 Rafia Khan, Ph.D. Assistant Professor and Extension Specialist Texas A&M AgriLife Research and Extension Center, Overton, TX Winter can feel like a break from pest pressure, but for nursery and greenhouse growers, many insects are still present and waiting for the right conditions. Protected structures, mild winter weather, and overwintering life stages allow many pests to survive on plants, in pots, in growing areas, in debris, and in weeds. If these pest populations are not addressed, they often resume early and aggressively in spring. Common winter pests include aphids, thrips, mealybugs, scale insects, whiteflies, spider mites, and greenhouse moth pests such as the European pepper moth. These insects can survive on plant material, in potting media, or within greenhouse structures, often going unnoticed until populations increase. Programmed scouting remains the foundation of winter Integrated Pest Management (IPM). Monitoring efforts should be focused on current in-house plants and newly arrived plant material. Inspect leaf undersides, stems, and growing points, and use sticky cards to detect flying insects early. Cultural practices play a key role in reducing pest pressure during winter. Sanitation, such as the removal of plant debris, leftover shipped plants, weeds, volunteer plants, and unused containers, should be removed from the production sites as they may harbor pests. Manage irrigation carefully to avoid conditions favorable for fungus gnats and root pests, and inspect incoming plants before placing them into production areas. When treatments are necessary, applying products strategically and rotating insecticide modes of action helps protect product performance and avoid costly resistance issues. Winter is also the best time for growers to step back and evaluate what worked and what didn’t during the past season. Reviewing pest records, adjusting management plans, and training employees to recognize early pest signs can pay off quickly. Investing time in winter pest management reduces carryover populations, improves plant quality, and helps operations enter spring with fewer surprises and lower control costs.

Each year, the Lone Star Hort Forum brings together leaders from across the Texas green industry to step away from day-to-day demands and focus on what matters most: people, leadership, and the future of our businesses. This year’s Forum did exactly that — through honest conversations, practical learning, and moments that reminded us why this community matters. Day One: Grounded Perspectives and Practical TakeawaysDay One focused on real-world challenges and tools leaders can take back to their teams right away  We kicked off Day One with a familiar and trusted voice. Charlie Hall, a long-time Lone Star Hort Forum contributor, returned with his annual economic forecast — helping attendees better understand where the industry stands and how to plan for the year ahead with clarity and realism. From there, the day moved into sessions that resonated deeply with attendees because they addressed real challenges leaders are navigating right now:
A Special Highlight: Women in Horticulture One of the most impactful conversations of Day One took place during the Women in Horticulture session, which focused on how internal triggers affect leadership, communication, and workplace dynamics. The session explored a simple but powerful concept: our thoughts influence our feelings, which influence our actions — and ultimately our results. Attendees walked away with practical strategies to:
It was a thoughtful conversation that extended well beyond the room and reinforced the importance of self-awareness in leadership at every level. Live Podcast Recordings — Now Available Throughout the day, several live podcast conversations were recorded on-site and are now available to listen to at no cost:
Day Two: Celebrating Excellence and Learning From Each OtherDay Two began with the TNLA Awards Festival, where the community came together to recognize peers, celebrate excellence, and honor those who have helped move the industry forward. Honorary Lifetime Membership Award Winners: This year’s Festival carried special meaning as we honored Jim Reaves, a former TNLA staff member who passed away in August. Jim was posthumously awarded an Honorary Lifetime Membership, recognizing his lasting contributions and the impact he made on the Association and the people within it.

