When growers and landscape professionals think about insects, the first thought is often pests and the damage they cause. However, not all insects are harmful. Many beneficial insects play an important role in naturally suppressing pest populations in greenhouses, nurseries, and landscapes. These “good bugs” are valuable partners in Integrated Pest Management (IPM) programs and can help reduce reliance on chemical insecticides. Beneficial insects are a key component of Integrated Pest Management (IPM) programs. They help suppress pests naturally and can improve long-term pest management success when properly conserved or introduced into production systems. Two important groups of beneficial insects are predators and parasitoids. Predators actively consume pests throughout their life cycle. Common examples include lady beetles, green lacewings, minute pirate bugs, predatory mites, and hover fly larvae. These natural enemies feed on aphids, whiteflies, spider mites, scales, thrips, and other soft-bodied pests commonly encountered in Texas greenhouses and landscapes. Parasitoids are specialized insects, usually tiny wasps, that develop inside or on a host insect and eventually kill it. Several parasitoid species are commercially available and widely used in greenhouse biological control programs, especially for whitefly and aphid management. Parasitoids are specialized insects, usually tiny wasps, that develop inside or on a host insect and eventually kill it. Several parasitoid species are commercially available and widely used in greenhouse biological control programs, especially for whitefly and aphid management. Greenhouse environments often provide ideal conditions for biological control because temperature, humidity, and pest populations can be monitored more closely. In landscapes and nurseries, conserving naturally occurring beneficial insects can also provide significant pest suppression over time. Unfortunately, beneficial populations are frequently disrupted by unnecessary or repeated applications of broad-spectrum insecticides. One of the biggest challenges in pest management is recognizing when beneficial insects are already helping control a pest problem. In some situations, professionals may apply insecticides before evaluating predator or parasitoid activity. This can eliminate natural enemies and create secondary pest outbreaks or pest resurgence. In addition, repeated use of the same insecticide groups can contribute to pesticide resistance, making future pest management more difficult. Scouting remains one of the most important tools in preserving beneficial insects. Correct identification of both pests and beneficials allows professionals to make informed treatment decisions. When insecticide applications are necessary, selecting reduced-risk or selective products can help preserve natural enemy populations while still managing key pests. Habitat also plays a role in supporting beneficial insects. Flowering plants, reduced dust, proper irrigation management, and minimizing unnecessary pesticide exposure can all encourage beneficial activity in landscapes and production systems. Biological control is not always a complete replacement for insecticides, but it is an effective management tool when incorporated into a broader IPM strategy. As greenhouse and landscape industries continue to face challenges from invasive pests, environmental concerns, and pesticide resistance, beneficial insects should not be viewed as forgotten tools. Instead, they should be recognized as valuable partners in sustainable pest management programs. Photo credit:
Rafia Khan, Ph. D. Assistant Professor and Extension Specialist Texas A&M AgriLife Research and Extension Center Overton, TX. Last week, TNLA traveled to Washington, D.C. alongside members of Texas’ green industry for the annual H-2B Fly-In. During the trip, TNLA members met directly with Congressional offices to discuss workforce challenges impacting green industry businesses across Texas. The conversations focused heavily on the seasonal H-2B VISA program. For many green industry businesses, these workers help keep projects on schedule during peak seasons while also supporting year-round American jobs within their companies. Why This Matters to Texas’ Green Industry Texas’ green industry continues to face significant workforce shortages, particularly during high-demand periods in the spring and summer. During our meetings in Washington, TNLA members had the opportunity to speak directly with Congressional staff about how these workforce challenges affect their businesses on a day-to-day basis. Members shared personal stories about trying to keep crews staffed during peak project seasons, balancing growing customer demand, and managing the uncertainty that comes with not knowing whether seasonal workers will arrive on time. Some discussed the pressure of meeting timelines for government and commercial contracts, while others explained how workforce shortages impact long-term business planning and growth. Several members also highlighted that dependable seasonal labor helps create opportunities for year-round American employees by allowing businesses to expand operations, invest in training, and move workers into higher-skilled positions over time. One of the most impactful aspects of the trip was ensuring policymakers heard directly from employers experiencing these challenges firsthand. What Was Discussed in Washington A major focus of this year’s advocacy effort was support for the proposed “Certified Seasonal Employer” language currently being discussed in federal appropriations negotiations. The Certified Seasonal Employer proposal is designed to reward businesses that have consistently followed the rules and responsibly used the H-2B program over multiple years. Under the proposal, employers that have received H-2B labor certifications for the past five years would be allowed to maintain access to the highest number of seasonal workers they were previously certified for without those workers counting against the annual H-2B cap. One way to think about it is this: businesses that have proven year after year they are compliant, dependable, and operating legally would no longer have to “re-enter the lottery” every season just to maintain the same workforce levels they have historically relied upon. Currently, the H-2B program has an annual visa cap of 66,000 per fiscal year that has not been updated in decades despite major economic growth and increased workforce demand. The proposed language would reward long-time, compliant employers (certified for the last five years) instead of forcing them to compete under the same uncertainty each season. These workers would not be included in the cap. Where the Language StandsThe Certified Seasonal Employer language is currently being discussed as part of the Fiscal Year 2027 Department of Homeland Security (DHS) Appropriations process in Congress. Rather than moving as a standalone immigration bill, the proposal is being pursued through the federal appropriations process because Congress frequently uses annual funding legislation to address operational H-2B issues and cap relief measures. In this case, industry groups are advocating for the language to be included in the baseline DHS Appropriations bill because DHS oversees key parts of the H-2B program, including visa allocation and administration. The proposal has already gained significant attention in Washington. According to industry briefings shared during the fly-in, the White House previously supported inclusion of the Certified Seasonal Employer language during earlier federal funding negotiations, and advocates are continuing to push for its inclusion in the final FY27 DHS funding package. This means the current focus is on educating Congressional offices, appropriations staff, and committee leadership about why workforce certainty is critical for seasonal employers and why long-time, compliant businesses should receive more predictability within the H-2B process. For TNLA members, the issue is not simply about increasing workforce numbers; it is about creating a more stable and predictable system that allows responsible employers to better plan projects, retain year-round employees, and continue supporting Texas’ growing economy. What Success Looks Like For TNLA members, success would mean:

What Landscapers, Builders, and Suppliers Need to Know San Antonio Water System (SAWS) is preparing to actively inspect soil quality under newly installed turfgrass—a requirement that has been in the city code for nearly 20 years but has never been consistently enforced. This is the first time we’re aware of a Texas water utility inspecting soil quality on single-family homes, and it could influence how other cities handle water-conservation rules in the future. TNLA is tracking this closely to ensure members understand what’s coming and how it may impact your projects in San Antonio and beyond. Why SAWS Is Doing ThisSAWS’ goal is straightforward: improve soil beneath sod so landscapes use less water over time. Better soil means:
What the Ordinance RequiresSan Antonio’s existing soil rule states that new turfgrass must be installed over at least 4 inches of soil, which must include a minimum of 0.25 inches of Soil Organic Matter (SOM). SOM may come from enriched topsoil or contractor soil mixes that improve structure and water-holding capacity. In short: sod must be installed on quality soil that can hold water and support healthy growth. This isn’t a new rule—this is new enforcement. TNLA’s PositionIn November 2024, the TNLA Board formally adopted a position supporting a minimum 4-inch soil depth in areas with water-conservation concerns. The science is clear: Healthy soil is essential for responsible water use and long-term landscape success. TNLA supports soil standards that:
Why This Matters Beyond San Antonio Because SAWS is the first Texas water utility to launch this type of inspection on single-family homes, other municipalities may look to this strategy as a model. This could influence:

Last week, TNLA hosted a webinar with Jeremy Mazur, one of Texas’ leading voices on water policy, to examine how Proposition 4 and other statewide initiatives could shape the future of our state’s water supply, conservation, and infrastructure. Proposition 4—on the ballot this November—would dedicate $1 billion per year from existing sales tax revenue to the Texas Water Fund producing up to $20 billion of new funding over the next 20 years.
Jeremy emphasized that while new funding tools are essential, Texas’ long-term water security will ultimately depend on sustained infrastructure investment and close collaboration among utilities, landscapers, growers, and irrigators. He highlighted the role TNLA members already play in leading the way—designing sustainable landscapes, advancing efficient irrigation practices, and advocating for balanced policies that promote both conservation and customer choice. 📺 Watch the full webinar here: https://youtu.be/lq-BuOC35qY 🎧 Listen to the full conversation here: https://tinyurl.com/bdfv6buk On April 2, 2025, new U.S. trade measures were announced that represent a major shift in federal tariff policy—with broad implications for the horticulture and landscape industries.
Before diving into the specifics, here’s a quick refresher: What Is a Tariff? A tariff is a tax placed on goods imported into a country. It’s designed to make foreign products more expensive, either to encourage consumers to buy domestically or to apply pressure in trade negotiations. Example: If your business imports $100,000 worth of garden tools from Italy and a 10% tariff applies, you would owe $10,000 in duties—bringing the total cost to $110,000. Who Pays for Tariffs?While tariffs are technically paid by importers at the border, the costs often get passed down the supply chain:
Key Changes TNLA Members Should Know 🔹 10% Blanket Tariff on All Imports Effective April 5, 2025, a 10% tariff will apply to all goods entering the U.S., regardless of country of origin. This is one of the most sweeping tariff measures in recent history. 🔹 Reciprocal Tariffs Begin April 9A second round of tariffs will target goods from countries that impose barriers on U.S. exports. These “reciprocal” tariffs will vary by country and industry. Exemptions include:
🔹 Canada & Mexico Impacts are limited for now under active IEEPA orders related to migration and fentanyl:
🔹 End of Duty-Free Imports from China & Hong Kong The de minimis rule currently allows duty-free shipments under $800. That exemption ends soon:
This change will significantly impact small package imports and e-commerce. 🔹 Auto & Auto Parts Tariffs A 25% tariff on imported cars takes effect April 3, 2025. A separate tariff on imported auto parts will follow no later than May 3, 2025. Parts that meet USMCA requirements are initially excluded. However, the Commerce Department will soon introduce a system to assess which components count as “non-U.S.” for tariff purposes. What TNLA Members Should Do Now If your business relies on imported goods—such as pots, fertilizer, hand tools, or machinery—it’s important to take proactive steps:
Why Labor Access Matters More Than Ever These new tariffs will likely increase your cost of doing business. That’s why labor policy must be part of the conversation. A reliable, legal workforce—especially through programs like H-2A and H-2B—is critical to absorbing financial pressure and staying competitive. Tariffs and workforce access go hand in hand. In a more expensive global marketplace, stability and productivity at home are non-negotiable. TNLA will continue to monitor these changes and advocate for solutions that protect and support your business. Stay tuned for updates. Honoring Women’s History Month
