comments or information about the usefulness and implications of these findings.

The complete study evaluates Green Industry sales in Texas by sector, and then estimates economic contributions to the Texas Economy in terms of output, employment and value added. It, and an hour-long webinar recording, are available in their entirety at www.tnlaonline.org

T n l a g r e e n

Green Industry Sales in Texas Total industry sales for the Green Industry were $15.6 billion dollars in 2011, the most recent year for which data are available. The baseline sales figures for the nursery and greenhouse sector were updated to the latest National Nursery Survey data from the Green Industry Research Consortium. This year’s report shows an increase in sales for all sectors of the Texas green industry, including production and manufacturing, horticultural services and retail.

Production and manufacturing was up to a record high of $1.9 billion in sales. Most of the increase in this sector was due to a large increase in the lawn and garden equipment manufacturing as we continue to see a shift from hiring landscaping services to more do-it-yourself gardening. This also explains the small increase in the landscaping sector, with that trend starting to reverse as we pointed out in last year’s report. Retail is also up as consumers’ confidence and general expenditures were also up in 2011.

Total industry sales, including grower, landscaping and retailing sales increased 8.74% in 2011 for a total of $15.6 billion in gross sales. The grower sector experienced the highest increased in growth with almost 20% for a total of $1.9 billion, the highest sales level recorded for the grower sector. The landscaping sector had a slight increase of only about 3% in 2011 for total sales over $3.5 billion. With this slight increase sales of the landscaping sector are still below the highest levels of 2007 and 2008, with

Texas Superstar® Promotions for 2013

blackberry ‘natchez’february 2013 Promotion

Blackberries have been grown in Texas gardens for years and in fact many have grown up picking dewberries, i.e. blackberries on the side of the road. Thanks to the University of Arkansas breeding program there are now several thornless varieties which are productive with quality fruit. The ‘Natchez’ blackberry is suited to a wide array of Texas growing conditions. It is a semi-erect plant, so a trellis will be needed. Production potential is quite good as the berry is very large, averaging eight to nine grams. The fruit of ‘Natchez’ are elongated, somewhat blocky and very attractive with an exceptional glossy, black finish. It thrives in USDA plant hardiness zones 5-10 and has good disease resistance. No substantial common diseases have been observed including orange rust, fruit anthracnose and double blossom/rosette. It ripens early in late May to early June. It will no doubt be a winner in many Texas gardens!

Tomato bHn-968april 2013 Promotion

BHN-968 is a naturally determinant plant with excellent production and awesome fruit quality. Since the plant is short-statured in growth, good fertility is required to produce optimum yields. The key nutrient will be nitrogen. If adequate fertility is not maintained, the tomato bush

will be small and produce much less fruit. BHN-968 tomato is the most naturally disease-resistant cherry tomato we have seen in our evaluation trials. It is genetically resistant to Verticilum Wilt and Fusarium Wilt (VF) as well as Tobacco Mosaic Virus (T) and Tomato Spotted Wilt Virus (TSWV). It is the first cherry tomato variety to be nematode resistant (N) since Texas A&M developed ‘Small Fry.’ The 968 tomato fruit is ½ to ¾ inch in diameter with the sweetest (four times sweeter than a comparable cherry tomato) taste of any cherry tomato ever tested by Texas A&M AgriLife Extension Service. This is the first tomato of any type to receive unanimous favorable rating at every testing. It will be a favorite cherry tomato of home gardeners and patio (container) growers.

napier Grass ‘Princess Caroline’May 2013 Promotion

‘Princess Caroline’s’ beautiful wide leaves are a deep purple color which reflex gracefully on a vase shaped plant. It does not flower, but grows 4 to 6 feet tall depending on watering and length of the growing season. It is a recently developed Napier grass variety which is a trispecific Pennisetum hybrid from a breeding program at the University of Georgia. Unlike its predecessors ‘Prince’ and ‘Princess’ (bispecific hybrids), it is

The Texas Superstar® Executive Board is excited to announce 2013’s promotions. Promotions include a news release to over 2000 media outlets and contacts. Texas Superstar® plants are usually identified with a plant tag in retail outlets. Tag sales provide revenue to support trials

and development of future promotions. Texas Superstar® tags are currently available at no charge from TDA for use in tagging plants for retail sale. Contact TDA for information regarding tags and other promotional materials.

resistant to leaf spot disease seen in the eastern part of the state on older varieties. It is very heat and drought tolerant and is perennial in most of the state. It will freeze to the ground, but makes rapid growth in spring to make a strong statement in the landscape. In north Texas, it can be overwintered if temperatures are mild and it is grown in a protected location. Very little fertilizer is needed. Nitrogen fertilizer will cause leaves to green up and lose the striking purple foliage that is a hallmark of this new Texas Superstar®.

