Christine – VIU Horticulture Poinsettia Production 2020
VIU Commercial Greenhouse Data
Below are the heights as record by Team Citrus on August 27, 2020. I used a number of different configurations with the set up of the graphs to test which one displayed the information I want to showcase the best.
Moving forward I will use the configuration shown in below from the 6″ Alpina crop. I used the calendar dates on the x axis and took a screen shot from full view.
Height tracking system set up by Team Citrus August 27, 2020.
The 4” and 6” poinsettias are both measured and tracked using the same manual measuring method. Students measured the poinsettias, averaged out the heights, and reported them to Christine. Christine recorded them in the graphical tracker and posted them on her blog.
Students should track, measure, and record the same plants every week using these markers:All sample plants had a tall flagging stick with an orange or green flag marked with a number, 1-10.
To measure the height of the selected plants, students used a handheld ruler (you can use your gnome ruler for this – gnomes encouraged in pictures) and placed it at the bottom of the pot, at bench level. Then students used a pencil pointed it directly across to the ruler to get an accurate measurement. Students measures to the base of the leaf of the tallest stem, not the tallest leaf, and took the measurement there. Students recorded all measurements in centimetres. Students made sure to place the measurement in the data chart under the same sample number every week.
This how-to video describes the steps to successfully transplanting poinsettias. The students transplanted the poinsettias in week 33 and placed them pot to pot in zone 4. We turned on the bottom heat to 23C and did our best to maintain humidity at 60%-70% and temperatures of 18C-23C despite the high outdoor temperatures.
We will be using the Dummen-Orange graphical height tracker for greenhouse and home poinsettia crops. Students will gather greenhouse data while in face to face classes and use the same height tracking techniques for their home crops.
After we pinch the poinsettias, you will be required to measure your poinsettias weekly and input the data into the online graphical height tracker. Once complete, you can import the data from the graphical tracker in your blog to showcase your plant growth through out of the duration of the crop. See the Drummen-Orange link below and on VIULearn and set up your graphical tracker for your crop.
