Last week the question was: What is wrong with this watermelon?
There are two things wrong with this watermelon. The first is blossom end rot. This is a localized calcium deficiency that is usually caused by an inconsistent water supply. The second problem is poor pollination. This is what is causing the gourd-like shape to this watermelon. To achieve good pollination and shape, each female flower needs about 1000 grains of pollen which is achieved from about 8 visits. For more information on pollination, take at look at this page, and for more info on blossom end rot, look at this one.
Here is this week’s question: How many individual fibers are in a cotton boll?
