Is it just me, or is this semester flying by? 🍂 Hard to believe we are already halfway through the semester, with Thanksgiving and Christmas just around the corner! I guess time really does fly when youre having fun and love what you do! And speaking of fun, heres another little glimpse into our HORT 201 classroom at Texas A&M University Department of Horticultural Sciences! Last week, we welcomed Dr. Lukas Hallman from UF IFAS Horticultural Sciences Department, University of Florida/IFAS Indian River Research and Education Center for a guest lecture on Florida citrus, bringing a little Sunshine State flavor to Aggieland! 🍊👍 One of my favorite parts of teaching is connecting students with people who bring real-world experiences, different perspectives, and a genuine passion for horticulture into our classroom. Thanks again, Lukas, for spending time with our Aggies!

This past week in HORT 201, we explored the importance of temperature and chilling requirements in distinguishing temperate, subtropical, and tropical horticultural crops. We concluded the module with a guest lecture from Dr. Lukas Hallman of the UF IFAS Horticultural Sciences Department, and located at the University of Florida/IFAS Indian River Research and Education Center. Dr. Hallman discussed the unique physiology of citrus as a subtropical crop and helped the students connect concepts such as temperature, growth, and development with the realities of commercial production. He also shared insights into one of the greatest challenges facing the citrus industry: citrus greening (HLB) and its profound impact on production. A big thank you to Dr. Hallman for sharing his expertise and experiences with our students! Bringing science and practice together in the Texas A&M University Department of Horticultural Sciences.

Bringing Florida citrus to Aggieland! Every semester in HORT 201, we welcome an out-of-state guest lecturer to expose our students to national horticultural problems. Next week, we’re excited to welcome Dr. Lukas Hallman from the University of Florida/IFAS Indian River Research and Education Center UF IFAS Horticultural Sciences Department! He’ll share the story of the Florida citrus: from an iconic industry to the devastating impact of HLB (citrus greening) and the research and innovation helping growers fight back. 🍊🌱 Welcome to Aggieland, Dr. Hallman! 👍

Busy Day 3 at the American Society for Horticultural Science Annual Conference! Two presentations highlighting the pedagogy and experiential learning approaches we use in HORT 201 and HORT 202. Also presented a poster showcasing our work on PFAS and nanoplastics in pecans and grapes, and graduate student Andrew McFarland presented his research on phenotyping grape varieties under salinity stress. The day concluded with the undergraduate poster competition, where Madison Quiroz presented her research on nanoplastic uptake in cilantro. The evening was just as rewarding. I had the opportunity to reconnect with former friends and colleagues from the UF IFAS Horticultural Sciences Department, attend the Texas A&M University Department of Horticultural Sciences happy hour, and wrap up the day with a steakhouse dinner alongside former, current, and teaching assistant students. One last day to go!

Day 2 at the American Society for Horticultural Science (ASHS) Annual Conference has been outstanding! The opening ceremony and plenary lecture set a great tone for the meeting, and the Career Fair was full of energy with excellent conversations between students, faculty, and industry professionals. One of the highlights of the day was reconnecting with colleagues and meeting new members of the horticultural community.
The welcome reception was truly memorable. Country music, line dancing, and two-stepping created a fun Texas atmosphere and made for one of the best conference receptions I've attended. WHOOP! Today is packed with teaching sessions and poster presentations, and I'm looking forward to learning from colleagues who continue to advance horticultural education and research.

Day 1 at the American Society for Horticultural Science is off to a great start! We kicked things off by exploring two North Texas vineyards: Square Cloud Winery and Eden Hill Winery, and enjoying a w**e tasting, followed by a visit to the Dallas Arboretum and Botanical Garden. The day wrapped up with a nice dinner showcasing the best of Texas horticulture.
Looking forward to more presentations and connecting with colleagues.

🍇💧 Just wrapped up a really nice Vineyard Water Management Workshop at Texas A&M AgriLife Research and Extension Center in Lubbock, TX!
Big thanks to Dr. Patrick O'Brien for putting together such a nice program. It was great to see so growers, students, along with colleagues from Texas A&M AgriLife Extension Service, Texas Tech University, and Texas A&M University Department of Horticultural Sciences.

I really appreciated the interactions, learned something new, had the opportunity to showcase our research, and hopefully planted the seeds 🌱 for some new collaborations.

🔥 Hot off the press! I am excited to share our new open-access publication: “Physiological Responses of Scion and Rootstock in Grafted Grapefruit Trees under Salinity Stress” This research was completed by Dr. Neus Alcón Bou, former Ph.D. student in my lab at the UF IFAS Horticultural Sciences Department, based at the University of Florida/IFAS Indian River Research and Education Center. The paper is presented as a collaborative effort with the Texas A&M University Department of Horticultural Sciences, bringing together colleagues with expertise in citrus physiology, irrigation, and salinity management. Our findings show that salinity tolerance depends on selecting the right scion-rootstock combination, not simply the rootstock alone.

I can hardly believe I’m saying this: the HORT 202 Horticultural Science and Practices Laboratory textbook is undergoing its final checks and is headed to print! This has truly been a team effort. I am especially grateful to Jacob Muras and our outstanding teaching assistants, whose hard work and ideas helped bring this manual to life. Across 15 weeks and 15 hands-on labs, students will explore taxonomy, plant reproduction, drought, salinity, hydroponics, LED lighting, soil composition, and much more.

The manual is dedicated to Dr. David Reed, whose commitment to HORT 201 and HORT 202 for more than 45 years inspired generations of students and laid its foundation.

Horticulture has been part of Texas A&M since its first class. Read my preface to discover more of that history, and consider becoming part of its future by majoring in horticulture or joining our Texas A&M University Department of Horticultural Sciences.

Thanks, and Gig ’em! 👍