Mari-mums august 2013 Promotion

With the heat and the drought of the past two summers, the value of a tough attractive plant is evident. Enter the mari-mum for late summer and fall color. Mari-mum is the concept of using large-flowered hybrid marigolds in place of chrysanthemums in the landscape. They have blooms

with similar floral appearance to chrysanthemums providing a punch of color just when the fading garden needs it. The flowers last 2-3 times longer than chrysanthemums, are inexpensive and don’t require the constant pinching and pruning. By planting mari-mums in late August to early September, cooler autumn temperatures greatly reduce spider mite pressure. Transplant these fall annuals in containers or in landscape beds and they will provide outstanding color until late in the season. Mari-mums need a sunny spot with well-drained soil. Incorporate organic material and fertilizer as needed.

Lady bird Johnson bluebonnetlate september 2013 Promotion

‘Lady Bird Johnson Royal Blue’ is an addition that accompanies ‘Abbott Pink’ (1993), ‘Barbara Bush Lavendar’ (1994) and ‘Texas Maroon’ (2000) as outstanding color variants of the Texas

native bluebonnet selected by Dr. Jerry Parsons and his cooperators. This striking cobalt blue color was derived from an isolated planting of another possible new color of red bluebonnets in 2006, selected originally from a ‘Texas Maroon’ bluebonnet field. Cobalt blue flowers were selected for two more years until a pure (>99%) cobalt blue-flowered population was obtained. ‘Lady Bird Johnson Royal Blue’ has all the other growth characteristics of the native Texas bluebonnet and can be grown from seeds or transplants. m

newsbites2012 Census of Agriculture Due February 4thTHe 2012 CenSuS of Agriculture forms were mailed to over 3 million U.S. agricultural producers during the last week of December. In Texas, about 375,000 Census forms were mailed. The mailings include all known farmers, ranchers, and agricultural producers, plus a large number of potential agricultural producers.

What is the Census of agriculture? The first Census of Agriculture was conducted in 1840, and is now conducted every five years. It is a complete count of U.S. farms, ranches, and operators; it looks at land use and tenure, operator characteristics, production practices and economic information. The Census serves as a very important “voice” for America’s farmers and ranchers.

Why is the Census of agriculture important? The Census provides the only source of uniform, comprehensive and impartial agricultural data for every county in the nation. Through the Census, producers will show the value and importance of agriculture in their county and can help influence decisions that will shape the future of American agriculture.

Who uses the Census of agriculture data? Census data are used by all who serve farmers and rural communities: university research and extension, state and local officials, agribusinesses, farm organizations, commodity groups, and many others.

Companies and cooperatives use the facts and figures to determine future locations of facilities that will serve agricultural producers. Community planners use the information to target needed services to rural residents. Legislators use Census statistics when shaping farm policies and programs. Producers use the information in making plans for future operations.

other uses of Census information: •Usedtoallocateblockgrantdollarstostates•Usedtoallocatefundsforbeginningfarmer,conservationand

other programs• Usedtohelpidentifyresearchprioritiesandtoallocatefundsaccordingly• UsedinruraleconomicdevelopmentlikebroadbandInternetexpansion

I’m retired or I’ve never farmed, do I need to return the Census form? Yes. Everyone who receives a Census form is required to return the Census form, even if they no longer farm or have never been involved in agriculture. A simple note of explanation on the front page will suffice. Please note: retired operators who own land enrolled in CRP or WRP are counted as farms and should complete the Census form.

I only have a small operation, do I count? Yes. It only takes $1,000 worth of agricultural production to be counted as a farm. A few cows, several goats, laying hens for local egg sales, some hay production – it doesn’t take much to be a farm. Everyone should complete and return their Census form.

Other Key Points:THe CenSuS of Agriculture has mandatory reporting authority, just like the population Census. This is due to the tremendous value of the information and because of the large amount of funds and resources targeted and allocated based on Census results.

Individual information is guaranteed complete confidentiality by federal law, Title 7 of the U.S. code. Title 7 prevents NASS from sharing individual information with any other government agency and also gives NASS immunity from any type of mandatory disclosure of individual data, including legal processes and FOIA.

NASS is restricted to publishing only aggregate totals at state and county levels such that the identity of any individual is not discernible in the published totals.

The form is lengthy, but there are many commodity specific sections for which producers will simply check “No”, because they do not raise those items.

There is a toll free phone number on the front of the Census form for anyone with questions: (888) 424-7828. NASS will operate calling centers from 7am to 9pm on weekdays and from 8am to 4pm on Saturdays, to respond to incoming calls.

