Greenhouse & Nursery Diseases: Focus on Summer with Dr. Ann Chase & Dr. Aaron Palmateer

Greenhouse & Nursery Diseases: Focus on Summer with Dr. Ann Chase & Dr. Aaron Palmateer

June 28, 2022

In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined for the second time by Dr. Ann Chase, owner of Chase Agricultural Consulting, and Dr. Aaron Palmateer, technical development lead for the ornamental business at SePRO. Both are expert-level plant disease gurus with decades of combined work in the field.

Last time we talked with Ann and Aaron, the discussion centered on what to expect—from a disease perspective—in spring production. If you didn’t listen to that one, jump back in the archives and check out Episode 33. This time, we’re moving on to summer, but first, the guests reflect back on spring for a bit before jumping right into warm-season diseases like Phytophthora, Rhizoctonia, soft rots like Erwinia, Southern Blight, Xanthomonas and plenty more. They discuss what they’ve seen in greenhouses and nurseries already this summer and what they expect to see soon—more than 25 diseases they’ve seen first-hand. One of the most interesting parts of this cast is a rundown of common diseases and the temperature ranges that bring them on. The episode continues with thoughts on why producing crops (like vinca, poinsettias and fall pansies) out-of-season often requires the most vigilance and hardest work by production teams before concluding with an in-depth look at the most cutting-edge control strategies for summer diseases.

Control Your Inputs: Reduce Risk Through Growing Mix Selection

Control Your Inputs: Reduce Risk Through Growing Mix Selection

June 2, 2022

In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by two dynamic guests for a discussion that’s equal parts informational and instructional with a healthy dose of humor added to the mix. In relation to current supply chain challenges that are predicted to continue for some time, the importance of versatility and flexibility is as important now as ever and trialing to develop modern plans and backup plans plays a huge role in successful crop production. With growing media (especially peat) at the foundation of professional greenhouse production, understanding how you can take more control of your inputs and continue to create optimum quality plants is a critical component to your overall plan.

We’re lucky to have two experienced and creative guests join us this episode to share their thoughts, knowledge and advice to explore potential solutions for increasing crop quality, as well as efficiency. Pierre-Marc de Champlain and John Santoro from Berger are here to explain ways to ease supply chain burdens using creative growing mix selection and incorporating different media components in the correct way.

The discussion begins with the current supply chain, good and bad, and then moves on to why peat is not only the backbone of soil mix components but also a very viable option now and looking to the future. Get ready to hear all about why responsible bog management is at the forefront of Berger’s approach and why this is good for the entire industry. Pierre-Marc and John share their thoughts on why versatility is critical now more than ever and ways to fine tune your production by looking closely at your media mix. The episode wraps up with an explanation of the importance of trialing and creating a plan and backup plan related to growing media. Both of the guests have a lot of experience and unique takes on greenhouse production and I know you’ll find this episode engaging, informational and fun.

You’ll want to listen all the way to the end of this episode, because we cover a lot of topics that build to a comprehensive growing media strategy.

Dynamics of Growing Media (Part 3): Successful Analysis & Interpretation

Dynamics of Growing Media (Part 3): Successful Analysis & Interpretation

May 5, 2022

In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by Troy Buechel, a Horticulture Specialist with Premier Tech, for the final episode in a three-part series discussing the technical side of growing media. Now that we’ve worked our way through testing and sampling, it’s on to analysis. Looking at returned data from tests conducted on growing media, water and plant tissue can seem overwhelming but Troy is going to walk you through it.

This episode begins with a look into the most important numbers to consider when you see results from a test. From pH to EC and macronutrients to micronutrients, a lot can be gleaned when you understand what’s most critical. Knowing deficiencies can quickly lead to reversing the issues at hand and bringing your crop back to its potential.

Next, Troy discusses contaminants that can lead to plant stress, such as sodium chloride, and what this can mean to a crop. Clear results from testing are important before starting to correct problems. Next, the discussion turns to the ranges you want to see related to pH, EC, macronutrients and micronutrients. The conversation gets pretty in-depth and technical so feel free to pause the podcast, make notes and then hit play again.

Another topic of conversation in this episode is types of tests and ways they are conducted. Some can be done easily, in house, while others require the expertise of a lab. Troy helps make sense of this, so you choose the best path. This episode (and series) ends with some real-world stories and situations Troy has encountered over the years. As you listen, you might start nodding because as we all know, no grower or greenhouse is immune to common problems, or even the weirdest ones.

You’ll want to listen all the way to the end of this episode, because the information builds throughout! Special thanks to Troy and the folks at Premier-Tech (the company behind Pro-Mix Growing Media) for lending much-needed expertise to such an important topic.

Dynamics of Growing Media (Part 2): Effective Sampling

Dynamics of Growing Media (Part 2): Effective Sampling

April 20, 2022

In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by Troy Buechel, a Horticulture Specialist with Premier Tech, for the second in a three-part series discussing the technical side of growing media. Sampling is perhaps the most critical part of diagnostics and getting to the root of problems in your greenhouse. “Junk in, junk out,” as they say. An effective sample allows you or an independent lab to figure out the cause of a problem, while a poor sample isn’t worth much. It’s really all about consistency.

