Catfacing of tomatoes? Is this a Halloween joke way too out of season? Or the subject of a PETA investigation?

I’ve had a number of calls about this phenomenon lately. It’s one of the physiological disorders of tomatoes that we can’t do much about. Generally the fruits are misshapen with large scars and holes at the bottom or blossom end. The fruit can appear distorted in a variety of shapes. There’s a pretty good picture at a Purdue website, http://www.ppdl.purdue.edu/ppdl/images/catfacing-tomato.jpeg but that’s only one of a variety of forms it may take. Some folks think it resembles blossom-end-rot.

This situation is thought to be caused by cool weather at the time of flower pollination and fruit-set. Apparently parts of the flower get stuck together and subsequent development is deformed. Because we had some cool weather a few weeks ago (remember?) that fits our situation and the problem should probably not continue as other fruits develop.

If the problem continues, then you may want to look at a picture of blossom-end rot, http://www.hort.purdue.edu/rhodcv/hort410/8006.jpg

If you find catfacing or one of the other problems in your garden this weekend, they may develop into edible fruit although some parts will have to be cut off. Or you may want to remove them to the compost pile and concentrate the plant’s energy on growing the perfect fruit you anticipate. If you find blossom-end rot (BER) and don't know about it, learn about it at http://www.ces.ncsu.edu/depts/hort/hil/hil-8107-a.html And everyone, be aware that (BER) can also affect other vegetables - such as melons, peppers, and squash.

Happy weekend
