Tomato – Catfacing
Q: My Brandywine tomatoes look like some kind of mutants. The plant started off looking very healthy and was mulched and fertilized as I have always done. The first tomato harvested looked ok but did not have a good taste or texture.
A: The odd shape is called catfacing. It seems to be caused by cool or hot temperatures during pollination and fruit set. It can also be caused by too much fertilizer.
Big-fruited varieties are more prone to the condition than medium-fruited varieties.
Don’t set out your plants too early in spring.