For additional information about the Census of Agriculture, please

"MUST SEE" THEEVENT OF THE YEAR


T n l a g r e e n

IJune, I attended the annual Southern Garden History Society meeting in Richmond, Virginia. For one of the meeting’s tours we visited Thomas

Jefferson’s boyhood home, Tuckahoe Plantation. I couldn’t help but notice that the gardens contained modern pink Knockout roses, which seemed out of place at a 300-year-old property. I have nothing against this tough and beautiful rose, but unfortunately, like red tip photinias of yesteryear, Bradford pears of yesterday, and loropetalums of ten minutes ago, Knockouts are becoming landscape features ad nauseam. Knockout roses are great roses, but when every landscape under the sun contains only one variety it gets boring, not to mention setting the scene for another devastating disease adaptation.

A better option for the historic plantation would have been China roses (Rosa chinensis), which would have been prevalent at the time the plantation was active and therefore much more apropos. Period landscapes containing historically accurate period plants and designs lend a feeling of historical accuracy to plantations

and cottages alike. The inspiration of tourism and travel is to see something different. What’s the charm in visiting Wal-mart or McDonalds on your vacation?

Most people would think of porcelain upon hearing of a China rose, but the informed gardener should think of a perpetually beautiful, tough as nails plant. Many rosarians don’t realize it, but the China rose (Rosa chinensis) is the parent of all modern roses and was essentially a Southern knockout long before its time. Although not cold-hardy in the North, they are uniquely adapted to the South as disease-resistant shrub roses, without the patents and colored pots.

Brought out of China in the 1700s, the China rose was entirely different from any rose known at that time. Its most amazing aspect was its ability to repeat bloom. At the time, there were no ever-blooming roses in the West. China had them nearly a thousand years in advance.

In addition to its constancy of bloom, the China rose also possessed other unique characteristics, including pointed buds, purplish-red new growth, and blossoms that actually grew darker with age, as opposed to fading in bright light as existing roses did.

The original wild China rose (Rosa chinensis spontanea) was not discovered in China until 1885. This was a climbing, single-flowered, once blooming red rose. Either through sporting or hybridization over time, it eventually gave rise to dwarf ever-blooming shrubs.

It is now assumed that the original China roses were hybrids between the China rose

(R. chinensis) and the tea rose (R. odorata). The two “original” China roses in Europe were Slater’s crimson China, the first true red rose, and Parson’s pink China, also known as Old Blush because of its darkening petal color.

Slater’s crimson China is the original parent of all modern red roses. Old Blush is apparently the parent of the Portland class, the bourbon class, the

noisette class and possibly others. The China rose is also the parent of hybrid tea roses, polyantha roses, miniature roses, and even Knockout roses. What a lineage!

In a testimony to their survivability and duration, Old Blush and other China roses are among the most common vernacular garden roses in the South. That’s amazing for roses depicted in Chinese silk screen paintings 1,000 years ago.

It’s a shame to think that for all the China rose has contributed to our modern roses, it is now largely forgotten and neglected by the modern rose world as a useless relic of rose history. The China rose’s obscurity partially emanates from it being somewhat cold tender and normally freezing above the Mason-Dixon Line. Therefore, you seldom see China roses extolled in any garden literature from the North. Modern shrub roses were developed for the North. The China rose belongs to the South.

In fact, of all the antique roses existing today, I rank China roses number one for landscaping purposes. China roses prefer full sun and good drainage. They also benefit from the incorporation of organic material into the soil, mulching, deep infrequent watering, and a spring application of fertilizer. As they bloom on all new growth, China roses love an occasional shearing with the hedge clippers but never heavy pruning as with hybrid teas. They even tolerate regularly shearing into boxed hedges.

Also, remember that China roses are twiggy shrubs, not producers of cut flowers, and only possess a mild fragrance. Additionally, they can suffer from occasional bouts of powdery mildew during the winter and spring and from mild rounds of black spot during the summer. They, however, do not require any spraying to revive them. Some of the China roses that perform well in the South include Ducher, Old Blush, Cramoisi Superieur, Louis Phillipe, Martha Gonzales, Archduke Charles, and Mutabilis. In all honesty, I haven’t seen a true China rose that hasn’t performed well in the South. In this case, an antique “made in China” is a good thing. m

How Patient Should You Be With Impatiens Downy Mildew?

by Kevin Ong, PhD

Kevin Ong is an Extension Plant Pathologist and

directs the Texas Plant Disease

Diagnostic Lab at Texas A&M in College Station.

