Poinsettias are here! In the next few posts we’ll be breaking down production into into 4 key growing periods: Receipt/Propagation, Early Production, Late Production, and Finishing.
This post on propagation will cover things you can do now to treat pests and diseases in your cuttings to prevent BIG problems later. And make sure to check out Dr. Chevonne Dayboll’s previous post on ensuring cutting quality.

This post on propagation will cover things you can do now to treat pests and diseases in your cuttings to prevent BIG problems later. And make sure to check out Dr. Chevonne Dayboll’s post from last week, on ensuring cutting quality.

Several diagnostic labs in the Northeast U.S., as well as our own lab here at the University of Guelph, have received diseased calibrachoa suspected to have chili pepper mild mottle virus (CPMMoV). The supplier has alerted growers of this issue.
Although CPMMoV is NOT a regulated disease by CFIA or the USDA, it can still affect the quality of your crop and lead to losses.
Read on for a link to an excellent blog post on the topic written by Michigan State University Extension. This includes symptoms to look out for, the importance of testing, and what to do if you have it.

Rot rots like Fusarium, Pythium and black root rot are often the bane of spring bedding crops. Dr. Mary Hausbeck, a Distinguished Professor from Michigan State University, is going to share her vast knowledge on this topic, including which fungicides work best. Check out the details below, and don’t forget to register!

This is the fourth article in a series about water sanitation. The goal of this series is to get you reflecting on your own irrigation system before you are faced with a problem. The first post covered where problems are likely to occur in your greenhouse ; the 2nd covered the types of pathogens found in water and the 3rd covered where and how to sample your water.
Once you’ve got your water sample, this post will cover why water DNA tests are useful, and how to interpret the results. This is the next step towards identifying and then treating your water issues to prevent unnecessary fungal or bacterial disease in your greenhouse crops, and potentially save you thousands of dollars in crop losses or fungicide applications.
These posts make good refresher resources, so make sure to bookmark them!

Now that poinsettias are safely tucked into their prop trays and the threat of Erwinia (Pectobacterium) is almost over, it’s time to think about other poinsettia issues.
Root rots, nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop.
Read on for common pitfalls and how to avoid them, and for some great video resources on poinsettia production.
Dealing appropriately with water issues is arguably one of the most important concerns facing today’s horticultural sector. There are numerous regulations at municipal, provincial and federal levels that govern access to water as well as the implications associated with run-off water.
Growers have responded by constructing elaborate pond and water recycling systems but are now challenged to maintain the quality of water in their pond systems to keep their modern irrigation systems operable.
In this webinar Dr. Jeanine West will share water quality management strategies based on her expertise and preliminary research findings. Time will be allocated for Q&A. Keep reading for registration information.

After reading the previous posts in this series, you’re now aware of WHICH pathogens can be spread through your irrigation water, WHERE they can accumulate, and WHY that’s important. We’re now moving on to posts covering WHAT you can do about it!
This post will walk you through how to sample water sources on your farm, and which tests you can run to determine if your water is helping – or hurting – your crop.

How do you get help in this day and age when your extension agent or consultant can’t just pop into your greenhouse and look at a problem with you? Although nothing can replace seeing an issue first-hand, there is still a way to get help with your pest and production issues from a distance.
This post will give you tips on key information you need to send, and how to take good photos, to make getting quick and accurate answers from experts easier via email or messaging.
