This is a joint post on poinsettia issues by Drs. Chevonne Dayboll and Sarah Jandricic.
Okay, so Poinsettia don’t really get that many problems. But when issues arise, they can hit a crop fast and hard. Whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop.
Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.

Do you grow hardy mums and hydrangeas outdoors? If so, this blog post is for you! Flowers Canada Ontario, the Soil Resource Group and OMAFRA have collected data about fertilizer and water management in outdoor greenhouse crops over the last few summers, and have some updated production information for growers to think about over this year’s season.
The goal of the study was to look at ways to improve fertilizer and irrigation efficiency outside of the greenhouse. Continue reading “Tips and Tricks for Outdoor Mum and Hydrangea Production this Summer”

Spring is here, and we know you’re busy! Here’s a quick but very important refresher on fertilizer injector maintenance. Ensure they’re working properly on a regular basis to avoid extra headaches.
How do I know if my injector is working properly?
Hopefully damage to foliage wasn’t your first sign things were a little off! Some things to remember:
- The dilution ratio needed for each application should be known and adjusted as needed.
- Remember that tracing dye in water-soluble fertilizers should never be used as an indicator of the actual strength of a fertilizer mixture.
- If you are using multiple products or chemistries ensure they are compatible for tank mixing before running them through the injector.
- If deviations greater than 5% from the expected setting occur, contact an irrigation specialist for assistance or repair. (But first, double check that math!)
Fertilizer injectors come in all shapes and sizes in the greenhouse.
There are two common methods to check if your injector is working as expected. Regular calibration is needed to ensure that an injector is operating properly. You should complete both methods listed here to ensure accuracy. Continue reading “A Reminder about Fertilizer Injector Maintenance”