Impatiens downy mildew was in the news in the summer and fall of 2012 when this disease became an epidemic and showed up in multiple

states including Texas. The occurrence of this pathogen, Plasmopara obducens, is not sudden. This disease can devastate Impatiens walleriana plants rapidly and has been reported sporadically since 2004 in the US. But in the summer of 2011, outbreaks were reported in landscape and container plantings in the northeast US. Then in January of 2012, an outbreak of impatiens downy mildew was reported in landscape beds and in the greenhouse in south Florida. Subsequently it was found in many other places, particularly the eastern US. In Texas, the Plant Clinic began getting some reports in April of 2012 and it was confirmed in early May 2012. This disease was found in the landscape, greenhouse and retail situations. This disease can infect all varieties of I. walleriana. It can be a devastating disease that results in defoliation and eventual death of plant, so much that I am getting the sense that a number of growers in Texas

are considering not growing any or reducing the number of impatiens for the upcoming season.

What do we know about the Impatiens downy mildew pathogen?Plasmopara obducens is a water mold aka Oomycete. It requires moisture to make spores and to cause new infections. Typical conditions that favor the development of impatiens down mildew include cool temperature (average mean ~60 ˚F), wet foliage and moist air. Symptoms tend to show up after a prolonged period of high moisture (rain or humidity).

Like its other relatives in the class Oomycete (Pythium and Phytophthora), Plasmopara obducens produces numerous zoospores (swimming spores) in sporangia. There is concern that the sporangia may be disseminated over long distances by storms. However, it is more likely that spread would occur locally through splashing rains (water), overhead irrigation, tools/equipment or handling of

infected plant material. There is also concern about the persistence of this pathogen. P. obducens is capable of making oospores, that can survive in plant debris and may serve as inoculum for future plantings. It is believe that the oospore can survive in the soil for several years.

What does it look like?Initial symptoms include mild yellowing and/or stippling of the leaves. If conditions are conducive and disease has progressed, the underside of those symptomatic leaves will have a fuzzy soft “downy” growth. As the disease progresses, defoliation occur resulting in a “naked” stems appearance. Eventually, those stems will collapse and rot. (See photos)

How to take care of the plants? Management of this disease is probably easier in a greenhouse environment than in the landscape environment. During the production of the impatiens, constant monitoring and preventative fungicide plan can be effective. It should be noted that this disease is difficult to control after symptoms are observed. Symptomatic plants and fallen plant parts should be removed, isolated and destroyed. Rouged plants should be bagged and sealed prior to the dumping. Do not put infected plants in a cull pile or compost pile where it can continue to sporulate.

It is more difficult to manage this disease in the landscape because once symptoms are noticed, it is only a matter of time before the entire plant collapses. Furthermore, in nature, there is always the possibility of spores/sporangia blowing in from a distance away. And previous incidence of this disease in the particular bed/garden may result in the oospores being present in the soil – having the ability to cause new infections the following year. For the landscape, frequent monitoring is advised with prompt removal of infected plants. Preventative fungicide treatment may be possible, but may not always be practical. Also, planning and use of fungicide must be deliberate to avoid development of fungicide-resistance in the pathogen. m

Capitol Perspectives

Back in the Trenchesby Jim Reaves

On January 8, 2013 the Texas Legislature will convene for 140 days to take up the State’s business. The only legislation that the Texas

Constitution requires to be passed is the biannual budget. That being said, thousands of bills are filed each and every Legislative Session. Bills Filed: 2010 – 5,796; 2008 – 7419; 2006 – 6,190. The rate of filing for the 83rd Legislative Session seems to be at a lower rate.

Each session, TNLA tracks hundreds of pieces of legislation and supports, opposes or amends around 50 of them. This Legislative Session, TNLA staff will be at the State Capitol night and day, protecting the nursery/landscape industry from direct attacks and even the unintended consequences of some legislation.

TNLA will be spending a majority of our time working on the water issue and legislation that would have a negative effect on your business. We look out for immigration legislation that is anti-business, attempts to adjust the margins tax, right-to-capture groundwater, and many others. TNLA will focus on our memberships needs as they arise.

This year, I will continue to send out a legislative updates every Friday throughout the duration of the Legislative Session. If you are a member of TNLA, I will be happy to address any comments or questions you may have, even if it is legislation that affects you and not your business.

Rest assured that when it comes to legislative advocacy and regulatory monitoring, our leadership extends beyond the building. My service on several boards and committees keeps us active with the people and issues that affect you and your ability to do business in Texas. The Texas Agriculture Council, Texas Water Smart Coalition, Texas Employers for Immigration Reform, Texas Invasive Plant & Pest Council, and Texas Turf Irrigation Association are just a few of the groups where TNLA has a formal presence, and our reach is growing all the time.

I look forward to working my fourth Legislative Session for TNLA. As your Director of Legislative & Regulatory Affairs, feel free to email me at any time: [email protected] m

Jim Reaves is TNLA Director of Legislative

and Regulatory Affairs. He serves on

numerous boards and committees

including the Texas Agriculture Council,

Texas Turf Irrigation Association, Texas

Employers for Immigration Reform,

and Texas Invasive Plant & Pest Council.