Scott Evans TMCNP, TCLP of Rancho Encino, FEWA & Native Jump Start Industry & Emerge Tours In the afternoon, attendees headed out on the Industry Tour and the Emerge Tours. These tours offered behind-the-scenes looks at real operations and real conversations, the kind that don’t happen in a classroom. Discussions on the bus, on-site, and face-to-face allowed participants to learn directly from peers about how they’re solving challenges and running successful businesses. A sincere thank you to our tour stop hosts for opening your doors and sharing your time and insight with our members. Day Three: Investing in Leadership and the Future The Forum concluded with the graduation of TNLA Leadership Bootcamp Class V, a milestone that represents months of learning, reflection, and personal growth.  Leadership Bootcamp is about more than professional development, it’s about building self-aware, confident leaders who are prepared to guide teams, navigate change, and contribute meaningfully to the industry. We are proud of this class and grateful for the perspective and energy they bring to the Texas green industry. The Forum closed with a forward-looking keynote, “Smarter, Faster, Stronger: How AI Can Future-Proof Your Nursery & Landscape Business,” reinforcing the importance of adaptability, curiosity, and thoughtful adoption of new tools. Why Lone Star Hort Forum Still Matters Lone Star Hort Forum isn’t about checking a box or attending another event. It’s about creating space — space to listen, reflect, learn from peers, and reconnect with why we do this work. Seeing the community show up for one another — in conversations, in recognition, and in shared experiences — is always why we do what we do. Thank you to everyone who joined us and helped make Lone Star Hort Forum 2026 meaningful. Special thanks to all our wonderful sponsors  On December 31, the U.S. Departments of Labor and Homeland Security announced plans to make 35,000 additional H-2B visas available for fiscal year 2026, on top of the 66,000 visas already authorized by Congress each year. The agencies have indicated these supplemental visas will be released through a temporary final rule, with details expected in the coming weeks.
This is welcome news for seasonal employers, but it’s important for TNLA members to understand both what this announcement does and does not address. The Administration confirmed it will use its congressionally granted authority for FY 2026 to release the 35,000 supplemental visas. That number is significantly lower than in recent years, representing roughly a 50 percent reduction compared to the supplemental visas made available in fiscal years 2023 through 2025. The Administration has also indicated that these visas will be targeted toward what it considers critical infrastructure sectors, including forestry, hospitality, tourism, transportation, manufacturing, and related industries. Many green industry businesses could fall within or support these sectors, but the exact eligibility requirements, filing timelines, and worker restrictions have not yet been released. Those details will come once the temporary final rule is published. Even with this announcement, the H-2B program remains heavily oversubscribed. The first-half cap for fiscal year 2026 was reached on September 12, and the second-half cap is expected to be reached quickly. Without a timely release of the supplemental visas and potentially further action by Congress, many seasonal employers will continue to face workforce shortages that directly affect their ability to operate. As TNLA has outlined in its advocacy efforts, the H-2B program is already costly and highly regulated. Employers must recruit U.S. workers, pay premium wages, secure approvals from multiple federal agencies, and comply with strict program requirements. The workers themselves are temporary and seasonal, and they return home at the end of the season. They are not immigrants. For many businesses, access to H-2B labor is what allows them to meet peak demand, keep year-round American employees working, and avoid turning down work or cutting services. For the green industry, lack of access to H-2B labor often means delayed projects, reduced services, higher costs, and lost contracts. Research shows that each additional H-2B worker supports multiple full-time U.S. jobs, including supervisors, drivers, logistics staff, and administrative employees. When labor shortages persist, businesses are forced to scale back operations, putting American jobs at risk and increasing costs for customers. TNLA continues to press both the Administration and Congress to move quickly. This includes urging the Administration to promptly issue the temporary final rule allocating supplemental visas for FY 2026, encouraging Congress to retain seasonal employer protections in the FY 2026 DHS appropriations process, and continuing to push for longer-term cap relief that provides predictability and stability for responsible employers. We are actively using these points on Capitol Hill and in ongoing conversations with federal agencies to advocate for the full scope of the green industry. As more details become available, TNLA will continue sharing updates and practical guidance so members are prepared to act.

Rafia Khan, Ph.D. Assistant Professor and Extension Specialist Texas A&M AgriLife Research and Extension Center, Overton, TX Texas A&M AgriLife Extension is working on publishing a series of educational articles to assist homeowners and green industry professionals in recognizing and managing two recently confirmed invasive insect pests in Texas: the two-spot cotton leafhopper (Amrasca biguttula) and the short-spined thrips (Thrips parvispinus). These pests pose emerging risks to ornamental plants by affecting plant health, appearance, and market value.
