Hopefully you’ve read our previous post on pest management in propagation. Now it’s time to cover poinsettia IPM during early production.
This post will cover the first signs of root rots, as well as whitefly and Lewis mite monitoring and management. As healthy plants are better able to defend themselves from pests and diseases, we’ll also give a quick nutrient refresher.

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!
