This post on poinsettia problems was contributed to by Drs. Chevonne Dayboll and Sarah Jandricic.
When poinsettias get problems, they always seem to hit hard and fast. Things like whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop. This is why scouting might be more important in this crop than any other.
Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.
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.
This is the second blog post 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. Posts over the next few weeks will focus on identifying problems, interpreting lab tests, on-farm disease monitoring, and water treatment options. These will be good refresher resources, so make sure to bookmark them.
When it comes to talking about disease-related issues in greenhouse crops, one point of confusion is often oven WHICH pathogens CAN be transmitted by water. Some are obvious – we all know Pythium is water-borne. But what about other culprits, like Fusarium or Erwinia? Should you worry about these in your recirculating water?
Read more to find out when to suspect your irrigation water versus other factors when it comes to disease.
Are you aware that the Save on Energy program can help you to complete energy efficient upgrades in your greenhouse? You may have participated in this program in the past, but the current iteration can help you to retrofit items like ventilation fans and upgrade to LED lighting in the warehouse and the greenhouse.
The IESO has developed tools that can help you identify areas where an upgrade might be able to help you save energy. These include a checklist that walks you through the greenhouse, and some videos and other information on their web page.
Once again, Focus Greenhouse Management and Jeffery’s Greenhouse are partnering to bring us the 2019 Poinsettia Open House!
There will be presentations on pest management in poinsettia, troubleshooting production issues as well as plant growth regular trials. And, as always, there will be lots and lots of poinsettia varieties to look at!
Read on for more details including speakers and sales reps that will be present.

If you are using Saturated Paste Extract (SPE) to assess soil nutrients for in-ground grown cut flowers, you may be underestimating plant available nutrients and applying fertilizers that aren’t needed.
Many greenhouse growers use SPE analysis when testing growing media in the greenhouse for nutrient levels. Typically, SPE tests are used in soilless or peat-based growing substrates, the kind we usually see used in potted plant production. However, if you are growing cut flowers in a mineral soil, either in the greenhouse or outdoors, SPE is not giving you a complete report on nutrients available to your crop.
Both greenhouse and outdoor soils that produce cut flowers should be tested on a regular basis.