The planned articles will provide clear descriptions of pest identification and injury patterns to support early detection. Feeding by the two-spot cotton leafhopper causes a condition known as “hopperburn,” characterized by leaf curling, yellowing, bronzing, reduced vigor, and, in severe cases, plant death. This pest attacks a wide range of ornamental hosts, including hibiscus, and is often difficult to detect due to its small size and concealed feeding behavior. Short-spined thrips are tiny, highly polyphagous insects that feed on numerous ornamental crops, including annual bedding plants and tropical ornamentals. Their feeding leads to foliar scarring, distorted shoots, flower drops, and stunted growth, resulting in reduced plant quality and marketability. In addition to injury symptoms, the articles will summarize current regulatory actions, including quarantine measures and inspection efforts implemented by regulatory agencies to limit pest movement and spread. Management options discussed will be based on science-based recommendations developed from research conducted by other researchers and institutions, with an emphasis on integrated pest management (IPM) strategies such as monitoring, sanitation, cultural practices, and targeted chemical controls when necessary. Through these publications, Texas A&M AgriLife Extension aims to improve awareness, encourage early reporting, and promote informed decision-making. By providing timely, research-informed guidance, Extension seeks to help homeowners and professionals reduce the impact of these invasive pests and protect the long-term sustainability of Texas landscapes and ornamental production systems. The Texas Nursery & Landscape Association recently helped bring a congressional district tour to Brazos Citrus Nursery in West Columbia, about 60 miles southwest of Houston. The nursery is owned and operated by George Shackelford, a second-generation citrus grower who also serves on the TNLA Board of Directors, and the visit included staff from Congressman Troy Nehls’ office who came out to see firsthand how citrus is grown and managed here on the Gulf Coast. Background: The Place, the People, and the IssuesGeorge Shackelford and his wife, Leah, welcomed everyone with coffee and donuts and took time to share the family history behind the nursery and what makes their operation unique   The conversation covered challenges that growers across the green industy are dealing with every day, including:
The Tour The tour kicked off by hopping into George’s truck and heading out to several greenhouses on the property. Before anyone stepped inside, staff got their first surprise: a decontamination chamber, where they were lightly sprayed with a human-friendly sterilization solution to prevent the spread of disease.
From there, it was through a series of double doors and powerful fans designed to keep any outside contamination from entering, followed by an overhead door for extra precaution. George explained that these steps may seem intense, but they’re necessary to protect young citrus trees. Inside the greenhouse, staff were met with rows of beautifully manicured three-gallon citrus trees, lined up neatly and thriving. George walked everyone through the careful, step-by-step process he follows to make sure every tree meets the highest standards before it ever leaves the nursery. One detail that caught the congressional staff’s attention: citrus trees in his nursery don’t see direct sunlight until they’re ready to be transported to market, a testament to just how controlled and intentional the growing process is.
As the tour continued across the property, it became clear just how much planning, precision, and hands-on care go into producing healthy citrus trees, long before they ever reach a customer. The Shackelfords  From the moment you meet George Shackelford, it feels less like a business visit and more like stopping by a family member’s place. He has a genuine, down-to-earth way about him that immediately puts people at ease. That humility is matched by a deep understanding of the citrus industry and an ability to adapt as the business and regulations change. By his side is his wife, Leah, who keeps a close eye on the financial side of the business and knows exactly how the operation is performing. Together, they make a strong, well-balanced team. George also serves on the TNLA Board of Directors, representing growers and bringing their perspective to the table. While citrus is the heart of the nursery, George also works in bamboo and other fruit as a wholesaler. A walk around the property reveals a few surprises as well, including exotic deer and well-fed cattle. The cattle actually started as a school project for their daughter, who decided she wanted to show cattle. George admits he questioned it at first, but today he has no regrets.  Why District Tours Matter District visits like this are a critical part of TNLA’s advocacy strategy. They allow policymakers and staff to see real businesses, hear directly from our members, and better understand why science-based policies matter for the green industry. George’s resilience and commitment to Texas agriculture shows the dedication required to operate in today’s environment.
