Mealybugs infiltrate greenhouses as tiny first-instar crawlers, easily hitching a ride on plant structures, tools and worker clothing — making eradication a persistent challenge. No current strategy fully eliminates mealybugs, largely due to gaps in species identification and their resilience against control measures.

However, infestations can be managed at an optimal level through precise species identification and a strategic approach that considers overlooked factors and the efficacy of available insecticides.

Discover mealybug control tips for greenhouses using chemical efficacy data and proven insecticide strategies in this article from Zee Ahmed, Ph.D., an assistant professor at Clemson University's College of Agriculture, Forestry & Life Sciences, and two Ph.D. students, Powlomee Mondal and Peilin Tan, in Ahmed's Turf and Ornamental Lab. Their research focuses on diagnostic tools and control strategies for managing mealybugs in greenhouses:

Our July issue is out now! Learn more about our cover story:

Myron Knobloch of Knobloch's Greenhouse is no less vigilant or watchful of potential disaster than any other grower. How could he not be? He has 2 acres under cover — about 33 greenhouses — producing 90% of the plants he sells out of his retail store.

But Myron could never have foreseen, nor would he have dared to imagine, that the biggest threat to the business he built hand-in-hand with his wife, Beth, would be her sudden passing due to an aggressive and devastating glioblastoma in 2015.

Beth had been the business manager. Where her husband knew plants and how to grow them, she knew numbers and how profits played into production schedules. But a week after the seizure, she came out of brain surgery unable to speak at all or communicate complex subjects. Five months later, she was gone.

Myron and his five children faced a world without a wife, a mother and a business manager. It was a tragic loss for the family and a huge blow to the business.

It was an uncertain time for the then-54-year-old grower-retailer. But among his five children, there were three sons who would become the future of Knobloch’s Greenhouse. The only question was how to get there.

The trio of sons and a solid succession plan developed with PivotPoint Business Solutions have kept the business growing and certain of a long future:

The gardening boom of the pandemic years was undeniable, but in hindsight, it was also unsustainable.

At some point, the pandemic had to end, bringing people back to their regular rhythm. Nearly half a decade from the peak of COVID, it has become clear that gardening behaviors are leveling. But that doesn’t mean that the industry is looking at a decline. More likely, it’s looking at a new normal.

We talked with reps from Axiom Marketing, Monrovia and The Garden Media Group and found out that even though gardening activities and sales have plateaued or seen marginal retreats, they remain higher than pre-pandemic levels.

So, what’s driving those that have stuck with gardening post-pandemic? What are they looking for from growers and plant brands, and what kind of trends are emerging in their outdoor spaces? The answers are enlightening and crucial to the future success of the industry:

In our 2025 Greenhouse Climate Control Research Report, sponsored by Ludvig Svensson, we surveyed more than 100 growers to find out where they’re growing, what they’re growing and the methods and challenges of controlling the most micro of microclimates within their operations.

They reported a constant concern with heat and puzzling over the ability to ensure a variety of plants grow optimally under the same roof.

We know you're under pressure to lower operating costs and stay competitive in today’s dynamic market as you work to produce high-quality, low-cost crops.

Apart from labor, energy is probably the top operating cost for most growers. So, one of the best ways to help reduce costs is to improve the energy efficiency of your operation.

Daniel Ciolkosz, an associate research professor at Penn State College of Agricultural Sciences, shares some of the most common successful measures greenhouse growers can use to reduce energy use without compromising the performance of your greenhouse:

Fireworks aren't the only thing booming — gardening is, too, according to new research from The Garden Media Group 🎆

While other industries report slowing traffic and declining sales, gardening is holding strong — and growing — despite cold weather, consumer caution and tariff-fueled economic anxiety.

Even with poor early spring weather, garden center sales in 2025 are only 3.9% behind 2024 and still far ahead of the same period in 2020.

“Gardening has always been recession-resistant,” says Garden Media Group President Katie Dubow. “In 2008, 2020 and now again in 2025, we’re seeing a familiar pattern. When people face financial or emotional uncertainty, they return to their roots — literally.”
