Today I was the alternate waterer for the class, which meant that I did the watering for everyone else who didn't show up. I noticed that some of the plants in each student's group of poinsettias had dried out completely, while others were still a little moist. After the weekend watering is critical, but I think so is Friday. Perhaps all my plants should get a good dose of water, whether they need it or not, to ensure that they have adequate reserves to cover the weekend.
