I have three tomato plants in the greenhouse, a Rutgers, a Brandywine, and a Super Beefsteak. They are growing in large pots. Only the Brandywine looks to be normal. The other two have developed some kind of leaf curl in which the leaf rolls up and the underside of the leaf turns dark purple.
I fear that cats may have gotten into the greenhouse and whizzed in those two pots. Does anyone have the key to this mysterious 'mater malady?
