In this first part, Dr. Healy takes a deep dive into Nutrition. As he explains, when it comes to poinsettias, if you have the nutrition right, most of your problems will be greatly reduced. We start with an overview of the importance of monitoring EC and pH and quickly get into the nitty gritty details of how to approach feeding your crop, the benefits of front-loading fertilizer and even why withholding feed is a bad strategy. Will does a great job explaining how your feeding decisions impact the EC of the crop, as well as how feed leads to excellent or poor crop presentation at retail. If you are wondering what to do if EC starts to creep up, be sure to listen all the way to the end.
We also spend time on pH and what can be gained by staying in the optimal 5.8 to 6.2 range. One of the most applicable parts of this episode is Dr. Healy’s explanation of how to determine crop needs based on the size of leaves on the plant and how you can effectively measure them using your two hands! As we wrap the episode up, Will talks about watering and shares some poinsettia specific watering strategies. As I mentioned before, you are going to want to listen this one all the way to the end. And also, share it with your entire poinsettia team because when you’re all on the same page, good things will happen.
