It seems that all the tomato conversation lately has been about blossom end rot. The Plant Clinic reports that numerous examples have come in concerning it in tomatoes, squash, eggplant, and peppers. The gardening hotline at the Extension Office is buzzing with rot questions. There’s obviously a lot of rot going around.
So what is this nasty sounding ailment? It starts at the end where the blossom was and begins turning tan, then a dry sunken decay sets in. The lesion enlarges, turns to dark brown to black and becomes leathery. Thus the blossom end begins to rot.
It shows up especially in the first fruit of the season and after the fruit is well on its way to development. In severe cases, it may completely cover the lower half of the fruit. Both green and red fruit develop it. It’s not a pest, parasite or disease process but is a physiological problem caused by a low level of calcium in the fruit itself. In other words, dear gardener, IT’S ALL YOUR FAULT!
