Not Familiar with AFE’s Grow Pro Webinar Series? You Really Should Be!

While chatting with various growers and IPM technical reps this year, I realized some in Ontario aren’t familiar with the American Floral Endowment’s (AFE) Grow Pro Webinar Series. This is an excellent series that shares floriculture research funded by AFE, as well as other topics.

Previous webinars have focused on things like thrips and botrytis control, biostimulants, growing in reduced-peat substrates, and more.

A webinar I’ll recommend for January is one on oomycete pathogens, like Pythium and Phytophthora:

Ruh Roh, Root Rot! Managing Oomycete Pathogens in Floriculture Production

Speaker: Dr. Johanna Del Castillo, UC Davis
Tuesday, January 20th at 1PM EST
Oomycete pathogens remain a persistent threat in floriculture production, causing significant losses when conditions tip in their favor. In this webinar, Dr. Del Castillo will dive into the biology of Pythium and Phytophthora, how to diagnose root rot issues, and the most effective management approaches. Attendees will gain actionable strategies to improve root-zone health and reduce disease pressure in their operations. When you’re thinking “ruh roh,” it’s already too late—join us to get ahead of root rot and outsmart oomycete pathogens.

Common Issues and Practical Solutions: Disease Prevention & Crop Uniformity

Welcome to this blog series, where we will discuss common production issues and practical solutions you can consider implementing in your own greenhouse.

In this post, we’ll focus on preventing disease and increasing crop uniformity. We’ll discuss two key practices that can help both issues: selecting the right growing media and maintaining greenhouse sanitation. Small changes in these areas can reduce the risk of disease and shrink, while promoting more consistent growth across your crop and prevent things like plant stunting.

Throughout this post I’ll use Kalanchoe production as an example. Even if you are not a Kalanchoe grower, there will relevant information that you can apply to your own crops. Read on for more details.

Points for Points! Production Pointers for 2024 Poinsettias

This post was contributed to by Abigail Wiesner, Drs. Sarah Jandricic, and Chevonne Dayboll.

Christmas in July? Not quite, but poinsettias are making their way into greenhouses across Ontario, and they always arrive at the hottest time of the year.

Nutritional issues, environmental stress, PGR mistakes and early diseases can all be costly in this high-value crop. Read on for common pitfalls and how to avoid them, as well as links to pest management information in early production.

How-to Video of the Week: Greenhouse Sanitation

Now that Victoria Day weekend has come and gone, many floriculture greenhouses find themselves with a rare period of empty compartments or benches before fall crops go in. Similarly, many vegetable greenhouses extending their growing period are facing their first crop clean out. Now is the perfect time to consider a thorough cleaning of your greenhouse to prevent pest issues going forward into the new crop. But this can seem like a daunting task.

OMAFRA and the Vineland Research and Innovation Centre have produced a how-to video on greenhouse clean-out and disinfection that can help you know where to start.

GrowON Webinar “Squeaky Clean Start to 2023” Now Available on Demand.

Getting off on the right foot in the new year is important personally AND in your greenhouse, especially when it comes to pest management.

Two of our Canadian greenhouse experts gave some great talks on where, when and how to sanitize in your greenhouse to avoid pest outbreaks, and new research findings on dipping vegetative cuttings to reduce incoming pests.

If you missed this webinar last week, see how you can watch a recoding of this Grow ON Webinar, below.

Looking Ahead to 2023: Preparing for Spring Crops

This post was jointly written by Dr. Chevonne Dayboll and Dr. Sarah Jandricic

It’s hard to believe, but as the first snow hits the ground here in Niagara, that means its time to think about spring crops again!

This post gathers some of the most important things to plan and prep for in the greenhouse, including ordering inputs, preventative maintenance, and your pest management and PGR plans!

Think of this post as your “to-do” check list for the month of December, as the time to plan all this is NOW, before your spring production begins.

We’ve also linked to some helpful videos we’ve recorded from our GrowON webinar series that are relevant to spring crops. They’re worth a re-watch – or a first watch – if you haven’t seen them before!