Troy and Bill start by going over what makes a consistent sample—cultivar, size, planting date, greenhouse block, etc. Sampling random plants from different locations and conditions creates a very muddy picture and stands in the way of an accurate analysis. But following some simple protocols can make the picture much clearer and the solution similarly straightforward. Next, they run through a detailed sampling process.

Troy then covers some dos and don’ts when it comes to sampling, as well as sharing some stories from the field. Sending a whole plant can lead to problems, as can sending wet samples. The last thing you want a lab to receive is a bag of mush. Troy talks you through all the steps to take. They wrap up with a conversation about protocols to follow to ensure a quick, useful analysis.

You’ll want to listen all the way to the end of this episode, because the information builds throughout! Stay tuned for episode three, coming soon, where Troy and Bill tackle successful analysis and interpretation, because testing and sampling are done with a goal in mind. The goal is data to use in decision making. If you missed the first part in our series, The Importance of Testing, jump back in the archives and check it out.

Dynamics of Growing Media (Part 1): The Importance of Testing

Dynamics of Growing Media (Part 1): The Importance of Testing

April 7, 2022

In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by Troy Buechel, a Horticulture Specialist with Premier Tech, for the first in a three-part series discussing the technical side of growing media. Assumptions and “trial and error” often lead to greater production problems, as well as wasted time money. Learn why proper testing of media, water and plant tissue is always the best bet, because without it, there’s no starting point in your mission to diagnose and correct issues.

Troy and Bill start by framing up the discussion by explain exactly why testing is important and should be done regularly, versus when a problem arises. Then, Troy begins the conversation by outlining the goals of testing—to establish trend lines related to pH, EC and nutrients to help paint a complete production picture. He details the parameters that should be tested, and when. Some can be tested twice a year (before spring and fall/winter production), while others need to be checked as often as weekly.

 

They spend a lot of time discussing testing tools, including the best types of pH and EC meters, because using bad tools that aren’t calibrated correctly is basically a waste of time. Before closing, Troy shares some real-world testing stories to highlight why these activities are so critical. Poor testing or no testing can lead to devastating results.

 

You’ll want to listen all the way to the end of this episode, because the information builds throughout! Stay tuned for episodes two and three, coming soon, where Troy and Bill tackle proper sampling and how to use returned results to make proper changes and get on a path to success.

Next Level Engagement, Growth and Brand Building

Next Level Engagement, Growth and Brand Building

November 15, 2021

In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by the dynamic Sam Kirkland, strategic relationship manager with Epicor Software Corporation to discuss how to leverage local messaging, technology and measurable programs to drive significant bottom-line growth. According to Sam, modern engagement strategies proving successful in garden center retail (and other industries) include community and local messaging, customer growth management and loyalty marketing. All of these pieces work together to generate dollars that go straight to the bottom line.

 

Sam and Bill start by looking at the tremendous growth the horticultural industry has seen in the past two years and why it’s important to support, retain and grow the new folks walking through garden center doors. They quickly move into tactical ways to market a business to drive loyalty and the importance of following a plan. Once plans and tactics are in place, it’s time to create key performance indicators and measurements to track your efforts. Sam has plenty of anecdotal and data-driven stories of how successful garden centers have approached this process using technology. As he says, “Now is the time to realize the benefits of all of your hard work.”

 

When you begin to think about customer loyalty as a driving goal, interesting information emerges. Your most engaged shoppers spend more and shop more often. They gravitate toward products you recommend, and they evangelize your business to others in the community. Often, they shop with you every season and view your store as their on-stop-shop for everything garden related. And they’re your most profitable group. You want more of them.

Structures Strategies: Build New or Refresh?

Structures Strategies: Build New or Refresh?

October 29, 2021

In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by Paul Golden, Sales Manager for Commercial Growing with Prospiant Inc., to discuss how you should approach the decision to build new greenhouses or retrofit or repurpose your current structures to meet new crop needs or prepare for product mix shifts in the future. They look at many angles this episode, from the physical structure and components inside to the people who work under the greenhouse roof. Your greenhouse structures serve diverse purposes and impact just about every factor in your business, including the health and success of each crop, as well as labor, efficiency and employee attitudes.

Through this podcast, Paul and Bill touch on all of these factors and more moving from the structural functionalities needed for your equipment to how your existing layout impacts labor and efficiency. One key factor to consider when deciding to build new or refresh is the cost of maintenance and Paul spends plenty of time on this. Perhaps shifting these expenses towards a new build is a better bet long term. The podcast concludes with a discussion geared toward hybrid business, grower-retailers. If you have plans to add a retail component to your business, due to increased demand in the past few years, you have a whole new set of considerations, beginning with the fundamental question: Is your greenhouse structurally sound? You also need to think about the shopping environment and whether your current facility is conducive to people with a far different tolerance for the greenhouse environment than your staff.
